Thirteen lichen species from 7 genera have been identified from Bario. The major metabolites present in these species were determined by thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC). Introduction Bario lies 1200 metres above sea level, on a plateau in the Kelabit Highlands, southeast of Miri in the Fourth Division of Sarawak. It is bordered by the Tamabu Range in the west and the Apo Duet Mountains to the east. It has a mild and cool climate, with temperatures of 18-22°C and an annual rainfall of about 2213 mm. Knowledge of the lichen flora of Malaysia, especially of Sabah and Sarawak, has made great progress during recent years. Din et at. (1997) recently presented a comprehensive account of the lichen flora of Malaysia, summarizing the results of many research efforts undertaken by scientists at several collecting localities in Peninsula Malaysia, Sabah and Sarawak. In May 1995, a scientific expedition was carried out in Bario, Sarawak. The gen...

Suharno, Chrystomo LY, Sujarta P, Tanjung RHR. 2020. Rapid assessment of lichen diversity in Baliem Valley, Jayawijaya, Papua, Indonesia. Biodiversitas 21: 2403-2409. Lichen is a form of mutualistic symbiosis between phycobiont and mycobiont. Lichens play an important role in environment, either to maintain the biological diversity and the function of ecosystems. This study is aimed to determine the diversity of species of lichens in the Baliem Valley region, Jayawijaya, Papua. The method used was explorative surveys in several villages in Jayawijaya District. Species identification was based on morphological characteristics. The results showed that there were 37 species of lichen belong to 24 genera and 11 families on several habitats on altitude ranging from 1655 to 2179 m asl with temperatures between 18-26°C. The dominant species were from the families of Parmeliaceae, Cladoniaceae, and Teloschistaceae. The results indicate that the Baliem Valley region rich in lichen diversity ...

2007). New lichens from Thailand, mainly microlichens from Chiang Mai. Fungal Diversity 24: 75-134. Results from collecting trips in Chiang Mai and other Provinces of Thailand are reported here. Excluding new species described here the paper includes about 300 species new to Thailand, six of which are first records for the Northern Hemisphere of species described from Australia or Papua New Guinea A few species are reported here for the first time since their original description, such as Bacidiopsora orizabana, which was known only from Mexico, but is here reported from Thailand and Taiwan. Concentration on specific groups of crusts led to the identification of three yellow crusts which are usually found sterile. One was identified as the pycnidial form (with stalked pycnidia) of Piccolia conspersa. The others are described below as Pyrrhospora luminescens Aptroot & Wolseley, Rinodina citrinisidiata Aptroot & Wolseley (also reported from Yunnan, China). A pantropical lichen with an...

Coccocarpia palmicola is widespread in both New Zealand and Australia. It’s a common epiphyte in humid lowland forests, but also invades bryophyte turves and colonizes clay banks. Its gun-metal grey colour can vary with exposure and altitude.

Maliau Basin Conservation Area is located in south-central Sabah on the island of Borneo. It is a rugged and uninhabited forested area with steep slopes up to 1500 m in elevation. The basin (c. 390 square kilometres in area) is drained by a series of radiating tributaries of the Maliau River. For the most part, the vegetation comprises tropical submontane dipterocarp forest, but that intergrades into heath forest at higher elevations. In this paper, we report on 24 lichens collected from Maliau Basin, six of which are new records for Malaysia. The following is common to all specimen citations: Malaysia: • Sabah: Maliau Basin, Eucalyptus Camp, 4°52’18”N, 106°49’35”E, c. 1000 m, ix.2006 (CANB, UKM).

Pyrenulaceae from Lord Howe Island, Norfolk Island and the Cocos (Keeling) Islands André Aptroot ABL Herbarium, G.v.d.Veenstr. 107, NL-3762 XK Soest, The Netherlands Abstract: New records of Pyrenulaceae are reported from Lord Howe Island (11) and Norfolk Island (14) in the south-western Pacific Ocean. Pyrenula ochraceoflava is the first lichen to be reported from the Cocos (Keeling) Islands in the Indian Ocean. Previous records from Norfolk Island are rejected. Introduction A continuing investigation of Australian Pyrenulaceae for the Flora of Australia has revealed many collections from Lord Howe Island and Norfolk Island, and one from the Cocos (Keeling) Islands. Thus far, only the presumed endemics Lithothelium austropacificum P.M.McCarthy (McCarthy 1996) and Pyrenula howeana Aptroot (Aptroot 2007) are known from Lord Howe Island. The two species previously reported from Norfolk Island, P. nitida (Weigel) Ach. and P. ravenelii (Tuck.) R.C.Harris (Cheel 1904, Elix & McCarthy 1998), are based on misidentifications. The former does not occur in the Southern Hemisphere, and the latter is found in Australia only at temperate latitudes. A total of 14 corticolous species of Pyrenulaceae are reported here for the first time from Norfolk Island, and 11 from Lord Howe Island. Moreover, Pyrenula ochraceoflava is the first lichen to be reported from the Cocos (Keeling) Islands in the Indian Ocean. In most cases, only selected specimens are listed below. For more information on taxonomy, synonymy and distribution, see Aptroot (2007) and McCarthy (2007). Seven species of Pyrenula and Lithothelium are known from Christmas Island, an Australian territory in the Indian Ocean (McCarthy 2007), including the endemic L. quiescens P.M.McCarthy.

Staiger & Kalb, Graphis analoga Nyl., Graphis virescens Müll. Arg., Hemithecium implicatum (Fée) Staiger and Phaeographis colligata (Stirt.) Zahlbr. are reported as new to Australia. An examination of recent collections from northern Australia and elsewhere has shown the presence of five species of Graphidaceae not previously reported from Australia: two of Graphis and one each of Acanthothecis, Hemithecium and Phaeographis. The species were identified by microscopic examination, the identification of secondary lichen products (where present), and comparison with published descriptions. Acanthothecis tetraphora (Nyl.)

Fig. 1 Type: Nova Granata [Colombia] Canoas, Tequendama, Lindig s.n., ix.1860; (holotype – H-NYL 6124 pro parte maxima) Thallus corticolous, off-white to yellowish white, thin, the surface minutely powdery. Apothecia lirelliform, sparse, scattered, inconspicuous, sessile, concolorous with the thallus or becoming pale pink, lips closed or becoming slightly open, simple, straight, curved or sinuous, 0.7–2 mm long, 0.3–0.4 mm wide. Exciple non-carbonized, inconspicuous. Hymenium 100–130 µm tall, I–, not inspersed. Ascospores 4 per ascus, narrow, elongate-ellipsoid, hyaline, muriform, 57–70 µm long, 10–15 mm wide, 19–24 x 3–4-locular, I–. Chemistry: norstictic acid. This species is characterized by the non-carbonized exciple, the non-inspersed hymenium, the narrow muriform ascospores giving no reaction with iodine, and the presence of norstictic acid. It is distinguished from other Acanthothecis species in Australia with muriform ascospores by its larger ascospores. It is known in Australia from the one specimen; it also occurs in Brazil, Colombia and Kenya (Staiger 2002).

Type: Taiti [Tahiti], Vieillard & Panchet s.n.; (holotype – H-NYL 7432). Thallus corticolous, pale fawn, surface smooth and dull, somewhat cracked. Apothecia lirelliform, numerous, conspicuous, semi-immersed with a conspicuous thalline margin, simple, straight, curved or sinuous, or sometimes branched, 1–3 mm long, 0.15–0.3 mm wide, lips closed. Exciple laterally carbonized, largely concealed by the 8 AUSTRALASIAN LICHENOLOGY 62, January 2008 AUSTRALASIAN LICHENOLOGY 62, January 2008 9 thalline margin. Hymenium 100–120 µm tall, not inspersed, I–. Ascospores 6–8 per ascus, ellipsoid, hyaline, muriform, 22–35(–40) µm long, 10–16 mm wide, 4–7 x 1–3 locular, I+ blue. Chemistry: norstictic acid (major) and connorstictic acid (minor). This species is characterized by the laterally carbonized exciple, the non-inspersed hymenium, the presence of norstictic acid and the muriform ascospores. It resembles Graphina gracilis (Fr.) Müll. Arg. (Müller 1887), but that species is reported to possess sulcate lirellae (Müller loc. cit.). The Australian specimen somewhat resembles G. analoga var. subtecta Nyl., which Nylander (1863) reported to differ from the type by the “somewhat covered lirellae and the larger spores [saepius subtectis et sporis majoribus, 27–48 x 11–16 µm]” (Nylander 1863), but because Nylander reported a range of ascospore sizes from 18 µm to 80 µm long (vide infra) the specimen is retained as var. analoga. In the protologue, Nylander (1859) reported the ascospores to be 18 µm long and 8 µm wide, but later he (Nylander 1869) reported them to be 46–80 µm long and 18–30 µm wide. Subsequently, Awasthi & Singh (in sched. 1975) reported the ascospores in the type specimen to be 20–30 x 8–12 µm, Vainio (1921) gave the dimensions as 21–38 x 7–13 µm, and Redinger (1933) reported 24–40(–57) x 12–15 µm, all three of those reports not differing markedly from the ascospore dimensions observed in the Australian specimen. Originally described from Tahiti, Graphis analoga has also been recorded from Hong Kong (Aptroot & Sipman 2001), the Philippines (Vainio 1921), Brazil (Redinger 1933) and Indonesia (Redinger 1936).

This species is characterized by the greenish thallus, the conspicuous, sessile, simple lirellae, the non-inspersed hymenium and the absence of lichen compounds. It is morphologically similar to Graphis emersa Müll. Arg., but that species contains norstictic acid, and to G. anfractuosa (Eschw.) Eschw., which differs in having an inspersed hymenium. Graphis geraensis Redinger also has a completely carbonized exciple, ascospores similar in size to those of G. virescens, and has no lichen compounds, but it lacks the greenish thallus and robust, simple lirellae without a thalline margin; in contrast, G. virescens has slender lirellae with a thalline margin. Graphis virescens was previously known from Brazil (Staiger 2002). SPECIMENS EXAMINED Queensland: • Bunya Mountains National Park, summit of Mt.

Bot. France 21, 27 (1874). Type: Brazil, A. Glaziou 5036; (isotype – MICH fide Wirth & Hale 1963). Graphis chlorocarpella Nyl. in A. Krempelhuber, Flora 59, 413 (1876). Type: Brazil, Rio de Janeiro, A. Glaziou 5036; (holotype – H-NYL 7723 fide Staiger, loc. cit.). Thallus corticolous, pale fawn, surface smooth and dull. Apothecia lirelliform, inconspicuous, pale orange-brown, scattered, initially fissurine, becoming slightly raised, simple, straight, curved or sinuous, or rarely branched, 1–2 mm long, 0.1–0.2 mm wide, lips closed. Exciple non-carbonized, pale orange-brown. Hymenium 80–100 µm tall, I–, not inspersed. Ascospores 8 per ascus, elongate-ellipsoid, hyaline, 30–40 µm long, 6–8 µm wide, 9–12-locular, I+ blue. Chemistry: no lichen compounds detected. The species is characterized by the thin inconspicuous, initially fissurine, pale orangebrown lirellae, the Graphis-like ascospores and the absence of lichen compounds. The lirellae are thin and inconspicuous when compared with other species in the genus such as H. aphanes (cf. Archer 2006: 173, Fig. 81). Staiger (2002) reported the ascospores to be 40–50 x 8–10 µm and 12–15-locular, whereas Nylander (in Krempelhuber 1876) reported the ascospores to be 36–39 x 8–9 µm and 12-locular. Nylander rejected Fée’s epithet as unsuitable, and based his species G. chlorocarpella on the same type material as Fée’s G. implicata (Nylander in Krempelhuber 1876); G. chlorocarpella thus becomes a later synonym (Staiger 2002). The species is also known from Brazil and French Guiana, and from Mexico (Wirth & Hale 1963). SPECIMEN EXAMINED: Western Australia: • Mitchell Plateau, 14°53’S, 125°50’E, on tree trunk with smooth bark in vine thicket, R. Hnatiuk MP196D, 25.vi.1976 (PERTH 02898071). Phaeographis colligata (Stirt.) Zahlbr., Cat. Lich. Univ. 2, 366 (1924) Fig. 5 Graphis colligata Stirt., Proc. Philos. Soc. Glasgow 12, 185 (1881)[1882]. Type: India, Assam, A. Watt s.n., 1879; (lectotype – BM fide Singh & Awasthi 1979). Thallus corticolous, off-white to pale fawn, surface smooth and dull. Apothecia lirelliform, numerous, crowded, conspicuous, in stellate clusters to 2 mm diam., individual lirellae 1–1.5 mm long, 0.1–0.15 mm wide, terminally acute, lips open. Exciple dark brown, thin, complete. Epithecium matt brownish black, epruinose. Hymenium 80–90 µm tall, I–, inspersed. Ascospores 8 per ascus, pale brown, oblongellipsoid, 16–18 µm long, 6–8 µm wide, 4-locular. Chemistry: norstictic acid (major) and connorstictic acid (minor). This species is characterized by the stellate lirellae, the small 4-locular ascospores, the presence of norstictic acid and the inspersed hymenium. It resembles P. brasiliensis (A. Massal.) Kalb & Matthes-Leicht and P. inconspicua (Fée) Müll. Arg.; both of those species have open lirellae and small 4-locular ascospores, and they contain norstictic acid, but neither has an inspersed hymenium. It also resembles P. inusta (Ach.) Müll. Arg., but that species lacks both an inspersed hymenium and norstictic acid. Singh & Awasthi (1979) reported the hymenium to react I+ pale blue, but this was not found in the specimen cited above, in agreement with Stirton’s observation in the protologue “Iodo gel. hym. pallide rufescens vel non tincta” (Stirton 1882). This species occurs in Assam and West Bengal, India (Singh & Awasthi 1979), but previous reports from Christmas Island and Fiji (Archer 2003) were erroneous because the specimens lacked norstictic acid.

On March 12–15 (Wednesday–Saturday) of this year, a Thelotremataceae workshop will be held at Ramkhamhaeng University in Bangkok, Thailand, organized by Kansri Boonpragob (Bangkok) and Thorsten Lumbsch (Chicago). The workshop is intended for East Asian students who have a general interest in lichens as well as students from outside the region with a particular interest in tropical crustose lichens. Up to 25 can attend. The workshop is financially supported by the National Science Foundation. Wednesday will be devoted to talks: general lectures on Thelotremataceae biology and taxonomy, and recent studies in the family. To date, speakers include Klaus Kalb (Neumarkt), Robert Lücking (Chicago), Armin Mangold (Essen), and Khwanruan Papong (Khon Kaen), as well as the two organizers. Colleagues who wish to contribute oral presentations should contact Thorsten for more information. A field trip to the Khao yai National Park is planned for Thursday and Friday, with an overnight stay in the park. On Saturday, the collections will be identified and discussed. On March 10–11 (Monday and Tuesday), a preliminary course will be offered to students with only limited experience of lichens. Monday will be an introduction to lichen taxonomy and identification methods, and Tuesday will be a practical course. For local information, contact Kansri (e-mail: kansri@ram1.ru.ac.th) Dr H.

The meeting will begin at 9 a.m. Saturday at the Regional Office of the Department of Sustainability and Environment (DSE). You can park all day on Service Street at the rear of the building, or you can park in the DSE carpark on the corner of Service Street and Franklin Street (see below for a link to an on-line map). Enter the building at the front on Hotham Street. Several talks are scheduled for Saturday morning, with fieldwork following in the afternoon at Morwell National Park. The park lies 25 km SSW of Traralgon, and contains remnants of the original Strzelecki Ranges forest, including wet forest with fern gullies and drier stringy bark vegetation. A group dinner is planned for the evening. Sunday will be devoted to fieldwork in the Baw Baw Ranges. Departure will be at 8:30 a.m. from the DSE Office in Traralgon. The main collecting site will be subalpine granite outcrops called Mushroom Rocks. If time permits, we’ll stop at other sites, but we plan to be back in Traralgon by 3 p.m., where the meeting will end. The DSE and Parks Victoria have issued a permit for small personal collections at the fieldwork sites during the two days of the meeting. A preliminary announcement of the meeting appeared in the last issue (Volume 61) of Australasian Lichenology. If you wish to attend, please contact Simone Louwhoff by March 20 with details of which days you’ll attend (Saturday, Sunday, or both), and if you plan to attend the dinner, plus if you need transport on the fieldtrips, and if you’d like to present a talk.

Elix School of Chemistry, Building 33 Australian National University, Canberra, ACT 0200, Australia e-mail: John.Elix@anu.edu.au Sergey Y. Kondratyuk M.H. Kholodny Institute of Botany, Tereshchenkivsjka Str. 2, 01601 Kiev, Ukraine e-mail: ksya_net@ukr.net Abstract: Letrouitia hafellneri S.Y.Kondr. & Elix and L. leprolytoides S.Y.Kondr. & Elix are described as new to science and are compared with allied taxa. A key to the sorediate and isidiate species of Letrouitia is provided. The examination of various collections of crustose lichens in preparation for a further lichen volume of the Flora of Australia has led to the identification of two undescribed species, namely Letrouitia hafellneri S.Y.Kondr. & Elix and L. leprolytoides S.Y.Kondr. & Elix. Chemical constituents were identified by high-performance liquid chromatography (Elix et al. 2003) and comparison with authentic samples. Letrouitia hafellneri S.Y.Kondr. & Elix, sp. nov. Figs 1, 2 Sicut Letrouitia domingensis sed superfice isidiatis et sorediatis differt. Type: Australia. Queensland: Machans Beach, a few km N of Cairns, 16°51’S, 145°45’E, 3 m, on an old mangrove along the Barron River, K. & A. Kalb s.n., 26.viii.1988, (holotype CANB; isotype herb. Kalb). Thallus up to 10 cm wide, dull to bright yellow or yellow-grey, K+ slowly purple, thin, continuous to areolate; soredia and isidia present. Areoles 0.3–0.5 mm wide, more apparent near the margins. Isidia very thin, 60–70 µm diam., up to 0.3 mm high, simple or branched and becoming coralloid, forming dense aggregations in places. Soralia 0.5–1.5 mm wide, ±orbicular, forming a convex sorediose mass. Soredia very fine at first, (12–)15–20(–25) µm diam., powdery, of irregular shape with numerous pigment granules on the surface, soon becoming aggregated in the larger, ±rounded or irregular aggregations (25–)40–55 µm diam. Hypothallus not apparent. Apothecia dispersed, round to somewhat distorted, thick (to 0.45 mm) and rising above level of thallus, constricted at base, 0.5–1.0 mm wide; disc concave at first, yellowish brown or ±yellowish pruinose, then flat and dark orange-brown to dark brown or blackish brown; margin prominent, thick, 0.1–0.15(–0.2) mm wide, bright yellow at first but soon becoming orange to brownish orange, disc and margin K+ blue-violet (appearing black under the microscope); proper exciple (in cross-section) up to 200 µm thick in the uppermost and lower lateral portions, with numerous anthraquinone crystals in the inner layers; outer layers K+ violet. Epihymenium encrusted with orange anthraquinone crystals, K+ violet. Hymenium colourless, 100–110 µm high. Paraphyses conglutinated, usually branched sparingly, not expanding towards the tips, c. 2 µm diam. Hypothecium colourless, 40–50 µm thick. Asci 8-spored. Ascospores ellipsoidal, transversely septate with 6–8 lens-shaped locules, 25–37 x (9–)11–14(–15) µm in water, becoming longer in K, 27–46 x (10–)11–14(–15) µm. Conidia long, bacilliform, 4–6(–7) x 0.9–1 µm. Chemistry: Thallus and apothecia K+ blue-violet; containing fragilin (major), ±parietin (minor), ±7-chloroemodin (trace), ±7-chloroemodinal (trace), ±7-chloroparietinic acid (trace), flavo-obscurin A (minor), ±physcoin bisanthrone (trace). Etymology: This species is named in honour of the well-known Austrian lichenologist Josef Hafellner, author of the world monograph on the genus Letrouitia. 16 AUSTRALASIAN LICHENOLOGY 62, January 2008 Remarks This new species is distinguished by the simultaneous presence of true isidia and soredia on the upper surface. Both L. corallina (Müll. Arg.) Hafellner and L. leprolyta (Nyl.) Hafellner have isidia, but lack soredia and have different ascospores. Thus L. corallina has 2-spored asci with much larger (45–58 x 16–21 µm) submuriform ascospores. Letrouitia hafellneri differs from L. leprolyta in having longer, mainly 8-locular (6-locular in L. leprolyta) ascospores (25–37 µm vs. 18–30 µm long), as well as in having soralia. Letrouitia coralloidea (Müll.Arg.) Hafellner is sorediate [but is so far known only in the sterile state], but the soredia are larger (20–50 µm vs. 12–25 µm diam.), and it lacks isidia. The chemistries of these taxa are essentially identical (Johansson et al. 2005). The apothecia and ascospores of L. hafellneri are very similar to those of L. domingensis (Pers.) Hafellner & Bellem., but the latter lacks soredia and isidia. SPECIMEN EXAMINED Queensland: • Ellis Beach, 27.4 km N of Cairns, 16°44’S, 145°39’E, 1 m, on trees along the foreshore, J.A.

Etymology. The specific epithet derives from the Greek -oides (resembling or having the form of) and L. leprolyta, the species that the new taxon most closely resembles. AUSTRALASIAN LICHENOLOGY 62, January 2008 17 Remarks This new species is distinguished by the presence of finger-like to coralloid isidia on the upper surface, (4–6–)8-spored asci and (4–)6(–8)-locular ascospores. This species has previously been confused with L. leprolyta, but re-examination of the type material has confirmed that the latter has short, wart-like or erumpent isidia (0.1–0.15 mm wide and 0.1–0.2 mm long), whereas L. leprolytoides has cylindrical, finger-like to coralloid-branched isidia (50–70 µm wide and 0.3–0.4 mm long). In addition, L. leprolytoides differs from L. leprolyta in having mainly (4–6–)8-spored asci and somewhat longer ascospores [(17–)23–30(–31) µm vs. (18–)19–26(–30) µm in water]. We were only able to detect 2–4 well-developed ascospores in asci of the type of L. leprolyta, but other specimens exhibited (2)–4(–8)-spored asci.

This new species is characterized by the whitish, grey-white to grey thallus, the 8-spored asci, the olive-brown to dark brown epihymenium (reacting K–), the relatively small, ellipsoid ascospores (16–23 x 8–14 µm) with relatively weak subapical wall thickenings, a moderately ornamented outer spore wall, and the presence of norstictic and hafellic acids. Hafellic acid exhibits the following Rf values in the standard TLC solvent systems: A 0.50, B 0.32, C 0.33 [the spot appears fluorescent skyblue under long wavelength ultraviolet light after sulfuric acid treatment and charring] (Elix & Ernst-Russell 1993). Hafellia curatellae (Malme) Marbach is superficially similar but differs in having narrower ascospores (15–22 x 6–8 µm vs. 16–23 x 8–14 µm), an epihymenium that often reacts K+ clear yellow-green or olive, a more or less smooth outer spore wall and contains only norstictic and connorstictic acids (Etayo & Marbach 2003, Marbach 2000). 20 AUSTRALASIAN LICHENOLOGY 62, January 2008 AUSTRALASIAN LICHENOLOGY 62, January 2008 21 Verrucaria pluviosilvestris sp. nov., a common lichen of rainforest in north-eastern Queensland Patrick M. McCarthy Australian Biological Resources Study, GPO Box 787, Canberra, ACT 2601, Australia Abstract: Verrucaria pluviosilvestris P.M.McCarthy (Verrucariaceae) is described as new. This lichen is common on sheltered, non-aquatic siliceous rocks of various types in lowland and montane rainforest in north-eastern Queensland. In July and August, 2006, a collecting trip to rainforest and associated habitats between Townsville and Cape Tribulation, north-eastern Queensland, confirmed the significance of pyrenocarpous lichens in the saxicolous communities of creeks and creek-banks, cliffs, gorges and sheltered outcrops. While Porinaceae are especially diverse in the region, species of Anisomeridium, Strigula and Verrucariaceae are also prominent. One previously undocumented Verrucaria is particularly common on nonaquatic rocks, and is described here. 1 Verrucaria pluviosilvestris P.M.McCarthy, sp. nov. Fig. 1 Thallus epilithicus, laevigatus, rimosus vel areolatus, 30–60 µm crassus, albidus vel pallidogriseus, sine strato basali, madefactus pallidoviridis.

True cortex lacking, but the uppermost 10–20 µm of the thallus without algae; cells rounded to angular and vertically elongate, 3–8 x 3–5 µm, hyaline, thin-walled. Algae chlorococcoid, dominating the rest of the thallus (vertical section), bright green, globose, subglobose or ellipsoidal, 5–10(–12) x 4–8(–10) µm; interstitial cells similar to those of the alga-free layer. Prothallus not apparent. Basal layer absent; however, overlapping involucrellum bases in abundantly fertile thalli can give the misleading impression of a thick continuous layer of blackish basal hyphae. Perithecia usually very numerous, almost entirely immersed in the thallus, with only the upper part of the involucrellum exposed; wetting the thallus often shows the full extent of the immersed involucrellum; perithecia less commonly semi-immersed in the thallus. Involucrellum black, (0.2–) 0.38(–0.55) mm diam. [25 measured], usually exposed only towards the apex, c. 40–60 µm thick, contiguous with the excipulum but also spreading laterally into the thallus and towards the substratum. Perithecial apex usually plane to convex, (0.08–)0.15– 0.22(–0.35) mm diam. [50 measured], with a central, hyaline to grey-brown plane shallowly depressed or, occasionally, crateriform ostiole (40–)80(–100) µm diam. Excipulum hyaline to greyish brown in thin section, 20–25(–30) µm thick. Centrum AUSTRALASIAN LICHENOLOGY 62, January 2008 23 subglobose to obpyriform, 0.15–0.28 mm diam. Periphyses 15–30(–40) x (1.5–)2–2.5 µm, simple to sparingly branched. Paraphyses absent at maturity. Hymenial gel IKI+ orange-brown. Asci fissitunicate, 8-spored, narrowly to broadly clavate to cylindroclavate or obclavate, occasionally almost subglobose, 65–115 x 24–40 µm. Ascospores simple, hyaline, narrowly to broadly ellipsoidal, occasionally subcylindrical or broadly clavate, biseriate or irregularly massed in the asci, (22–)31(–39) x (9–)12(–15) µm [80 measured]; wall usually 0.7–1 µm thick, occasionally to 2 µm (due to environmental stress?); contents granulose and, frequently, large-guttulate.

Flora of Australia 58A, 176–196. Etymology: From the Latin pluvius (rainy) and silvestris (of the forest), in reference to the habitat of the species. Remarks The new species is characterized by a combination of very pale areolate thallus, very numerous and largely immersed perithecia, each with a spreading involucrellum, and comparatively large asci and ascospores. The aquatic and semi-aquatic V. praetermissa (Trevis.) Anzi occurs, among other places, in south-eastern and north-eastern Queensland (including the Atherton Tableland). However, while the thallus is outwardly and anatomically quite similar to that of V. pluviosilvestris, it is subtended by a thick brownish black basal layer. In addition, the ascospores are considerably smaller [15–24 x 6.5–9.5 µm; McCarthy (2001)]. The newly described lichen does not grow in creeks or on seasonally inundated rocks. Verrucaria pluviosilvestris was collected from shaded, fine- and coarse-grained siliceous rock outcrops, boulders and cliff faces in rainforest at ten localities between Wallaman Falls (18°35’S) and Mossman Gorge (16°28’S) and at elevations of 55–980 m. It is likely to be as common in similar habitats further south in Queensland.

McCarthy Australian Biological Resources Study, GPO Box 787, Canberra, ACT 2601, Australia Abstract: Melanophloea montana P.M.McCarthy (Thelocarpaceae) is described as new from sheltered siliceous rocks in montane rainforest in north-eastern Queensland. In August, 2006, a remarkable lichen with perithecioid ascomata was collected from siliceous rock in the montane rainforest of the Atherton Tableland in north-eastern Queensland. It is described here as Melanophloea montana (Thelocarpaceae). Melanophloea montana P.M.McCarthy sp. nov. Fig. 1 Thallus epilithicus, rimosus, laevigatus, medioviridigriseus vel griseobrunneus, 30– 50(–80) µm crassus, ecorticatus; algae chlorococcoidea. Ascomata perithecia simulantes, convexa vel hemisphaerica, superficialia, (0.24–)0.35(–0.42) mm diametro, parietibus viridiatris; paries algae includens. Hymenium amyloideum. Pseudoparaphyses simplices vel anastomosantes. Asci c. 150–200-sporae, 70–150 x 12–22 µm, parietibus aeque tenuibus. Ascosporae numerosae, simplices, hyalinae, plerumque ellipsoideae, 4–6(–6.5) x (2–)2.5–3 µm. Type: Australia, Queensland, Atherton Tableland, Ravenshoe State Forest, Tully Falls Weir, 28 km S of Ravenshoe, 17°41’57”S, 145°31’24”E, on deeply shaded, damp siliceous rocks in rainforest, alt. 885 m, P.M. McCarthy 2520, 7.viii.2006 (holotype CANB; isotype HO). Thallus crustose, epilithic, to 4 cm wide, determinate, sparingly to richly rimose but not areolate, smooth, slightly glossy, medium greenish grey to greyish brown, 30–50(– 80) µm thick, ecorticate, tending to peel in places, somewhat pulpy and translucent when wetted. Algae chlorococcoid; cells bright green, globose, (4–)5–7(–8) µm diam., less commonly subglobose to broadly ellipsoidal. Hyphae c. 2 µm wide. Prothallus not apparent; hypothallus absent. Ascomata resembling perithecia, rather numerous, mostly solitary and semi-immersed to almost superficial, convex to hemispherical, (0.24–)0.35(–0.42) mm diam. [50 measured], greenish black, not overgrown by the thallus. Ascomatal apex usually rounded, occasionally somewhat flattened or depressed, with a whitish, grey-green, medium grey-brown or dark brown, (50–)80–120 µm diam. area, viz. the uppermost level of the hymenium. Even when ascomata are uniformly ±black when dry, when wetted the ‘epihymenium’ is visible as a brownish disc. Ascomatal wall with an outer, 20–45 µm thick, greenish black hyphal layer (thinner towards the apex, thicker below), with cells 2–4 µm wide, subtended at the apex by the excipulum and, laterally, by thalline hyphae and algal cells. Excipulum enclosing the hymenium, uniformly hyaline to pale yellowish brown, 20–25(–35) µm thick at the base, 30–50(–60) µm thick near the apex, composed of numerous periclinal layers of thin-walled elongate hyphae. Hymenium subglobose to depressed-ovate, 0.18–0.25 mm diam.; hymenial gel IKI+ blue-black; contents remaining coherent in KOH and water. Subhymenium pale brown to medium orange-brown, 40–60 µm thick. Paraphyses rather sparse at maturity, initially more numerous and simple, becoming sparingly branched and anastomosing, (0.5–)1(–1.5) µm wide. Periphyses absent. Asci obclavate, narrowly clavate to elongate-cylindrical, containing c. 150–200 ascospores, 70–150 x 12–22 µm, IKI+ pale blue; wall uniformly c. 1 µm thick at maturity; apex rounded, apparently lacking dehiscence apparatus, with a very intensely blue cap outside the wall of the apex (G. Kantvilas, pers. comm.); empty post-mature asci remaining visible in the hymenium. Ascospores simple, hyaline, narrowly to broadly ellipsoidal or short-cylindrical, massed in the asci, 4–6(–6.5) x (2–)2.5–3 µm [50 measured], lacking a perispore; contents clear, non-guttulate. Conidiomata not seen. 26 AUSTRALASIAN LICHENOLOGY 62, January 2008 Etymology: The epithet montana refers to the montane habitat in which the species was found. This is in contrast to the lowland habitats of previous collections of Melanophloea. Remarks The previously monotypic Melanophloea was originally characterized by a granulose corticolous thallus with a chlorococcoid photobiont, prominent perithecioid ascomata with a carbonized wall, a hamathecium of anastomosing filaments, an amyloid hymenium, and thin-walled asci containing very numerous, simple, globose ascospores (James & Vezda 1971). Melanophloea pacifica P.W.James & Vezda is known from the bark of rainforest trees in the Solomon Islands and at Cape Tribulation, northeastern Queensland (James & Vezda 1971, Thor 1995). While the newly described species can be accommodated in Melanophloea, placement there is not entirely satisfactory. The saxicolous thallus is thin and rather smooth, the ascomata are less prominent, and while these are externally rather deeply pigmented, in section the ascomatal wall is not ‘carbonized’, and it encloses algal cells. Moreover, the ascospores are ellipsoidal to short-cylindrical. Nevertheless, a well-defined suite of thallus and ascomatal characters confirm Melanophloea as the most appropriate available genus: a chlorococcoid photobiont, a firm involucrellum-like ascomatal wall, anastomosing filaments resembling pseudoparaphyses, the absence of periphyses, a firmly coherent amyloid hymenium, thin-walled multispored asci, and minute, simple hyaline ascospores. Melanophloea montana is more remote from Thelocarpon Nyl., with its pale, often translucent and more fragile ascomatal wall that lacks all traces of an involucrellumlike layer (Salisbury 1966). However, their relationship is confirmed by the morphology of the ascomata which, rather than being true perithecia, are essentially apothecia with an upwardly curved excipulum that encloses the hymenium but which nevertheless leaves a narrow disc of exposed epihymenium consisting of hamathecial filaments and ascus apices (Fig. 1A, B). This lichen is known only from the type locality in montane rainforest in northeastern Queensland. Associated taxa included the locally common pyrenolichens Anisomeridium australiense (P.M.McCarthy) R.C.Harris and Strigula australiensis P. M.McCarthy.

Two other Australian species are outwardly very similar, and also produce elongate, multiseptate spores. Porina rhaphidiophora (Nyl.) Müll.Arg. is known from south-eastern New South Wales, Tasmania, New Caledonia, southern New Zealand and Madagascar; its spores are 9–11(–15)-septate and 41–73 x 2–4 µm (McCarthy 2001). Porina meridionalis P.M.McCarthy occurs on islands in the Bass Strait and on the north coast of Tasmania; it has elongate-fusiform spores that are AUSTRALASIAN LICHENOLOGY 62, January 2008 29 often broader towards the distal end, (11–)17(–21)-septate and 41–73 x 6–9.5 µm (McCarthy 2001). A third species, P. rhaphidosperma Müll.Arg., is known from eastern and southern U.S.A.; it has filiform, 13–20-septate spores that are 100–140 x 3–5 µm (Harris 1995). These three species have perithecia that are not or scarcely overgrown by the thallus even when immature, have a well-defined, black involucrellum, a comparatively thin excipulum, and elongate-cylindrical asci with a subtruncate apex and an apical chitinoid ring that becomes more sharply defined in Congo Red. Porina kennedyensis is known only from the type locality, a coastal forest in northeastern Queensland. Other corticolous species at this site include Bulbothrix goebellii (Zenker) Hale, Cratiria lauricassiae (Fée) Marbach, Graphis streimannii A.W.Archer, Haematomma africanum (J.Steiner) C.W.Dodge, H. stevensiae R.W.Rogers, Letrouitia leprolytoides S.Y.Kondr. & Elix, Parmotrema gardneri (C.W.Dodge) Sérus., Pertusaria velata (Turner) Nyl., Phaeographis colligata (Stirt.)

(Ostropales, Graphidaceae), a widespread species in eastern Australia Armin Mangold and H. Thorsten Lumbsch Department of Botany, The Field Museum, 1400 South Lake Shore Drive, Chicago, ILLINOIS 60605, USA Klaus Kalb Lichenological Institute Neumarkt, Im Tal 12, D-92318 Neumarkt, Germany Abstract: Thelotrema rimulosum Müll. Arg. is shown to be an older available name for Hemithecium hadrosporum (A.W.Archer) A.W.Archer. Consequently, the new combination Hemithecium rimulosum (Müll.Arg.) Mangold, Lumbsch & Kalb is proposed. The species was previously believed to be restricted to north-eastern Queensland. Here it is shown to be widespread along the east coast of Queensland and north-eastern New South Wales, most specimens hidden among undetermined material of Thelotremataceae. Introduction Phaeographina hadrospora A.W.Archer was described based on material from northeastern Queensland (Archer 2001). The species is characterized by inconspicuous lirellae, the absence of secondary metabolites and large pale brown, muriform ascospores. It was regarded as rare and with a restricted distribution. Following the revised generic concept in Graphidaceae (Staiger & Kalb 1999, Kalb & Staiger 2000, Staiger 2002, Kalb et al. 2004), Archer (2005) transferred the species to Hemithecium. In a recent monograph, Archer (2006) did not cite any additional specimens. As part of our revision of Australian Thelotremataceae, we became aware of Thelotrema rimulosum, a species described from Queensland (Müller 1891). This is a Hemithecium species and represents an older available name for H. hadrosporum. Further, we found several collections referable to that species among undetermined collections of Thelotremataceae and report a significant range expansion. Material and Methods Material from the following herbaria was examined for this study: ABL, B, BRI, CANB, F, G, GZU, MEL, NSW, UPS, US, WELT, and the private herbarium of Klaus Kalb (Neumarkt). Thalli and apothecia were cut using a razor blade and a freezing microtome, and examined in water and lactophenol cotton blue. Thin-layer chromatography was carried out using solvent system B’ (Lumbsch 2002) and high-performance liquid chromatography according to Feige et al. (1993). Results and Discussion Hemithecium rimulosum (Müll.Arg.) Mangold, Lumbsch & Kalb, comb. nov. Basionym: Thelotrema rimulosum Müll.Arg., Nuov. Giorn. Bot. Ital. 23: 396 (1891).

Type: Australia, Queensland, Goodna, no date, F.R.M. Wilson s.n. (NSW 426677 – holotype!). = Thelotrema monosporum Knight ex Shirley, nom. illegit. (non T. monosporum Nyl., Ann. Sci.

Knight 36: 5, n. 126) (WELT! – lectotype, here selected). A full description is given by Archer (2001, 2006). The majority of collections examined, including the type of Hemithecium hadrosporum, have roundish or only slightly elongate ascomata, and are reminiscent of thelotremoid species. Therefore, it is not 32 AUSTRALASIAN LICHENOLOGY 62, January 2008 surprising that most material examined was misidentified as Thelotrema s.lat. The species is characterized by a corticate, rather thick, strongly fissured and mostly distinctly verruculose thallus, immersed to somewhat emergent ascomata with rather small, roundish to ±elongate pores that are often paler at the rim. The proper exciple is predominantly fused, rather thick, hyaline to greyish or brownish. The hymenium is clear, has slightly branched paraphyses, and is up to c. 300 µm high. The asci are 1-spored. The ascospores are hyaline to yellowish (brown when old), amyloid, thinwalled, eumuriform, and c. 150–250 x 35–65 µm in size. The majority of specimens lack secondary compounds as stated by Archer (2001). However, a few collections contain lichexanthone and/or an unknown substance that appears as a ±faint yellowish spot above psoromic acid on TLC plates in solvent system B’. The species is widespread from north-eastern Queensland to north-eastern New South Wales (Fig. 1). It occurs in tropical and subtropical rainforests and wet sclerophyll forests.

Elix School of Chemistry, Building 33, Australian National University, Canberra, ACT 0200, Australia e-mail: John.Elix@anu.edu.au Abstract: Cryptothecia queenslandica Elix, Dirinaria sekikaica Elix, Fellhanera tropica Elix and Protoparmelia rogersii Elix are described as new to science, and the new names Menegazzia menyamyaensis Elix and Rinodina austroleprosa Elix are proposed. The examination of various collections of lichens in preparation for a further lichen volume of the Flora of Australia has led to the identification of several undescribed species. Four such new species are described in the present paper: Cryptothecia queenslandica Elix, Dirinaria sekikaica Elix, Fellhanera tropica Elix and Protoparmelia rogersii Elix. Chemical constituents were identified by thin-layer chromatography (Elix & Ernst-Russell 1993), high performance liquid chromatography (Elix et al. 2003) and comparison with authentic samples. The New Species Cryptothecia queenslandica Elix, sp. nov. Fig. 1 Sicut Cryptothecia australasica sed acidum gyrophoricum et acidum confluenticum continente differt. Type: Australia. Queensland, Mossman-Mount Molloy road, 1 km S of Lions Lookout, 20 km N of Mount Molloy township, 16°32’05”S, 145°22’59”E, 390 m, on leaves of roadside treelet at margin of rainforest, J.A. Elix 36915, 4.viii.2006 (holotype BRI; isotype CANB). Thallus crustose, foliicolous, adnate, ecorticate, pale grey to grey or greenish grey, with scattered paler slightly raised areas, continuous, thin (to 0.1 mm thick), effuse, forming irregularly spreading patches 2–5 cm wide; prothallus very thin and narrow, byssoid, comprising radiating hyphae, whitish. Photobiont a species of Trentepohlia, cells rounded to oblong, 7–12 x 5–8 µm, solitary or a few cells aggregated. Medulla indistinct, white. Isidia present, cylindrical, simple, sparsely branched or subcoralloid, 0.1–0.3 mm long, 0.03–0.07 mm wide. Ascigerous parts and pycnidia not seen. Chemistry: Thallus K–, C+ red, KC+ red, P–, UV+ pale grey-white; containing gyrophoric acid (minor), confluentic acid (major), lecanoric acid (trace), constipatic acid (minor), and protoconstipatic acid (minor). Etymology: The specific epithet denotes the occurrence of the species in Queensland. Notes: Cryptothecia queenslandica is characterized by the adnate, grey to greenish grey thallus which reacts C+ red (gyrophoric and confluentic acids) and the presence of cylindrical isidia. Its morphology closely resembles that of C. australasica Elix, but the latter reacts C–, P+ yellow due to the presence of psoromic acid and, in part, develops an orange-red pigmented prothallus (white in C. queenslandica) (Elix 2007). Cryptothecia philippinum (Vain.) G.Thor is also similar to C. queenslandica, but lacks confluentic acid and is known from only corticolous substrata (Thor 1997). At present C. queenslandica is known from only the type locality. Associated species included Bulbothrix tabacina (Mont. & Bosch) Hale, Cryptothecia australasica Elix, C. faveomaculata Mukhija & Patw., Haematomma sorediatum R.W.Rogers, Laurera meritospora (Mont. & Bosch) Zahlbr., Parmotrema gardneri (C.W.Dodge) Hale, Pertusaria scaberula A.W.Archer, Pyxine copelandii Vain. and P. fallax (Zahlbr.) Kalb. AUSTRALASIAN LICHENOLOGY 62, January 2008 35 Dirinaria sekikaica Elix, sp. nov. Fig. 2 Sicut Dirinaria applanata sed acidum sikikaicum continente differt. Type: Australia. New South Wales, Old Macleay River estuary, Stuarts Point, 30º49’S, 153º00’E, 1 m, on Casuarina glauca in strand vegetation adjacent to mangrove swamp, J.A. Elix 21346, 18.i.1987 (holotype CANB). Thallus 5–10 cm wide, adnate to tightly adnate, pinnately to subpinnately lobate. Lobes radiating, contiguous, longitudinally plicate and rugose, flat to convex, ±concave towards the tips, 0.5–2.0 mm wide, distinctly flabellate towards the apices. Upper surface grey, bluish grey to yellow-grey or off-white, ±pruinose, sorediate, dactyls absent. Soralia laminal, hemispherical or becoming elongate, sometimes erose and crateriform, soredia farinose. Medulla white, rarely the lower medulla orange towards the apices. Lower surface black in the centre, ±brown at the margins. Apothecia rare, sessile to ±constricted at base, 0.5–1.5 mm wide; disc black, rarely sparsely grey-pruinose; thalline exciple prominent or reflexed, distinct and persistent. Epithecium dark yellow-brown, c. 10 µm thick; hymenium colourless, 75–85 µm thick; hypothecium dark brown to brown-black, 160–200 µm thick. Ascospores brown, 1septate, thick-walled, Dirinaria-type, ellipsoid, 15–22 x 6–8 µm. Pycnidia black, laminal, immersed in elevated warts. Conidia bacilliform, 3.5–5 x 0.8–1 µm. Chemistry: Cortex K+ yellow, C–, KC–, P+ yellow; medulla K–, C–, KC–, P –; containing atranorin (minor), chloroatranorin (minor), sekikaic acid (major), 4’-O-demethylsekikaic acid (minor), ramalinolic acid (trace), homosekikaic acid (trace), 3β-acetoxyhopane-1β,22-diol (minor), ±unknown terpenes (minor). Etymology. The specific epithet is derived from the presence of sekikaic acid in this species. Notes: Morphologically, D. sekikaica closely resembles D. applanata (Fée) D.D.Awasthi in that both have adnate to tightly adnate thalli with pinnately to subpinnately branched, contiguous, longitudinally plicate and rugose lobes with flabellate apices, with laminal soralia and distinctly farinose soredia. However, D. sekikaica can be distinguished by its chemistry. Whereas D. applanata contains divaricatic acid as the major medullary substance, D. sekikaica contains sekikaic acid. Previous authors (Swinscow & Krog 1978) considered this taxon a chemical race of D. applanata. At present this new species is known to occur on bark, wood and rocks in coastal and montane forests in eastern Queensland and New South Wales. Commonly associated species included Dirinaria applanata (Fée) D.D.Awasthi, Lecanora helva Stizenb., L. melacarpella Müll.Arg., Parmotrema reticulatum (Taylor) M.Choisy, Pertusaria lordhowensis A.W.Archer & Elix, P. montpittensis A.W.Archer, Pyxine cocoes (Sw.)

Asci (6–)8-spored, clavate, 45–65 x 10–18 µm. Ascospores colourless, fusiform to narrowly ellipsoid, 3–5-septate, 15–20 x 4–6 µm; not or very slightly constricted at septa. Pycnidia not seen. Chemistry. Thallus K– C–, KC– P–, UV–; containing 4,5-dichlorolichexanthone (major), zeorin (major), 4,5-dichloro-6-O-methylnorlichexanthone (minor), unknown (minor). Etymology. The specific epithet refers to the tropical habitat of this species. Notes: Fellhanera tropica is characterized by the whitish green to pale green, granulose thallus, the abundant, flesh-coloured to brown, roundish apothecia with a paler proper margin, the 4–5-septate, fusiform to narrow ellipsoid ascospores and the chemistry. The apothecia and ascospores of this new species resemble those of F. microdiscus (Vain.) Vezda, but the latter species is foliicolous rather than being lignicolous, corticolous or saxicolous, the thallus is non-granulose, the apothecia are somewhat smaller (0.15–0.3 mm vs. 0.2–0.6 mm wide), and the ascospores are 3septate (Vainio 1921). Furthermore, F. microdiscus lacks lichen substances. At present this new species is known from several localities in the Northern Territory, where it occurs on dead wood, rocks or bark in moist, monsoon vine forests.

Apothecia common, dispersed, sessile, constricted at the base, round, 0.4–2.0 mm AUSTRALASIAN LICHENOLOGY 62, January 2008 37 wide; disc dark brown, ±plane to undulating or convex, glossy, darker than the margin; thalline exciple concolorous with the thallus, persistent; excipulum poorly delimited; epithecium 5–10 µm tall, dark brown; hymenium 40–60 µm tall, colourless to brownish; hypothecium colourless to pale yellow-brown, 60–100 µm thick. Paraphyses with clavate to capitate apical cells 3–5 µm wide, with a brown cap. Ascospores ellipsoidal-fusiform, often with distinctly pointed apices, 10–13 x 4–5 µm. Pycnidia scattered, immersed, black. Conidia acicular, straight or slightly curved, 6– 11 x 0.7–1.2 µm. Chemistry: Cortex K–, C–, KC–, P–, N–; medulla K–, C–, KC+ pink, P–, UV+ bluewhite; containing alectoronic acid (major), dehydroalectoronic acid (trace), ±βalectoronic acid (trace). Etymology. The species is named in honour of the collector, the Australian botanist and lichenologist Dr Roderick W. Rogers. Notes: The growth habit, apothecial anatomy and ascospores of this species closely resemble those of Protoparmelia badia (Hoffm.) Hafellner, but P. badia can readily be distinguished by its typically darker brown upper surface, the crowded, immersed to sessile, round or subangular apothecia (dispersed, round, sessile and constricted at the base in P. rogersii) and by the chemistry. Whereas P. badia contains lobaric acid (major), oxolobaric acid (minor), conlobaric acid (trace), sublobaric acid (trace), norlobaric acid (trace), ±zeorin (minor), and ±usnic acid (minor), P. rogersii contains alectoronic acid (major), dehydroalectoronic acid (trace), and ±β-alectoronic acid (trace). Protoparmelia pulchra Diederich, Aptroot & Sérus. is chemically identical to P. rogersii, but grows on dead wood and bark rather than rocks, and has narrower ascospores (2–3 µm vs. 4–5 µm wide) that are ellipsoid and not pointed at the ends (Aptroot et al. 1997). At present this species is known from only the type collection. Associated species included Lecanora farinacea Fée, Parmotrema reticulatum (Taylor) M.Choisy and Relicina sydneyensis (Gyeln.) Hale.

McCarthy Australian Biological Resources Study, GPO Box 787, Canberra, ACT 2601, Australia Continental Australia supports a rich foliicolous lichen flora of at least 209 species, 18 of which are considered to be endemic (McCarthy 2007). In August, 2005, ahead of a field excursion to the tropical Northern Territory, it was hoped that localized but moderately diverse foliicolous communities might be found along creek banks and in sheltered gorges in monsoon vine forest where the most severe effects of winter drought might be ameliorated. However, 12 days of intensive exploration in many of the most likely habitats yielded only seven taxa usually in very sparse communities dominated by species of Strigula and including much depauperate, nondescript and sterile growth. 1. Fellhanera bouteillei (Desm.) Vezda, Folia Geobot. Phytotax. 21, 214 (1986) This cosmopolitan lichen is also known from bark and rock. In Australia, it has been reported from leaves in Queensland and Tasmania, as well as Christmas Island (McCarthy 2007). 1 2 SPECIMENS EXAMINED Northern Territory: • Howard Springs Nature Park, 38 km SE of Darwin, 12°28’03”S, 131°02’54”E, monsoon vine forest along stream, on leaves, alt. 20 m, P.M.

Elix 37693 (part), 6.viii.2005 (CANB). Discussion In Australia, foliicolous lichen diversity is greatest in the coastal and hinterland areas of eastern Queensland, which support 174 species. Eastern and south-eastern New South Wales (including the A.C.T.) has 62 species, Victoria 12 and Tasmania 27 (McCarthy 2007). Such communities thrive in the absence of the prolonged drought coupled with high temperatures which clearly play a significant role during the dry season in tropical areas of the Northern Territory. Coastal and subcoastal areas of the Northern Territory experience an alternating cycle of flood and drought. The wet season, from late October to April, is characterized by high rainfall and humidity, high temperatures and comparatively low rates of evaporation. The dry season (from late April to October) has very low or no rainfall, while high temperatures are maintained, with low to very low humidity and high evaporation rates (Bureau of Meteorology 2007). By contrast, coastal areas of northeastern Queensland experience appreciably lower temperatures and sufficient rainfall even in the dry season to maintain rich foliicolous communities. The striking disparity between foliicolous lichen diversity in the Northern Territory tropics and at low elevations in coastal areas of north-eastern Queensland is also seen among other elements of the lichen flora. Thus, while creeks, sheltered gullies and shaded rock outcrops in Queensland provide niches for 20–30 saxicolous species of Monoblastiaceae, Porinaceae, Strigulaceae and Verrucariaceae, the most suitable comparable habitats in the Northern Territory included only Porina chloroticula and the rare P. nuculastrum. Similarly, while 10–15 corticolous species of Porina occur, often in considerable abundance, along the Queensland coast, only P. eminentior and rare and usually sterile thalli of P. tetracerae were seen in coastal areas of the Northern Territory.

Louwhoff Royal Botanic Gardens Melbourne, Birdwood Avenue South Yarra, Victoria 3141, Australia Abstract: Eight species of Umbilicaria are confirmed for Australia: U. cylindrica, U. decussata, U. hirsuta, U. nylanderiana, U. polyphylla, U. subglabra, U. umbilicarioides and the first Australian record of U. cinereorufescens. Introduction The current checklist of Australian lichens lists nine species in the macrolichen genus Umbilicaria (McCarthy 2008). A recent investigation of Tasmanian collections documented six species; Umbilicaria cylindrica (L.) Delise ex Duby, U. decussata (Vill.) Zahlbr., U. nylanderiana (Zahlbr.) H.Magn., U. polyphylla (L.) Baumg., U. subglabra (Nyl.) Harm. and U. umbilicarioides (B.Stein.) Krog & Swinscow (Kantvilas & Louwhoff 2007). Two additional taxa, Umbilicaria hirsuta (Sw.) Ach. and U. cinereorufescens (Schaer.) Frey, are reported here from the Australian mainland; neither is common, and the latter is a new record for Australia. Earlier records of U. hyperborea (Ach.) Hoffm. and U. proboscidea (L.) Schrad. were based on misidentifications of U. nylanderiana. Australian species of Umbilicaria are monophyllous or polyphyllous, with a smooth, scabrid, pustulate or sharply ridged upper surface, and black apothecia that are gyrose (folded) or leiodisc (smooth). Asci usually contain eight simple spores. However, while U. cinereorufescens produces brown muriform spores, the Australian specimen was sterile. Some species produce rhizinomorphs, which while they resemble rhizines, their primary function is not attachment. The rhizinomorphs, as well as the lower surface of the thallus, can be covered with specialized vegetative diaspores called thalloconidia, creating a lumpy texture. Umbilicaria hirsuta is the only sorediate species in Australia, and isidiate species do not occur here. Gyrophoric acid is common in the genus and occurs in all but two Australian species, and it may or may not have associated umbilicaric and/or lecanoric acids. Only U. polyphylla has umbilicaric acid as the major medullary substance. This paper provides a key to the Australian species of Umbilicaria, a discussion of variation in U. cylindrica, as well as descriptions and taxonomic, ecological and distributional notes on U. cinereorufescens and U. hirsuta. Additional information relevant to mainland Umbilicaria species is also included, as well as a short discussion on some biogeographical aspects of the genus in Australasia.

U. polyphylla 7: Thallus mostly monophyllous, whitish or greyish pruinose; margins undulate to upturned; apothecial disc smooth, not gyrose.......................................U. subglabra The species Umbilicaria cinereorufescens (Schaer.) Frey, Hedwigia 71, 109 (1931) Thallus 5–12 cm diam., mostly monophyllous, with lobes entire, rigid, coriaceous, orbicular, with or without broad folds; margins entire or incised-torn. Upper surface dull, smooth to scabrous, areolate-cracked, occasionally with rhizinomorphs protruding through cracks or tears, cream-buff or pale grey to violet-grey or slate-grey, with occasional reddish staining, pruinose or not, rarely somewhat eroding. Lower surface mostly coarsely papillate-verrucose, covered with a thick matt of rhizinomorphs; umbilicus flat or slightly raised, ±trabeculate nearby, frequently with lamellae fading or extending to margins and becoming fimbriate, black with occasional dark brown margins. Rhizinomorphs of two types: dense, short, stout, black, clavate and covered in thalloconidia, interspersed with scattered, longer, cylindrical, dark brown to black structures, blackened at the base due to thalloconidia. Thalloconidia on lower surface of thallus, on surface of clavate rhizinomorphs, or at the base and tips of cylindrical rhizinomorphs; individual cells roundish 5–7(–10) µm wide, brown, thick–walled, frequently clumping together, forming clusters 17–25 µm wide. Apothecia not seen in Australian material. Hestmark (2004) reported apothecia rare, gyrose; ascospores brown, muriform, 8–15 x 4–9 µm. Pycnidia scattered, immersed, visible as black dots on the upper surface; conidia bacilliform, 3–4(–5) x 0.5–0.7 µm. Chemistry: medulla K–, C+ red, KC+ red, P–; containing gyrophoric acid (major). Umbilicaria vellea (L.) Ach. closely resembles U. cinereorufescens, and the two can be difficult to separate (Llano 1950, Krog & Swinscow 1986, Wei & Jiang 1993). That was especially true of specimens collected by Thomson from New Zealand (Wei & Jiang 1993), which were identified as U. vellea. Umbilicaria vellea has longer (2 mm cf. 1.5 mm), branched, often (pale) brown and somewhat “shaggy” rhizinomorphs that are abundant, and larger thalloconidia (23 x 28 µm cf. 17 x 25 µm in U. cinereorufescens). Unfortunately, the type of U. cinereorufescens was not available for study, and published descriptions of the species vary. Llano (1950) described the “rhizinae” [rhizinomorphs] as absent or very short, stubby and occasionally club-tipped, while Krog & Swinscow (1986) described them as short, stout and ball-tipped, with some branched, slender, black rhizinomorphs with blunt tips and short, coarse, black outgrowths. Wei & Jiang (1993) state that the “rhizines” [rhizinomorphs] are absent or very short and occasionally club-tipped but never capitate. 46 AUSTRALASIAN LICHENOLOGY 62, January 2008 Umbilicaria cinereorufescens is known from Europe, Greenland, North America (Llano 1950), Asia (Wei & Jiang 1993) and East Africa (Swinscow & Krog 1988). This new record for Australia is based on a collection from a granite overhang in alpine New South Wales.

Three varieties of U. cylindrica have been recognized for Australia (Llano 1950): Umbilicaria cylindrica var. fimbriata (Ach.) Nyl. (MEL 11061), U. cylindrica var. tornata (Ach.) Nyl. (MEL 1013295) and U. cylindrica var. delisei (Despr.) Nyl. (MEL 11046). The specimen determined as U. cylindrica var. fimbriata (Ach.) Nyl. is, in fact, a mixture of U. cylindrica and U. umbilicarioides. Umbilicaria umbilicarioides bears a strong similarity to U. cylindrica, and the two often grow side-by-side. A detailed discussion of the two taxa is provided by Kantvilas & Louwhoff (2007). Material determined as U. cylindrica var. tornata (Ach.) Nyl. typically has small, crowded, polyphyllous thalli, but these are not unusual in U. cylindrica and are within the natural variation exhibited by the species. The collection determined as U. cylindrica var. delisei (Despr.) Nyl. has a monophyllous thallus that is more robust than typical U. cylindrica specimens, and it lacks marginal rhizinomorphs. A number of other specimens from New South Wales and Victoria resemble this variety, but nevertheless they fall within the circumscription of U. cylindrica because characters often intergrade. There is no doubt that the species is very polymorphic, and the name U. cylindrica sens. str. as applied by Kantvilas & Louwhoff (2007) may still represent more than one taxon. However, this would require a worldwide re-assessment, as suggested by Kantvilas & Louwhoff (2007). The U. cylindrica complex in the broader sense would benefit from phylogenetic analyses incorporating molecular data. Umbilicaria hirsuta (Sw.) Ach., Kongl. Vetensk.-Akad. Nya Handl. 15, 97 (1794) Thallus 2–8(–14) cm diam., monophyllous or polyphyllous, orbicular, thin but rigid; umbo obscure to moderately elevated, with or without a few soft folds; margins irregularly lacerate, edges eroded, frequently reflexed dorsally. Upper surface dull, pale to dark grey or camel-brown, particularly towards margins, covered with a fine network of fissures, areolate, becoming powdery-sorediose along lobe apices; soredia fine, pale grey, coalescing to form irregular brown granules. Lower surface camelbrown to grey-brown to chestnut-brown, dark brown around the umbilicus, granularareolate, flat to folded or wrinkled, occasionally with small pits; umbilicus small to medium-sized, compact. Rhizinomorphs sparse to moderately dense, solitary or forming small tufts, concolorous with lower surface, cylindrical, simple or branched. Thalloconidia not seen. Apothecia and pycnidia not seen in Australian material. Hestmark (2004) reports apothecia rare, with narrow gyri; ascospores simple, hyaline, 10–14 x 4–8 µm. Chemistry: medulla K–, C+ red, KC+ red, P–; containing gyrophoric acid (major), lecanoric acid (minor). Umbilicaria hirsuta superficially resembles U. cinereorufescens but is readily distinguishable because the latter species is not sorediose, has characteristic short, clavate rhizinomorphs interspersed with slender, blunt-tipped structures and is trabeculate around the umbilicus. This species is known from Asia, U.S.A. and Mexico (Wei & Jiang 1993). It has not been reported from New Zealand (Galloway 2007). Rarely collected in Australia (subalpine N.S.W. and A.C.T.). AUSTRALASIAN LICHENOLOGY 62, January 2008 47 SPECIMENS EXAMINED New South Wales: • Tinderry Peak, 10 km E of Michelago, 35°41’S, 149°16’E, alt. 1618 m, on exposed subalpine granite boulder on granite ledge, J.A. Elix 362, 13.ix.1974 (CANB); Australian Capital Territory: • Mt Coree, 29 km W of Canberra, 35°18’S, 148°48’E, alt. 1400 m, under rock overhang at summit, D. McVean 65133, xii.1965 (CANB). Discussion Most Umbilicaria species in Australia occur in subalpine and alpine habitats, from c. 1400–1600 m upwards in south-eastern mainland Australia, and above c. 900 m in Tasmania. The greatest diversity is in New South Wales, where all eight species occur, followed by the Australian Capital Territory with seven, and Victoria and Tasmania with six. Umbilicaria polyphylla occurs in the Stirling Ranges, Western Australia, and the genus is absent from Queensland, the Northern Territory and South Australia. On the mainland, Umbilicaria is best represented along the Great Dividing Range, from Lake Mountain in Victoria to Mt Coree in the Australian Capital Territory. In Victoria, there are additional collections from the Grampians (1167 m altitude) in western Victoria and Mt Macedon (1011 m altitude) in central Victoria, areas that are not subalpine in a strict sense, but they do receive occasional snow. The genus extends as far north as Mt Kaputar and Ben Lomond in northern New South Wales. Both areas are at an altitude of around 1500 m and receive snowfall during winter. The southern limit of Umbilicaria in Australia is in the South West National Park in Tasmania, but it occurs throughout the central regions of the State, from Mount Field National Park to The Cradle Mountain-Lake St Clair National Park, as well as Ben Lomond National Park in the north-east. A more detailed discussion on the distribution and ecology of Umbilicaria in Tasmania is provided by Kantvilas & Louwhoff (2007). Umbilicaria species occur predominantly on hard rocks such as Ordovician to Upper Devonian granite outcrops (e.g. Mt Buffalo, Mt Bogong, Mt Baw Baw, parts of the Grampians and the Kosciuszko region), as well as on hard siliceous Upper Devonian to Lower Carboniferous sedimentary rocks (e.g. Mt Wellington and Mt Howitt). Four of the Australian Umbilicaria species occur only at high latitudes in both the Northern and Southern Hemispheres: U. hirsuta, U. subglabra, U. umbilicarioides and U. nylanderiana (Table 1). They essentially occupy similar alpine or tundra-like habitats in both hemispheres (Galloway 2007). More than half of New Zealand’s Umbilicaria species are bipolar in their distribution (Table 1). Umbilicaria hirsuta is predominantly a Northern Hemisphere species that has not been reported from elsewhere in the Southern Hemisphere. The remaining four Umbilicaria species in Australia can be regarded as cosmopolitan: U. cylindrica, U. polyphylla, U. decussata and U. cinereorufescens. Umbilicaria decussata has a widespread distribution worldwide, but it is restricted to high alpine habitats (Krog & Swinscow 1986). In Australia, it occurs on exposed, alpine windswept rocks or on sheltered rock outcrops, in exposed subalpine herbfields or alpine grasslands. It was mostly collected from alpine New South Wales (13 collections), less commonly from the Victorian Alps (three collections), and it is rare in Tasmania with only two known localities from dolerite summits (Kantvilas & Louwhoff 2007). In New Zealand it was collected from Mt Cook at 3507 m altitude, the highest exposed rocks in the country (Galloway & Sancho 2005). Table 1 lists the species of Umbilicaria confirmed for Australia and New Zealand (Galloway 2007). Seventeen of the 19 species recorded for Australasia occur in New Zealand. In addition, New Zealand has three endemic species of Umbilicaria (Table 1). There, the genus is most commonly seen in the foothill ranges east of the Main Divide in the South Island (Galloway & Sancho 2005, Galloway & Ledingham 2006, Galloway 2007). Many of the peaks along the Southern Alps are at elevations of at least 2500 m, whereas most peaks along the Great Dividing Range in Australia are below 2000 m. Thus, the alpine and subalpine habitats favoured by Umbilicaria are much more extensive in New Zealand, probably accounting for the greater diversity of Umbilicaria there. 48 AUSTRALASIAN LICHENOLOGY 62, January 2008 Acknowledgements Many thanks to Patrick McCarthy for helpful comments and advice on the manuscript.
