Type studies of Polyporaceae (Aphyllophorales) described by J. Rick. - Nord. J. Bot. 7: 553-568. Copenhagen. ISSN 0107-055X. The type species of Polyporaceae (Aphyllophorales) and of other related genera, i.e. Irpex, Grammothele and Theleporus, described by J. Rick were studied. Of the 938 names of species or varieties 34 are invalidly published and 21 are synonyms. Nineteen type specimens were not found and 4 were sterile. Four species were respectively assigned to Datronia, Steccherinum, Trechispora and a cyphellaceous fungus, and were left without specific determination. The following new combinations are proposed: Aporpium substuppeus, Ceriporiopsis latemarginata, Inonotus micantissimus, Junghuhnia polycystidijera, Perenniporia piperis, Phanerochaete furfuraceo-velutinus, Skeletocutis roseolus and Tvromyces atro-albus. Two new species are described: Ceriporiopsis lowei and Gloeodontia americana. M .

Introduction zyxwvutsr The Austrian-born jesuit Johann Rick described a large number of polypores, most of them collected in the environments of Ssio Leopoldo and SBo Salvador (Rio Grande do Sul State, Brazil) where he held a professorship in theology and undertook his mycological research. In order to obtain a comprehensive notion on the polypore flora of Southern America it was deemed advisable to carry out a study of Rick’s type collections most of which are extant at the Herbarium Anchieta, Sio Leopoldo (PACA). During a three day visit to that herbarium the author was able to revise these collections. A proper selection of types and other specimens was later studied in the author’s laboratory. The study also included those specimens assigned to Irpex Fr. and other genera related to the Polyporaceae. A few type collections kept in other herbaria were also investigated. After Rick’s death in 1946, B. Rambo arranged his herbarium and published Rick’s monograph on the Rio Grande d o Sul fungi which appeared in Iheringia Bot. no. 2 , 4 . 5 , 7 . 8 . and 9 between 1958 and 1961; un0 fortunately, he failed to update the nomenclature or typify many names. The fungi are listed alphabetically according to the generic and specific epithets followed by a reference to where they were published. Specimens are cited with their present PACA’s number as Fungi Rickiani no. (FR). followed by the place and date of collection and any indication, if present, of it being the type. General locality of most specimens, i.e. Brazil, Rio Grande d o Sul State, is neglected unless of different origin, and so are the ‘legavit’ and ‘determinavit’ notes which always correspond to Rick. Other notes on the original label are also quoted to aid tracing the specimens studied. No other indications, such as Rick’s notes on the specimens’ features and/or descriptions are added unless necessary for justifying lectotypification. When lectotypes are designated the following formula is employed: ‘selected lectotype’. Specimens of previously published Rick’s new species, cited afterwards (Rick 1959, 1960) as types are here considered as lectotypified by him.

Even if they are validly published such specimens correspond with those cited by Lloyd for his species. Measurements and drawings were made from freehand sections mounted in 1% aqueous phloxine solution in 5% KOH solution. Color notations were made in accordance with Maerz and Paul (1930). All herbarium abbreviations are as given by Holmgren and Keuken (1974). (Fig. 2); some may present incrustations. They are IKI-, acyanophilous, and give a positive metachromatic reaction in cresyl blue. Basidia claviform, 15-16x4-5 pm (Fig. 3). Spores widely ellipsoid to subglobose, 3 . 5 4 ~ 2 . 5 - 3pm, exhibiting 1-2 guttulae in the cytoplasm, I K I t , acyanophilous, numerous (Fig. 4). Associated with a white rot. zyxwvutsrq zyxwvutsr zyxwvu zyxwvutsrq Daedalea latemarginata Rick (1960: 263) Holotype FR 20230, S.

Fruitbody orbicular and resupinate, later fusing and with reflexed margins, up to 7x6X0.2 cm, loosely attached to the substratum, contracting when dry; white when fresh, straw to light cinnamon when dry; light, but rigid when dry. Margin distinct, wide, slightly lobate. Hymenial surface at first merulioid, developing pores, teeth or ridges; pores 1.5-2 per mm, varying from round typical ones to daedaloid and also irpicoid. Context up to 0.4 mm thick, tubes up to 1.5 mm long, both concolorous with the pore surface. Hyphal system monomitic. Generative hyphae with clamp connections, 2.5-5 pm diam., with thin but distinct hyaline walls in the subhymenium and the dissepiments (Fig. 1) and with thickened ones in the context and a few in the dissepirnents; the latter with few clamps and may be confused with skeletal hyphae Figs 1 4 .

Fig. 4, spores. 554 Remarks: the species is distinct by its small, broad, ellipsoid spores, wide pores, irregular hymenial configuration and generative hyphae with thickened walls. C. mucida (Pers.: Fr.) Gilbn. & Ryv. is different because of its smaller pores and spores and the lack of generative hyphae with thickened walls (cf. Domaliski 1972). I have been unable to find any similar species among those described in Poria Pers. and Tyromyces Karst. (Lowe 1966,1975). A small specimen of this fungus was gathered recently in Argentina (BAFC 30428, Buenos Aires, Campana, INTA Delta, leg. M. Rajchenberg and J. E. Wright 3858, 16.1V.85). Daedalea unicolor Bull.: Fr. var. ochracea Rick (1937~:160) Selected lectotype FR 15630, sub Daedalea ochracea Kalchbr., Sudafrika, leg. Witz: “Africa do Sud, Missao do Boromos, leg. Eng. Witz, 111-1909”. = Datronia Donk sp. Fruitbody effused-reflexed, 7X2X0.2 cm, sessile, annual. Pileus tomentose, zonated with dark buff and black zones. Context chestnut with a black line under the tomentum. Pores 2.5-3 per mm, round to somewhat elongated. Hyphal system dimitic with clamped, thin-walled generative hyphae, 2 4 pm diam., and light chestnut skeletal hyphae 2-S(7) pm diam. with walls up to 1.5 pm, mostly with a visible lumen. Spores cylindric, hyaline, 9-12-(13)~4-5 pm, IKI+, acyanophilous. Remarks: though Rick (1937~)presumably had Daedalea ochracea Kalchbr. in mind as he stated in the original envelope, formally he validated a new variety for Daedalea unicolor Bull.: Fr. (= Cerrena unicolor (Bull.: Fr.) Murr.). D. ochracea is a synonym of Polyporus meyenii fide Ryvarden (Ryvarden & Johansen 1980). Though the sample is a large one, it is somewhat eaten by insects either in the upper surface or the hymenophore. Nevertheless, the spore and hymenial features are clearly discernible and key out in the genus Datronia. The specimen is different from the known species of this genus on account of the pore and spore size. D . mollis (Somf.: Fr.) Donk exhibits larger, angular pores 1-2 per mm, a white lower context and smaller spores, 7.5-1OX2.54 pm. D . stereoides (Fr.) Ryv. has smaller pores, 4-5 per mm and the fruitbody is rarely reflexed. zy Nord. I. Bot. 7 ( 5 ) 1987 zyxwvu not indicated in the protologue.

Rick (1960) refers this collection from Brazil, Taquaremb6, 1935, but no indication of this was found in the PACA’s envelope or on the original label, which only bears the specimen’s name, presumably written by Rick himself. This specimen is scant and weathered and a correct determination could not be made. I also studied the specimens cited by Rick (1960) other than the type: FR 15786, Taquaremb6, 1935: “In ligno frondoso, no. 1733, Poria suberis?”, and FR 15792: “In ligno frondoso, no. 1725”. Both are Phellinus contiguus (Pers.: Fr.) Pat. FR 15792 also contains a manuscript description of the fungus, probably written by Rick himself, which is identical with that published. Nevertheless, as Rick formally designated FR 15866 as the holotype of the species, no legal argumentation concerning Rick’s intentions can be sustained.

Irpex amhiguus Peck var. barbiformis Rick (1959 188) Not validly published since the nomenclatural type was not indicated in the protologue. I found all the specimens cited by Rick (1959) but none of them had any indication of the varietal name. Specimens FR 16611 and 19613, both sub Irpex ambiguus Peck, Marcelino Ramos, 1935, were studied. They represent specimens close to Metulodontia nivea (Karst.) Parm. differing in their odontioid hymenophore (not grandinoid as in European specimens), narrower ellipsoid spores, 4X 2-2.5 pm and undetected gloeocystidia.

Bat. 7 ( 5 ) 1987 The sample is small, 3 ~ 0 . 7cm and represents a resupinate fungus with elongated pores. The hyphal system is typical of the species but has a very good development of the skeletal hyphae; generative hyphae are slightly thick-walled and typically hyphodontioid. Spores are 555 Fruitbody resupinate, adnate, 8 . 5 ~ 2 . 5cm, irpicoid, grandinoid between the aculei; margin indeterminate. Aculei up to 1.3 mm long, irregularly scattered, more or less solitary, 2-3 per mm, crowded, up to 5 per mm, inclined with regards to the substrate, more or less ceraceous in consistency, covered by a pruina. Context up to 0.5 mm thick. Hymenial surface with a gossypine aspect, cinnamon or toast (MP 13F8). Hyphal system monomitic. Generative hyphae 2.54.5 pm diarn. with (generally) thickened melleous walls, with a clamp at each septa or simple-septate. Toward the substratum hyphae exhibit both kinds of septa (Fig. 5), but in the subhymenium and hymenium they are mostly clamped and so are the basidia and basidioles (Fig. 6). Sometimes hyphae widen up to 7 pm. In the subhymenium hyphae are short-celled. Mature basidia not seen. Basidioles cylindric to claviform, 7-12x45 pm, clamped at the base. Spores ellipsoid, with a flattened side, 4.5-5.5xs3.5 pm, hyaline, thin-walled, IKI+ , acyanophilous (Fig. 7). Cystidia cylindric, slightly clavate or with a slightly tapering apex, 30-lW190~5-9 pm, clamped at the base, with thickened walls in the middle portion, with a homogeneous content (Fig. 8). Associated with a white wood-rot. Remarks: it is with some reluctance that the species is included in Phanerochaefe Karst. as in this genus basidial septa and subhymenial hyphae are devoid of clamps, which are mostly restrained to the subicular hyphae. Nevertheless, hyphae are thick-walled and with a melleous colour, and cystidial and spore shape are characteristic of many species of the genus. This species is distinct on account of the irpicoid hymenium and its peculiar hyphal system and does not fit any of those recorded by Burdsall (1985) for the genus. Eriksson et al. (1978) have stated that “possibly there may exist fibulate species, which in other respects are so close to Phanerochaete that they must be included, but so far we don’t know of such species”. P.furfuraceo-velufinus fits very well into this picture; only the occurrence of other similar species will allow us to decide whether they ought to be placed in a different genus. zyxwvutsrqpo zyxwvu zyxwvutsrqpon zyxwvut zyx zyxwv zyxw Figs 5-8. lrpex furfuraceo-velutinus (from holotype FR 16597). - Fig. 5 , generative hyphae from the subiculum with simple septae and clamps. - Fig. 6, generative hyphae from the subhymenium and basidioles exhibiting a clamp at each septa.

It differs from typical specimens by the thick dissepiments, the lack of cystidioles, the lack of incrustations on the hyphae and cystidioles (as observed in subtropical specimens), and the presence of cubic/ rhomboid/amorphous crystal aggregations, 20-25 pm wide, along the dissepiments.

Maas Geesteranus (1974) transferred the species to Steccherinurn S. F.

Steccherinum subochraceum, as suggested by the ICBN Recommendation 72A. For a description see Maas Geesteranus (1974) and Hjortstam and Bononi (1986).

Salvador, 1943: “18.IV.1943”. = Steccherinum S . F. Gray sp. Macromorphologically the hymenophore of this specimen resembles that of S. cremeoulbum Hjortstam (1984), presenting short aculei with fimbriated tips that vary from grandinoid to odontioid, but differs in being easily detachable from the substratum (actually the original envelope only contains the fungus with no substratum attached to it) and by presenting a mycelial margin with rhizomorphs. Microscopically it differs in its clamped generative hyphae and its cylindric spores 3 . 5 - 4 . 5 ~1.5-2 pm. Cystidia are only present at the tips of the aculei. S. fimbriatum (Pers.: Fr.) J. Erikss., to which the species may also be related, has been reported from the same type locality (Hjortstam & Ryvarden 1982). However, S. fimbriatum is a more dark ochraceous species with a tough consistency and with ellipsoid spores, 3.2-3.5-(4) X (2)-2.2-2.5 pm. Probably this represents a valid species but more material should be studied before making a decision in this sense. Irpex palmatus (Berk.)

Gloeocystidia cylindric, claviform or fusiform, with or without a round papilla at the apex, 2045x5-7 pm, with abundant granular oily contents, giving a strong positive reaction in sulphobenzaldehyde; they may project up to 12 pm beyond the hymenium (Fig. 14). Large masses of irregular crystals are also seen in the aculei. 1c Fig. 15. Irpex subhypogaeus (from lectotype FR 16631), spo- res. with a poroid configuration could not be confirmed. Spores in this specimen are ovoid ellipsoid, echinulate, with slightly thickened walls, 5-6X3.5-4 pm, with warts 0.5-(1) pm long (Fig. 15). Hyphal system is monomitic with clamped generative hyphae, 1.5-3 pm diam., which may present swollen portions up to 5 pm wide. The species is different from other hydnoid species described in the genus (Jiilich 1976) on account of its larger spores. Other specimens cited by Rick (1959) and gathered after the publication date were not studied but might help to better understand this species. Irpex tomentoso-cinctusRick (1959 190) Not validly published since the nomenclatural type was not indicated in the protologue. The two specimens cited by Rick were studied: FR 16613, Sta.

Spores are subglobose, 5 x 4 pm. Typical acuminate cystidia were very few. zyxwvut Remarks: the species is distinct in the genus on account of its larger spores and the lack of pseudo- or skeletocystidia. Hydnum pyramidatum Berk. & Curt., from Cuba, which probably belongs in Gloeodontia Boidin differs in its monomitic hyphal system, its smaller spores, 5 4 x 6 5 pm, and the uncertain presence of gloeocystidia (cf.

Rick (1932) described a fungus with “. ..dentibus primitus porosis deinde laceris compressis.. .”. Unfortunately, although the principal microscopical features are well preserved, macroscopically it is quite difficult to confirm Rick’s observations as all the material is badly broken and only small fragments are available for study. In the larger fragments teeth up to 1.3 mm long could be seen but they are mostly crowded and their relationship 558 Polyporus atro-albus Rick (1935b: 25) Selected lectotype FR 18397, sub Polyporus albo-ater, Porto Novo, 1932, typus: “In ligno frondoso, no. 1402”. = Sromyces atro-albus (Rick) Rajchenberg comb. nov. (basionym: Polyporus atro-albus Rick (1935b: 25)). Though kept under a different name, FR 18397 is certainly the type collection as it fits very well the original description. This is a previous name for Trametes humeana Murrill (1939) (NY, type studied, USA, Florida, Gainesville, leg. W. A. Murrill). See Lowe (1975) for a description. Polyporus atro-marginatus Rick (1940b: 286) Not validly published since no latin diagnosis was given.

No specimen was found at PACA under this name. Rick (1960) did not include the name in his monograph on Southern Brazil polypores. Polyporus cartilaginosus Rick (1935b: 22) The name was first published ‘ad interim’ by Rick (1907); according to the ICBN Art. 34.l(b) this should not be considered a valid publication. Later, Rick (1928) mentioned the species and stated the type to come from Sfio Leopoldo, but did not point out at which herbarium it was kept. Thus Rick (1935b) is considered the date of valid publication. Rick (1960) cited specimen FR 20417 which was not found at PACA but FR 20470 with similar data: Tupandi, IX.1945, leg. and det. Rick: “Pol. cartilaginosus Rick ?, nullus typus exitit, solum av est photographia”, “Intus zonalis albus tenue brunascens. Pol. cartilaginosus Rick?”, “Polyporus fusco-mutans Lloyd?, Natal, Sept. 1945”. The three separate labels clearly suggest that FR 20470 is not the type, which is presumably lost. The specimen is sterile and undeterminable. Hyphal system is trimitic looking very much like that of Polyporuspalustris Berk. & Curt. No specimen under this name was available either from Herb. Lloyd (BPI) or from FH. A collection was found, FR 19778, sub Poria foetens Rick, S.

P. cartilaginosus Rick). It is also an illegitimate name as it is preoccupied by Polyporus farinosus Bref. (Brefeld 1889) for which reason Saccardo and Traverso (1911) gave it a new name, viz. Polyporus rickianus Sacc. & Trav., which was validated the following year (Saccardo & Trotter 1912). Lloyd (1915) validly published the name, but it is a nom. illegit. for the above given reason. Rick (1928) made reference to the species in Rick (1907) and Lloyd (1915) and stated the type was in Lloyd’s Herbarium. Such material, BPI Herb. Lloyd no. 13309, Brazil, leg. J. Rick: “odor farinae”, represents the specimen of the photograph in Rick’s original description (Rick 1907, p. 85, Tab.

Bot. 7 ( 5 ) 1987 559 zyxwvutsrq zyx zyxwv Fruitbody lignicolous, annual, dimidiate, light, Pilei imbricate, up to 3X2.5X1 cm each, strongly convexed downwards, juxtaposing the tubes with the pileal surface of the lower fruitbody, leaving the hymenophore mostly hidden except relatively small portions that keep growing; the pileal surface appears then with a nodular aspect as if it were sterile mycelium (Fig. 16). The exposed pilei are small and surrounded by a distinct margin, which is more evident in the lower portion. Pileal surface matted-tomentose to somewhat hispid, azonate, cinnamon in the portions with the exposed hymenophore, rusty-brown and glabrous in the others. Context up to 0.5 cm thick, cinnamon, with the upper portion soft, substuppeous and becoming firmer downwards; some fruitbodies exhibit a discontinuous resinous zone in the lower context. Tubes up to 0.5 cm long, dissepiments cinnamon but hymenial surface with a grayish tint, light woody in consistency. Pores 1-2 per mm, angular. Hyphal system dimitic. Generative hyphae with rather scant clamp connections, some typically of the hammer type (Fig. 17), 2-4 pm diam. with hyaline to melleous, slightly thickened walls. Skeletal hyphae only present in the lower context and in the dissepiments, 3.5-5 W r n in diam. with thickened, melleous to light chestnut walls, not branched, mostly with a distinctiumen (Fig. 18). Basidla inflated and ovoid, with four longitudinal crosswalls, 8.5-11X6.5-8 pm, epibasidia up to 6 pm long, with many oily contents (Fig. 19). Spores ellipsoid, hyaline, thin-walled, 6 - 8 ~ 4 4 . 5 pm, repetitive, with oily contents, IKI- (Fig. 20). - Remarks: Polyporus gregarius was invalidly published by Rick (1940b) because a latin diagnosis was not given. Later (Rick 1960) he validated the name by providing a latin diagnosis, a reference to the original description and by citing the type, which is the only specimen extant at PACA. The note that the tvoe comes from Vila Paperi must certainly be an error as neither in the PACA’s envelope nor in the original label that locality is mentimed.. The general description, consistency, colour, pileal features and hyphal system in P. gregarius were found to come close to Polyporus substuppeus Berk. & Curt. (cf. Lowe 1975. Ryvarden 1984). The holotype of this species was studied (K, Brazil trail no. 123) and the following features were ‘similar to those present in P. gregarius: nature of the pileal surface, consistency, . pres. ence of a resinous zone in the lower context; hyphal systcm with presence of hammer like clamps in the generative hyphae (Fig. 21) and melleous to chestnut skeletal hyphae. and in similar shaoe of spores with abundant or& contents (Fig. 22) whiih are sbmewhat smaller, 57 x 4 4 3 pm. P. substuppeus is different in the general morphology of the fruitbody, which is not strongly convex but only slightly so. in the pore size, 2-4 per mm, and in the cartilaginous consistency of the tubes. Unfortunately. mature basidia could not be seen with cer- tainty but only clavate basidioles which are scant in a mostly collapsed hymenium. Nevertheless, all other vegetative features are identical with those of P. gregarius for which reason the new combination in Aporpium Bond. & Sing. is proposed. The particular morphology of P. gregarius seems atypic and should not b e given much importance. Polyporus subreflexus Lloyd (1919) from the Philippine 11s. and its synonym Polyporus hiascens Lloyd (1922) from S.

Bot 7 ( 5 ) 1Y87 zyxwvutsrqp bambusicola Rick, “In Tagnaro, S. Leopoldo, Rio Grande do Sul, 1933, det. Rick”. This has the same features as FR 18570 but its spores exhibit a more distinct dextrinoid reaction. I am of the opinion that FR 18570 pertains to a species close to Phellinuspunctatus but it is not the same due to the presence of setae. Lowe (1966) pointed them to be “usually absent, or scattered and scarcely projecting” but they failed to be found in the numerous specimens at BAFC coming from the NE provinces of Argentina and Southern Brazil. David et al. (1982) recently described P. pseudopunctatus, similar to P. punctatus, differing by exhibiting subventricose setae 15-30x9-10 pm, different cultural features and a smaller amount of styryl-pyrones. A more detailed study of the numerous names and their types proposed for P. punctatus, and summarized by Lowe (1966) should be made to better understand the species complex around this species. Wright and Deschamps (in Wright & Blumenfeld 1984) incorrectly changed the name of the species to Phellinus rickianus assuming the combination in Phellinus was preoccupied by Phellinus bambusarurn (Pat.) Pat. This is not the case, as the correct epithet published by Patouillard (1900) is Phellinus bambusinus (Pat.) Pat., based on Polyporus bambusinus Patouillard (1891). Under the name Phellinus rickianus Wright & Desch., Wright et al. (in press) have described a fungus gathered in the Argentine NE subtropical province of Misiones which does not fit the lectotype of Poria bambusarum Rick. It presents a resupinate-pulvinate habit of growth with a distinct sterile margin, and microscopically is distinguished on account of its hooked setae and its globose dextrinoid spores. This species has been described as new in a different paper (Rajchenberg 1987). Poria chrysoloma Fr. var. hambusae Rick (1960: 278) The holotype cited by Rick, i.e. FR 17570, was not found at PACA.

Bourd. & Galz. zyxwvut zyxwv Lowe (1963) had already indicated a relationship with this species. Later (Lowe 1966) he pointed out a relationship with Fomitiporia punctatiformis Murr. (NY, holotype studied: USA, Florida, Cocoa, leg. Rhoads F-12073, 10.VI. 1937) which exhibits smaller pores 6-7 per mm, smaller hymenial setae 18-23x5-7 pm and cylindric spores with tapering ends 5-6-(7)X2-2.5 pm. Poria cinnamomea has pores 4-5 per mm, setae 253 0 x 6 7 pm and cylindric spores with no tapering ends, 67x2-2.5 pm. I think it fits better with the concept of Phellinus ferreus, though somewhat differing because of its chocolate brown pore surface. zyxwvutsrq Poria cinnamomea Rick var. dupla Rick (1960: 289) Not validly published since the nomenclatural type was not indicated in the protologue.

Poria hyalina Berk. var. macrospora Rick (1960: 271) Not validly published since the nomenclatural type was not designated in the protologue. Two cited specimens were studied: FR 18624, S.

Not validly published since the nomenclatural type was not indicated in the protologue. A specimen was found among those cited by Rick under the type variety, viz. FR 18783 sub Poria membranicincta Berk., S. Leopoldo, 1939: “var. megalospora Rick, Nov. 1939”, which is perhaps the specimen on which the variety was described. This is Schizopora paradoxa (Schrad. : Fr.) Donk. Poria micantissima Rick (1960: 287) Holotype FR 20691, S. Salvador, 111. 1944: “In Nectandru mortua”. = Znonotus micantissimus (Rick) Rajchenberg comb. nov. (basionym: Poria micantissima Rick (1960: 287)). Fruitbody annual, resupinate, 10X4X 1.4 cm; margin regular, light fulvous. Hymenial surface dark sienna to gray chestnut. Pores round, 5-7 per mm. Tubes oblique, up to 1.4 cm long. Context almost absent, tubes dark fulvous. Consistency woody hard. General aspect of a Phellinus QueI. species but lighter in weight. Hyphal system monomitic. Generative hyphae with simple septa, 3-5 pm diam., with yellowish to chestnut, zyxwvutsrqponm 36 Nord. J . Bot. 7 ( 5 ) 1987 565 slightly thickened walls. Setal hyphae abundant in the dissepiments, 160-300-(400) pm long, 10-15 pm wide but swelling up to 25 pm in 5% KOH sol., with dark chestnut walls up to 4 pm thick, tapering towards the ends, not protruding into the pores or rarely so (Fig. 35). Hymenial setae lanceolate with a ventricose base, 20-32x5-9 pm, scant and in some sections totally absent, apparently found only in the young pores and in the pore mouths (Fig. 36). Basidia and basidioles present but partially collapsed and measurements are not representative. Spores (?) globose to subglobose, 10-13x8-12 pm, apiculate, with slightly thickened walls, hyaline to slightly melleous, with abundant oily contents, IKI+, acyanophilous (Fig. 37). Poria ramentacea Lkrk. 8z Br. var. epipolyporeaRick (1937b 149) Selected lectotype FR 18668, sub Poria ramentacea, Pareci, 1936: “In polyporo gilvo, sp. 2x2.5 pm, no. 1694“. Though no indication of the varietal name was made neither on the PACA’s envelope nor on the original label, this is certainly the material on which the variety was described, as it grew on Polyporus gilvus Schw. and the size of the spores indicated in the label is the same as published by Rick. = Schizopora paradoxa (Schrad.: Fr.) Donk. Spores were not found and the hymenium is mostly collapsed but the hyphal system and pore size strongly suggest this species. zyxwvu zyxwvutsrqp zyxwvu Remarks: the species comes quite close to Inonotus pegleri Ryvarden (1975), described from East Africa, which differs in its larger pores 4-5 per mm, smaller spores 6-7 pm diam., and setae that may reach 32 pm wide. It is similar on account of its general macromorphology (massiveness and Phellinus aspect), the long setal hyphae, the shape of spores and the very few hymenial setae present (Ryvarden & Johansen 1980). The spores in I. micantissimus are of somewhat doubtful origin: they are not typical in shape for Inonotus species and exhibit conspicuous oily contents. The latter feature recalls chlamydospores and Rick (1960) described them also as concatenated. But I failed to find them as such and they were only present in the tubes and not in the trama and/or context. Their regular shape and dimensions would point to them being true basidiospores but I failed to find them attached to basidia. Rick related the species to Phellinus weirii (Murr.) Gilbn., but it differs in its dimitic hyphal system, protruding setal hyphae and smaller ovoid thin-walled hyaline spores ( 5 . 5 ~ 4 . 5pm). Poria subcanescens Rick (1960: 286) Holotype FR 18545, sub Poria argilacea Cke., S. Leopoldo, 1933: “In ligno frondoso, no. 1613”. = Phellinus ferreus (Pers.) Bourd. & Galz. zyxwvuts Poria subfusco-flavida Rost. var. tenuissima Rick (1960: 282) Not validly published since the nomenclatural type was not indicated in the protologue. The specimen cited by Rick (1960) under the type variety, i.e. FR 18594 was labelled with the new varietal name on the PACA’s envelope and in the original label: FR 18594, S. Leopoldo, 1939: “Juni 1939, no. 1096”: = a very poorly developed specimen of Phellinus ferreus (Pers.) Bourd. & Galz. zyxwvutsr zyxwvutsr Poria subhexagonoidesRick (1937b: 133) No specimen under this name was found at PACA, nor was later cited by Rick (1960). Poria polycystidiferaRick (1960: 281) Poria subviridis Rick (1937b: 151) Holotype FR 22630, S. Salvador, 1944: “5.1V.1944, typus”. = Junghuhnia polycystidifera (Rick) Rajchenberg comb. nov. (basionym: Poria pofycystidifera Rick (1960: 281)). This is a previous name for Junghuhnia microspora Rajchenberg (1983). See there for a description. Lectotype FR 18583, S.

Poria pulchella Schw. var. subpulchella Rick (1960: 280) Not validly published since the nomenclatural type was not indicated in the protologue. No specimen under this variety name was found among Poria pulchella Schw. collections at PACA. 566 A small resupinate sample of the species. As it may be assumed from the label on the original envelope, Rick probably described this specimen twice, first as Grandinia arachnoidea (Rick 1932) and later as Poria subviridis. This is perhaps the type for Grandinia arachnoidea which Hjortstam and Ryvarden (1982) could not study. Nord. J .

Leopoldo, typus: “In ligno frondoso, no. 1591”. = Diplomitoporus lenis (Karst.) Gilbn. & Ryv. Not validly published since the nomenclatural type was not indicated in the protologue. A specimen was found among those cited by Rick (1960) for the type variety o n which, presumably, the variety was described: FR 19296, sub Trametes isabellina Fr. var. azurea Rick, S. Leopoldo, 1932: “In ligiio frondoso” and with a latin diagnosis similar t o that published by Rambo. It is a sterile and indeterminable poroid resupinate fungus. FR 18596, which was cited by Lowe (1963) as a synonym of Trechispora regularis (Murr.) Liberta, is probably the same collection he later cited as lectotype (Lowe 1966). Since it has no indication in Rick’s handwriting that it is a “typus”, such as is the case with FR 18685, this material cannot be considered the lectotype of P. subvulgaris. Poria tenui-sulphurea Rick (1960: 284) Not validly published since the nomenclatural type was not indicated in the protologue. A specimen was found that is, presumably, the collection o n which the species was described: FR 20341, sub Poria?, S. Salvador, 1943: “Poria tenui-sulphurea Rick n. sp., 21 .VII.1943”. This is Ceriporia viridans (Berk. & Br.) Donk. Poria velata Rick (1937b: 148) Selected lectotype FR 18747, Pareci, 1930: “In ligno frondoso, sp. sphaericis 5 ym”. = Ceriporia xylostromatoides (Berk.) Ryv. Lowe (1963) studied FR 18513 which later was presumably referred by him as the lectotype (Lowe 1966). This collection contains no fungus at PACA, but a label was found which states: “In ligno frondoso, Sta. Maria, 1936; sp. 3 ~ 2 . ym, 5 asperis, Rick”. T h e measurements of the spores are not in accordance with those given in the protologue (“sp. sphaericis, albis, 5 pm”, cf. Rick 1937b) as is the case of FR 18747 label. Therefore, FR 18513 cannot be considered the proper lectotype of P. velata. Another collection was studied, viz. FR 18527, Sta. Maria, 1936: “In ligno frondoso, no. 1658, sp. 3x2.15 ym”: = Trechispora regularis (Murr.) Liberta. Poria vestita Rick (1960: 288) Holotype FR 18490, Sta.
