BRYOPHYTES
Errata corrige. Paludella squarrosa (Hedw.) Brid. (Meesiaceae), erroneously reported
as new for Trentino-Alto Adige in Ravera et al. (2017), is confirmed to occur in this
region, but new only for the mentioned site.
Diplophyllum obtusifolium (Hook.) Dumort. (Scapaniaceae)
+ FRV: Alta Carnia, (Udine), on moist soil, (UTM WGS84 33T 359573.5156682),
ca. 1632 m, 19 October 2014, F. Sguazzin, L. Boemo, A. Boemo (Bryophytorum Herbarium F. Sguazzin). – Species confirmed for the flora of Friuli Venezia Giulia.
Diplophyllum obtusifolium is a montane-arctic-circumpolar liverwort species (Dierßen 2001). It was found together with Sphagnum palustre L., a surprising finding
because usually it is a pioneer species colonizing soils banks and track sides (Lockhart
et al. 2012). According to Aleffi et al. (2008), the presence in Italy of D. obtusifolium
is restricted to a number of northern localities with the only exception of Abruzzo.
Its occurrence in Lazio and Marche has not been confirmed over the last 50 years.
The herbarium specimen collected by Rossetti and kept in the Herbarium of the University of Pisa (PI) for Toscana (leg. Rossetti, August 1891, Forno Volasco, Apuan
Alps) actually refers to Diplophyllum obtusatum (R.M.Schust.) R.M.Schust. (Aleffi et
al. 2008). After 114 years since the first report of the species, the present finding is a
confirmation for Friuli Venezia Giulia (Bizzozzero 1885, Loitlesberger 1905, Glowacki
1908). This species seems rare in the Mediterranean basin, being recorded only for
Notulae to the Italian flora of algae, bryophytes, fungi and lichens: 5

Bosnia-Herzegovina, Bulgaria, Serbia, Spain, France, and Italy (Ros et al. 2007). It was
reported from Portugal by Ros et al. (2007), based on a record taken from phytosociological relevés from the Serra da Estrela. After a revision of the material, this record
was correctly re-attributed to Diplophyllum taxifolium (Wahlenb.) Dumort. (Ellis et al.
2012). With reference to its global distribution, D. obtusifolium occurs throughout the
western part of North America, and is also widespread in Asia, Europe, and eastern
North America. According to Hodgetts (2015), it is considered Endangered (EN) in
Hungary and Netherlands, Near Threatened (NT) in Luxemburg, Ireland and Italy,
Vulnerable (VU) in Germany.

Ptychostomum subneodamense (Kindberg) J.R.Spence (Bryaceae)
+ TAA: Kirchbergtal, south of Santa Gertrude (Bolzano) on the right bank of the
Kirchbergbach, among the stones and the low vegetation of the stream (UTM WGS84
32T 643004.5147513), 1735 m, 27 June 2017, F. Sguazzin (Bryophytorum Herbarium F. Sguazzin). – Species confirmed for the flora of Trentino-Alto Adige.
The old name Bryum subneodamense Kindb., which was recorded for Italy by Cortini
Pedrotti (2001), was considered a synonym of Ptychostomum pseudotriquetrum (Hedw.)
J.R.Spence & H.P.Ramsay by Ros et al. (2013), but later Spence (2013 and in FNA
2014) claimed that P. subneodamense is a distinct species. Ptychostomum subneodamense
is a temperate-arctic-circumpolar species; in Europe, it is regionally threatened (Dierβen
2001). Formerly, this species was known only for Valle d’Aosta (Vaccari 1913, sub Bryum neodamense Itzigs. var. ovatum Lindb. & Arr.), Veneto (Venturi 1899, sub Bryum neodamense Itzigs. var. ovatum Lindb.) and Trentino-Alto Adige (Geheeb 1883, sub Bryum
ovatum Jur.; Venturi 1899, sub Bryum neodamense Itzigs. var. ovatum Lindb.). Moreover,
Holyoak and Hedenäs (2006) mention a herbarium specimen of Bryum subneodamense
Kindberg collected nearby Gorizia (Friuli Venezia Giulia) by Loitlesberger (March 1903,
S) and reviewed by Podpĕra (1942). Therefore, our record represents the confirmation of
the occurrence in Italy of this rare species after 115 years from its last report.

This species is recognizable for its spatuliform, petaliform to flabelliform (fanshaped) basidiome, for its little raised anastomatized and spaced veins, for the short
and lateral stipe and for the flexible and wavy margin. Arrhenia spathulata grows on
soil with P. squarrosa or other mosses. It was known so far from Piemonte (Pollini
1824), Trentino-Alto Adige (Marisa et al. 1986), Toscana (Barluzzi et al. 1996, Perini
et al. 1999), Marche (Maletti 2016), Lazio (Granito and Lunghini 2011), Campania
(Violante et al. 2002), Sicilia (Signorello and Napoli 1994, Lantieri 2006, Lantieri et
al. 2009), Lombardia, Veneto, Emilia-Romagna, and Puglia (Onofri et al. 2005).

Gymnosporangium clavariiforme (Wulfen) DC. (Pucciniaceae)
+ CAL: Piano di Novacco, Saracena (Cosenza), on twigs of Juniperus communis L.

No. 69). – Species new species for the flora of Calabria.
This species is a heteroecious rust, growing on Juniperus as primary host. During
spring, it produces a set of orange tentacle-like spore tubes (tetial stage) with a jellylike consistency when wet. The secondary host is Crataegus, where G. clavariiforme
produces yellowish depressions on the leaves (spermogonial and aecial stage). The
species is widespread in Austria, Belgium, Dalmatia, Finland, Germany, Great Britain,
and Hungary (De Toni 1888). In Italy, it has been recorded from Val d’Aosta (Traverso
1912), Trentino-Alto Adige (Hellrigl 2010), and Friuli Venezia Giulia (Tomasi 2014).

Sporidesmium bacidiicola Alstrup (Sporidesmiaceae)
+ SIC: Monte Egitto, Bronte (Catania), western slope of the Etna, in an ancient Quercus congesta forest, on bark, parasitic on Physcia tenella (Scop.) DC. (UTM WGS84:
33S 493690.4179961), 1550 m, 6 October 2017, leg. D. Cataldo, det. W. v. Brackel
(Herb. Brackel 7990). – Species new for the flora of Italy (Sicilia).
The genus Sporidesmium consists of fungi with a mycelium lacking hyphopodia,
brown macronematous conidiophores and solitary, euseptate, brown to subhyaline
conidia, developing terminally and holoblastic. Most of the species are saprotrophic
or parasites of vascular plants and fungi. Only two species are lichenicolous: Sporidesmium lichenicola Iturr., D.Hawksw. & J.L.Crane, living on Leptogium (Iturriaga et
al. 2008), and S. bacidiicola, described from Denmark on Bacidia rubella (Hoffm.)
A.Massal. (Alstrup 1991). Later, it was found growing also on Fellhaneropsis vezdae
(Coppins & P.James) Sérus. & Coppins and on Physcia adscendens H.Olivier and was
known until now only from Denmark, Poland, and Germany (Alstrup and Olech
1996, Czyžewska and Kukwa 2009, Alstrup et al. 2013, von Brackel 2014). This species is characterized by effuse colonies, an immersed mycelium, erect, brown, septate,

LICHENS
Arthonia granosa B. de Lesd. (Arthoniaceae)
+ CAM: Centola (Salerno), on Quercus suber L. (UTM WGS84: 32T 526512.4434694),
290 m, 25 February 2011, G. Brunialti, V. Genovesi, S. Ravera. – Species new for the
flora of Campania.
It is a rare Mediterranean-Atlantic species, doubtfully lichenized, often collected
on cork oak (e.g., Fos 1998, Ravera 2002, Rizzi et al. 2011, Boutabia et al. 2015). It
is a characteristic lichen of the Arthonietum granosae Giralt & Gómez-Bolea 1987, an
epiphytic community restricted to coastal stations with humid maritime winds. Arthonia granosa can be distinguished from other superficially similar Arthonia species by
the white pruina on the round to oblong apothecia, hymenium I+ wine coloured and
1-septate guttulate spores 18–30 × 8–13 µm. In Italy, the species has been reported
from Lazio, Sardegna, Puglia (Nimis 2016) and Sicilia (Ottonello et al. 2011). Due to
its rarity, it is included in the Italian red list of epiphytic lichens under the “Vulnerable”
category (Nascimbene et al. 2013).

R. Benesperi. – Species confirmed for the flora of Toscana.
Coenogonium luteum is a crustose pantropical lichen with orange to pink apothecia
and green thallus. Its distribution includes both hemispheres; in Italy, it is a mostly
Tyrrhenian species (Nimis 2016). It occurs in shaded situations and, due to its rarity,
it is included in the Italian red list of epiphytic lichens under the “Least Concern” category (Nascimbene et al. 2013).

It is a species of the F. citrina-complex, characterised by large soredia/blastidia, a
limonia-type of soralium, a pale yellow thallus, and a thick apothecial margin often
covered by blastidia. Flavoplaca limonia is found on calcareous rocks or on base-rich,
hard, siliceous cliffs in dry and in sun-exposed to shaded and damp situations, but also
on twigs of maritime shrubs or on soil, below the montane belt. This species, described
from calcareous cliffs along the coast of the Island of Marettimo, Sicilia (Nimis et al.
1994), proved to be quite widespread in southern Europe (see, e.g., Vondrák et al. 2009).
Its hitherto known Italian distribution was limited to coastal localities of Puglia, Sicilia,
and Sardegna, and an inland locality in Veneto (Nimis 2016), but the species is certainly
more widespread, since in the past it was generally identified as “Caloplaca citrina”.

Gyalolechia fulgida is a Mediterranean species found mainly on calcareous rocks in
the Mediterranean belt (Nimis 2016). It was previously known for northern Italy only
in one site in Liguria (Valcuvia Passadore et al. 2000). The three new sites recorded
here, extending the Italian range of the species to Piemonte and Lombardia, are actually very close, being located on two mountainsides with the thermo-xeric character
of a mountain placed along the boundary between Val Curone (Alessandria) and Val
Staffora (Pavia). In these sites, G. fulgida was found together with the lichens Placidium
sp., Squamarina cartilaginea (With.) P.James, Squamarina stella-petraea Poelt and with
the moss Grimmia sp., in more or less sheltered concavities of sandstone outcrops,
both on the thin soil layer over weathered sandstone and on the very rock.

(TSB No. 47500). – Species new for the flora of Campania.
This is a pantropical-pantemperate species with a Mediterranean-Atlantic distribution in Europe, found on twigs of trees and shrubs in undisturbed Mediterranean

maquis vegetation along the coasts, which can be easily distinguished from all other
Parmotrema-species occurring in Italy by the white lower surface. It is a characteristic
lichen of a rare and endangered epiphytic community, which is most frequent on undisturbed, coastal sand dunes, the Parmotremetum reticulati-hypoleucini Nimis & Schiavon (1986). Its distribution in Italy is predominantly Tyrrhenian, the species having
been reported from Toscana, Lazio, Sardegna, Puglia, Basilicata and Calabria (Nimis
2016). The species is generally very rare and is, therefore, included in the Italian red
list of epiphytic lichens as “Near-threatened” (Nascimbene et al. 2013). It is certainly
declining, due to increasing touristic exploitation of coastal environments. The new
record fills a gap in its distribution along the Tyrrhenian coasts of the Italian Peninsula.

Peltigera monticola is a terricolous species, first described by Vitikainen (Vitikainen
1994), belonging to the large Peltigera canina group, a species complex that includes
taxa that are sometimes difficult to identify (Miadlikowska et al. 2003) and, for this
reason, often misunderstood. It is considered rare in Italy, where it has been reported
for the Eastern Alps and Sardinia (Nimis 2016). The records reported here are the first
for the Italian Western Alps. The first record from Piemonte is available through a herbarium specimen collected by Luigi Micheletti near Oropa and previously identified
as Peltigera canina (L.) Willd.

Pterygiopsis affinis is the only species of the genus Pterygiopsis known to occur in Italy.
The genus is part of the family Lichinaceae, which includes several genera, with varied
morphology and different photobionts. Some genera are particularly difficult to identify,
and their taxonomic position is debatable. Pterygiopsis affinis is a crustose lichen with a
placodioid, effigurate thallus, from bluish black to dark grey. Apothecia are lecanorine,
with proper margin and red disc. Asci are multi-spored, with hyaline, sub-globose to
broadly ellipsoid ascospores, ca. 6–12 × 3–6 µm. The photobiont is a chroococcoid,
unicellular cyanobacterium (Gloeocapsa), with a yellowish mucilaginous cell envelope.
Pterygiopsis affinis is a rare epilithic lichen, tolerating high solar radiation and prolonged
drought. It grows on south-exposed rocks, often along seepage tracks. In Italy, P. affinis
occurs from the Alpine regions to Puglia and Sardegna, but owing to lack of knowledge
in several Regions (Nimis 2016), its frequency has been certainly underestimated.

2016, G. Gheza (Herb. Gheza). – Species new for the flora of Lombardia.
Squamarina stella-petraea is a Mediterranean species found mainly on calcareous
rocks in the Mediterranean belt (Nimis 2016). It can be quite easily distinguished
from other saxicolous Squamarina because of its rosulate white thallus, areolate in the
middle and lobed at the margin. It was previously known for northern Italy only in
one site in Piemonte (Nimis 2016) and one in Liguria (Valcuvia Passadore et al. 2000).
The two new sites recorded here, extending to Lombardia the Italian range of the
species, are located on two mountainsides of Monte Vallassa with thermo-xeric character. Here, S. stella-petraea was found together with Squamarina cartilaginea (With.)
P.James, Romjularia lurida (Ach.) Timdal, and Gyalolechia fulgida (Nyl.) Søchting, Frödén & Arup in more or less sheltered concavities of sandstone outcrops. It was found
with well-developed rosulate thalli, but also coalesced with S. cartilaginea.

Tornabea scutellifera is a fruticose epiphytic macrolichen strictly associated with
semiarid and warm situations with frequent periods of high air humidity (Nimis and
Tretiach 1997). It is included in the Italian red list of epiphytic lichens under the “Least
Concern” category (Nascimbene et al. 2013). There are no recent records in the literature for Toscana (Micheli 1729; Savi 1825; Baglietto 1871; Saccardo 1894).

Waynea giraltiae was recently described from Portugal; it was known until now
only from the Iberian Peninsula (Portugal and Spain), growing in the lowland on the
bark of Quercus rotundifolia Lam. (van den Boom 2010). This species is characterized
by a squamulose to granulose thallus with thick-walled, hyaline, septate hairs, a welldefined upper cortex, marginate, greyish to blackish apothecia, asci Bacidia-type and
hyaline, fusiform, (1–)3-septate ascospores, 12–18 × 2–2.5 µm. Sterile specimens may
be mistaken for Agonimia opuntiella (Buschardt & Poelt) Vězda, but this species lacks
the thick hyaline upper cortex, the hairs are composed of several hyphae and the upper
surface is papillate. Sterile Physconia servitii (Nádv.) Poelt has a similar appearance, but
also in this species, the hairs are composed of several strands of hyphae and the thallus
is whitish-grey instead of greenish.
