Bryoerythrophyllum alpigenum (Bryophyta, Pottiaceae) confirmed in the moss flora of Poland, with a review of the nomenclatural issues associated with this species name

Ryszard Ochyra — 2020-10-20

Occurrence of Bryoerythrophyllum alpigenum (Jur.) P.C.Chen in Poland is confirmed. The species is known from a single record from the Western Tatra Mountains in the Polish Western Carpathians. A description and illustrations of the Polish material of this species is provided and its distribution mapped. Taxonomic and nomenclatural comments on B. alpigenum are presented and its global geographical distribution is reviewed. This species was first recognised as a variety, Didymodon rubellus var. dentatus Schimp., in 1860 by W. P. Schimper. It was subsequently described in 1882 by J. Juratzka as Didymodon alpigenus Jur., and its name should be ascribed to Juratzka alone, not to Venturi as suggested in Index muscorum and D. alpigenus Jur. is the basionym of Bryoerythrophyllum alpigenum. The epithet alpigenus appeared in the literature for the first time as Trichostomum alpigenum Venturi in Pfeffer’s work of 1869 dealing with the mosses of the Rhaetian Alps, but the name was not validly published under Art. 36.1, because Pfeffer did not accept it. Likewise, the name Didymodon alpigenus was not validly published by Venturi ten years later under Art. 38.1, because no description or diagnosis or a reference to a previously and effectively published description or diagnosis were provided. The current statistics of the moss flora of Poland is given. Since the publication of the catalogue of Polish mosses in 2003, some 17 species, one subspecies and three varieties of moss have been added to and two species were excluded from the moss flora of Poland, so currently some 715 species, nine subspecies and 90 varieties are known to occur in the country.

New and noteworthy lichenicolous and bryophylous fungi from the Ukrainian Carpathians

Valeriy Darmostuk — 2020-12-16

Nine species, Acremonium rhabdosporum, Arthonia digitatae, Bryocentria metzgeriae, Diplolaeviopsis cf. symmictae, Skyttea gregaria, Rhymbocarpus pubescens, Stromatopogon cladoniae, Tremella cetrariicola and Xenonectriella subimperspicua, are newly reported for Ukraine. Sphinctrina anglica is recollected for the first time since 1955. Parmelia saxatilis and Parmelina pastillifera are new host species for X. subimperspicua.

Two new Bacidina species (Lecanorales, Ascomycota) from Pakistan

Maham Fatima — 2020-12-17

Bacidina margallensis and B. iqbalii from Pakistan are described and illustrated. Phylogeny of ITS nrDNA region confirms their position within the genus Bacidina, and morphological data make them distinct from other known species of the genus. Based on molecular data, corticolous Bacidina margallensis appears to be a sister species to B. chloroticula, but morphologically, when dry, is the most similar to known from Europe B. mendax because of the granular and warted greenish grey thallus, whitish-cream to dark brown and often piebald apothecia. It differs from that species by shorter, wider and less septate ascospores; 1–3-septate in B. margallensis vs 3–5(6)-septate in B. mendax, and by unusual parrot-green colour of wet thallus. Saxicolous Bacidina iqbalii is closely related to B. neosquamulosa but differs in having crustaceous thallus, transculent when wet entirely pale apothecia, larger asci and less septate large ascospores.

New records of lichens and lichenicolous fungi from Murmansk Region, Russia

Gennadii Urbanavichus — 2021-03-30

As a contribution to the lichen flora of the Murmansk Region, eight taxa of lichens and lichenicolous fungi collected from the biogeographic province Kuusamo, are reported for the first time, including two species new to Russia: Roselliniella nephromatis and Scytinium aquale. Arthonia granitophila is new to European Russia, and Sclerophora amabilis – for North European Russia. Comments on habitats, substrates, key anatomical features and distribution of new records are provided.

Emilia A. Ossowska — 2021-05-06

The first records of Parmelia barrenoae from Hungary, Slovakia and Sweden and P. pinnatifida from Denmark, Estonia and Turkey are presented.

Noteworthy lichenicolous fungi and lichens from Russia

Mikhail P. Zhurbenko — 2021-05-25

Notes are presented on seven species of lichenicolous, non-lichenized and lichenized fungi found in the Asian part of Russia. Endococcus pseudocarpus is reported for the first time for Northern Asia as well as for the Irkutsk Region of Russia. Plectocarpon hypogymniae and P. nephromeum are reported new to the Irkutsk Region, Taeniolella diploschistis new to the Republic of Sakha (Yakutia), Steinia geophana new to Chukotka Autonomous Area, and Epigloea soleiformis new to the north of the Krasnoyarsk Territory of Russia. Hypogymnia physodes is reported as a new host species for Plectocarpon hypogymniae.
