Three species of Coccocarpia have been reported from Korean Peninsular. However, there was no revisional study on this genus before. After careful examination of the specimens deposited in the Korean Lichen Research Institute (KoLRI) and collected from main mountain areas of Korea, two species of Coccocarpia, C. palmicola and C. erythroxyli, have b...
In northeastern Poland, the chemical variation of the Cladonia chlorophaea-pyxidata group was much neglected, as TLC has not been used in delimitation of species differing in the chemistry. As a great part of herbal material of University in Bialystok from NE Poland was misidentified, I found my studies to be necessary. Based on the collection of 1...
The genus Phaeophyscia Moberg, which belongs to the family Physciaceae, includes about 50 species, with 17 species reported in South Korea. This genus is characterized by a foliose thallus, Physcia/Pachysporaria-type ascospores, a paraplectenchymatous-type lower cortex, and lacking atranorin. In this study, about 650 specimens of Phaeophyscia align...

Brackel, W. v. & Wirth, V. 2023. Lichenicolous fungi from the natural region Black Forest (SW Germany). – Herzogia 36: 84 –130. Lichenicolous fungi known from the natural region Black Forest are listed, mainly based on recent finds. On the whole, 197 taxa are mentioned, including 183 described obligately lichenicolous fungi. Lichenosticta wirthii (on Loxospora cismonica) and Tremella altimontana (on Caloplaca cerina) are described as new to science. Further 17 species are new to Germany: Carbonea aggregantula, Clypeococcum cladonema, Didymocyrtis melanelixiae, Endococcus sardous, Lichenostigma rupicolae, Minutophoma chrysophthalmae, Neobarya peltigerae, Polycoccum versisporum, Rhymbocarpus neglectus, Roselliniopsis groedensis, Sclerococcum pertusariicola, Sphaerellothecium araneosum, S. stereocaulorum, Stigmidium leprariae, Taeniolella chrysothricis, Tremella tuckerae, Trimmatostroma vandenboomii and Weddellomyces turcicus. Another 42 species are new to Baden-Württemberg. Putative new species from the genera Endococcus, Lichenochora, Lichenothelia, Muellerella, Phaeoseptoria, Sphaerellothecium, Stigmidium and Trimmatostroma are sketched but not formally described. The distribution, rarity and endangerment of lichenicolous fungi and the possibility to evaluate these factors are discussed.
... Similar 4-spored asci also occur in C. crozalsiana (H.Olivier) Nav.-Ros., Cl.Roux & Casares and C. stenotropae Nav.-Ros. & Hafellner, that can be distinguished by the asci and ascospore size (Navarro-Rosines et al. 1995;Calatayud et al. 2013). Cercidospora macrospora is considered a holarctic taxon (Hafellner 1987), and this is the first record for the western sector of the Italian Alps (Brackel 2016 A couple of slender, small-sized and mycenoid basidiomata referable to the genus Conocybe Fayod (due to the campanulate and ochraceous-yellowish pilei, exannulate stipe, and rust-brown spore print) was detected in the grassy litter at the edge of a poplar stand. ...

We present a checklist for Moshchny Island (Leningrad Region, Russia). The documented lichen biota comprises 349 species, including 313 lichens, 30 lichenicolous fungi and 6 non-lichenized saprobic fungi. Endococcus exerrans and Lichenopeltella coppinsii are reported for the first time for Russia; Cercidospora stenotropae, Erythricium aurantiacum, Flavoplaca limonia, Lecidea haerjedalica, and Myriospora myochroa for European Russia; Flavoplaca oasis, Intralichen christiansenii, Nesolechia fusca, and Myriolecis zosterae for North-Western European Russia; and Arthrorhaphis aeruginosa, Calogaya pusilla, and Lecidea auriculata subsp. auriculata are new for Leningrad Region. The studied lichen biota is moderately rich and diverse, but a long history of human activity likely caused its transformation, especially the degradation of forest lichen biota. The most valuable habitats for lichens in Moshchny Island are seashore and dune communities which definitely deserve protection.
