A molecular phylogeny based on ITS1/ITS2 and mtSSU DNA sequences is presented for lichen-forming fungi in Protoparmeliopsis and its distant relative Sedelnikovaea gen. nov. The positions of the two genera in the phylogenetic tree of the families Lecanoraceae and Lecideaceae are discussed. The new combination Sedelnikovaea baicalensis (≡ Lecanora baicalensis) is proposed. The unique Sedelnikovaea-type ascus is described and illustrated. Sedelnikovaea baicalensis and Zwackhiomyces zarei are for the first time recorded from China.
A total of 158 species of lichens, three lichenicolous and three non-lichenized saprobic fungi were identified in 27 old manor parks in Minsk region, Belarus. The number of lichen species per a manor park ranged from 28 to 76 species. Lichenized fungi were collected on eight substrate types, the highest number of epiphytic lichens (77 species) were found on Tilia cordata. Eight lichen species (Agonimia allobata, Anisomeridium polypori, Arthonia arthonioides, Biatoridium monasteriense, Psoroglaena dictyospora, Reichlingia leopoldii, Sclerop-hora farinacea, Sclerophora peronella) were reported for the first time from Belarus.
As a result of the survey of lichen biota in 11 manor parks situated in the central part of the Minsk Region, 115 species were identified. Lecania erysibe (Ach.) Mudd, L. sylvestris (Arnold) Arnold and Xanthoria ulophyllodes Rasanen were recorded for the first time for Belarus. Altogether 19 species of rare in Belarus were found in the parks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
