Lichenicolous fungi from the Kamchatka Peninsula, Russia

Abstract Fifty-one species of lichenicolous fungi are reported from Kamchatka, all but three being new to the area. Epinephroma gen. nov., Endococcus peltigericola sp. nov. (on Peltigera membranacea), Epinephroma kamchatica sp. nov. (on Nephroma parile) and Stigmidium buelliae sp. nov. (on Buellia disciformis) are described as new to science. Phoma lobariicola is new to Asia and Russia, Epicladonia stenospora, Plectocarpon peltigerae, Sphaerellothecium propinquellum and Tremella cetrariicola are new to Asia, Zwackhiomyces sphinctrinoides is new to Russia.

Lith., 18(2): 85-100. The paper reports the results of lichenological investigations in Asveja Regional Park (eastern Lithuania). A large part of the study was performed during the joint 18th Symposium of the Baltic Mycologists and Lichenologists (BMLS) and Nordic Lichen Society (Nordisk Lichenologisk Förening, NLF) meeting on 19-23 September 2011. A list of 259 species is presented. Of these, 30 species are new to Lithuania. Arthonia helvola, Bacidina sulphurella, Candelariella lutella, Catillaria croatica, Cladonia conista, Gyalecta derivata, Lecanoraquercicola, Leptosphaeria ramalinae, Strigula jamesii, Trichonectria rubefaciens, Verrucaria banatica, V. boblensis, V. christiansenii, V. illinoisensis, V. inornata, V. nigrofusca, V. trabicola, Zwackhiomyces diederichii were recorded for the first time in the Baltic countries. New lichens to Lithuania are as follows: Bacidiaincompta, Caloplaca crenulatella, C. pyracea, Catinaria atropurpurea, Lecanora populicola, L. semipallida, Mycobilimbia epixanthoides, Ramalina dilacerata, Verrucaria inaspecta, and new lichenicolous fungi are: Cladosporium licheniphilum, Stigmidium microspilum, Xenonectriella leptalea. Eighteen species included in the Lithuanian Red Data Book were recorded, which is the highest number known for any studied area in Lithuania.

Lichen Diversity on Carbonate Stone Substrates in St. Petersburg, Russia: A Review

The review of published records of lichens on carbonate stone substrates (marbles, limestones, limestone tufa, and concrete) in Saint Petersburg has been presented. Altogether, 66 species of lichens from 35 genera and 16 families have been found in more than 40 papers. The most diverse genera are Verrucaria, Physcia, and Lecanora. Most of the species inhabiting carbonate stone materials in Saint Petersburg form episubstratic thalli, only the species of genus Verrucaria, often have endolithic or mostly endolithic thalli and could cause pitting of carbonate materials. Other lichen inhabitants of these substrates could be agents of substrate piling. The majority of taxa were not reported in Saint Petersburg from natural carbonate materials (marbles, limestones, or limestone tufa), but only from concrete; species inhabiting exclusively carbonate stones in Saint Petersburg are very few; lichens strictly confined to natural carbonate substrates are almost absent.
