Revised descriptions with new images and records of the European species Acarospora nitrophila and A. praeruptorum are published. Acarospora moraviae is treated as synonym of A. nitrophila. Acarospora matraensis, incorrectly reported as A. nitrophila, is described from Hungary.
Based on the collections of Koryak geobotanical expeditions of the Komarov Botanical Institute, 21 species of lichens and lichenicolous fungi are reported as new to Koryakia: 13 of them are also new to Kamchatka; Arthonia granitophila, A. peltigerea, and Protoparmelia ochrococca are new to the Russian Far East; Fuscidea lowensis and Polycoccum microcarpum are new to Russia. Altogether 550 species of lichens and allied fungi are currently known for Koryakia.
On November 21, Andres Saag, the long-serving Editor-in-Chief of Folia Cryptogamica Estonica, celebrated his 70th birthday.
Herewith, we continue to upgrade the Estonian checklist of lichenized, lichenicolous and allied fungi, and report 14 fungal species new for Estonia, nine of them lichenized (Absconditella pauxilla, Aquacidia trachona, Arthonia helvola, A. reniformis, Lecidea fuliginosa, Lempholemma chalazanum, Lepraria membranacea, Phaeophyscia hirsuta and Trapelia elacista), and four lichenicolous (Bryostigma phaeophyciae, Endococcus verrucosus, Everniicola flexispora and Tetramelas pulverulentus), while Melaspilea bagliettoana is doubtfully lichenized. In addition, four species (Fuscidea cyathoides, Ophioparma ventosa, Rhizocarpon oederi and Sphaerophorus globosus) have been rediscovered, and the presence of one species, Physcia dimidiata, previously known from the literature (Mereschkowski,1913) has been confirmed based on herbarium material. Physcia magnussonii is excluded from the checklist of Estonian lichens.
Altogether, here are listed 172 fungal species from Tartu based on the field notebooks of the first author and dried fruit bodies in the fungarium of the Estonian University of Life Sciences (acronym TAAM). The list mostly includes common Estonian species, among which two are nature-protected species (Caloboletus radicans and Leucocoprinus nympharum) and three are deadly poisonous species (Amanita phalloides, Inosperma erubescens, and Lepiota brunneoincarnata).
