Habitat patches of green shield-moss (Buxbaumia viridis) host diverse set of bryophytes and lichens of conservation concern: case study from hemiboreal Estonia

Piret Lõhmus — 2025-05-16

Green shield-moss Buxbaumia viridis is an epixylic forest bryophyte threatened in several European countries. In Estonia, the species belongs to the strictest protection category since 2004 and therefore, around each species localities the habitat patch is delineated and excluded from any logging activity. The aim of the current study was to survey do habitat patches of B. viridis entail other species of conservation concern (SPEC) and if they do, to evaluate specificity of such additional protection value. Standardised stand-scale survey of bryophytes and lichens in 12 habitat patches of B. viridis revealed in total 60 SPEC species (37 lichen and 23 bryophytes). Woodland indicator species and/or dead-wood specialists dominated among SPEC bryophytes and red-listed epiphytic species among SPEC lichens, but legally protected bryophytes and lichens were scarce. Comparison with the dataset collected with the same survey protocol from 12 forest sites not inhabited by B. viridis (but being potentially suitable habitats for the species in terms of forest site type and age) showed lower total SPEC richness (48 species) but no significant difference on mean SPEC number per plot. However, lichens SPEC composition differed between site groups. This indicates, that at least in European hemiboreal region, where clear-felling based forestry is prevailing, logging-free zone around all localities of B. viridis can provide simultaneous protection for diverse set of SPEC bryophytes and lichens, which are often inconspicuous and legally not strictly protected at the national level. In the current study also the presence of gemmae of B. viridis was confirmed for the first time in Estonia.

The lichenicolous genus Biatoropsis (Tremellales, Basidiomycota) in Belarus

Iryna Bolsun — 2025-06-20

Seventeen specimens of lichenicolous fungi of the genus Biatoropsis were found during the revision of 538 herbarium collections of the lichen genus Usnea in Belarus. Two Biatoropsis species were identified, Biatoropsis rubicundae (on Usnea ceratina) and B. usnearum (on U. florida, U. intermedia and U. subfloridana). Biatoropsis rubicundae is reported here as new to Belarus. Based on the studied material, morphological descriptions, ecological preferences and distribution data for the identified species are provided.

Eseniya A. Timofeeva — 2025-08-22

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.

New and noteworthy records of lichenized, lichenicolous and allied fungi from Estonia

Liis Marmor-Ohtla — 2025-11-14

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.

A list of fungi in Tartu City (Estonia): Agaricales, Boletales, and Russulales

Kuulo Kalamees — 2025-11-14

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).
