The lichens of Pukhtolova Gora (St. Petersburg, Russia)

The lichen diversity of the proposed protected area Pukhtolova Gora counts 252 species, including 232 lichenized, 12 lichenicolous, and 8 non-lichenized saprobic fungi. Micarea laeta, M. pusilla, and Pyrenidium actinellum s. lat. are new to North-Western European Russia; Parmelia serrana, Rhizocarpon cinereovirens, and Stereocaulon taeniarum are new to St. Petersburg. Altogether 13 species recorded in the study area are red-listed in St. Petersburg, with two of them known only from historical collections. Pukhtolova Gora is an area with a high conservation value; the lichen biota of this area is one of the richest within the city limits due to the well-preserved forest habitats

New records of lichens and allied fungi from the Leningrad Region, Russia. XIII. Mainly saxicolous species

Arthopyrenia cinereopruinosa, Aspicilia grisea, Buellia miriquidica, Catillaria atomarioides, Lithocalla ecorticata, Miriquidica intrudens, Rhizocarpon intermediellum, Sclerococcum amygdalariae, and S. parasiticum are new for North-Western European Russia

New and rare lichens and allied fungi from the Novgorod Region, Russia

44 species of lichen-forming, lichenicolous and non-lichenized fungi are reported from the Novgorod Region, 34 of them are new to the region. Leptogium biatorinum is new to European Russia. Nephromopsis laureri is red-listed in Russian Federation and should be included in the Red Data Book of the Novgorod Region. Most noteworthy records are briefly discussed. Two species – Collema callopismum and Hertelidea botryosa – are excluded from the lichen list of the Novgorod Region

New records of lichens and allied fungi from the Leningrad Region, Russia. XI

Twelve lichen species and two lichenicolous fungi, of them seven that belong to Micarea prasina group, are reported for the first time for St. Petersburg or the whole Leningrad Region. The lichenicolous fungus Intralichen baccisporus is new to Russia, and the lichen Micarea nowakii – for European Russia. A comparative table of characteristics for seven species of Micarea prasina group is presented

Leprarioid lichens and associated lichenicolous fungi from the Commander Islands (Kamchatka Territory, Russia) including a new species Lepraria tiinae

Here, we present new records of leprarioid lichens from the Commander Islands, including one species of Lithocalla and six species of Lepraria. Notably, we describe as new to science Lepraria tiinae, which is quite common in coastal biotopes of the archipelago. The main distinguishing phenotypic features of this new species include large granules of the thallus, a well-developed hypothallus, dark rhizohyphae, and the production of thiophanic acid, arthothelin, and dichlorolichexanthone. Additionally, three species of lichenicolous fungi or fungi associated with leprarioid lichens were found in the studied specimens, all of which are new to the Kamchatka Territory

Three new species of crustose Teloschistaceae in Siberia and the Far East

Three species of the family Teloschistaceae (lichenized Ascomycota) are described as new to science from Southern and Eastern Siberia and the Far East. Corticolous Caloplaca saviczii belongs to the genus Caloplaca s. str.; it has C. cerina-like apothecia and green to grey-green, crateriform soralia with a white rim. Lendemeriella aureopruinosa is a saxicolous taxon with a thin grey thallus and small apothecia 0.3-0.6 mm in diameter, with a dark orange disc usually bearing epipsamma and often with a grey true exciple containing the pigment Cinereorufa-green. Orientophila infirma is a corticolous species with an endophloeodal thallus and small orange apothecia, 0.2-0.3 mm in diameter, usually with an inconspicuous thalline exciple. All new taxa presumably have a boreal north-eastern distribution in Asia

Ninety-one species of lichens and allied fungi new to Latvia with a list of additional records from Kurzeme

The results of lichenological excursions of the 19th Symposium of Baltic Mycologists and Lichenologists (BMLS) in Latvia, Kurzeme region, 22–26 September 2014, are reported. A list of 290 species is presented, of which 238 are lichenized, 43 lichen-inhabiting, and nine saprotrophic fungi: ninety-one species are new to Latvia, twelve of which (Caloplaca duplicata, Cresporhaphis wienkampii, Ellisembia lichenicola, Gallowayella weberi, Gregorella humida, Lichenochora weillii, Parmelia serrana, Polycauliona phlogina, Reconditella physconiarum, Stictis brunnescens, Thelocarpon superellum, and Verrucaria tectorum) are also new for the Baltic States. Athallia alnetorum is reported here for the first time in northern Europe. The presence of Ochrolechia androgyna s. str., Athallia holocarpa and A. pyracea is confirmed for Latvia, and Parmelia submontana is reported as a new host for Homostegia piggotii
