The lichens of forest rocky communities of the hill Muroigora (Arkhangelsk Region, Northwest Russia)

The present study reports 188 species and 2 subspecies of lichens and allied fungi from forest rocky communities of the hill Muroigora situated in the Arkhangelsk part of the National park “Vodlozersky” (Arkhangelsk Region, NW Russia). Lepraria ecorticata is new to Russia, and 13 more species are new for the mainland area of the Arkhangelsk Region: Arthonia mediella, Arthonia vinosa, Bacidia igniarii, Bryoria vrangiana, Chaenothecopsis pusiola, Cladonia caespiticia, Lecidea plana, Lepraria borealis, Micarea misella, Pertusaria pustulata, Schaereria cinereorufa, Xanthoparmelia pulla and Xylographa trunciseda. Two lichen species, Bryoria fremontii and Lobaria pulmonaria, are in the Red Data Books of the Arkhangelsk Region and Russian Federation. A total of 89 species are reported as new for the Vodlozersky National Park.

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

Three lichen species and eight lichenicolous fungi were recorded for the first time for St. Petersburg or Eastern Leningrad Region. In addition, the protected species Lobaria scrobiculata was rediscovered in the Leningrad Region. The lichenicolous fungus Arthonia parietinaria is new to Russia, and two species, Didymocyrtis melanelixiae and Tremella everniae, are new for European Russia

Konevets Island (Leningrad Region, Russia) – a historical refuge of lichen diversity in Lake Ladoga

We present an updated checklist for Konevets Island (Leningrad Region, Russia). The revealed lichen biota comprises 435 species, including 378 lichens, 46 lichenicolous fungi and 11 non-lichenized saprobic fungi, of which 31 species (27 lichens and 4 lichenicolous fungi) are known only from collections made by Veli Räsänen (1917, 1938). Acremonium hypholomatis is reported for the first time for Russia; Caloplaca soralifera, Trapelia corticola, and Muellerella lichenicola for Northwestern European Russia; and Bacidia vermifera, Lecanora mughicola, Micarea contexta, Pyrenochaeta xanthoriae, Rhizocarpon disporum, Stigmidium squamariae and Xylographa difformis for Leningrad Region. From lichenological point of view, the most valuable habitats of Konevets Island are old-growth spruce forests. The studied lichen biota is rich and diverse and exceptionally well-preserved in comparison to the mainland part of Karelian Isthmus. It definitely deserves protection

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

Forty-one species of lichens and two lichenicolous fungi are reported from the Pskov Region. Of them, thirty-nine species are new for the region, including Lempholemma dispansum – a rare species with scattered distribution, previously recorded only once in the European Russia in the 19th century. The most important findings are confined to ancient limestone outcrops and old manor parks: these habitats are also promising for further investigations, taking in account high level of anthropogenic transformation of the Pskov Region

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

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
