    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 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
