Abstract
The genus Tylophoron Nyl. ex Stizenb. and species Tylophoron hibernicum (D. Hawksw.) Ertz et al. are reported for the first time from Russia, based on the materials collected in the North-Western Caucasus from the Krasnodar region, where its grows on Quercus pubescens in oak and oriental hornbeam forest, in Utrish Reserve, Abrau Peninsula. The genus Tylophoron is widely distributed in the tropics and subtropics, and only one pantropic species T. hibernicum is extending into the temperate latitudes in oceanic parts of the Western Europe (Ireland, United Kingdom, Belgium, France, Spain). Earlier, the genus was referred to the order Caliciales, and only recently molecular data have shown that the genus belongs to the Arthoniaceae. Species T. hibernicum is easily recognized by its pale yellowish sporodochia, 0.2–0.6(–1) mm diam., growing on felty, pale greyish to creamy or bluish thallus (containing lecanoric acid, C+red), and hyaline, 0–1-septate conidia – simple conidia ellipsoid to oblong, rarely spherical, (4.5–)6–6.5(–8) × 3–4 μm and 1-septate conidia often distinctly constricted at the septum, (6–)7–11.5(–15) × (3–)3.5–4.5(–5) μm.

В процессе изучения лишайников уникальных для России природных комплексов заповедника «Утриш», расположенного на п-ве Абрау, Краснодарский край, впервые в сентябре 2015 г. нами был собран необычный вид, представленный многочисленными полусферическими, бледно-желтоватыми спородохиями, содержащими бесцветные, простые или двухклеточные конидии

Summary
В процессе изучения лишайников уникальных для России природных комплексов заповедника «Утриш», расположенного на п-ве Абрау, Краснодарский край, впервые в сентябре 2015 г. нами был собран необычный вид, представленный многочисленными полусферическими, бледно-желтоватыми спородохиями, содержащими бесцветные, простые или двухклеточные конидии. Tylophoron hibernicum (Arthoniaceae, lichenized Ascomycota) – первое указание рода и вида для России Et al.) Ertz et al, впервые приводится для России из Северо-Западного Кавказа из Краснодарского края, из сборов авторов в дубово-грабинниковом лесу с древесины дуба пушистого (Quercus pubescens) на п-ве Абрау с территории заповедника «Утриш».
