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.
