Abstract

Collemopsidium kostikovii Khodos. & Darmostuk sp. nov. (Collemopsidales, Xanthopyrenaceae) is described as a new for science species of algicolous fungi. The new species is characterized by pseudothecia fully immersed in algal crust, (80–)90–170(–200) µm wide, not widening ostiole, 10–20 µm diam., 8-spored asci and 1-septate hyaline ascospores, (14.8–)16–19.6(–23) × (6.3–)6.4–7.8(–9.0) µm. It is morphologically similar to C. iocarpum, but differs by its not widening ostiole and association with terricolous cyanobacterial crust with dominant Nostoc muscorum.

Keywords: Nostoc, Pyrenocollema, saline soil, Poltava Region
