Verrucaria moravica Servit, Stud. Bot. Cech . 9: 95, 1948

Type.

[Czech Republic,] Moravia, Kopřivnice, Piskovnice, 490 m alt., 1922, Suza (PRM-760594!, syntype).

Description.

Prothallus not seen. Thallus whitish-grey with abundant medium greenish-brown punctae, endolithic, a dark line between contiguous conspecific thalli. Perithecia 0.23-0.35 mm, 3/4-1-immersed, leaving deep pits in the rock, surrounded by a thalline collar; ca. 40-60 perithecia/cm2. Involucrellum apical. Exciple ca. 0.26 mm in diam., wall brown. Ascospores 0-septate, 20-25 × 9-12 mm.

Notes.

Perithecia are mostly over-mature. One perithecium was sectioned. V. moravica may be rather similar to V. subtilis, but differs in the presence of dark lines between contiguous conspecific thalli. In the original description, the spore length was reported to be more variable: 18-28 × 9-12 ( Servít 1948). In V. transfugiens Zschacke, the involucrellum is absent.
