Verrucaria cryptica (Arnold) J. Steiner, nom. inval., Verh. zool.-bot. Ges. Wien 61: 41, 1911

Amphoridium crypticum Arnold, nom. inval., Lich. Frank. Jura 257, 1885. Basionym.

Type.

[Italy] An Kalksteinen einer Schutthalde unterhalb der Kalkwände an der Südseite des Latemar -Gebirges oberhalb Predazzo, Südtirol, 21. Aug. 1883, Arnold (H-NYL 7009!, H!, UPS-L-169663!, isotypes).

Description.

Prothallus absent. Thallus endolithic, grey. Perithecia 0.15-0.39 mm, (3/4-)1-immersed in rock, leaving deep pits in the rock. Involucrellum absent or possibly in some perithecia, small apical involucrellum. Exciple ca. 0.25-0.40 mm in diam., apex thickened, wall black, ca. 30 mm thick. Periphysoids ca. 50-70 × 2 mm, branched-anastomosing. Ascospores 0-septate, 25-30(-32) × (12-)13-16(-17) mm, perispore 1(-1.5) mm thick, persistent.

Notes.

The species is rather similar to V. foveolata, but the halonate perispore seems to be persistent. This species seems not to have been validly published as the species description is missing from Arnold (1885) and Steiner (1911).
