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).
