ITALIC 8.0

Catillaria baliola (Nyl.) Orange

in Cannon & al., Revisions of British and Irish Lichens, 22: 12, 2022.. Basionym: Lecidea baliola Nyl. - Flora, 59: 308, 1876.

Synonyms: Catillaria chalybeia var. chloropoliza (Nyl.) H. Kilias

Distribution: S - Cal (TSB 16250).

Description: Thallus crustose, thinly episubstratic, grey-green to dark grey, 0.1-0.2 mm thick, continuous to rimose, rarely areolate. Apothecia lecideine, 0.4-0.7(0.8) mm across, adnate or weakly constricted at base, with a dark grey-brown to black, slightly convex to flat disc, and a black to grey proper margin. Proper exciple dark brown to brown-black, often colourless on the outer trim in lower part, without green pigments, N-; epithecium brown, without green pigments, N-; hymenium completely colourless, 40-60 µm high; paraphyses mostly simple, lax, 1.5-2 µm thick at mid-level, the apical cells capitate, to 5 µm wide, with a dark cap; hypothecium dark brown, K-. Asci 8-spored, cylindrical-clavate, with a K/I+ blue outer coat and a K/I+ uniformly blue apical dome, Catillaria-type. Ascospores 1-septate, hyaline, oblong-ovoid to oblong-ellipsoid 8-12 x 2.5-3.5 µm. Pycnidia usually abundant, black, the wall dark brown. Conidia bacilliform, 3-4 x 1-1.3 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.

Note: according to Orange (in Cannon & al. 2022) the distinction of this species from C. chalybaea is supported by the absence of green pigments in the apothecia, by the amphibious freshwater habitat, and by molecular data.
