Sclerophora pallida (Pers.) Y.J. Yao & Spooner
Kew Bull., 54, 3: 688, 1999. Basionym: Calicium pallidum Pers. - Ann. Bot. (Usteri), 7: 20, 1794.
Synonyms: Coniocybe curta H. Magn.; Coniocybe nivea var. pallida (Pers.) Arnold; Coniocybe pallida (Pers.) Fr.; Coniocybe pallida var. leucocephala (Wallr.) Schaer.; Coniocybe subpallida Nyl.; Sclerophora nivea (J.F. Gmel.) Tibell
Description: Thallus endosubstratic, poorly evident. Apothecia at first sessile and covered with a yellow pruina, then stalked and pin-like, 0.4-0.7 mm high, the stalk 0.06-0.1 mm thick, straw-yellow to pale grey in old specimens, epruinose, translucent when wet, consisting of hyaline, non-sclerotized, periclinally arranged hyphae. Capitulum broadly ovoid to lenticular, 0.25-0.32 mm across, the mazaedium well developed, pale ochraceous, densely inspersed with minute, dark yellow crystals. Exciple well-developed, forming a basal collar, of anticlinally oriented, hyaline hyphae, the surface covered in a layer of colourless to yellow crystals (pruina); hypothecium pale yellowish brown, with a slightly convex upper surface. Asci clavate, with a single functional wall layer, without apical structures, K/I-, dissolving at early stages, formed singly from ascogenous hyphae with croziers, with 2-seriately arranged ascospores. Ascospores 1-celled, globose, hyaline, 7-8 µm wide, with a verrucose ornamentation. Photobiont trentepohlioid. Spot tests: all parts of the ascomata including the yellow pruina K-, C-, KC-, P-, except the crystals in the mazaedium, which react K+ fleeting purple-violet (often with the formation of large crystals). Chemistry: thallus without lichen substances.
