Remarks (internal):The principal characters enumerated in the original description of the genus were the hard, compact context, the vertically oriented, cyanophilous, simple-septate, moderately thick-walled hyphae and the internal basidial repetition. In addition to the type, two other species were included: Gloeocystidium karstenii Bourdot & Galzin and Thelephora ochracea Fr. Jülich (1984) did not distinguish the genus from Gloeocystidiellum. Hjortstam and Ryvarden (1988) emphasized the internal linear repetition of the basidia and the distinctly stratified basidiomes as principal features of the genus, and placed G. insidiosum in synonymy under Conferticium ochraceum. Ginns (1992) concluded that the type specimen of Corticium ravum Burt was identical with Conferticium karstenii.
Current status The principal characters remain essentially as originally described: 1) internal repetition of the basidia, 2) cyanophilous or acyanophilous, simple-septate, moderately thick-walled hyphae, 3) gloeocystidia (mostly), 4) amyloid spores, and 5) the hard context. Two species are placed in Conferticium: C. ravum and C. ochraceum. Both occur in North America.

Description:Conferticium Hallenb.
Mycotaxon 11: 447, 1980.
Type species Gloeocystidium insidiosum Bourdot & Galzin
Basidiomes effuse, typically several cm long and broad, thin to 0.6 mm thick, crustose, very dense, in age sometimes deeply fissured, yellow, pale yellow, buff, pallid to tan, lignicolous or corticolous. Hymenial surface smooth, but conforming to the topography of the substrate. Subiculum pallid to white, thin, hard, dense. Hyphal system monomitic. Generative hyphae typically arranged in a narrow layer parallel to and adjacent to the substrate, then becoming perpendicular to the substrate and slightly woven between the gloeocystidia and developing hymenium, lacking clamp connections, 2-4 µm diam, the walls hyaline, thin or moderately thickened, nonamyloid, cyanophilous or acyanophilous. Gloeocystidia cylindric or clavate, typically 35-120 x 4-10 µm; the walls hyaline, thin or sometimes thickened; the contents oily to granular and pale yellow in KOH, sulfo-positive or sulfo-negative. Basidia developing by internal repetition, cylindrical to slenderly clavate, about 17-36 x 4-6 µm with four sterigmata. Basidiospores ellipsoid, about 4-8 x 2-5 µm, the walls hyaline, thin, amyloid, acyanophilous, smooth or verruculose, with a minute apiculus.
