Description:CERACEOMERULIUS ALBOSTRAMINEUS (Torrend) Ginns
Mats white to Light Ochraceous-Salmon, moderately thin, around inocula appressed to slightly raised, subfelty to downy, then becoming slightly raised to raised, downy to cottony toward margins at 2 wk, by 6 wk some isolates white to Pale Pinkish Buff, moderately thin, around inocula appressed to slightly raised, subfelty to downy, then becoming slightly raised to raised, cottony to woolly toward margins, other isolates Buff Pink to Pecan Brown, moderately thin, appressed, subfelty throughout; margins even, appressed to slightly raised; odor sweet at 2 wk, absent or sweet at 6 wk; agar unchanged at 2 wk, unchanged or Light Russet Vinaceous to Russet-Vinaceous at 6 wk; not fruiting by 6 wk.
MEA 23-40; (47-)60-90+; TAA -, 0; GAA -, tr-18; (tr-)20-42; TyA -, 23-50; (30-)60-80(-90+)
Microscopic characters: Marginal hyphae 2-4 µm diam, thin walled, simple septate, sparsely branched, usually branches arising below septa. Submerged hyphae 1.5-7 µm diam, thin walled, simple septate except for rare single clamps, frequently branched, also developing scattered hyphal swellings up to 10 µm diam. Aerial and surface hyphae similar to submerged hyphae except coated with reddish brown, resinous materials that dissolve in 2% KOH. Bulbils numerous in submerged and Trial mats at 2 wk, absent at 6 wk.
Sexuality: Presumed homothallic (Ginns 1976, p. 105).
Cultural descriptions: Ginns (1976, p. 110); Stalpers (1978, p. 186).
Species codes. 1. 3r. 2l. (22). 26. 32. 36. (38). 39. 44-46.50.54.55. (57) 1. 6. 7. 32. 36. 38. 40. 45-47.50.54.55. (57). (Ginns 1976, p. 112).
Remarks: The associated decay of Ceraceomerulius albostramineus is in dispute. It is reported to be associated with a brown rot (Ginns 1976, p. 109) and a white rot (Gilbertson 1974, p. 44 as Byssomerulius armeniacus (Bres.) Gilbn.). This species is widely distributed throughout temperate North America on gymnospermous and angiospermous wood (Ginns 1976). Cultures frequently become degenerated. These cultures develop mats that are reddish brown, appressed, thin, and subfelty throughout.
