Description:STECCHERINUM SUBRAWAKENSE Murrill
Mats white, thin, appressed and subfelty throughout or limited around inocula then becoming slightly raised, arachnoid toward margins at 2 wk, by 6 wk white to Cartridge Buff, thin to moderately thin, appressed, and subfelty throughout, developing small, irregular, thick, felty patches scattered over mats, some isolates developing scattered, diffuse or discrete, tough to leathery, Cartridge Buff fertile areas, these areas grandinioid at first, finally developing well- defined teeth when mature, isolate FP 103201 developing small, 5 mm diam., effuse-reflexed basidiomata on side of dish with well-developed teeth and white cottony margins; margins even to bayed, appressed, fimbriate; odor sweet and fruity at 2 and 6 wk; no agar discoloration at 2 and 6 wk; fruiting by 6 wk.
MEA 34-64; (84-)90+; GAA ++++, 0 ; TAA ++++, tr ; TyA yellow, 32-47; 80-90
Microscopic characters: Marginal hyphae 2.5-5 µm diam., thin walled, nodose septate, sparsely branched, usually branches arising 14-18 µm below septa. Submerged hyphae 1.5-3.5(-5.5) µm diam., thin walled but wider hyphae becoming slightly thick walled by 6 wk, nodose septate, moderately branched; by 6 wk some becoming inflated up to 10 µm diam.. Surface hyphae (a) similar to submerged hyphae except wider hyphae becoming thick walled by 2 wk and some segments heavily encrusted with hyaline, crystalline. materials; (b) fiber hyphae 1.5-3.5 µm diam., sometimes with intercalary swellings up to 8 µm diam., thick walled but thinning toward apex, tapering slightly at apex or enlarged up to 8 µm diam, clamped at base, rarely branched, occasionally lightly to heavily encrusted with hyaline crystals, absent or numerous at 2 wk, rare to numerous at 6 wk.
Species code: 2. 3c. 8. 26. 27. 32. 36. 38. 43-44. 48.50.54.
Remarks: Steccherinum subrawakense occurs on angiospermous wood in Florida (Murrill 1940; CFMR records). Unfortunately, there are no outstanding characters that distinguish this taxon in culture from other Steccherinum species.
