Mats white to Cream Buff, thin, appressed, subfelty throughout or limited around inocula, then becoming moderately thick, slightly raised to raised, irregularly woolly to cottony toward margins, some isolates with Pale Ochraceous-Buff to Light Ochraceous-Buff fertile areas scattered over mats and inoculum plugs, fertile areas begin as cottony to mealy, pulvinate, mycelial balls, which then develop numerous, slender spines to cover the entire surface at 2 wk, by 6 wk white to Ochraceous Buff, thin, appressed to slightly raised, subfelty to subtomentose with scattered to numerous cottony mycelial tufts, fertile areas white to Light Buff to Cinnamon-Buff, odontoid to hydnoid, coalescing, formed over inocula and scattered over mat surface, spore print on dish lid white to Vinaceous-Cinnamon; margins appressed, even to slightly uneven; odor sweet at 2 wk, absent or spicy-sweet at 6 wk; agar unchanged or partially bleached at 2 wk, bleached at 6 wk; some isolates fruiting by 2 wk, most fruiting by 6 wk. ; GAA mats at 2 wk white, thin, appressed, subfelty throughout or moderately thin, slightly raised to raised, arachnoid to cottony throughout; margins bayed.

Microscopic characters: Marginal hyphae 3-7(-14) µm diam, thin walled, simple septate with scattered single and multiple clamps, sparsely to moderately branched. Submerged hyphae (a) as in marginal hyphae; (b) 1.5-6 µm diam, thin walled, simple septate, with scattered single clamps on wider hyphae, moderately branched. Surface and aerial hyphae (a) as described for marginal hyphae except some becoming slightly thick walled; (b) similar to submerged hyphal type (b) except 2-3 µm diam, slightly thick walled to thick walled, and often encrusted with abundant, tiny, hyaline, crystalline materials and yellowish brown resinous materials that dissolve in 2% KOH. Chlamydospores globose to limoniform, 7-12(-18) x 7-18 µm, thin walled to slightly thick walled, terminal or intercalary, numerous throughout mats at 2 and 6 wk. Hymenial elements as described from basidiomata. Sexuality: Presumed homothallic (Boidin & Lanquetin 1984b, p. 223).
Species code: (1). 2.5. 21. 34. 36. 40. 41-42. (57).
Remarks: --Donkia pulcherrima is associated with a white rot (Gilbertson & al. 1975) of angiospermous and occasionally of gymnospermous logs, and is widely distributed in eastern U. S. A., and especially common in the southeastern U. S. A. (Banker 1906; Miller & Boyle 1943; Coker & Beers 1951). Gilbertson & al. (1975) report D. pulcherrima from New Mexico. Culturally, D. pulcherrima resembles some Phanerochaete species
