Description:DENTIPELLIS DISSITA (Berk. & M. A. Curtis) Maas G.
Mats white, thin to moderately thin, around inocula appressed to slightly raised, subfelty to downy, then becoming raised, arachnoid to cottony toward margins at 2 wk, by 6 wk mats similar except in rare cases Pale Ochraceous-Buff; margins even, raised; odor faintly pungent at 2 and 6 wk; agar unchanged at 2 wk, unchanged or Naples Yellow to Primuline Yellow at 6 wk; not fruiting by 6 wk.
MEA (33-)40-55; 90+; GAA ++++, 0-tr; TAA ++++, tr-21; 30-42; TyA -, 11-33; 22-85
Microscopic characters: Marginal hyphae 3.5-5.5 µm diam, thin walled, nodose septate, sparsely branched, usually branches arising about 10-15 µm below clamps. Submerged hyphae 1-6.5 µm diam, thin walled to slightly thick walled, nodose septate, moderately branched. Aerial hyphae 1-6(-8) µm diam, similar to submerged hyphae except a few of the wider hyphae filled with opaque materials and some segments encrusted with hyaline crystals. Gloeocystidia or gloeoplerous hyphae cylindrical to clavate, sometimes enlarged at base, 80-200 x 2-6 µm, clamped at base, occasionally papillate or branched, filled with opaque, pale yellow materials, numerous in aerial mats at 2 and 6 wk. Chlamydospores globose to limoniform, 6-10 x 5-8 µm, hyaline, slightly thick walled, intercalary or terminal, numerous throughout mat at 2 and 6 wk. Resinous, hyaline, refractive materials abundant in aerial and surface mats at 6 wk.
Sexuality: Bipolar (Ginns 1986b, p. 42). Cultural descriptions: Brown (1935, p. 664 as Odontia separans (Peck) C. A. Brown); Ginns (1986b, p. 41).
Species codes: 2. 3c. 15(p). 21. 34. 36. 38. (39). 2a. 3. (15). (21). 34. 36. 38. 44. (48).54.59. (Ginns 1986b, p. 42).
Remarks: Dentipellis dissita is associated with a white rot of woody angiosperms in eastern Canada and northeastern U. S. A. (Ginns 1986b). This species is readily identified in culture because of numerous, small chlamydospores and gloeocystidia or gloeoplerous hyphae that are present. Stecchericium seriatum also produces small, thick-walled chlamydospores and gloeocystidia or gloeoplerous hyphae in culture but has a much slower growth rate on MEA as compared to D. dissita.
