Description:Tomentella ochracea (Sacc.) M. J. Larsen, comb. nov. Figs. 106-111 (W).
Holotype: U.S.A., New Jersey, ad lignum mucidum, J. B. Ellis 3540, in herb. P. A. Saccardo (PAD).
Basidiocarps up to 0.5 mm thick, mucedinoid, normally adherent to occasionally separable; fertile area continuous when mature, brown vinaceous to dull purplish brown, sometimes dull avellaneous to buff (10.0 R 5/2 to 10.0 R 6/2, or 5.0 YR 4/4); hymenial surface smooth; Subiculum firm-fibrous, very pale tan or hyaline to pale yellow; sterile margin up to 1.0 cm wide, fibrillose to fimbriate, pale yellow to distinctly yellow; cordons evident at 10X; basidiocarps often acquiring a dark green tint when exposed to KOH.
Subicular hyphae very variable in form and dimension, (2.5-)3-5 (-7) µm diam, septate, with clamps frequent, often ampullate and appearing constricted at the septa, wall thickening slight or noticeably thick-walled, some hyphae becoming irregular or swollen, normally hyaline, infrequently pale yellowish brown, hyphal contents infrequently dull yellowish brown in KOH; cordons up to 80 µm diam, hyaline to very pale tan, individual hyphae 2-4 µm diam, clamped, hyaline; subhymenial hyphae 3.5-6(-7) µm diam, clamped, constricted at the septa, septa often closely spaced and then appearing torose, thin-walled, hyaline, contents frequently dull yellowish brown in KOH, exterior parts of cell walls often dull green in KOH; basidia 30-40 x 7-9 µm, clamped at the base, transverse septa infrequent, clavate, hyaline, contents sometimes pale yellowish brown in KOH, parts frequently dull green in KOH, 4sterigmate, sterigmata up to 6 µm long; basidiospores (Figs. 106-111) 7--8.5(-9) µm across, globose, irregularly subglobose or globose, usually elongated along one axis, aculeolate to echinulate, pale to medium brown.
Remarks: Tomentella ochracea is readily identified by its normally brown vinaceous to dull purplish brown fertile area, pale yellow to distinctly yellow subiculum, presence of cordons, and form of basidiospores (see Figs. 106-111). Tomentella ochraceo-olivacea may be a form of T. ochracea, but the former is characterized by a pale ochraccous brown fertile area, a hymenial surface that is minutely colliculose in part, and absence of cordons.
