Remarks (internal):There is only one specimen in the type collection, and in the dried state it's appearance is quite unlike the type collection of Clitocybe atrialba Murrill. Previously, I (Bigelow, 1965) had thought the two species were identical, but a recent comparison convinced me that C. oculata is quite distinct by the pale colors from C. atrialba. Singer (1942) was correct in recognizing the two species, although I do not agree with his placing them in different genera. My examination (and reexamination) did not reveal a hypoderm or lamellar cystidia in C. oculata. The specimen did not revive perfectly throughout, however, and possibly cheilocystidia could have been missed in sectioning.

Description:Clitocybula oculata (Murrill) Bigelow, comb. nov.
Clitocybe oculata Murrill, Mycologia 5: 210. 1913.
Hydropus oculatus (Murrill) Singer, Lloydia 5: 129. 1942.
"Pileus convex to plane, slightly depressed at the center, thin, solitary, reaching 4.5 cm. broad; surface dry, smooth, finely furfuraceous, avellaneous, fuliginous at the center, margin very thin, entire, even, concolorous; lamellae short-decurrent, distant, white; spores broadly ovoid, smooth, hyaline, granular, 9-12 x 7-8 µm; stipe equal, twisted, hollow, with a tough rind, furfuraceous, whitish with a pale avellaneous tint, 6 cm. long, 5 mm. thick.
"Type collected in low woods, probably attached to buried wood, at Mill City, Oregon, November 9, 1911, W. A. Murrill 835. The stipe of this species is rather tough for Clitocybe. The species is characterized by its coloring, its furfuraceous surface, and its unusually large spores."
The microscopic characteristics of the type specimen are: Spores (8.5-)10-12(-13) x 6-9 µm, broadly elliptic or ovate, smooth, amyloid. Basidia 32-46 x 6-8.5 µm, 2-spored. Cystidia not found on lamellae. Pileus cutis mostly consisting of pilocystidia, usually clavate to clavate-bulbous and often pedicellate, sometimes ± fusoid or cylindric, 19-68 µm long, 6-12.5 µm in diam, smooth, with brownish intracellular pigment, some cylindric hyphae also present in cutis, 2.5-6 µm in diam, hyaline or brownish; context hyaline, hyphae broad cylindric or inflated, 4-15.5 µm in diam, cells long, walls thin or thickened. Hymenophoral trama of ± parallel hyphae, cylindric or broad cylindric, (3-)6-22 µm diam, subhymenium of interwoven cylindric hyphae. Oleiferous hyphae present. Clamp connections present.
