Remarks (public):Some isolates of this species usually tested negative for tyrosinase, while others usually gave positive reactions. This species is distinguished by its sensitivity to both malachite green and cycloheximide, restricted growth and strong clearing on BCP-MSG agar, and positive reactions for laccase. Boidin and Beller (1966) distinguished the European species A. wakefieldiae from A. oakesii by details of spore shape and ornamentation, the occurrence in the former of occasional clamp connections, and the occurrence in the latter of tyrosinase in culture. Among the many imaginative observations reported by Massee (1889) were verticillate, phialosporic conidiophores on fruiting bodies of Stereum hirsutum and the production of gonidia (conidia) on the hymenium of Aleurodiscus oakesii and A. amorphus. The conidia he observed in A. oakesii probably represent the thick-walled, terminal knobs of the pseudocystidia in this species, which do disarticulate readily in squash mounts, although they appear to lack a wall closing the line of disarticulation, and to lack cytoplasmic contents.

Description:Aleurodiscus oakesii (Berk. & Curt.) v. Höhnel & Litsch.
Species code: 2ab.6.8.(26).27.31cg.32.36.(38-)(40).(45-)47. (53).54.(57).
Growth on MEA: Moderately slow, plates covered in 5 wk, to very slow, plates not covered after 6 wk. Radius at 2 wk averaging 22.5 mm (6.9-47.5), at 6 wk averaging 67 mm (> 16 mm). Margins even to uneven, or bayed, submerged to appressed, fimbriate, or wispy, or plumose, hyaline. Aerial mycelium present. Mat at 2 wk dense to moderate, low and thin, or moderately deep, silky to downy to cottony to woolly to floccose to felty, at 6 wk silky to greasy to farinose to downy to woolly to floccose to felty to crustose, azonate, or zonate (depth), hyaline to white. Reverse at 2 wk unchanged, at 6 wk unchanged, or faintly bleached, or bleached. Not fruiting within 6 wk. Odour nil to +, "other", or (nil or weakly fishy, cabbagey or fungoid, of white-rot, old toilet, old shoes or yeasty).
Microscopic characters: Marginal hyphae tubular, straight, thin-walled, 1.4-3.5(-6.7) µm broad, with sparse, simple septa, regularly branched. Branching angle various, not associated with septa or clamp connections. Cultures monomitic, generative hyphae in older mat predominantly tubular, smooth, inamyloid, 1-3.5(-5.7) µm broad, simpleseptate, with wall up to 1 µm thick, sometimes slightly inflated, constricted at septa, or with swollen branching points (to 5.9 µm broad). Capilliform hyphae present, or lacking, tangled, 0.9-1.5 µm broad, occasionally with some hyphae in parallel fascicles. Crystals
present among aerial hyphae, polarized, chunky (singly or in rosettes, 9-12 µm broad), or plate-like (in rosettes, to 10 µm broad), and in agar, nonpolarized, tetrahedral (8-10 µm broad, singly), singly. Submerged hyphae similar to aerial, inamyloid, 1.2-5.1 µm broad, simpleseptate, thin-walled, and undifferentiated or with patches of nodular-contorted interlocking branches. Conidia lacking.
Growth on PDA: Moderate, plates covered in 4 wk, to very slow, plates not covered after 6 wk. Diameter at 2 wk averaging 35.4 mm (8-59), at 6 wk averaging 97 mm (a 29.5 mm). Margins even, submerged to appressed to raised, fimbriate to wispy, hyaline. Aerial mycelium present. Mat at 2 wk sparse to dense, low and thin to moderately deep, silky to downy to woolly to felty, at 6 wk similar, to cottony or floccose, zonate (in depth, or shade), or azonate. Mat hyaline to white, or cream, or pale greyish yellow (4A1½, 4½B3). Reverse at 2 wk unchanged to coloured, pale yellow to orange-brown (4A2, 5AB2½, 6½C4), at 6 wk similar (4A2, 6½C2, 5D3). Not fruiting within 6 wk. Odour (+) to 3+, "fragrant" or "other" (ammonia, bile, urine, cured leather, fish, peanuts, shreddies, deep-fried wontons, fruity-fragrant, sometimes in combination, artificial maple, cantaloupe, pears, almond, and ethanolic yeasty).
Growth on ML: Moderate, plates covered in 4 wk, to very slow, plates not covered after 6 wk. Diameter at 2 wk averaging 43 mm (17-66), at 6 wk averaging 115 mm (2: 62.5 mm). Margins even to uneven, submerged to appressed, fimbriate to wispy to plumose, hyaline. Aerial mycelium present. Mat dense to moderate, low and thin to average, cottony to woolly to floccose to felty, at 6 wk silky to woolly to floccose to felty to crustose, zonate. Mat hyaline to white, or cream, (4½AB2). Reverse at 2 wk unchanged, or coloured, pale yellow (3A2), at 6 wk unchanged, or faintly bleached, or coloured, pale yellow or brownish orange (4A2½, 6CD2, 7D4). Not fruiting within 6 wk. Odour (+) to 3+, fragrant to "other" (fishy, fungoid or mouldy, cabbagey, bile or yeasty).

Growing on angiosperms (including Quercus, Ostrya). Apparently primarily homothallic, possibly holocoenocytic (Boidin, Terra and Lanquetin 1968).
