Remarks (public):This species is distinguished in culture by the development of an orange reverse on PDA, ML and sometimes on MEA, and growth on both TAA and GAA, with positive reactions, if any, only on the former.

Description:Acanthophysium lividocaeruleum (P. Karsten) Boidin
Species code: (1).2a.4.15.(21).31g.32.36.(38-)39(-40).(44-)45(-47).(50-52).66.59.65.
Growth on MEA: Moderate, plates covered in 4 wk, to very slow, plates not covered after 6 wk. Radius at 2 wk averaging 31.4 mm (18-53.5), at 6 wk averaging 89 mm (a 56 mm). Margins even to uneven, submerged to appressed, fimbriate to finely wispy, hyaline. Aerial mycelium present. Mat at 2 wk sparse, low and thin, silky to downy to woolly to floccose, at 6 wk silky to woolly to floccose, azonate, hyaline to white to pale yellow to orange (4½A2-6A1½). Reverse at 2 wk unchanged, faintly bleached (66% of the mat), or coloured, yellow (4A2), at 6 wk unchanged, faintly bleached, or coloured, yellow or brownish orange (4A3, 5A4, 6B4). Not fruiting within 6 wk. Odour nil to 3+, "fragrant" to "other" (lemon oil, fruity, almondy, papaya, coconut, sometimes also yeasty).
Microscopic characters: Marginal hyphae tubular, straight, thin-walled, 1.4-5(-6.3) µm broad, with sparse simple septa, or rarely with simple clamp connections, sparsely branched. Branching from or opposite clamp connections, or not associated with septa or clamp connections. Cultures monomitic, generative hyphae in older mat remaining thin>walled, predominantly tubular, smooth (with rare or scattered, resinous to amorphous-solid, polarizing masses up to 10 µm long adhering), inamyloid, 1.3-4.1(-6.2) µm broad, with more frequent simple clamp connections and rare simple septa, sometimes with swollen branching points, the broadest hyphae being gloeopleurous hyphae with reddish sap that is unreactive in sulfobenzaldehyde. With capilliform hyphae at margin, straight and largely unbranched, to tangled, 1-1.5 µm broad. Crystals present among aerial hyphae and in agar, or lacking, tetrahedral, 5-6 µm broad, single. Submerged hyphae similar to aerial, inamyloid, 1-6 µm broad, simple-septate or with simple clamp connections, thin-walled, tubular or faintly monilioid. 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 41.3 mm (25.3-63), at 6 wk averaging 89 mm (> 48 mm). Margins even, submerged, appressed, or raised, fimbriate to wispy, hyaline. Aerial mycelium present. Mat at 2 wk sparse to dense, low and thin to average, silky to downy to cottony to woolly to floccose, at 6 wk silky to woolly to floccose, azonate. Mat hyaline to white or pale orange, (6B3-6½B4½). Reverse at 2 wk coloured, slightly brownish orange to orange (6AB3-6C4>7A5), at 6 wk coloured, brown to orange (5½B4-8C5). Not fruiting within 6 wk. Odour 2+ to 3+, "fragrant" to "other" (fragrant to fruity or pungent: almonds, apples or rotten apples, lemony, yeasty, sometimes with acetone, phenolic or rotted cabbage odour).
Growth on ML: Moderate, plates covered in 4 wk, to very slow, plates not covered after 6 wk. Diameter at 2 wk averaging 58.8 mm (a 31 mm), at 6 wk averaging 139 mm (> 45 mm). Margins even, submerged to appressed, fimbriate, hyaline. Aerial mycelium present. Mat sparse, low and thin, silky to downy to woolly to floccose, at 6 wk silky to farinose to woolly to floccose, azonate. Mat hyaline to white or pale orange, (6A1½-6AB3). Reverse at 2 wk coloured, yellow to orange or brownish orange (4/B4, 6A3, 7C5), at 6 wk similar (5A3, 6B3½-7½B5). Not fruiting within 6 wk. Odour 2+, "fragrant" to "other" (fruity: apples or lemony, sometimes with phenolic, vanilla, menthol, yeasty, or rotted cabbage overtones, or of peanut butter or pancakes).
Growing on gymnosperms (including Pseudotsuga, Thuia, Tsuga). Heterothallic, bipolar, astatocoenocytic (Boidin, Terra and Lanquetin 1968).
Isolates studied: T-588, T-590, T-625, T-657, T-682.
