Remarks (public):This species is distinguished by its positive reactions for both laccase and tyrosinase, its sensitivity to malachite green, cycloheximide, and benomyl, and growth on TAA. Bourdot and Galzin (1928) commented on Vuilleminia comedens "Il est assez voisin par sa structure de certains Aleurodiscus, notamment A. macrosporus et A. dryinus. Comme lignivore, il tranche avec l'ensemble des Corticium par sa grande activité." Boddy and Thompson (1983) indicate that it is capable of invading living branches. Boddy and Rayner (1983a) reported that Vuilleminia comedens, Phellinus ferreus and Stereum gaussapatum, are pioneer colonists, actively growing in partially living branches and causing extensive white rot but little cambial loosening. It was suggested that oidia or mycelial fragments may be dispersed in the sap of living branches prior to the development of decay; however, none of the three are known to produce conidia of any sort (Brefeld 1889, Boidin 1958a, Stalpers 1978, Nakasone 1990). Buysson (1920) noted the Staphyllinid Anisotoma calcarata Er. on the hymenium.

Description:Vuilleminia comedens (Nees: Fr.) Maire
References: Boidin (1958a), Boidin, Terra and Lanquetin (1968), Stalpers (1978).
Species code: 2ab.3c.(7).12(-211).26.32.36.(38-)40.(43-44-)45. (50).54.60.63.
Growth on MEA: Moderate, plates covered in 4 wk, to moderately slow, plates covered in 5 wk. Radius at 2 wk averaging 34.9 mm (24.8-53.5), at 6 wk averaging 100 mm. Margins even, submerged to appressed, fimbriate to wispy (long and sparse), hyaline. Aerial mycelium present. Mat at 2 wk sparse to moderate, of average depth to moderately deep, silky to farinose to downy to floccose to cottony to woolly, at 6 wk similar or plumose, or in part felty to crustose, zonate or azonate, hyaline to white. Reverse at 2 wk faintly bleached to bleached, or coloured, to pale yellow (4E2?), at 6 wk faintly bleached to bleached. Not fruiting within 6 wk. Odour nil to +, "fragrant" (nil or nondescript, or fruity, cantaloupe, almond, and with a strong heady volatile).
Microscopic characters: Marginal hyphae tubular, straight to undulating, thin-walled, 1.3-5.7 µm broad, with simple clamp connections, regularly branched. Branching at right angles, variously positioned, sometimes from clamp connections, or not associated with septa or clamp connections. Cultures monomitic, generative hyphae in older mat remaining thin-walled, predominantly tubular, with some peglike branching, smooth or commonly crystal-encrusted with crystals 1-2 µm broad, inamyloid, 0.8-3(-3.7) µm broad, with simple clamp connections. Capilliform hyphae present or absent, straight, peg-like, becoming branched and tangled, 0.8-1.2 µm broad. With hyphal coils (some branches end in a densely coiled knob), 3.5-6 µm in diameter. Crystals sometimes present in agar, tetrahedral, 3-5 µm broad, occurring singly. Submerged hyphae similar to aerial, inamyloid, 1.1-4.2(-4.7) µm broad, simple clamp connections, with scattered simple septa, thinwalled. Conidia lacking.
Growth on PDA: Moderately fast, plates covered in 3 wk, to moderately slow, plates covered in 5 wk. Diameter at 2 wk averaging 47 mm (27.8-83), at 6 wk averaging 128 mm (> 70 mm). Margins even to uneven (wavy), submerged to appressed, wispy (long and sparse), hyaline. Aerial mycelium present. Mat at 2 wk sparse to dense, low and thin to average, silky to downy to sparsely floccose, thinly woolly, granular, or velvety to felty, at 6 wk similar, mostly woolly-floccose, zonate or azonate. Mat hyaline to white to cream (4½A1½ to 4A2-4B2½ at 6 wk). Reverse at 2 wk unchanged to coloured, yellow (4½B4), at 6 wk coloured, pale yellow to brown (4A2, 4B3, 5B2-5C3-7C3-6½E4). Not fruiting within 6 wk. Odour + to 3+, "fragrant", "earthy or musty" or "other" (fruity, lemony or apple, often with yeasts, mould, wax, benzene or plastic tone, swimming pool, or old socks, and sometimes with strong, eye-burning, sinus-irritating volatile).
Growth on ML: Fast, plates covered in 2 wk, to moderately slow, plates covered in 5 wk. Diameter at 2 wk averaging 62 mm (36-85), at 6 wk averaging 169 mm. Margins even, submerged to appressed, fimbriate to wispy (long), hyaline. Aerial mycelium present. Mat at 2 wk sparse to dense, low and thin to average, moderately deep over the disk, silky to downy to cottony to woolly to floccose to plumose, at 6 wk with matted, felty centre and floccose-woolly to plumose rims, zonate or azonate.
Mat hyaline to white to cream (4B2-5B2). Reverse at 2 wk unchanged to coloured, pale yellow to brown (4A2-6D4), unchanged or similarly coloured at 6 wk (4A2-5C3-6C3). Not fruiting within 6 wk. Odour + to 4+, "fragrant" to "other" (nondescript or fruity, of durian or lemon, with yeasty, wax, methanol, benzene or swimming Pool tone, sometimes with cabbage or skunk cabbage, or strong heady volatile).
Growing on angiosperms (including Alnus, an undetermined hardwoods), heterothallic, tetrapolar (Tassinari 1956), nuclear behaviour heterocytic (Boidin 1958a).
Isolates studied: T-580, T-583 T-593 T-612, T-630.
