Brief Description:

Lentinula raphanica (Murr.) Mata & R.H. Petersen comb. nov. FIGS. 5-7.
= Armillaria raphanica Murrill. 1943. Mycologia 35: 35: 422. [!]
= Gymnopus alliaceus Murrill. 1943. Mycologia 35: 425. [!]
Pileus convex at first, then broadly convex to shal-lowly depressed; surface glabrous to suede-like, not striate, often wrinkled inward, hyigrophanous overall; disc at first “russet” to “ochraceous tawny”, then “vi-naceous cinnamon”, “pinkish cinnamon”, “cinna-mon buff”, “pale cinnamon-pink”, outwards “pink-ish cinnamon”, “pinkish buff” to off-white, bruising “walnut brown”; velar remnants sometimes as appen-diculate scales near margin, more or less zonate; mar-gin strongly inrolled, appendiculate at first, with membranous white veil. Flesh up to 3 mm at disc, off-white to "cream-buff’; odor none to mild; taste none at first soon with unpleasant, cabbage-like af-tertaste. Lamellae free to seceding, delicate, close to crowded, narrow to subventricose, thin, “pale pink-ish cinnamon”, “pale cinnamon-pink”, to off-white; edge smooth, eroded in age. Lamellulae numerous. Stipe central to eccentric, equal, sometimes twisted; surface scurfy to shaggy, above with erect floccose fi-brillose scales, longitudinally lined, “pinkish buff”, “pale cinnamon-pink”, to off-white towards base, in some bruising brown (7D8) to red-brown (8E6); con-sistency tough. Annulus absent. Habitat gregarious, on Quercus spp. wood and other hardwood; in forest vegetation. Pileipellis a repent cutis, rarely embedded in ge-latinous matrix; hyphae 1.5-7(10) tjm diam., tightly interwoven, occasionally with short, erect or diverti-culated outgrowths, pigment-encrusted, sometimes banded, light brown, with clamp connections; wall thin. Pileus trama loosely interwoven; hyphae 3-16 jm diam, hyaline, constricted at septa, with clamp connections; wall up to 1-5 Jim thick. Rarely, oleifer-ous hyphae present, 3-5 jLm diam. Lamellar trama regular to subregular, becoming interwoven towards edge; hyphae 2-12 JLm diam, hyaline, with clamp connections; walls thin to 2 μm thick. Subhymenium ramose, 2-4 cells thick. Basidia 16-26 X 4-7 μm, clavate to sphaeropedunculate; sterigmata (2-3)-4, up to 8 μm long. Pleurocystidia absent. Cheilocystidia (FIGS. 5a, b) (13)17-28(50) X 3-10 μm, mainly clavate, fusoid, contorted, branched, rarely ampullaceous, with clamp connections; apex obtuse, mucronate, knobbed or with diverticulate outgrowths. Lamella edge sometimes fertile. Stipitipellis parallel; hyphae 3-14 μm diam; walls up to 1-4 μm thick. Caulocystidia (FIG. 6) 10-35 X 3-7 μm, cylindrical, clavate or flexuous, apex obtuse, knobbed or with outgrowths. Basidiospores (FIG. 7) 4.8-7.2 X 2.0-3.6 μm (A = 5.7 ± 0.58 X 2.7 ± 0.32 μm, Q = 1.50- 3.00, Qx = 2.16 ± 0.28, n = 215/10), narrowly ellip-soid to subovoid in side view, subcylindrical in front view, hyaline, inamyloid; wall thin, smooth.
