Armillaria (Collybioidea) tumulosa Minakata
Whole plant rigid, rather fragile, cracking with a sound, when torn. Taste mild, scent strong, like new meal. Densely caespitose, containing in one chester 30-80 individuals of different age. Stem coalescent below, but not forming much a rumpish mass, 1/2 - 3 in. long, 2 - 8 lin. thick, erect or curved, coated with white cottony flocculi below, above buff or buffish white, or umber-brown, minutely furfuraceo-velutinous, flaccid, cracking and exposing the innate silky- fibrils, which are white and splitting, vellum superior, white, flocculose, obsolete, apex expanding, at first densely farinaceo-furfuraceous, rough, [at first greyish, then whitish ?] shortly streaked with obsolete ridges continuing down from the gills, firm, cartilaginous, rigid, inside white, becoming tinged fuliginous, compact, solid, streaked but not evidently fibrose, expanding above with the sporophore, which is almost homogeneous with it, and distinct from rather thin cuticle, which is cartilaginous, rather inseparable, emitting sound when tried to peel with finger nail. Pileus at first convex, or oblate, very obtuse or depressed in the centre, becoming unequal or irregular, now sinuato-incised at one side, zoned obsoletely at few times, then expanded, becoming plano-convex, up to 2 in. diam., vescid then dry, dirty umber-brown, looking like dung, here and there crustaceous and ruggedly from the dirty ochreous gluten when dry dirty buffish, the disc remaining umber, minutely crustaceo furfuraceo-punctate under a lens, thinly coated with whitish very minute flocculi on the periphery as if white washed, margin involute, somewhat wavy in outline, edge remaining involute, exceeding the gills, at first more distinctly coated with minute white silky flocculi, the remnants of the vellum, flesh, rigid, firm, thickish at disc, abruptly much attenuating towards the margin, where it is very thin. Gills pallid white then cream-color, or color straminous, or clear straminous, at first rounded behind and now with a collar on one side of the stem, afterwards adnate, with an obscure continuation as ridges on the apex of the stem, linear, narrow, up to 1 1/2 lin. broad about the middle where broadest, front a short cutish, exceeded, arcuate, thin coriaceous, blunt, tough, not fragile, emitting sound when straked, moist, crowded, lax, in irregular 4-5 ser., now once or twice forked, now redundant, now obfurcate, now crooked, the interstices free, edge whitish, somewhat wavy, surface sulcato-striate across.

コメント：闘鶏神社で採集されたナラタケArmillaria属の未記載種である。種小名のtumulosa（墓の）は採集地に由来するものであろう。それにしても本菌の彩色図はかなりラフである。色があせたせいもあるが、全体の図はかなり雑な印象がある。学名も書き直した跡があり、文字もかなり走り書きのようで、追加で書き足した跡がある。
