菌名：Tricholoma hilarum Minakata

F. 772 Duplicate.
Nom vulgar: Shiratake In hilly woods, ? Muro, Kii, brought in by Mr. Nisaburo Sakamoto, Nov. 17, 1913.
Tricholoma (Limacina) hilarum Minakata
Gregarious ? Flesh moist, not juicy, elastic, cartilaginous in section, but at the same time fragile, cracking with a sharp noise when pressed. Taste slightly sour then bitterish, smell none. Stem very robust and proportionately short, base rotund and very thick, ending with an abrupt indurated obconical point, white, the part uncovered by the pileus, becoming soon stained rusty tan, smooth, innato- sericeous, the lower part adnate with almost connate inseparable pellicle, which is evidently viscid at first, and is now divided into inconspicuous more or less linear unequal squamules, now with a zone of slight depression where the pileus had touched the stem in its nascency, above rough, with whittish thin yellowish fascecled flocci, which are now capped with tawny pruinoso-pelliculose fragments, the silky ground more coarse and distinct, apparently pitted or areolate surrounded by the tufts, cylindrical, angular or compressed, very rigid and firm, flesh white, becoming tinged yellowish, solid, compactly fibrillose, heterogeneous with the sporophore, which is thick, rather abruptly attenuating towards the margin, as rigid and compact. Pileus at first equal, becoming now equal or very oblong, or irregularly unequal, up to 2 in. diam., convex then plano-convex, now depressed at the disc, now subrepand, coppery lateritious, pallid at the extremity of margin, viscid, soon dry, then glabrous or minutely papillose, or minutely innato-squamuloso-fibrillose, margin always involute, shortly and closely plicate and streaked with acute then obtuse ridges at the extremity, at first covered with white woolly, short, thickish, rather in separable. Gills pallid, becoming cream-color, then tawny and tainted rusty at the edge, which is thin, truncate and irregularly wavy in outline, becoming torn and cross, very numerous, crowded, more or less lax and curved, becoming imbricate, irregularly up to 3 series, now forked one or twice, fragile, emitting sound when stroked, slightly moist, tramellosely finely striate across, the interstices free, linear, narrow, up to 2 lin. Broad near the front where broadest, front acute, involute, exceeded by the margin of pileus, plane narrowed behind, sinuato-adnexed, determinate, without any decurrent tooth, not easily separable from the sporophore, closely ruguloso-sulcate across towards the base. Stem at first rotundo-ovate, abruptly contracted at the apex, then somewhat elongated and shortly obclavate. Learned from Mr. Sakamoto, that it was quite insipid when cooked after being stewed to deprive it of its alkaline constituents. Pileus at first pallid white, the stem as well, as was evinced by a single specimen found by myself under Gleichenia dichotoma on shady hill side, Horai, prope Tanabe, November 11, 1917. --flesh rosy-colored just beneath the cuticle

コメント：複数のシートからなるキシメジTricholoma属の未記載種。種小名のhilarumは「ヘソ」の意味なので、最初の図に出ているような印象をもとにしたものと思われる。当初カヤタケClitocybe属の一種と同定していたが、Tricholomaにしたことが分かる。
