Volvostropharia amanitoides Minakata nov. gen.
Neither with gills rounded behind and adnexed to ventricose as in Hypholoma (F.) coscus Fr., nor with stem sinuato-adnate with a decurrent tooth like H. (F.) punctulatus Kalchbr. these two becoming only the Flocculosi described in Massee's Brit. F. Fl., vol I, 1892, pp. 390. Differs from H. appendiculatum Bull., in the thick base of the stem, etc. Extensively gregarious or tufted and caespitose, now connate at base, very fragile, smell none, taste mild. Stem slender, up to 9 cm. l., 2-10 mm. thick, somewhat angular or compressed, now witha groove, erect, curved or crooked near the more or less thickened, tuberous, rigid base, which is obtuse, furnished now with slender root-fibres and coated with white cottony flocci embracing comminted stone particles etc., pallid, subequal or tapering upward, finely silky, shining satin- like, minutely punctato-squamulose, above sulcato-striate and fleshy-fibrillose, shining, stuffed with yellowish homogeneous fibrils, then fistulose, distinct from the thoroughly very thin sporophore with a demarcation line. Pileus 5 cm. diam. at most, now unequal or excentric, lubricous when moist, first subovoid with a rather truncate base, provided with a thin porously interwoven white veil, which soon vanishes leaving appendiculate fragments at the margin but apparently nothing on the stem, then campanulate, at last expanded, in damp situations lurid, otherwise pale ochraceous, subdepressed squamules, that become transversely concentric towards the inflexed entire margin, which turns at last laciniato-crenate and turning at the extremity, near which now with a zone of sooty brown, becoming glabrous and shining like talc, and atomate under a lens, closely striate up to the bottom of the broad obtuse, shallowly umbilicate umbo, quite even to plicato-undulate, subfleshy and now deep coffee-brown from the fallen spores. Gills crowded, pallid then flesh-coloured turning purplish brown, the very minutely crenulate edge white, irregularly in4 or5 series, the shortest much narrower and vein-like, and flexuoso-interrupted, others plane becoming crisped at front extremity, thin, soft, rather dry, linear and narrow, obtuse in front, broadly adnate, afterwards seceding. The flocculent base now adpressedly circumscissile in volva- like manner.
