H. appendiculatitm (PI. XXVI, fig. i). — Cap 2-3 in. across, ovate, 

 then expanded, smooth, bay-brown when wet, whitish with an 

 ochraceous tinge, wrinkled, and somewhat sparkhng when dry ; 

 veil in fragments at edge of cap, but soon disappearing ; gills 

 whitish, then brownish flesh-colour ; stem 2-3 in', long, white, 

 smooth. 



Densely tufted. Fragile. Differs from H. candoUcunitm in the

H. catariiim. — Cap up to f in. across, expanded, smooth, ochra- 

 ceous, paler when dry ; gills whitish, then brown ; stem about 

 1 1 in. long, white, rather shining, apex striate, base thickened and 

 downy. 



Among grass. Subcajspitose. 



H. leiicotephrum. — Tufted. Cap 2-3 in. across, subcampanulate, 

 wrinkled, then expanded and whitish ; veil here and there in 

 fragments at the edge ; gills greyish white, then blackish ; stem 

 3-4 in. high, silky-fibrous, apex grooved, ring large. 



Differs from H. candollcaniim and H. appendiculatitm in the cap 

 not being brown when 3'oung and moist, and in the gills not being 

 brown. 



H. egenidum. — Cap about i^ in. across, hemispherical, then 

 expanded, umbonate, watery white, snow-white when dry, polished, 

 veil in fragments at edge of cap ; gills purplish umber, edge white ; 

 stem about 2 in. long, whitish.

H. pilidcEforme. — Cap up to i| in. across, globose, then expanded, 

 smooth, brown when moist, dingy ochre when dry ; gills white, 

 becoming brownish ; stem about i in. long, smooth, white. 



Resembles a small form of H. appendiculatum, differing in the 

 gills having no tinge of flesh-colour. 



A ring is present in the young state. 



H. hydrophilnm. — Cap 1-2 in. across, convex, then almost plane, 

 wrinkled, disc even, bay when moist, tawny ochre when dry, edge 

 slightly incurved and split, veil hanging in shreds at first, but 

 soon disappearing ; gills pallid, then brownish, exuding drops of

Very much tufted, fragile, resembles in general appearance 

 Psilocyhe spadicea, from which it differs in the absence of a rosy tint 

 in the gills. Very similar to H. appendiculatum, but widely difi'erent 

 in the gills exuding drops of water, and in this feature agreeing with 

 H. velatinum, although differing in other important features. 



At the base of trunks, stumps, decaying posts, etc.
