CLASSIFICATION 345 



C. ovatits. — Cap ovate, then expanded, 2-4 in. high, at first 

 covered with a pale ochraceous cuticle which becomes broken up 

 into concentric rows of scales, edge striate ; gills whitish, then 

 blackish umber ; stem 3-5 in. long, white, bulbous ; ring soon dis- 

 appearing. 



Differs from C. comatus in its smaller size, striate edge of cap, 

 concentrically arranged scales and fugacious ring. 



In pastures. 



C. sterqmlinHs (PI. XXV, fig. 5). — Cap conical, about 2 in. across 

 when expanded, coarsely grooved, at first silky, disc with erect 

 squamules, sih-ery grey, disc tinged brown, thin ; gills free, pale, 

 then purple-umber ; stem 4-6 in. high, white, fil rillose, base thick- 

 ened, sheathed by the volva for about an inch from the base, 

 margin of volva ending in a free margin. 



Known by the squamulose disc of the cap, and the sheathing 

 volva. 



On dung. 



C. obledits. — Cap i in. or more across, cylindrical, then conico- 

 campanulate, whitish and silky, then smooth and pale tan-colour, 

 grooved, powdered with rosy meal ; gills narrow, becoming blackish 

 with a tinge of flesh-colour ; stem silky, white, with a short ad- 

 hering volva having a free, refiexed edge. 



Distinguished by the rosy meal on the cap. 



On dung, etc. 



C. umhriniis. — At first entirely enclosed in a white volva. Cap 

 conico-hemispherical, soon almost plane, coarsely grooved up to 

 the disc, about 2 in. across, ornamented with patches of the volva ; 

 gills free ; stem 4-5 in. long, dark umber from the first, base 

 bulbous, with a persistent white volva ha\'ing a free, reflexed edge. 



Readily distinguished from its nearest ally, C. stenocoleus, by 

 the sulcate cap and umber stem. 



On manured ground. 



C. sqiiamosus. — Cap thin, ovoid, then expanded, grey, covered 

 with reddish brown scales, about i in. high, up to 2-| in. across when 

 expanded ; gills free, ventricose ; stem 4-6 in. long, smooth and 

 white above the ring, covered with reddish brown scales below. 



Readily known by the scaly cap and lower part of stem. 



At the base of trees, stumps, etc. Tufted. 



C. volvaceominimus. — Cap campanulate, then expanded, striate, 

 grey with white squamules, up to I in. across ; gills slightly ad- 

 nexed, narrow, blackish purple ; stem smooth, hyaline, base 

 bulbous, up to I in. long, volva with a broad, free margin. 



A minute species, differing from C. bender sonii in having a dis- 

 tinct volva and subglobose spores ; C. bidbillosus differs in the 

 absence of a marginate volva.
