Coprinus similis. B. & Br. 



Pileus campanulate-ovate, pallid, lineato-striate, disc 

 darker, hygrophanous, studded with brown-tipped acute 

 warts, which eventually disappear; stem white, hollow, 

 attenuated upwards; gills adnate, narrower behind, sub- 

 linear, blackish, margin brown.

 Hdbk., p. 227. 



On trunks of dead trees. Resembling Coprinus aphthosus, 

 but differing in the striate pileus. Pileus 1 in. across. 



**** Tomentosi. 



Coprinus extinctorius. Fr. 



Pileus 1^-2 in. across when expanded, submembranaceous, 

 cylindric-clavate, then expanded and campanulate, straight, 

 margin striate, at first clothed with floccose evanescent 

 scales, whitish, apex tinged with brown ; gills reaching the 

 stem, lanceolate, whitish, becoming brownish-black ; stem 

 4-5 in. long, 2-3 lines thick, slightly swollen at the base, 

 below which it is continued as a rooting-stem, smooth, white, 

 hollow ; spores 10-11 x 6 /*. 



Coprinus extinctorius, Fries, Epicr., p. 245; Cke., Hdbk., 

 p. 227 ; Cke., Illustr., pi. 668 ; Bolt., t. 24. 



On the ground about the roots of trees. Firmer than 

 neighbouring species, pileus splitting when expanded, but 

 not revolute, pallid, disc darker ; becoming glabrous from 

 the apex towards the margin, whereas in C.fimetarius the 

 disappearance of the floccose substance is from the margin 

 to the apex. (Fries.) 



Fries considers that Bolton's figure, pi. 24, is a poor figure 

 of the present species. The following is Bolton's account of 

 his species. 



The root is a little swelled, hard, white, and emits brown 

 fibres from the sides ; sometimes it sustains several plants, 

 sometimes only one ; it is not surrounded by a volva. 



The stem is cylindrical, smooth, white, fistular, with a 

 small perforation, wherein is a soft downy matter like 

 cotton ; it is an inch in circumference, and five inches high ; 

 there is no curtain. 



The gills are all in one series, extremely numerous, thin,
