uniform, somewhat dense, but looser in centre, of much inter- 

 woven, frequently septate hyphae, 8-io/x in diameter. Basidia 

 long, conspicuous, up to 6o/x long, 5-6/u, wide, contents granu- 

 lar; sterigmata 2. Spores subglobose, smooth, hyaline, with 

 basal apiculus, and a large guttule, 9-1 1 x 8-9 /n (or 9-10 /u, 

 in diameter). 



Habitat. In woods and shady spots. Common. 



This species varies in habit from simple to very branched 

 forms, and the surface may be exceedingly rugose to almost 

 smooth. It is generally recognisable, however, by the distinct, 

 irregular, longitudinal wrinkles, and the large spores.

 Trans. Brit. Myc. Soc. vi. 1917, p. 62. 



This variety is unknown to us, it is said to differ from the 

 type in the dark, sooty colour of the clubs and flesh. It has 

 been collected recently in England by Mr. Carleton Rea. 



Habitat. On the ground, Caughley Wood, Salop, 1917.

Plants simple, slender, gregarious, 2-3 cm. high, pure white. 

 Clubs cylindrical, fragile, smooth, hollow, apex blunt or pointed. 

 Stem slender, greenish at the base, not markedly distinct from 

 the club. Internal structure pseudoparenchymatous in trans- 

 verse section. Basidia clavate, 30-40 x 8/x; sterigmata 4. 

 Spores hyaline, globose, with long, scattered spines, spore-body 

 7-8 /x in diameter. 



Habitat. On bare soil, rare. Specimens from Haslemere 

 (A. D. C, 1905; E. M. W., 1913). 



This species is distinguished from other white simple forms 

 by the globose, distinctly spiny spores. C. tenerrima Mass. 

 et Crossl. is similar in habit, but the spores are described as 

 granular. The latter has not been met with since it was 

 described, and is therefore listed here among the doubtful 

 species. 



{b) Plants drab or greyish.
