even, solid. Internal structure composed of loosely and slightly 

 interwoven filaments, 5-10/u. in diameter (average 7-8 ju,). 

 Basidia small, 35-40 x 6-7/11, contents finely granular; sterig- 

 mata 4. Spores hyaline, smooth, pip-shaped, laterally apicu- 

 late, 4-5 X 4jM or 5-6 x 3-4/t>t, usually guttulate. 



Habitat. On lawns. Uncommon. 



C. nmhrinella is a well-marked and somewhat uncommon 

 species. It is distinguished by its short branched habit, like 

 that of C. cornicidata var. pratensis, and by its pale brown colour. 



Owing partly to the poorness of Berkeley's figure a good 

 deal of uncertainty has existed as to its identity. Part of the 

 original gathering which exists at Kew, however, shows the 

 characteristic pip-shaped spores. The specimens taken together 

 with Berkeley's description and his rider that "The habit is 

 that of C. fastigiata" leave no doubt as to the plant he had in 

 view.

Plants unbranched, densely tufted, somewhat flexuous, 

 brittle, white, about 4-6 cm. high. Clnbs cylindrical, sometimes 

 twisted and compressed, apex acute, smooth, fragile, becoming 

 hollow. Stem not distinct. Internal structure of parallel, 

 septate hyphae, with rather long cells, pseudoparenchymatous 

 in transverse section, central cells 10-15 /x 'n diameter, with 

 smaller cells intermixed. Basidia small, 30 x 6-7 /a; sterig- 

 mata 4. Spores smooth, hyaline, subglobose, minutely apiculate 

 at the base, 3-5 x 3-4/x. 



Habitat. In meadows, etc. Common, especially early in 

 the autumn. 



Easily distinguished among the white species by the densely 

 tufted habit, very fragile clubs and small spores.
