Plants branched, 3-8 cm. high, gregarious, fragile, pure 

 white, pinkish white, or with a tinge of mouse-grey; smell 

 none, taste distinct. Stem short, slender or stout. Branches 

 numerous, irregular, flattened upwards, and divided at the 

 tips into sharp-pointed branchlets; axils rounded. Flesh 

 white. Inter)ial structure composed of loosely interwoven, 

 more or less parallel filaments, fairly regular, frequently septate, 

 segments 35-40 x 5-6/x, in the centre 50-70 x 6-9/x. Basidia 

 small, 25 X 6-7 /x, contents densely granular; sterigmata 2. 

 Spores smooth, hyaline, subglobose, apiculate, 9-12 x 6-8 /u, 

 (av. g X yfji or 7-8 /n diam.), with a large conspicuous oil- 

 globule. 



Habitat. On the ground in woods, etc. Very common. 



We have retained this species in the sense in which it is usually 

 understood, but not without some misgivings. It is obviously 

 nearly allied to C. cinerea, and small crested forms of the latter 

 are difficult to distinguish from certain forms of C. cristata. 

 It is noteworthy also that C. cristata usually occurs in more 

 shaded spots, and frequently covered with leaves or screened 

 by logs of wood. 



The black parasitic mould Scoletotrichum Clavariarum occurs 

 perhaps more frequently on this species than on any other.

 gregarious, brittle, ivory to creamy white, base sometimes 

 pink; smell none, taste pleasant. Stem usually distinct, 1-2 cm. 

 long, 3-5 mm. thick, but sometimes absent. Branching irre- 

 gularly dichotomous, or irregular, loose or rarely compact; 

 branches erect or spreading, cylindrical or slightly compressed,
