globose, minutely apiculate, very small, 3-5-4'5ft in diameter, 

 one-guttulate. 



Habitat. In long grass in woods and pastures. Uncommon, 

 but in certain seasons frequent. 



This species is very distinct in its beautiful ivory-white 

 colour and loosely branched habit. When well grown it may 

 form tufts 4 to 5 inches high and as much across, but average 

 plants are decidedly smaller. From C. riigosa it is distinguished 

 by being branched from the base and by the slender, even 

 (not rugose) branches, and from C. cristata by the loose habit, 

 lunate axils, and non-cristate apices. From both it differs in 

 the very small spores. 



The type specimens of C. chionea are in the Persoon herbarium 

 at Leyden, and Dr. Goethart reported that they agreed in form 

 and size with British specimens of C. Kiinzei which were sub- 

 mitted to him. 



With regard to C. Kromhholzii , this species was based by 

 Fries on Krombholz, tab. 53, figs. 15, 16, and tab. 54, figs. 18-20, 

 which the latter had referred to C. Kunzei. It differed 

 principally in being less branched and in the branches being 

 somewhat flattened. C. Kimzei however is well known to be 

 a very variable plant, and it sometimes assumes forms which 

 correspond with the description given for C. Kromhholzii. No 

 plants have been seen under the latter name which were 

 specifically distinct from C. Kunzei or C. rugosa.

Plants branched, very variable in habit, usually 3-5 cm. in 

 height, but sometimes more, solitary or gregarious, greyish or 

 with a faint tinge of purple, rather brittle; smell none, taste 

 mild. Stern more or less distinct, thick, short. Branching 

 irregular, repeated, uneven, axils usually acute; branches 

 thick or slender, cylindrical or compressed, short, stuffed, 

 erect, wrinkled, apices often toothed. Flesh white. Internal
