PILEUS L.5-4 cm. broad, campanulate-convex, obtuse, then Bub 

 expanded and subumbonate, doI Btriate, densely innately fibrilb 

 hairy, unicolorous, light i>r<>irnixli nine (Ridg.), Bcarcely shining,

The typical C. raphanoides is said to have a strong radish odor 

 and acrid taste. These were lacking in our plants, and only in 

 some respects is it very close to thai species. Its sphagnum habital 

 in conifer woods also seems to point to a distinct species, it differs 

 from ('. valgus in its fibrillose hairy pilens and stature. No such 

 plant is described from the United States. There are no violaceous 

 hues present. 



SUBGENUS TELAMONIA. Pileus hygrophanous, its color 

 changing on losing moisture, not viscid, glabrous or sprinkled on the 

 margin with the superficial fibrils of tin 1 universal veil; flesh rela- 

 tively thin, scissile. Stem peronate or annulate from the remains 

 of a universal veil. 



This and the following subgenus are closely related by the liy- 



grophanous character of the pilens. by which they are both separated 

 from the subgenera fnoloma and Dermoeyhe. To quote Ricken : "IU 



'hygrophanous' we designate a pilens whose surface is not compact 

 lint composed of loose tissue which absorbs Water readily and when 



soaked with moisture has quite a different color than when dried out. 

 After several experiences this peculiarity is recognized at the first 

 glance. If one is uncertain about it. the plants collected in dry 



weather are placed in a dish of water." and then allowed to dry
