This species is our largesl Collybia although C. radirata some 

 times has ;i cap equal in width. The fleshy, ly cartilaginous, 



consistency of its stem may lead one to refer it to the genus Tricho 

 loma. Peck and others say the stem iv stuffed or hollow. I have 

 found the young stem solid-fibrous, later tunneled bj grubs, an«l 

 tli,. interior loosened. Insects attack the planl readily and ^i»»il 

 it for nse on the table, hut ;b it does not rank very high in flavor,
