more rarely on frondose logs. In Europe, Canada to Texas, 

 and westward to British Columbia and California, and in Vene- 

 zuela and East Indies. June to December. Probably common. 



C. lividum may be recognized by its livid fructifications of gray, 

 reddish, or bluish tinge and of somewhat gelatinous consistency, 

 somewhat suggestive of those of Peniophora gigantea in aspect but 

 destitute of cystidia. C. hepaticum seems to me referable to 

 C. lividum but I need to study the type again in the feature of 

 the slightly reflexed margin, which I now suspect may be that of a 

 different species overrun by C. lividum. Since the tubercules of 

 the Grandinia ocellata form are due to heaps of imbedded crystals, 

 it has seemed to taxonomists that this species is a Corticium 

 rather than a Grandinia.
