Closely related to /.. theiogalus. The Latter has ;i more truly viscid 

 pilens which is usually qo1 zoned, and an odor which i- well marked 

 ami disagreeable. /.. chrysorheua is sometimes frequent locally bnl I 

 have so far not happened upon it in many Localities, h may be

 in the United States it is often subviscid in moist weather. Tin- 

 milk sometimes turns slowly ami the taste is occasionally bitter-
