The short fi in. to 1 in. long), inilated, decumbent podetin, with thfir 

 thickened and"freque:itly dark brown apices, characterize tliis form. In 

 more branched specimens the pndetia are somewh tt aggregate, but when 

 simpler thev are often somewhat discrete, owing to the nature of the 

 habitat. The apothecia are extremely rare, and even the spermogones 

 are seldom visible.

From the clusely allied C. uncialis this, when well developed, is easily 

 known bv the podetia being scyphifercus, moi'e slender, and close. AVhen 

 ascyphous, as it oft-'U occurs, it is apt to be confounded with that species, 

 though even then it must be recarded as distinct. With us the apothecia 

 are very rare, and the spermogones only occasionally present.
