Family 40. STICTIDACEAE 



8:647; Rehm 112 



Apothecia innate, never concrete with the epiderm, finally more or less erumpent 

 as a rule, opening by lobes, by a cleft or lid or circularly, round to elongate, white 

 or bright-colored, or rarely dark but at least never black, typically waxy, rarely 

 membranous, separate or grouped; hymenium well exposed at maturity in most 

 cases, hypothecium poorly developed; asci mostly cylindric, 8-spored; paraphyses 

 usually numerous, and swollen at the tip, rarely subulate, simple or branched; spores 

 various. 



This family contains many genera with elongate apothecia, but these are readily 

 separated from similar forms in the Hysteriaceae by the color and consistency, as 

 well as by the fact that the disk is widely exposed at maturity. The Ostropae may 

 be placed almost equally well in either. 



Subfamily Eustictidae 



Rehm 113 



Apothecia waxy, not deeply sunken, finally opening widely and exposing the 

 hymenium more or less completely.
