Family 41. TRYBLIDIACEAE 

 Rehm 191 

 Apothecia innate, then erumpent or superficial, opening by lobes or rarely by

 occasionally cespitose or stromate; hymenium exposed at maturity, hypothecium 

 well developed, thick; asci mostly cylindric, 8-spored; paraphyses numerous, much 

 branched or swollen, at the tip; spores various. 



This family differs from Phacidiaceae only in the better developed hypothecium 

 and hymenium, and from Dermateaceae in opening by lobes or a cleft rather than
