Genus X. Omp.rophila Fr. Sum. Veg. Scand. 357. 1849. 

 Type species, Ombrophila violacea (Hedw) Fr. 



Mycelium within the substratum. Apothecia gelatinous, 

 sessile or substipitate, slightly concave becoming either plane or 

 convex, thick. Stipe when present, short and thick. Paraphyses 

 filiform, or somewhat clavate, simple or branched at the base. 

 Asci narrowly clavate. Spores 8, ellipsoid or oblong, hyaline, 

 guttulate. 



Growing on decaying wood. 



-\-Onibropliila ■z'iolascens Rehm Discom. 478. 1891. 



Apothecia solitary or in groups or caespitose 0.5-2.5 cm. 

 broad, varying in shape, interior faded red or dark reddish 

 purple, exterior of the same color, sessile or with short stipe, 

 gelatinous grisly. Hymenium hyaline or tinged with red, hy- 

 pothecium of the same color, central part of the cup red and 

 then hyaline, outer cells reddish. Paraphyses filiform, slightly 

 clavate, non-septate. Asci cylindrico-clavate, distended with 

 spores. Spores obliquely uniseriate or straight in the ascus, 

 simple, hyaline, guttulate, broadly elliptic, smooth, 6-9 mic. long 

 and 5 mic. wide.

 membranous, sessile or stipitate, superficial or at first immersed. 

 Hypothecium forming a distinct layer. Outer cells of the cup 

 dark colored, more or less rounded and thick-walled.
