Apothecia gregarious, sessile or short-stipitate, at first sub- 

 globose, expanding, becoming circular in form or elongated and 

 irregular; hymenium plane or slightly concave, deep-orange, 

 darker than the exterior of the apothecium; the cells of the 

 excipulum vertically elongated and subhyaline, giving rise below 

 to white mycelial threads by means of which the apothecia are 

 attached to the substratum; asci cylindric or subcylindric above, 

 tapering below into a long stem-like base, reaching a length of 

 250 )U and a diameter of 15 /x; spores 1-seriate, granular within 

 and usually containing one large oil-drop, reaching a diameter 

 of 10-12 m; paraphyses branched below, only slightly enlarged 

 above, reaching a diameter of 2-3 m at their apices. 



On recently killed foliage of various species of Jiiniperiis, 

 Ctipressus, Thuja and Sequoia. 



Type locality: Europe.

Excluded Species 



Pithya suecia (DeBary) Fuckel, Symb. Myc. Nacht. 3: 32. 1875. 

 According to Rehm, this is a synonym of Lachnellula chrysophthalma (Pers.) 

 Karst., a species which occurs in North America. The species belongs with 

 the inoperculate discomycetes and is not a true Pithya.
