Peziza 233 



Similar in habitat to the preceding but apparently distin- 

 guished by the small size of both apothecia and spores. The 

 plants occur more on isolated cow dung than on manure piles as 

 does the preceding.

Apothecia gregarious, sessile, deep cup-shaped to subdiscoid, 

 externally whitish, nearly smooth or minutely pustulate, the 

 margin even or slightly wavy and crenate, reaching a diameter 

 of 3-8 cm.; hymenium umber-brown; asci cylindric above, 

 gradually tapering below, reaching a length of 200-235 /x and a 

 diameter of 13-15 n; spores 1-seriate, with the ends slightly over- 

 lapping, hyaline, smooth, 9 10 X 15-20 m; paraphyses strongly 

 enlarged above, reaching a diameter of 7-8 /x at their apices. 



On rubbish piles and soil in woods. 



Type locality: Europe. 



Distribution: New York to California; also in Europe.

This may be Peziza cerea Sow. the identity of which seems to 

 be uncertain. The species is common in woods and often 

 approaches Peziza repanda in size and general appearance. The 

 latter seems to differ however in its more repand habits as well 

 as in habitat, occurring on rotten logs.

Apothecia gregarious but not usually crowded, at first globose, 

 gradually expanding, soon becoming shallow cup-shaped, finally 

 discoid, regular in outline or occasionally more or less distorted 

 when old, becoming closely adnate to the substratum on the 

 under surface, except the extreme margin, which is free and
