78 NATURAL HISTORY BULLETIN 



Gregarious, sessile, or with a short stem, about .5 to 1 cm. in 

 diameter, externally clothed with very few minute white hairs; 

 hymenium bright orange ; asci cylindrical, 8-spored ; spores el- 

 liptical, 1-guttulate, externally covered with net-like reticula- 

 tions, giving the spore a roughened appearance, 22 to 25 by 12/i,; 

 paraphyses slender, enlarged upwards, filled with orange gran- 

 ules. 



In woods among moss (Polytrichum) , Iowa City, rather com- 

 mon. 



Specimens described under this name are vecry interesting. 

 The plants are distinct from the preceding in the size, habi- 

 tat, and in their more decidedly stipitate character. They have 

 always been found by the writer among the same kind of moss 

 and in some cases were thought to grow from the stems of the 

 mosses among which they are more or less immersed, but this 

 could not be determined with certainty. 



The plants described here have reticulate spores similar to 

 those of the preceding. In the Discomycetes of Eastern Iowa 

 this fact was mentioned and illustrated with the statement that 

 in no available description were the spores of Peziza rutilans 

 Fries described as being reticulate although they were always 

 described as rough. 



Since that statement was made a reference has come to hand 

 (Grevillea 22 : 108) in which the description drawn from a speci- 

 men named by Fries as Peziza rutilans states that the spores are 

 delicately reticulated. The specimens described here conform 

 well in that particular with authentic material, a point concern- 

 ing which the writer was in doubt at the time the first record 

 of the species was published. 



In some respects these plants resemble more closely those of 

 Peziza polytrichi Schum. The plants especially when young are 

 quite hairy often with a distinct white fringe around the margin 

 but older specimens are more nearly smooth or only slightly 

 downy. The stem-like base is also a prominent character.
