330 The North American Cup-Fungi 



on sandy or gravelly soil, as indicated b\' the particles adhering 

 to the base of the apothecia. 



On March 10, 1914, the writer received still other specimens 

 from Mr. Carl A. Schwarze, of the New Jersey Agricultural 

 Experiment Station. These plants, which were found growing 

 in the sand of a cutting bench in one of the greenhouses, were 

 accompanied b>' the following description: "First of all the 

 plants were gregarious, had a short but distinct stem, cups 

 concave, nearly white and translucent when young, a yellowish- 

 brown when old, later becoming repand and umbelicate, and 

 more or less angular. The stem is obscured b\' the expanding 

 disc. The largest disc became convex and measured at least 

 10 cm." 



In April of the same year, similar specimens were collected 

 by Mr. L. O. Overholts in a mushroom cellar in Missouri. These 

 specimens, which were referred to the writer, were accompanied 

 by the following description: "Cups 3-8 cm. broad, somewhat 

 stipitate, margin involute, depressed in the center, hymenium 

 smooth, ochraceous-buff (Ridgw.) or somewhat more brownish, 

 exterior covered with white meal." 



All of the American specimens referred to above agree well 

 with specimens of Peziza domiciliana from the herbarium of 

 Cooke, so far as we can judge from dried specimens. According 

 to Cooke, the apothecia are sessile, although in our American 

 specimens the\' are, at least when young, short-stipitate. Also 

 we have not noted an\' of the violet tints referred to by Cooke, 

 although in his original description he allows for a rather liberal 

 range of color. The spore measurements of the American and 

 European specimens are identical. The \oung plants are always 

 pure-white and usually the flesh when broken turns golden- 

 yellow. This fact was noted by Bresadola and was found to be 

 true of specimens collected in New York. Whether this character 

 is constant, we are unable to say, since no attention was given 

 to this in some of the plants when fresh. From the studies 

 which have been made, the writer feels safe in referring our 

 American plants to Peziza domiciliana Cooke, and also in 

 regarding this species as distinct from Peziza repanda Pers.". 



Since the publication of the above notes, numerous specimens 

 of fungi referable to this species have been received, a few of 

 which are as follows: 1915, on the ground in greenhouse, Missoula,
