PHOTOGRAPHS AND DESCRIPTIONS OF 

 CUP-FUNGI— V. PEZIZA PROTEANA 

 AND PEZIZA VIOLACEA 



Fred J. Seaver 

 (With Plate i, Containing 2 Figures) 



During the summer of 191 5, several collections were made of a 

 Peziza which agrees with Boudier's description and illustration 

 of Aleuria proteana. The species occurs on old burnt places 

 which have been thoroughly overrun with mosses. The apothe- 

 cia when young are beautiful waxy- white but with age become 

 slightly colored, smoky or with a tinge of pink, which occasion- 

 ally runs over to lilac. 



The habitat, size, and character of the spores would indicate a 

 close relationship with Peziza violacea, a species which is com- 

 paratively common on charcoal beds and recently burned places. 

 The latter species, however, has a deep-violet hymenium which 

 in aged specimens is almost black, the contrast in color being so 

 marked that the plants could scarcely be referred to the same 

 species, although their similarity in other respects cannot escape 

 notice. The following descriptions and photographs have been 

 drawn from fresh material collected in the outskirts of New 

 York City.
