a thin sub-fimbriate, white margin. Spores abundant, glo-

 C. LEPTALEUM E. & E., Field Mus. Bot., i 1170 (1896). 



Type habitat: On underside dead sapling Magnolia 

 Frascri, alt. 1,800 ft. April 11, 1895 (Nuttall, discov. 1803, 

 690). 



Thin, closely adnate, grayish-white, pulverulent, soon 

 cracking into areas 2 to 3 mm. across, with margins incurved 

 so as to resemble the shallow cups of some Peziza. Spores 

 oblong, hyaline, continuous, 10 to 12 x 4 /x, borne on cyl- 

 indrical basidia 30 to 40 x 6 fx, with two stout sporophores. 

 There are also other smaller (immature) ? sporidia, globose 

 (4 to 6 /x) or elliptical, 5 to 7 x 3 to 3.5 fx. The membrane 

 on which the hymenium stands where exposed on the in- 

 curved margin of the pezizoid areas is pale brown.
