Type: in Kew Herb., not found by me in Curtis Herb, al- 

 though sought for. 



Pileus coriaceous, flabelliform or obHquely cyathiform, paUid 

 to Hght bay-brown, somewhat zoned, glabrous and shining 

 towards the margin, bearing a cluster of coarse 

 hairs towards the base; stem, when present, 

 cylindric, scarcely 2 mm. long; hymenium even, 

 paler than the upper surface ; in structure 200-250 

 n thick, composed of longitudinally arranged and 

 somewhat interwoven hyahne hyphae 3 m in 

 diameter; no cystidia; gloeocystidia pyriform, 

 9-12X7^ ix; spores, as found in a crushed prepara- 

 tion, hyaline, even, 4X2^ /x, few found — noted by 

 Massee as subglobose, 5-6 /x in diameter. 



Pileus 6-10 mm. across. 



On dead Vitis in swamps. South Carolina. ^^s- ^- 



Reexamination of my preparation of the type Gloeocystidia x 

 of S. cristatum fails to demonstrate that the 665. From type, 

 pyriform organs in its hymenium are longitu- 

 dinally septate; furthermore some of these organs are more 

 elongated than stated above and irregular in form. For 

 these reasons I regard the bodies as pyriform gloeocystidia 

 rather than possibly miniature basidia of the longitudinally 

 septate type, the demonstrated presence of which would require 

 transfer of this species to Eichleriella. The occurrence of S. 

 cristatum on dead grape vines, the crest of coarse hairs towards 

 the base of the pileus, the small size of the latter, and the pyri- 

 form organs in the hymenium are a good group of characters 

 for identification of this species, although known so far only 

 from the original collections.
