 20. C. conglobata Burt, n. sp. Plate 19. fig. 15. 



Type: in Mo. Bot. Gard. Herb, and in Farlow Herb. 

 Fructifications cespitose, 10-30 together, sessile on a common 

 short trunk which is erumpent through the bark; individual 

 fructifications subglobose, fuscous and glabrous when moist, 

 drying mouse-gray and with the margin inrolled; hymenium 

 concave, black or nearly black; basidia simple, with four sterig- 

 mata; spores colorless, even, cylindric, slightly curved, 8-10 

 X 2J-3)u. 



Cluster 1-2 mm. in diameter, emerging about J mm. from the 

 bark; cups 400-500 ju broad, nearly as high. 



Clusters scattered on small limbs of Alnus, New Hampshire 

 and New York. July and September. 



The clusters of this curious fungus are distributed at the rate 

 of about 5 or 6 clusters to the square centimeter on what I con- 

 clude to have been the under side of a horizontal limb perhaps 

 a limb prostrate on the ground; for cups in clusters exactly on 

 this presumably under side have the pore central while in the 

 clusters which emerged more obliquely from the limb the cups 

 are somewhat auriform with oblique pore and are arranged in 

 imbricated manner. The outer surface of the cups is composed 

 of irregularly branched and interwoven pale brownish hyphse 

 about 2 /x in diameter. The substance of the fructifications 

 and common trunk-like base is composed of colorless hyphse 

 with walls gelatinously modified.
