188 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



[Vol 10 



clusters standing out from the substratum and near together, 

 with their main trunks up to 6\i in diameter and short-celled ; 

 no cystidia nor gloeocystidia; basidia simple, 15 X 4^(i, with 

 4 sterigmata; spores hyaline, even, flattened on one side, 4-4 ^ 

 X 3-4 [l, copious. 



Fructifications scattered along the substratum, 1-3 cm. long, 

 4-8 mm. wide. 



On dead herbaceous stems, Hawaiian Islands, F. L. Stevens, 

 881, type. 



Epithele hydnoides Burt, n. sp. 

 Type: in Mo. Bot. Gard. Herb. 



Fructifications effused, adnate, drying pallid to olive-buff of 

 Ridgway, very thin, 30 (x thick, with often not more than a 



basal cell between each basidium and the substratum ; hymenium 

 a plane surface parallel with the substratum and bristling with 

 conical hyphal fascicles about 10 to a mm. which start from the 

 substratum ; hyphal fascicles 90 \i long, 20-30 \l in diameter at 

 the base, with crystalline matter in the axis; basidia simple, 

 20-30 X 12 ji, with 4 large, divergent sterigmata; spores hyaline, 



globose, 9 p. in diameter, copious along the surface of the hyme- 

 nium but none seen attached to the sterigmata. 



Fructifications in numerous small patches 5 mm.-2 cm. long, 

 2-4 mm. wide, often becoming confluent. 



On dead stems of Cibotium, Hawaiian Islands, F. L. Stevens, 

 957, type. 



Under a lens the fructifications have the aspect of a whitish, 

 resupinate Hydnum but the hymenium does not clothe the 

 organs resembling teeth. The whitish color, large, globose 

 spores, and large basidia distinguish E. hydnoides from other 

 species of the same genus.
