360 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Type: type and cotype in Kew Herb. and Curtis Herb. 
Fructification small, orbicular, flattened, wholly resupinate, 
probably separable, fleshy, drying fuscous-black, the margin 
thinning out, entire; hymenial surface pitted with very shal- 
low, angular pores about 5 to a mm., with thin, entire dis- 
sepiments; in structure 400 џ thick, with dissepiments extend- 
ing 9-12 и, composed of compactly interwoven hyphae 43 д 
in diameter, which ascend somewhat obliquely to the hymenial 
surface, not incrusted, not nodose-septate, hyaline in the 
region near the substratum, becoming fuscous towards the 
hymenial surface; no cystidia; no basidia; a few spores—per- 
haps foreign—in and along the hymenial surface appear very 
slightly colored, even, 33x 23-3 и. 
The three fructifications comprising the cotype range from 
4 to 3X2 mm. 
On very rotten wood whitened and disorganized into 
strands by weathering and decay. Connecticut. 
Since the fructifications show no basidia and afford no evi- 
dence that a hymenium is continuous over the edges of the 
dissepiments, or that the porose stage is preceded by hymenial 
folds, the position of this species in Merulius must be re- 
garded as very doubtful until confirmed by better specimens.
