Type: in Burt Herb. and N. Y. Bot. Gard. Herb. 
Fructification effused, soft, membranaceous, separable from 
the substratum, drying primuline-yellow throughout, with the 
margin a little paler; hymenium even, eracked, somewhat pul- 
verulent; in structure 400 и thick (1) with the 
hyphae loosely interwoven next to the sub- 
stratum, 34145 yw in diameter, occasionally 
nodose-septate, frequently more or less in- 
crusted, and (2) with the hyphae more densely 
arranged in the subhymenium, more regularly 
incrusted, and containing many heavily іп- 
crusted, cylindric cystidia 8-9 и in diameter, 
which do not protrude beyond the surface of the 
hymenium; hymenial cystidia usually not in- 
crusted, 5-7 u in diameter, emerging up to 30 и, 
occasionally with a few incrusting granules near 
the base; spores concolorous with the hyphae and й 204 я:

Substratum not noted. Jamaica. January. 
Although I have seen but a small portion of a fructification, 
which does not afford data as to margin or substratum, this 
portion shows a species which should be readily recognized 
by its bright yellow color throughout, peeling away from the 
substratum in a compact sheet, small spores flattened on one 
side, and by heavily incrusted, wholly buried cystidia.
