Specimens examined:

and in Mo. Bot. Gard. Herb., 43891). 
20. M. albus Burt, n. sp. 
Type: in Mo. Bot. Gard. Herb. 
Fructification resupinate, effused, thick, somewhat сот- 
iaceous-fleshy, separable, white when received, becoming 
somewhat cartridge-buff in the herbarium, the margin thin- 
ning out; hymenium reticulate-plicate near the 
EN () margin, at the center porose with shallow, 
Fig. 18 angular, unequal pores about 1 or 2 to a mm.; 
h^ adl: in structure 700-800 д thick, with the folds 
See ok lA ^ standing out up to 300-500 д further, com- 
’’ ' posed of hyaline, thick-walled, compactly in- 
terwoven, stiff hyphae 41-5 ц in diameter towards the 
hymenium, with occasional hyphae 7-8 д in diameter near 
the substratum, not inerusted, not nodose-septate ; no cystidia; 
spores hyaline, even, 6-74 3-33 и, flattened on one side. 
Fructification 41-7 em. long, 21-4 em. broad. 
On pine bark and adjacent earth. Alabama. June. Rare. 
M. albus may be recognized among our resupinate, white- 
spored species by its white color, firm structure, thick fructi- 
fication, large angular pores, coarse hyphae, and much larger 
spores than other species of this section. It approaches Рота 
but should, I believe, be regarded as a Merulius.
