7. S. Patouillardii Burt, n. sp. 
S. (very near) Leprieuri? (Mont.) Patouillard, бос. Myc. 
Fr. Bul. 16:55. 1900. 
Type: in Burt Herb. 
Fruetifieation resupinate, effused, coriaceous, dry, velu- 
tinous, aniline-black at first, becoming fuscous in the her- 
barium, the margin rather thick and determinate; in struc- 
ture 200-400» thick, with (1) next to the 
substratum a thin layer of loosely inter- 
woven hyphae За in diameter, buffy brown 
| | under the microscope, which form (2) а 
layer of hyphal pillars each about 30-50 
in diameter, 100-200» long, about 3-4 to a 
+ "- 
millimeter, whose hyphae spread apart 
4 |! above and form (3) the interwoven hyme-

spore-bearing orga erect, nearly straight, fuscous hyphal 
p, four paraphyses or | l * . ° 
hyphal ends. x 640. branches or paraphyses 2а in diameter; 
probasidia hyaline, subglobose, 15-20» in 
diameter, erect on short branches of the colored hyphae; 
no spores found; the only possible spore-bearing organ seen 
is 46 X 714, acuminate at the apex. 
Fructifications 2-315 em. long, 1-2 em. broad, 200-400 mm. 
thick. 
On living branches of ash, Liquidambar, and Nyssa. Flor- 
ida to Louisiana. November to March; a January collection 
has a few probasidia. 
This species may be recognized by its thin fructification 
resembling a piece of black velvet, slightly raised from the 
hcm on such short and slender pillars as to be barely 
visible without the aid of a lens. Patouillard determined 
this species for Mr. Langlois as very near to S. Leprieurit. 
Since Corticium Leprieurii was originally described as gla- 
brous, shining, and chocolate-colored, and since no specimens 
like ours have yet been collected in the region between Guiana 
and the United States, our specimens are probably a distinct 
species which should have a definite name.
