BURT—THELEPHORACEZ OF NORTH AMERICA. II. 343 
glabrous, flattened and ligulate at first, then spreading out 
laterally at the apex, and at length somewhat palmately cleft 
into 2-12 unequal, obtuse, finger-shaped branches; stem curved, 
solid, equal or somewhat tapering towards the base, bone- 
brown, sometimes swollen where attached to the substratum; 
hymenium even or but slightly venose, inferior, colored like 
the pileus; spores white, even, pyriform, tapering to the base, 
6-8 x 3-4 и. 
Fructifications 1-23 cm. high; pileus 3-15 mm. broad, 1 
mm. thick; stem 8-15 mm. long, 1-14 mm. thick. 
On rotten chunks of wood in frondose woods. Ohio. June. 
All specimens of the collection except one have the pileus 
flabelliform; in this exceptional specimen, the pileus is narrowly 
turbinate, depressed, and with the finger-shaped branches 
arranged in a circle on the margin, pl. 17 fig. 19b. This species 
makes for Craterellus the same connection between the central- 
stemmed, cup-shaped type of pileus and the flabelliform type 
that T'helephora multipartita shows in Thelephora, and that is 
common in Stereum. The hymenium of the flabelliform speci- 
mens of Craterellus palmatus is so similar to the upper surface 
of the pileus in color and consistency that one cannot readily 
distinguish between these surfaces in the dried specimens. 
For these reasons, the present species cannot be referred to 
either Skepperia or Friesula, and it is of especial interest in 
showing that Craterellus has a natural section of species with 
flabelliform pileus. Тһе spores of C. palmatus are noteworthy. 
Specimens examined:

Type: in Farlow Herb. 
Fruetifieations single, fleshy; pileus flabelliform, somewhat 
triangular, glabrous, drying a dirty pinkish buff, the margin 
somewhat irregularly lobed, crisped, and curving upward; stem 
solid, equal, flexuous, drying Natal-brown, with white myce- 
lium at the base; hymenium even, drying Isabella-color to clay- 
color; spores white, even, broadly ovoid, obtuse, 8-10 x 6-7 и.
