3. L. conicum Pers., Syn., i., p. 159 (1801). Plasmodium 
rose-red, in rotten wood (teste Dr. Eex). ^thalia conical, sessile 
on a broad base, crowded or scattered, 1-5 to 3 mm. high, 0-8 
to 1-5 mm. broad, sometimes subglobose, yellow-brown ; the dark 
confluent superficial vesicles forming spots or a broken reticula- 
tion, chiefly on the upper part ; cortex thin, of two closely com- 
bined layers, the outer traversed by flattened threads 2 to 10 
broad, either loosely interlacing, or more often nearly parallel 
in a single series, and separated by intervals of 2 to 20 /a, piercing 
the membranous inner layer and continuous with the capillitium. 
Capillitium of simple, rarely branching, olivaceous-grey threads, 
3 jjL diam., or varying from 2 to 7 /a, faintly and minutely wrinkled, 
with clavate or obtuse ends. Spores, in mass, yellowish-gi-ey or 
ochraceous, minutely reticulated over the greater part of the 
surface, 4 to 5 /a daam. — Fries, Syst. Myc, iii., p. 82 ; Mass., 
Mon., p. 123. Dermodium conicum Rost., Mon., p. 284. 
Plate LXXVI., A.— a. aethalia, x 20 ; b. part of cortex ; (1) outer 
membranous layer, bearing on the surface irregularly shaped vesicles con- 
taining dark granular matter, traversed by empty flattened tubes, having 
a somewhat parallel arrangement ; (2) homogeneous inner layer, perforated 
by the narrow capillitium tubes, x 180 ; c. part of capilUtium tube, and 
spores, X 600 (Ohio, U.S.A.). 
This description is taken from specimens received from Dr. Rex 
under the name of Derviodium conicum^ and from Mr. Morgan under the 
name of Lycogala conicum ; they were gathered in Fairmount Park, 
Philadelphia, and at Preston, Ohio. They differ from L, mmiatum in 
the uniformly small size and more or less conical shape, in the scanty 
seldom branching somewhat parallel threads in the thin outer layer 
of the cortex, and in the almost simple threads of the capillitium : 
very similar structure is met with, however, in minute thin-walled 
aethalia of L. miniatum, showing the close alliance of the two species ; 
but such small aethalia of L. miniatum are usually found in company 
with others of more ordinary dimensions, and differ in shape and in 
the arrangement of the warts from the American specimens. The 
type specimen of L. nitidum Berk. & Br., from Ceylon (K. 1729), is 
referred to by Rostafinski as being Dermodium conicum (Mon., App., 
p. 37) ; the cortex is thin, and traversed by broad and narrow threads, 
more interwoven than in the specimens from America ; but the aethalia 
are hard and immature, and are valueless in the determination of 
specific characters.
