height and 0.3-0.5 mm. in thickness. In both specimens of P. 
pulcherripes above referred to, the stalks are slender and bulging 
with globular, red masses of plasmodic material, i8;u, in diameter, 
largely replacing the usual lime. 
“ Physarum vermiculare Schw. Salem. Herb. Schw.” 
This is a fairly good specimen of typical Perichaena vermicu- 
laris (Schw.) Rost. 
“(1972) Diderma pallidum B. & C. Pine leaves and straw 
on the ground. Aug. 1848. Santee Canal, S. C. Ravenel (788).” 
Berkeley (Grevillea, 2: 52, 1873) referred this specimen to 
“ Angioridium valvatiim Fr.,” a combination which apparently 
never existed. What Fries wrote (Index Syst. Myc., p. 51) was 
"Angioridium sinuosum Gr. {Diderm, valvat.l Phys. sin.?).” 
Berkeley {1. c.) also wrote " Diderma pallidum B. & C.” in connec- 
tion with this specimen, but since he added no description, both 
names are nomina nuda, and Physarum bogoriense Racib. takes 
precedence. Moreover, the specimen numbered 1972 in the Berke- 
ley herbarium differs essentially from the common Angioridium 
sinuosum of Greville, according to Miss Lister (Monog., Ed. 2, 
p. 78). The scanty remains of the corresponding specimen in the 
Curtis herbarium throw no further light on the subject except in 
so far as the pale violet-brown, almost smooth spores, measuring 
9-10/A diam., differ from those of P. sinuosum. 
“Physarum decipiens B. & C. (1333) ad Trunc. Querc. viv. 
Aug : Sept. Society Hill ; S. C.” 
This is a comparatively fine specimen consisting of a number 
of globose or elongated sporangia, 0.5 mm. in diam., sessile, ru- 
gose, reddish-orange ; capillitium of yellow branching lime-knots 
with no connecting threads ; spores free, pale umber, minutely 
spinulose, 13-15 /a diam. It is, of course, Badhamia decipiens 
(Curt.) Berk. 
“ Badhamia papaveracea cort ; Quercus. Aiken, S. C. Rave- 
nel (1768).” 
This specimen is a co-type and, though somewhat scanty, shows 
admirably the characters distinguishing it from B. capsulifera, 
i. e., the short, stout, brown stalks on which the sporangia are borne
