tates against this view, and the character of the spores in the 
specimen under consideration supports it. 
“(5191) Physarum chrysotrichum B. & C. lign. putr. Aut. 
1854 Ala. Peters (704).” 
The label reads “ chrysostictum,” evidently a clerical error. In 
the original description of the species (Grevillea, 2: 66. 1873) 
the specimen number is given as 5091, but in Curtis’ original MS. 
list it is 5191. Lister’s reference of this species to Badhamia 
decipiens (Curt.) Berk, seems based on fairly sufficient evidence. 
The Curtis specimen shows nothing but the basal portions of a 
number of sessile, golden-yellow sporangia and a few violet- 
brown, minutely spinulose spores, 1 1 /a in diameter, or slightly 
smaller. 
“Physarum cupripes B. & R. Ravenel (1645) & Peters 
(1157)” 
Again by an error, the label reads " cupriceps.” Both speci- 
mens are in wretched condition. The single sporangium found 
shows a very delicate capillitium with scanty and small, yellowish 
lime-knots, and violet-brown spores, almost smooth, and measur- 
ing 8/jl diam. A very fine specimen is to be found in Ravenel’s 
Fung. Car. Exsicc., Ease. Ill, No. 76, under the name P. cupri- 
ceps Berk. & Rav. Both Lister and Macbride correctly refer this 
species to Physarum flavicomum Berk. 
“(6072) Physarum petersii B. & C. Ala. superiore, Peters 
(982).’’ 
This specimen, referable to P. pulcherripes Pk., is in compara- 
tively good condition, though the sporangia are crushed down 
upon the soft substratum. Careful treatment exhibits a columella 
not peg-like, such as is usually seen in the " globuliferum” group, 
but varying from broadly conical to subglobose and giving rise to 
the columella from all parts of its surface, very much as in Didy- 
mium nigripes (Lk.) Fr. var. eximium (Pk.) List. The speci- 
men of P. pulcherripes distributed in Ellis & Everhart, N. A. F., 
No. 3300, shows the same form of columella, and even in the 
case of typical P. globuliferum (Ell. & Ev., N. A. E., No. 1120) 
the columellae are large and columnar, measuring 0.8-1. 5 mm. in
