which is dark brown in color and which spreads to several inches in 
circumference. The presence of a central columella, connecting with 
the walls by lateral threads, is the constant feature which distinguishes 
this species from Zubulina fragiformis. 
PHYSARUM LEUCOPUS Link, which has been recorded in this country 
for the western States only, was found in Middlebury, growing on a 
decayed log. The ball-like sporangia, which have membranous walls 
beset with lime, are supported on smooth white stalks also containing 
lime. The capillitium consists of large lime knots connected by 
slender hyaline threads. The snowy whiteness of the stalks is the 
means of separating this species from ZP. nutans., while the lax capilli- 
tium and the large knots containing large lime granules distinguish 
this species from 2. globuliferum. 
BADHAMIA MAGNA Pk., a purely American species and of unusual 
occurrence, has been found twice in Vermont. The gray, globose 
sporangia with wrinkled iridescent walls are raised on clustered, yellow 
stalks. The capillitium is formed of threads or bands connected by 
angular expansions having small granular deposits of lime. Badhamia 
hyalina is sometimes confused with this species because of the similar- 
ity of capillitium structure, but by comparing the large warted and 
clustered spores of this species with the spores of B. magna, which are 
smaller and scattered, the difficulty is cleared. 
PHYSARUM CINEREUM Pers. is not an unusual species, yet it is worthy 
of note because its capillitium shows Badhamia characteristics. The 
sporangia are sessile and irregular in shape, with lime granules in the 
membranous walls. ‘The capillitium consists of branching bands and 
large white lime knots with a very few hyaline threads. These bands 
were so densely charged with lime that the species seemed to be B. 
panicea, but the presence of a few hyaline threads and the size of the 
small light-colored spores marked the species as P. cinereum. A 
specimen from the collection was submitted to Mr. Arthur Lister for 
his opinion, and he regards it as an undoubted but very remarkable 
form of P. cinereum Pers. 
FULIGO OCHRACEA Pk. is another American species seldom found. 
The sporangia are very closely interwoven to form an aethalium with 
a gray cortex containing lime. ‘The capillitium consists of very short 
hyaline threads connecting large yellow lime knots. The shortness of 
these threads together with the large spores are the only points of 
difference between this species and the closely allied Fudigo septica.
