An authentic specimen from Curtis (B. M. 994) has too little left 
for identification, yet some spores and a fragment of sporangium 
which were scraped off were identical with a good typical specimen in 
Sti-assb. Herb., sent by Pi-of . Farlow from Curtis's original gathering. 
In the type specimens of both Badhamia Alexandrow'/crdi Rost. and 
Didymium reticulatum Berk. & Br. (B. M. 574), the sporangia are 
slender, rugose, yellow plasmodiocarps, having Badhamia-like capillitium 
with few hyaline threads, the spores 10 to 12 /x diam. ; they closely 
resemble the common North American form which appears in the 
Schweinitzian collection under the name of Cienkoioskki reticulata 
Rost. In these American specimens the capillitium has large, 
branching, pale-yellow lime-knots sparingly connected by hyaline 
threads. Spores 9 to 11 ^ diam. Badhamia. chrysotricha Host. difPers 
from the last only in the more completely Badhamia-like capillitium 
and the rather larger spores, measuring 11 to 13 /x. 
Hah. The original specimen was found on the trunk of a living oak. 
It is found also on dead wood, moss, etc. — Poland (Strassb. Herb, 
and L:B.M.5 slide) ; Ceylon ( B. M. 574) ; Pennsylvania (L:B.M.5) : 
S. Carolina (B. M. 994).

Plasmodium? Sporangia globose, 1 mm. diam., violet-grey, the 
sni'face wrinkled, iridescent, clustered on long membranous 
yellowish slender branching stalks, 4 mm. long or more ; 
sporangium-wall with scanty deposits of lime. Columella none. 
Capillitium as in B. hyalina Berk. Spores purplish-black, darker 
and minutely spinulose on one side, almost smooth, not clustered,

This species has been recorded only from America, and is represented 
in the collection by a mounting from Peck's type ; it is nearly allied 
to B. hyalina Berk.
