Java. Might as well be called Diderma echinocephalum, one would think. Structure is that of Leangium. The striking character is a surface modification of the outer peridium, according to the description.

Order II

STEMONITALES

Capillitium present, thread-like, arising in typical cases from a well-developed columella; spores in mass, black or violet-brown, more rarely ferruginous.

Key to the Families of Stemonitales

A. Fructification æthalioid, capillitium poorly defined; columella rudimentary or noneAmaurochætaceæ
B. Fructification of distinct sporangia, capillitium well defined; the columella generally prominent, long and abundantly branched throughoutStemonitaceæ
C. Sporangia distinct; capillitium developed chiefly or only, from the summit of the columellaLamprodermaceæ

A. AMAUROCHÆTACEÆ

Fructification æthalioid, an inch or two in diameter, in form varying with the habitat and place; capillitium dendroid, consisting of rather stout branches which rise irregularly more or less vertically from the hypothallus, branch repeatedly, often anastomose to form a network, especially toward the periphery; spores black.
