Scattered over the leaves and quite superficial, attached by a few hyaline
creeping threads. Peritheciaglobose, beset with very long radiating, rigid,
somewhat pellucid, articulated bristles, which are black to the naked eye,
but purplish-brown under the microscope ; when young their apices are often
swollen. Asci rather short, clavate. Sporidia biseriate, oblong-elliptic,
about four times as long as broad.
The perithecia are much larger than iu V. ckoetomium, the hairs are longer,
pellucid, and not opaque ; asci clavate, and not fusiform, and the uniseptate
sporidia are shorter.
