raised lands in the form of rings, '4—'7 g high, coinbiued into
a net with free, more or less swollen tips; spores globose, 10 g
thick, with raised hands forming a polygonal network.

On wood. Germany.
Wigand describes the spores as areolate on the surface, but
judging from his figure of a spore, mag. 720 diameters, it appears
that the areolation is due to raised bands combined to form a
polygonal network.
Ophiotheca paUida, B. and Curt.
Sporangia flexuous, pale ; threads of capillitium yellow, nodulose,
minutely eehinulate; spores globose, '0004 inch in diameter
( = about 11 g).

The flood are very irregular in outline, and have far shorter
processes than the other two species. [0. chrysosperma and C.
Wrightii] (M. J. B.)
There is no specimen in the Berkeley Herbarium.

Sporangia stipitate, sessile, or aethalioid, dehiscing irregularly
or by the disappearance of the upper evanescent portion of the
wall; capillitium combined into a net, which is attached
at numerous points to the wall of the sporangium; spores
globose.

p. 433; Cooke, Brit. Myx., p. 74; Zopf, p. 170.
Very closely allied to Arcyria; in fact the only important
point of difference consists in the present genus having the
capillitium attached by arms at numerous points to the wall
of the capillitium, hence it is not protruded elastically when
mature as an aid in spore dispersion, a function performed by
the elastic capillitium in some species of Arcyria, but not all,
as in several species belonging to the last-named genus, the
capillitium is in many places attached to the wall, as m A.
chrysospora, A. pallidula, &o. In Areyria the markings on the
capillitium threads are generally more developed than m
Lachnobolus.

Lachnobolus glohosus, Rost. (fig. 204).
Sporangia globose, stipitate, lower half of sporangial wall
stout, persistent, upper half very thin, evanescent, yellow, becoming
whitish; stem about equal in length to sporangium, straight,
coloured like the sporangium, filled with Urge irregular angular
cells; mass of capillitium and spores colour of ground ginger;
capillitium dense, combined into an irregular network, attached
at many points to persistent portion of sporangium, threads
varying from 3— 6 g hmsA, closely covered u'ith minute warts;
capillitium not elastic; spores at first suh-angular from mutual
pressure, then becoming globose, hut the thick wall remains
slightly thickened at the angles, hence looking as if furnished
with a few rudimentary warts, 6—7 g diameter.
