Arcyria (Erstedtii, Rost.

than sporangium, firm, erect; like the sporangium, dirty brown;
mass of capillitium and spores brown, often with a red tinge;
capillitium forming a rather dense net, threads cylindrical,
3— 5 g diameter, with scattered, elliptical, swollen portions, sparingly
and equcdly covered with slender spines of various lengths;
spores smooth, 8— 10 p- diameter.

On wood. Britain (Burnham Beeches, Bucks); Denmark;

Characterized by the net, without free arms, having its
threads swollen at intervals, and sparingly and equally covered
with slender spines of variable length, the longest about equal

Arcyria umhrina, Schum.
Sporangia single or gregarious, on a thin, shining hypothallus,
ovate, stipitate. Receptacle on the inner side provided with
a network of delicate thickenings. Stem brownish-black, longer
than the sporangium. After dehiscence of the sporangium the
capillitium enlarges itself but slightly. Capillitium and the
mass of spores ochre-hrown. Tubes of net of the capillitium
with thickenings in the form of half-rings encircling the thread
in a spiral, without regard to the thickenings 2'5—3 g broad.
Spores smooth, 5—7 g diameter.
