The inner meshes equal and of ordinary width; on the
surface of the capillitium, on the contrary, groups of very small
and single layers succeed each other alternately.

Arcyria ferruginea, Rost. (figs. 250—233).
Sporangia globose or ovate, sometimes deformed, stipitate,
dull vermilion or rusty-red, sometimes pale reddish-pink; stem
thin, length variable, usually short, filled with large cells; mass
of capillitium and spores brick-red, brownish, sometimes ochraceous
; capillitium becoming elastically protruded, threads combined
to form a dense, irregular network, more or less acutely
triangular, one side with parallel projecting ridges, the two others
vÁth a fine, irregular network; spores globose, smooth, 9— 11 g
diameter.

Distinguished amongst the red species of Arcyria by the
portion of the capillitium threads not occupied by the prominent
ridges being ornamented with a delicate network of
slightly raised lines.

Arcyria incarnata, Rost.
Sporangia crowded, ovate or sub-globose, stem very short or
absent, wall reddish, often with a brown or yellow tin g e ; mass
of spores and capillitium flesh-colour, rosy, or reddish-brown,
sometimes ochraceous; capillitium attached to the apex of stem
wall, and with very few attachments to basal portion of thin,
sporangial wall, threads combined to form a dense, elastically
protruding network, with many free, flattened, or swollen spinose
tips, markings in the form Of half-rings or spines, or a mixture
of the two arranged in a loose spiral, and mixed with small,
spinose warts, there are frequent swellings in the length of the
threads; spores globose, smooth, pinkish or tinged with ochre,
6— 8 g diameter.

f e ic c .—Fuckel, Fung. Rhen., 1442.
On rotten wood and bark. Britain (Lyndhurst, Kew, Kings
Cliffe, Norths, Carlisle, Aboyne, N. B .); Europe; United States ,
India; Ceylon.
Usually crowded, sub-sessile, 1'5—2 mm. high. The wall ot
the sporangium is thinner, and the permanent base little or
not a t all longitudinally ribbed ; the capillitium threads are
o-enorally round, hut sometimes compressed. Closely allied to
A. punicca, of which the present is perhaps only a variety;
intermediate stages between the two are not wanting.
