Plate LXXV., A— a. fethalium, natural size ; J. reticulated surface of 
cortex, X 20 ; c. vertical section of cortex; (1) outer layer composed of 
interwoven, empty, flattened tubes ; (2) vesicles containing yellow or reddish- 
yellow matter, with the interspaces between them traversed hj tubular 
processes, which are more or less continuous with the capillitium ; (3) 
homogeneous inner layer, perforated by the capillitium, x 80 ; d. capiUitium 
consisting of empty tubes, occasionally containing spores in the rounded 
ends and in limited spaces in the continuity of the tubes, x 80 ; e. part of 
capillitium tube, showing the papillose sm-face, x 600 ; /. spores, showing 
unequally distributed reticulation, x 600 (N. America). 
American specimens received from Dr. Eex and Prof. Macbride 
are identical in structure with those in the Strassburg Herbarium.

2. L. miniatum Pers., in Rbmer, N. Mag. Bot., i., p. 87 (1794). 
Plasmodium rose-red, in rotten wood. Sporangia subglobose, 
sessile, crovpded or scattered, 2 mm. to 1 cm. diam., pinldsh-grey, 
yellovtdsh-brown or red-brown, minutely warted ; cortex varying 
in thickness, with superficial vesicles. Capillitium arising from 
all parts of the inner side of the cortex in loosely branching and 
anastomosing, thin-walled tubes, varying from 3 to 20 /a diam., 
more or less wriukled, vnth numerous free branches, clavate or 
rounded at the ends ; mass of capillitium and spores pinkish grey. 
Spores almost colourless, closely reticulated over the greater part 
of the surface, the remaining part marked with a loose reticula- 
tion, or with short raised lines and warts, 5 to 7 fjb diam. — ISTees,

Plate LXXV., B. — a. sporangia, natural size ; &. surface of cortex, warted 
with vesicles, x 20 ; c. vertical section of cortex ; (1) upper layer contain- 
ing interwoven thick-walled tubes, and bearing on the surface simple or 
compound vesicles ; (2) homogeneous inner layer, perforated by the capilli- 
tium, X SO ; d. capillitium, consisting of empty tubes, rugose with ridges 
and folds, x 180 ; e. part of capillitium tube, and spores, x 600 (England). 
In smaU sethalia the cortex is usually thin, the interlacing threads 
in the outer layer narrow and scanty, and the homogeneous inner layer 
membranous; in larger aethalia the outer layer is often 40 /a thick, and the 
interlacing threads broad and abundant, with gelatinous outer walls 
5 to 10 /X thick : while the homogeneous inner layer sometimes exceeds 
50 /X in thickness.
