KEY TO THE SPECIES OF LICEA. 
A. Spores spinulose : — 
Sporangia forming elongate plasmodiocarps, spores 11 to 14 /x. 
1. L.Jlexuosa 
Sporangia subglobose, spores 9 to 11 /a. 2. L. minima 
B. Spores smooth, 16 to 20 /a. 3. L. jjiosilla 
1. L. flexuosa Pers., Syn. Fung., p. 197 (1801). Plasmodium 
dull yellow. Sporangia pulvinate depressed, or forming elongated 
plasmodiocarps, scattered, 2 to 4 mm. long, opaque, dark brown, 
dehiscing irregularly; sporangium-wall of two closely combined 
layers, the outer opaque from granular deposits of refuse matter, 
the inner cartilaginous, translucent, olive-brown. Spores pale 
olive-brown, spinulose, 11 to 14 /a diam. — Host., Mon., p. 218.

Plate LVII., A. — a. plasmodiocarp, x 20; h. fragmeut of sporangium- 
wall and spores, x 280 ; c. spore, x 600 (Germany). 
The spores in this species are free, and thicker and rougher on one 
side. There is a specimen from Capt. Oarmichael, Appin, Argyle 
(K. 1670), named by Berkeley Licea flexuosa, and by Rostafinski 
EntericUum olivaceum (Mon., App., p. 30), which is a simple plasmodio- 
carp form without capillitium, resembling L. Jlexuosa, but the spores 
are in clusters of 6 to 8 ; it holds an intermediate position between the 
two species, which appear to be closely allied ; specimens of typical 
sethaUoid Enteridiwn olivaceum are occasionally found having free 
spores.

2. L. minima Fr.,- Syst. Myc, iii., p. 199 (1829). Plasmodium 
yellow (teste Rex). Sporangia hemispherical on a broad base, 
depressed, scattered, 0'2 to 0"5 mm, diam., brown or nearly black, 
dehiscing in lobes; sporangium-wall cartilaginous, opaque, dark 
brown, the margin of the lobes dotted with minute granules 
1 to 2 ju, diam. Spores olivaceous-brown, thicker on one side, 
spinulose, 9 to 11 diam. — Tuhulina minima Mass., Mon., p. 36.
