KEY TO THE SPECIES OF LICEA. 



A. Spores spinulose : — 



Sporangia forming elongate plasmodiocarps, spores 11 to 14 



1. L.flexuo 



Sporangia subglobose, spores 9 to 11 /u. 2. L. minin 



B. Spores smooth, 16 to 20 /*. 3. L. pusit 



1. L. flexuosa Pers., Syn. Fung., p. 197 (1801). Plasmodiu 

 dull yellow. Sporangia pulvinate depressed, or forming elongati 

 plasmodiocarps, scattered, 2 to 4 mm. long, opaque, dark brow 

 dehiscing irregularly; sporangium-wall of two closely combini 

 layers, the outer opaque from granular deposits of refuse matte 

 the inner cartilaginous, translucent, olive-brown. Spores pa 

 olive-brown, spinulose, 11 to 14 /i diam. — Rost., JVlon., p. 21

The spores in this species are free, and thicker and rougher on o: 

 side. There is a specimen from Capt. Carmichael, Appin, Argy 

 (K. 1670), named by Berkeley Licea flexuosa, and by Rostaflns 

 Enteridium olivaceum (Mon., App., p. 30), which is a simple plasmddi 

 carp form without capillitium, resembling L. flexuosa, but the spor 

 are in clusters of 6 to 8 ; it holds an intermediate position between tl 

 two species, which appear to be closely allied ; specimens of typic 

 sethahoid Enteridium olivaceum are occasionally found.having.fr

2. L. minima Fr., Syst. Myc, iii., p. 199 (1829). Plasmodiu 

 yellow (teste Rex). Sporangia hemispherical on a broad bas 

 depressed, scattered, 0'2 to 0-5 mm. diam., brown or nearly blac 

 dehiscing in lobes; sporangium-wall cartilaginous, opaque, da] 

 brown, the margin of the lobes dotted with minute granul
