LiCEA 205 



Type locality: Scotland. 



Habitat: On the inner, thin layers of bark. 



Distribution: New York. 



Illustration: Lister, Mycetozoa ed. 3. pi. 219, figs. e-g. 



This species was collected on two occasions on the inner layers 

 of bark, from the same tree, associated with L. hiforis. The 

 brown color of the sporangia, and the colorless, almost smooth 

 spores distinguish it from L. minima. 



3. Licea pusilla Schrad. Nov. Gen. PI. 19. 1797. 



Plasmodium watery-drab, or dull yellowish (Lister). Sopran- 

 gia scattered, sessile, hemispherical or pulvinate, 0.6 to 1 mm. 

 diam., dark purple-brown, glossy on the inner side, dehiscing in 

 irregular lobes; sporangial wall cartilaginous, chestnut-brown, 

 often with deposits of dark refuse matter, the margins of the 

 lobes usually crenate and undulate, dotted with prominent warts 

 1-2 /i diam. Spores olive-brown, 13-20 n diam., closely warted, 

 the wall thinner on one side. 



Type locality : Germany. 



Habitat: On dead wood. 



Distribution: Pennsylvania. 



Illustration: Lister, Mycetozoa ed. 3. pi. 149, figs. a-c. 



This species is similar, superficially, to L. minima, differing in 

 the much larger average size of the sporangia, and the much 

 larger spores, which latter is the important character. It can 

 be distinguished also by the appearance of the dehiscence ridges, 

 which are usually crenate or undulate, although occasionally 

 straight in some sporangia of a colony. The only collection here, 

 personally made in Pike County, Pennsylvania, has spores 15-17 /i 

 diam. Other records from North America are not included, as 

 there are circumstances connected therewith which make the 

 identifications doubtful. 



4. Licea flexuosa Pers. Syn. Meth. Fung. 197. 1801. 

 Licea variabilis (?) Schrad. Nov. Gen. PI. 18. 1797. 



Plasmodium dull yellow or rose-colored (Lister). Sporangia 

 scattered, pulvinate, depressed, more often forming straight, 

 curved or branching plasmodiocarps, 1 to 6 mm. long, either yel- 

 lowish brown and glossy, or dark brown and opaque when an outer 

 layer of refuse matter is present; sporangial wall cartilaginous, 

 translucent, pale purplish brown, usually more or less overlaid
