220 Mycetozoa of North America 



1. Liceopsis lobata (Lister) Torrend, Bull. Soc. Portug. Sc. Nat. 

 2:63. 1908. 



Reticularia lobata Lister, Mycetozoa 161. 1894. (N. Y. B. G. no. 11285, 

 authentic material.) 



Plasmodium watery white (Lister). Sporangia closely clus- 

 tered, usually sessile, angled by mutual pressure, rarely solitary 

 or stalked, subglobose, 0.4 to 0.7 mm. diam., rusty brown, shining 

 iridescent, sometimes confluent to form a flat or globose aetha- 

 lium ; sporangial walls membranous, smooth. Capillitium scanty, 

 consisting of slender, rusty brown, branching and anastomosing 

 threads and strands with thin, membranous expansions. Spores 

 subglobose or turbinate, rusty brown, sharply and closely reticu- 

 late on two thirds of their surface, faintly and loosely reticulate 

 on the remaining third, 6-10 /x diam. 



Type locality: Essex, England. 



Habitat: On dead wood. 



Distribution: *Oregon, ^Washington. 



Illustration: Lister, Mycetozoa ed. 3. pi. 154, figs. d-f. 



This species has been reported from two western states, and 

 little is known about it from American gatherings. It is related 

 to Enteridium Rozeanum and Reticularia Lycoperdon. 



Family V. LYCOGALACEAE 



Sporangia forming an aethalium; pseudo-capillitium consisting 

 of smooth or wrinkled branching colorless tubes. 



A SINGLE GENUS. 



Genus 37. LYCOGALA Micheli; Adanson, Fam. PI. 2: 7. 

 1763. 



Aethalium subglobose or conical, with a cortex of two or more 

 closely combined layers of different structure; the outer layer has 

 large cell-like vesicles, which are either embedded or superficial, 

 and is traversed by interlacing tubular threads; these pierce the 

 homogeneous inner layer, and are continuous with the tubes of 

 the pseudo-capillitium; the latter are gray or colorless, wrinkled 

 or nearly smooth. 



Type species: Lycoperdon epidendrum L. 



Aethalia large, over 2 cm., cortex smooth or areolate. L L. flavo-fuscum 



Aethalia smaller, less than 2 cm., cortex warted. 



Aethalia subglobose. 2. L. epidendrum 



Aethalia conical. 3. L. conicum
