124 A Monograph of the Myxogastres. 



containing numerous cell-like aggregations of protoplasm, while 

 the inner portion gives origin to the tubes of the capillitium 

 which originate from the cell-like masses of protoplasm. 



Rostannski's generic diagnosis of Dermodium is altogether 

 misleading, inasmuch as it implies that we are dealing with a 

 single sporangium, whereas in Rostannski's own specimens the 

 plasmodiocarp structure is distinct. Furthermore it is very 

 doubtful as to whether the present species is anything more 

 than Lycogala cpidendrum. It is certain that Lycogala atropur- 

 pureum, B. and Br., and Lycogala nitidum, B. and Br., referred 

 to the present species by Rostafinski, both belong to Lycogala 

 epidendricm.

 bright chestnut-brown, or greyish-umber ; mass of spores greyish- 

 umber or with a flesh-coloured tinge; tubes of capillitium

 or ivith indistinctly raised bands, sparingly branched ; spores 

 globose, very minutely wartcd, 5 /x diameter.

A large species, usually solitary, distinguished from L. cpi-

 thinner tubes and rudimentary ornamentation.
