Description in English 



of some new and of some unsatisfactorily known species 

 of Myxomycètes described in the preceding treatise 



by 



C. Raunkiær. 



Enteridium Rostrupii sp. nov. 



Æthalia irregular, lengthened, the greatest length is 4 cm., 

 consisting but of one stratum of sporangia, which are 1 mm. 

 thick. Wall of sporangium olive; the lateral wall towards ripen- 

 ing of the spores perforated by large, oval openings. Mass of 

 spores olive; the single spore rather colourless. Spores in oval 

 — ball-shaped clusters of from 5 — 25. Only the convex surface 

 warted, 11 — 12 diam. 



On fir stumps and rotten oak branches. — Autumn. Near 

 Horsens in Jutland. 



E. macrosporum, sp. nov. Tab. 2, fig. 1. 



Æthalia hemispherical, c. 2 mm. diam., at .first reddish, 

 later olive. Spores in oval — ball-shaped clusters of from 5 — 25. 

 Only the convex surface spinulose, 12 — 14 juL diam. 



On rotten fir branches. — Autumn. Near Copenhagen. 



This species I have only found once and then but in a very 

 few specimens. It seems to be especially different from the 

 other species of Enteridium in the dimention of spores and the 

 particularly developed sculptur of tlieir convex surface.
