Lycogala.
I can find no detailed description of the genus as searches almost all just list Lycogala epidendrum.
The best I could find is from http://zipcodezoo.com/Key/Fungi/Lycogala_Genus.asp
“A genus of cellular slime moulds, fruiting bodies (aethalia )small to large. Pseudocapillitium usually attached to the inner cortex and composed of branched air-filled tubules which are convoluted and/or decorated with warts or spines ( Photo http://www.myxoweb.com/capill.htm ). Spores thin-walled and banded-reticulate, at least in part.”
The number of species varies from 1 or 6 to many with more being described.
