Recognized by sight: Small to medium fruiting body; growing on decaying wood; clustered; subtropical/tropical; widely-spaced, intervenose-to-anastomose gills; velutinous, snowy black stipe gradually changing to cap color toward apex. Given the vast dispersal of this species and its tendency for considerable variation, I wouldn’t be surprised if this were a complex as opposed to a single species.

Quoted from http://www.mycologia.org/cgi/content/full/97/3/667:

“…herbarium-deposited North American material of M. candidus often have been misdetermined as Tetrapyrgos nigripes (Desjardin pers obs). We reserve judgment on whether Marasmiellus sect. Candidi belongs to a redefined Tetrapyrgos or represents a distinct lineage until further species of the group are added to the analyses.”
