frequent misidentification

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.”

It looks as though the differentiation between M. candidus and T. nigripes is a matter of some pretty specific microscopy. Anyone know of any surefire macroscopic characteristics which distinguish the two?

EDIT: was going to add this comment to all M. candidus and T. nigripes, but I thought that might be a bit annoying.
