Naming

''Mycena tenerrima'' has a swollen or disk-like stipe base; also, the stipe surface is more densely hairy with caulocystida. ''Mycena stylobates'' has a pruinose stipe that arises from a basal disc, but the cap is up to 10 mm and lacks white granules. White ''Hemimycena'' species lack granules and all have inamyloid spores.
