Hemimycena or Marasmiellus

The underside looks a lot like Marasmiellus candidus, but my mushrooms are smaller (there is about 20 of them and the largest is about 5 mm) and their spores are definitely of a different shape and size.

In “Agaricales …”, Singer says that the stem of Marasmiellus is “insititious or subinsititious, rarely with a fibrillose-tomentose basal muycelium but then the epicutis with a distinct Rameales-structure and/or stipe eccentric to lateral”. I scoped the cap surface and didn’t see anything standing out. Unless I missed the Rameales-structure, it seems that Hemimycena is a better guess than Marasmiellus.
