Hi.
In a humid place, on the ground, near Salix and Alnus, I found small mushrooms that resemble Tarzetta or Geopora. Initially, I thought these mushrooms were Tarzetta, but I couldn't identify them. I met the description of Geopora tenuis in "Note of taxony, ecology, ................. in Norway" - Schumacher The description I found there, especially the size of the spores and habitat, ideally matched my find.
For this reason, I placed them in my atlas as Geopora tenuis, although I do not quite agree with this term:

The spore size in it did not match my current concept of this species. Until now, I considered G. tenuis, collections that are presented on my website:

However, these collections have spores that are definitely narrower than Schumacher says?
As you will probably notice, both of these finds are very similar, so I would not be surprised that Tarzetta can be mistaken for Geopora. The main differences are longer and larger amount of hair and the width of the spores.
You don't think that the collection presented on the website:
http://www.grzyby-pk.pl/gat_g/gat_geopora_tenuis.php
- corresponds to the species Tarzetta sepultarioides described by Nicolas Van Vooren ??
In turn; http://www.grzyby-pk.pl/gat_g/gat_geopora_20150710.php
- should I call her G. tenuis again?
Yours sincerely
