Dear collegues,today I found a rich collection of
Mollisia on Vaccinium

There were plenty of these Mollisias growing on dead stems of Vaccinium myrtillus in a boggy forest.
The yellow KOH-reaction was quite vivid and lasted for a while.
Spore measurements: 9.6 - 12.4 × 2.2 - 2.6 µm.
Do you think this might pass as Mollisia albogrisea?

Re : Mollisia on Vaccinium
Or maybe M. fusca rather? This did have a brown subiculum as well.

Re : Mollisia on Vaccinium
The subiculum would be worth checking, I see in M. fusca rather broad and thick-walled hyphae (4-5 µm, wall 1-1.5 µm). The oil content in the spores is a bit high for fusca.
M. albogrisea has a low spore oil content and apos are paler and often grow on bark.

Re : Mollisia on Vaccinium
I checked the subiculum closer, and under the stereo microscope there was a plentiful, woolly mat of it. My measurements were 3.4 - 4.9 µm for the width and 1 - 1.4 µm for the thickness of the wall. So, a pretty good fit!

Re : Mollisia on Vaccinium
Yes, they are 3-5 µm and thick-walled. M. fusca is at least a probability.
