Tatraea dumbirensis?

Stefan Jakobsson, 13-07-2020 13:57

Here a 5 mm wide fungus growing on a decidious(?) stick in a dense thicket. Everything matches Tatraea dumbirensis well as far as I can see - execpt for the spore width. The spores are

(15.5) 16.8 - 19.5 (22.1) × (4.6) 4.9 - 5.5 (5.7) µm
Q = (2.72) 3.06 - 4.30 (4.81) ; N = 34
Me = 18.01 × 5.23 µm ; Qe = 3.47

Is this just a narrow spored Tatraea dumbirensis or something related?

Re : Tatraea dumbirensis?

In fact, and it reminds me of T. macrospora from N-America. But there the spores are much longer.

At the moment I have no other suggestion, but one must carefully compare species in Phaeohelotium.
