Minute whitsh apos on Picea wood
Stefan Jakobsson, 28-03-2023 01:34
On wood of a still fairly hard trunk of spruce I found some scattered whitish apothecia of up 400 µm diametre; no stipe but attached at a fairly narrow point. A very thin subiculum is present on the surface of the wood.

The excipulum looks like t. oblita and is hard to separate under the cover slip; no dextrinoid reactions. No disinct hairs. The asci are 36-50 × 4.5-6.4 µm, with a reddish brown ascal ring in IKI, with croziers. The parafyses are slightly clavate and covered with some kind of incrustations at the apex. The incrustations dissolve in MLZ. The spores are ±ellipsoid, without visible content, 5.2-6.6 × 2.5-2.9 µm. The most basal spores are tapering below.


I have no good idea where to place this. Any ideas are wellcome!

Compare the white form of Durella suecica.

That is it! Thank you!

The species (and genus) is surprisingly variable. The subiculum could fit the relatedness to Arachnopeziza.
