White apos on pine cone

Stefan Jakobsson, 09-11-2022 00:03

On a cone of pine on the ground in a dry place there were a few white convex apos, up to 800 µm wide. The apos are subsessile and seem to have an almost invisible subiculum. The asci are 68-96 x 8.1-10.9 µm, with croziers, negative IKI reaction if not pretreated with KOH and even then only faintly blue. The spores are 37-44 x 1.6-2.1 µm, with 3-8 septa. The paraphyses are interesting, branched above and often inflated at the apex to 1.8-6.0 µm. External view of the excipulum seems to be globosa.

Even a genus is difficult to find for this one. Ideas, anybody?

Re : White apos on pine cone

This reminds me of Pseudohelotium pineti but it could also be an Arachnopeziza.
