Pyreno on hare dung

Juuso Äikäs, 07-08-2023 19:32

These little black pyrenos were growing on hare droppings in an open, grassy area.

The asci are 8-spored, IKI negative. The spores have a gelatinous sheath and measure 27.0 - 31 × 17 - 19.5 µm.

Anybody familiar with this?

Re : Pyreno on hare dung

Hi Juuso
Check it in the genus Sordaria.

Re : Pyreno on hare dung

Thanks Enrique, I checked Finnish findings of Sordaria, and the species S. superba seems to fit in terms of substrate and microscopy. The spores ought to get darker with age.

Re : Pyreno on hare dung

Yes. They are very immature yet.
