Hymenoscyphus with sheaths
Khomenko Igor, 10-01-2021 17:40
Khomenko IgorHi,
I have this Hymenoscyphus that I want to call H. macroguttatus, but spores with sheaths.

https://inaturalist.ca/observations/54700515

On a small herb twig on the ground in a wet area.
Ascospores 19-21x3.7-4.5um.
Asci IKI+b, croziers(+), 69-77x7.6-8.2um
Paraphyses cylindrical 2-2.2um width, septated with a fork at the base with large VBs in the top segments.
The medullary excipulum has ?intricata textura, very gelatinous and with plenty of crystals.

Best regards,Igor

Re : Hymenoscyphus with sheaths
Hi Igor

such sheaths are very common in Helotiales.

Loks like an Ombrophila indeed. In my O. rivulorum folder I have comparable finds, some almost attaining spore length of yours.
