Delitschia/Lojkania? on wood

Tomaz Vucko, 25-01-2026 23:23

Hello! I found this species that resembles Delitschia on wood in the proximity of a swampy area (Alnus, Populus, Prunus, Salix...). In a quick walkthrough through some keys I didn't find some good matches. Does someone have an idea of what could it be?

Spore measurements are:
(21) 21.8 - 25.9 (27.2) × (8.4) 9.2 - 9.9 (10.1) µm
Q = (2.1) 2.3 - 2.7 (2.8) ; N = 53
Me = 23.9 × 9.6 µm ; Qe = 2.5

Edit:
After a bit of reading I now also start to suspect Lojkania.

Lokjana melasperma was my idea, too.Very nice photos, good job.
Molecular data should help to know if this species is a "true" Delitschia.

Hi Tomaz,
good work,
I agree with Alain, I also repeatedly came across this fungus, likewise in aquatic environments and Lojkania melasperma (Cooke) Barr is so far the best name available.
I saw a LSU sequence showing it nested in or close to Delitschia, the closest branch being D. chaetomioides.
This group badly needs to be updated.
Cheers,
Jacques

Re : Delitschia/Lojkania? on wood

Thank you Alain and Jacques.

Yes, this was the species I had in thought and it seems to fit the best.
Sorry for a bit late reply.

Best regards,
Tomaz.
