Hymenoscyphus on eucalyptus wood
Zuidland Peter, 15-05-2023 08:25
Hello all,
I am having trouble getting to an ID with this species, it is on old eucalyptus wood, sometimes in large numbers and heaped up. Can I please get some assistance.
Apothecia are flat with only a small stipe and folds on the underneath surface.
Asci: 165-185 x 10-14um, with crosier's and Lugol's +ve for the pore walls
Spores: in water: hyaline, multiguttulate with a globose central nucleus, no septate spores seen.
Sizes: 27.8 - 39.9 x 5.7 - 6.9um
Paraphyces: extending just past asci, filiform with only a few guttules 
I hope someone can guide me.
many thanks

Re : Hymenoscyphus on eucalyptus wood
The paraphyses are surely alive though in IKI, but the asci are dead and therefore shorter.

I remember such species, but where could I have it?

The globose excipular cells exclude anything I have in Dicephalospora.

In my Phaeohelotium folders I find nothing that could fit.

Did you look in Spooner?

Re : Hymenoscyphus on eucalyptus wood
Hi Otto,
Sorry for the delay in getting back to you but my mother passed away at that time and it meant travel for vigil and funeral.
I do look in Spooner but it has many large gaps and nothing like this and I have scanned the internet in hope.
I am back to the fungi and I have found it again in another valley some distance away on old eucalyptus wood, the spores are the same and nearly 36um long with a single guttule. 
I can now make deposits of samples to the Melbourne (MEL) herbarium, permission was never needed for the state forests I visit, I can deposit this species there or send you some, whatever is easiest; direct to you would be quickest but through MEL if you want a paper out of it or new species.
Best regards

Re : Hymenoscyphus on eucalyptus wood
Dear Pete

am am very sorry about your mother. The time will come for each of us.

I placed your pics in my dearnessii s.l. folder (Asia) in Hymenoscyphus s.str., although the globose excipular texture seems to exclude this relationship.

I have a thousand papers to finish, I cannot take up a new one. Impossible also for me to do vital taxonomy on such drought-intolerant fungi from abroad.

I wish you the very best
