Found at the base of dead stems of Anethum graveolens (Apiaceae).Spores 15-17,4x2,2-2,9um Q=5,5-7,1 ends rounded, some guttules inside.
Ascus IKI+, pleurorhynques, spores biserriate
Paraphyses l=2,1-2,9um with a slightly enlarged apex (l=4um).
Any idea ?

Re : Phaeohelotium sp.
Hi Yannick
this is a Calycina, possibly C. subherbarum (I do not see the ascus base well). Compare also C. heterospora, which turns red with age, however.

Re : Phaeohelotium sp.
Thank's Zotto.
Well... I don't know. I don't know C. subherbarum.
I don't think it's C. heterospora because apos don't turn red when hurted. And apical rings of ascus are blue in IKI.
Here is a photo of ascus base.
Thank's for your help.

Re : Phaeohelotium sp.
Yes, clearly with croziers. So I think it is C. subherbarum. Apos are perhaps over 1 mm?

Re : Phaeohelotium sp.
Thank's again. Apos are 1-2mm wide.
Have you got a reference of a publication for C. subherbarum or is-it a work name ?

Re : Phaeohelotium sp.
It is a working name. There is a valid Hymenoscyphus subherbarum which seems a Calycina too but has much smaller spores.
