Mollisioid on wet wood

Hi All,


I have found a mollisioid fungus on very hard, partly submerged wood, probably Alnus. The yellowish apothecia are about 1mm, some completely submerged in fresh water.


Ascospores: Ellipsoid, 8-11.5x4.3-6.


Asci: 78-120x6-9. Pore weakly blue in Melzer's.


Excipulum agglutinated with orange-brown matter at the margin.


Paraphyses with Vbs. Enlarged to 4-5.


Best wishes,


Charles.

Re : Mollisioid on wet wood
This is hymenoscyphoid rather than mollisioid. I suggest Phaeohelotium imberbe /Hym. imberbis.

Hi Zotto,


Many thanks for this. I had thought the spores a bit wide (lower Q) for H. imberbis but I think that could be down to natural variability. Certainly, the apothecia  seem to show quite a range of colour.


Best wishes,


Charles.

Re : Mollisioid on wet wood
Hello Charles,

Do your macro photos have a yellow colour cast? 

I agree that this is Hymenoscyphus imberbis, as Zotto says, but I have never seen the fruit bodies looking as yellow as this.

With Best Wishes,
Peter.

Re : Mollisioid on wet wood
I should add that the asci must arise from croziers, which is possible here but not clearly seen. H. imberbis turns reddish with age, and indeed a yellow colour I am also not used to see.

Hi Zotto and Peter,


Yes, the apothecia are definitely yellowish. I could not find croziers after a purposeful search.
