Pauline. PennaBonjour Please can someone help me with this id
Rutstroemia

I found this undetermined ascomycete on broadleaf wood in a botanical garden with many exotic trees.
The spores measure 19-22 x 4.7-5.4 µm.
I am thinking of Rutstroemia, but either the habitat or the spores do not match.
Any ideas?
Thank you.

Re : Rutstroemia
Why do you think R. firma does not fit? Spore size, shape and content is o.k. for it. E.g. Huhtinen 1984 measured 19-23 x 4-5 for a sample on Alnus.
There is a R. alnobetulae which could alternatively fit. I remember the contents of the paraphyses stained blue in IKI, and the ectal excipulum is more gelatinous.

Re : Rutstroemia
Hi,
I have never seen it so funnel-shaped and always with minor spores.
Thank you.

Re : Rutstroemia
R. firma is variable and occurs in a shorter- and straight-spored form. Probably there is a heterogeneity, becasue of a distinct genetical difference among collections which needs more study.
I think the apo shape is not important.
