Scutellinia question
Chris Yeates, 14-09-2014 16:00
Chris YeatesBonjour tous
This Scutellinia was collected on sodden wood by a small stream with Alnus glutinosa  (mycologically rich, with two Naucoria spp., Laccaria tortilis and Coprinopsis laanii all close by). On spore characters I tentatively make Scutellinia crinita, but the hairs seem rather short.
Apothecia - largest 13mm across
Hairs - bi-multi-furcate at base, none seen longer than 760mm
Ascospores - (18)19.8-21.4 x 12.4-13.8(14)µm; Qe = 1.5 / 1.6
My experience of this genus is limited - any help welcome
Cordialement
Chris

Re : Scutellinia question
Adio Chris,

In my opinion, with these data, this collection is perhaps S. olivascens.
But it's difficult to compare sporal ornementation with this sort of microscopy, I haven't the habit !
Could you verify if hairs are flexuous like a long etirated S ? Like on my drawings :

In answer to your question I would say "yes". See the attached image (a temporary file, used for measuring, retrieved from my Recycle Bin!) I am sure I can provide better ones if needed.
best wishes

Re,

For me, it's good. S. olivascens seems to be a good option.
In fact, macro corresponds too !

Re : Scutellinia question
Many thanks Beñat!
I apologise for taking so long to get back on this. I now have better images of the hairs, which, I think, conform well with your drawing.
Cordialement
