Gorgoniceps species?
Lieve Deceuninck, 14-11-2016 12:16
Lieve DeceuninckDear Forum members
I received this find from a friend. Could this be a species of Gorgoniceps?

On soaked hardwood (decidious forest)
Apothecia 05-0.5x0.3-0.5 mm, light greyish green; without hairs, the' hairs' on the macro picture may be some emerging asci.
Spores: 40-45x4-4.5 µm with 7, quite thick, septa, hyaline with refractive content
Asci 110-120(140)x 11-13(17) µm,with croziers, IKI+, top and wall blueing
Paraphyses: 100-120x2-2.5 µm; filiform, with refractive content
Textura porrecta, textura poorly developed


Thanks in advance for any reaction.


Regards, Lieve

Hi Lieve,

I think it could be a Strossmayeria.

Best wishes,
Gernot

Fits very well, with anamorph, many thanks!

Re : Gorgoniceps species?
yes, for sure, and usually we identify S. basitricha. That names comes from the always associated asexual state with dark brown conidiophores and brown thickwalled septate conidia.

Re : Gorgoniceps species?
Just noticed that you report the asci as IKI+. Are you sure about that? If memory serves me right, S. basitricha shows no such reaction although the excipulum often reacts clearly blue in Lugol.

Best wishes,
Gernot

Re : Gorgoniceps species?

Dear Gernot


I looked at it again and read the introduction of Iturriagas & Korfs 'Monograph of the discomycete genus Strossmayeria, with comments on its anamorph'.  Because of the amyloid spores I was wrong. Asci IKI-, spores IKI+.


Thanks for your advice and also thanks at Hans-Otto!

Re : Gorgoniceps species?
Hi Lieve
on your photo the asci are inamyloid. I know about the amyloidity of spores, but I am not sure if I ever saw it. On the other hand, the blue excipular  reaction is wquite distinct.
Maybe the spore amyloidity is only visible in overmature spores, as in Durella connivens which is phylogenetically closely related.

Re : Gorgoniceps species?
Thanks for you critical eye. I found more mature ascomata but the 'reaction' is the same. Probably I've had to notice that it is just a strong refraction of the light?

Re : Gorgoniceps species?
I cannot see a reaction on your pics.

Here in attach an arrangement of pics by Ingo Wagner which shows the reaction in Durella connivens quite well.
