Maren KamkeHi everybody,a week ago I found this pyreno on woo
Dactylospora?

I collected this ascomycete growing on hardwood.
Size apothecia to 800um diameter
Asci are octosporicas, 45-55 x 13-17um
The spores are finely ornamented with warts.
I think it may be Dactylospora, but I have no information.
Any idea?
Thank you, greetings
Susana

Re : Dactylospora?
Hi Susana
clearly a Dactylospora but I have never seen such broad spores which exclude D. stygia.

Re : Dactylospora?
Hi Susana
your find could probably fit to D. aeruginosa which grows on lichen but also saprobic on wood. See attached paper with a key.

Re : Dactylospora?
Good idea, Martin. But then the pigment in the exciple should be blue-violet in water (greenish in KOH) fide Ihlen et al. The pigments in Dactylospora are strongly KOH-dependent, so do you have a photo in water, Susana?
Also I did not notice a warted spore surface in the description, though this might easily be overlooked.

Re : Dactylospora?
Yes Zotto,
it might be not that easy! Hafellner 1979 (Karschia) has 9 Dactylospora species on wood (including var.s) but of course not mentioning aeruginosa, that was errected by Holien&Ihlen 2004 and not taken in synonomy with a previous known species.
The closest match in Hafellner's work is D. bloxamii.
@Susana: did you observe branched paraphyses? It is not clear from your last picture.

Martin

Re : Dactylospora?
Thanks Martin and Zotto.
If as you say adjusts to the definition of the species I file as D. bloxamii

Re : Dactylospora?
Hi Susana,
I would be satisfied when seeing the ornamentation since I never saw this species myself. Did you observe the spores with the 100x under immersion?
Best regards

Re : Dactylospora?
Yes, I have observed the ornamentation x100 (immersion)
Water photo reveals spores irregular shape because of small warts. Focusing and defocusing, get to see some small surface spots. Photographing this ornamentation is a real problem for me (I use a compact on the ocular without support), submit a photo that I think that ornamentation is sensed.

Re : Dactylospora?
Hmmm...
as you can see in the attached key of Hafellner, a warty ornamentation would lead to another species (verruculosa) but with smaller spores. If you have the same slide, now dried up a little and now thinner, try to observe it again.
Martin
Update: I just realized that Hafellner accepts in his key unsculptured spores but with other features matching for bloxamii. So I suggest as well to file your find as D. bloxamii.
