Dactylospora sur Buxus sempervirens
Gilles Corriol, 25-05-2013 15:18
Gilles CorriolJe tente à nouveau ma chance avec un Dactylospora.

Récolte sur branche morte de Buxus sempervirens colonisée par Peniophora proxima. GC13051713.

Spores 16,3-20,7 x 4,7-6,0 µm, brunes, à 3-7 cloisons transeversales et parfois légèrement muriformes.
Asques à paroi épaisse, sommet amyloïde et base dextrinoïde.
Paraphyses multicloisonnées, à article terminal clavé, à pigment brun épipariétal.
Textura angularis. Excipulum ectal brun foncé, globulosa.

Avec la maigre documentation sur ce genre à ma disposition, je vais vers D. frigida.

Merci d'avance pour vos avis.

Re : Dactylospora sur Buxus sempervirens
There is a similar species on Crataegus ("submuriformis") in which the hymenium and excipulum stains pinkish-lilac in KOH. So could you please look what colour your section takes in KOH?

Re : Dactylospora sur Buxus sempervirens
Here it is. Yes, very nice reaction in KOH 5 %.
So it is an unpublished species of yours ?

Thank you for your very appreciated help !

Re : Dactylospora sur Buxus sempervirens
One of Guy Marson's undescribed species.

Important is to look whether the spore wall is smooth or warted. Do you have a close-up of a spore? Also by focussing on the wall surface?

Re : Dactylospora sur Buxus sempervirens
Hi friends,
I regurlarly meet this nice little discomycete since 2008. I've very recently found it. Exactly the same.
Did you, or Guy,  get taxonomical news since 2013 ?
As the bark of my branch is greened, I thought for a while of a lichenized fungus. But nothing assures me that the alga is associated with this fungus. Presence also in the vicinity of 3 liverworts: Metzgeria furcata, Radula complanata and Frullania dilatata.
Best wishes,
Alain

Re : Dactylospora sur Buxus sempervirens
Hi Alain, I am not really familiar with this genus. There exist some sequences by Guy from submuriformis on Crataegus. In the meantime, one must take care also of the anamorph, no idea if any was described on Buxus. The generic name Sclerococcum is now used instead of Dactylospora. (see Olariaga et al. 2019)

Thanks Zotto.
I keep material in herbarium, for future...

Re : Dactylospora sur Buxus sempervirens
I am sceptical if there will be anyone to describe these. Perhaps in 100 years :-(
