Cheirospora botryospora
Eduard Osieck, 26-11-2017 15:01
Would anyone be able to confirm that this anamorph (coelomycete) is Cheirospora botryospora? It forms characteristic black effused patches on dead branches of Carpinus betulinus (and Fagus and Hedera according to the literature).

The species is described and illustrated by Sutton 1980 (page 203) and Ellis & Ellis 1997 (fig. 634).


Thanks in advance, Eduard

Re : Cheirospora botryospora
Did you also compare Periconia? The anamorph of Patellariopsis atrovinosa reminds me of this.

Re : Cheirospora botryospora
Thanks for your comment. I did not consider Periconia in detail because the species concerned, to my knowledge, form separate condiophores as shown in your photos "Periconia minutissima, HB 8187b". Or are such coniophores not typical for the genus as a whole?

Re : Cheirospora botryospora
Yes, this looks really different. But the anamorph of Patellariopsis forms such cushions and we always referred it to Periconia. Your fungus matches well those I have in my Cheirospora folder indeed. 

I see only one photo Patellariopsis atrovinosa, 8.IIII.2016-4.jpg in my folder showing this anamorph. Surely Guy Marson would have more pics of it.

Re : Cheirospora botryospora
Thanks, I found the mentioned picture in your Durella folder. On photos 2 and 3 of the same series a label is shown with the text "Cheirospora". From the description file I understand that ?Patellariopsis atrovinosa was collected close to Cheirospora from a Carpinus branch still attached to the tree (as in my collection). Do you consider it likely that Cheirospora botryospora is the anamorph stage of Patellariopsis atrovinosa?

Are you aware of a recent publication by Crous et al. in which Cheirospora botryospora is included? A quote from the discussion: "Cheirospora botryospora (Helotiales, Leotiomycetes) is common on branches of Fagus sylvatica in Europe (Sutton 1980). Although its phylogenetic position has remained unclear until now, we were surprised to find that it formed a Phialophora synasexual morph in culture. The LSU sequences of the strains place it in Helotiales, with Acephala applanata (GenBank KF951051) as closest sister (Fig. 1)."

Re : Cheirospora botryospora
I had downloaded these Cheirospora and Acephala sequences and analysed them. they actually cluster in a supported clade with a Mollisia (M. "albogrisea").


The only uploaded sequence of several of P. atrovinosa (KY462814) is quite different. Guy sequenced also the Periconia which he seems to call P. cambrensis, and it fits perfectly the teleomorph.

Re : Cheirospora botryospora
Thank you very much for the additional information. It would be nice if the teleomorph is found in the near future. Cheirospora botryospora is common on dead branches stiil attached to the tree in my study area.

Cheers, Eduard
