Hi again
On the hymenium of some decayed Ganoderma grew the basidiomata of an sterilized aphyllophoral that I tentatively determined as Trechispora vaga. But on this fungus also grew the white perithecia, on a copious white subiculum, of an Hypomyces KOH-yellow-orange. The ascospores are 1-septate, verruculose, with small apiculi. I tried to determine it with Rogerson & Samuels but no success I had. No anamorphic stage I have seen.
Could yo some idea for me?
Thanks again
did you consider Sporophagomyces chrysostomus?
Amitiés,
Christian
Hi Christian
I did not considere this possibility but, by the way,will someone have this paper?
Põldmaa, K.; Larsson, E.; Köljalg, U. 1999. Phylogenetic relationships in Hypomyces and allied genera, with emphasis on species growing on wood-decaying homobasidiomycetes. Canadian Journal of Botany. 77(12):1756-1768
Many thanks for your suggestion
Hi Christian
After reading this paper (sent me by Martin) I think you are right. I mistook the peculiar subiculum of this fungus with the basidiomata of a Trechispora. But, in spite of this, it is very curious the positive KOH reaction of the fresh perithecia of my collection, negative according Rogerson & Samuels (Hypomyces c.) and Pöldmaa & al.. Maybe an intraspecific variability?
Thank you both: Christian and Martin
