Octospora lilacina?
Georges Greiff, 25-11-2021 13:47
Hello,

I have been sent an interesting Octospora from acidic soil in south west England, growing beside a large patch of the leafy liverwort Solenostoma gracillima and moss protonema (Dicranaceae sp.).

Apothecia orange, margins poorly developed, up to ±1.5mm diam. Asci 8-spored with flat apices. Paraphyses with wide, swollen tips lacking VBs. Ascospores 17.5 - 19.5 x 10.5 - 12.0, with inconspicuously reticulate surface (I think - I have no LCB at the moment to stain).

The best match seems to be O. lilacina, but the apothecia are orange rather than lilac. Other than that, it fits pretty well. Any comments welcome.

Best wishes,
George

Re : Octospora lilacina?
My first idea was O. humosa but the apo size and associated mosses contradict this. O. lilacina has hyaline VBs instead of carotenoids.

Re : Octospora lilacina?
Thanks, Zotto. Perhaps the host protonema is Pogonatum aloides, where leafy shoots are absent.  I agree that it is an odd one.
