Hymenoscyphus on Rumex

Enrique Rubio

Hi again


Could you help me with this yellow, long stipitate, Hymenoscyphus growing in a peat bog, on Rumex sp. old stems at 1700 m of altitude? Spores allipsoid with very low oily content. Asci up to 140 x 11, IKI b of the Hymenoscyphus-type, 8-spored, arising from croziers. Paraphyses with yellow, multiguttulate VBs. Excipulum with no globulosa or angularis tissue.


I don't find any species that fits well with this collection


Thanks again

Re : Hymenoscyphus on Rumex
I was thinking about H. rumicis on seeds, but there the spores are narrower and the asci H-.

Did you look at the two left fruitbodies, are they senescent or do they contain conidia? (to be sure that it is no Symphyosirinia).

Re : Hymenoscyphus on Rumex
They are senescent. No conidia I have seen. The ascomata, very scanty, are attached to Rumex stem.
