Calycina (?) on Epilobium angustifolium

Hi to everybody


These very small (up to 0.5 mm), superficial, gregarious, very shortly  stipitate whitish apothecia with a convex hymenium grew on Epilobium angustifolium old stems at 1500 m.


The margins are only  downy by smooth very packed cells with no Vb's. Excipulum of an elongate textura prismatica of hyaline cells with slightly gelified walls. Asci up to 70 x 9, 8-spored, IKI red-blue, arising from croziers. I cannot study well the paraphyses but I tink they are not conspicuous VBs. Ascospores with high oily content.


Have you some idea?


Thanks again

Re : Calycina (?) on Epilobium angustifolium
One of the paraphyses is alive and contains a VB, though not very refractive. But your pdf has a low resolution, could you please send me the plate in high resolution? I need to see the hairs more closely.
