On salix bark
Margot en Geert Vullings, 05-02-2025 11:50
On the inside of Salix bark we found white rosettes, which turned out to be an anamorph.
This is the second time we find this on Salix.
Conidia measured in water: (4.9) 4.93 - 5.7 (5.9) × (1.1) 1.3 - 1.5 µm ; Qe = 3.8
Does anyone have an idea which anamorph this could be?
Many thanks in advance, Margot&Geert

Re : On salix bark
I have possibly the same in my Dendrodochium folders in Hyphomycetes: on Salix, 31.XII.2006. The apothecioid shape misleads to expect asci, e.g. of a Parorbiliopsis (Hyaloscypha). I measured coniia *4.2-6.3 x 1.3-1.5 µm, conidiophores very long & thin. I fear these fungi are badly explored, which is a surprize since hyphomycetes are intensely studied.

Re : On salix bark
Thanks for the answer, pity it does not become clear.
Indeed, we also thought of an ascomycete.

The first find was not on Salix, but on Alnus we saw later.

Kind regards, Margot&Geert
