Nectria-like on Populus
Margot en Geert Vullings, 24-02-2025 11:54
We saw this Nectria-like on a barkless dead Populus trunk.
The round fruiting body's with a diameter of 250-260 µm are reddish in color, have a somewhat rough surface and have no stroma.
No visible purple discoloration in KOH.
The spores have 1 sept and two large guttules, no fine longitudinal stripes seen.
Measured in water: (12.3) 12.5 - 13.6 (14) × (5.1) 5.2 - 5.8 (6.1) µm ; Qe = 2.4
What species could this be?
Many thanks in advance.

Re : Nectria-like on Populus
to be found in Hydropisphaera genus.

Re : Nectria-like on Populus
Thanks Alain, that's what we expected, we thought it might be Hydropisphaera peziza, but the fruiting bodies don't dent when drying, are more red, not orange and we don't see the thin longitudinal stripes on the spores, could it be that this gets lost in old age, or is it possibly another species? The spore size is correct for Hydropisphaera peziza.

Re : Nectria-like on Populus
Another species is possible, it's a difficult genus, more than we can believe.
