Hymenoscyphus repandus ?
1 October 2023
I found this beautiful, yellow cup fungus at the allotment.
The cups are millimetres in diameter and are on rotting softwood.
A Google image search suggests a Hymenoscyphus species and at a recent Norfolk Fungus Study Group foray, this was also suggested.
After some further recent research, maybe it’s Hymenoscyphus repandus ?
A week later…
