This project entered its 9th year on 15 September and today I had a find worthy of the event. In the north west corner of the Square Metre itself was a fine example of the brown birch bolete (Leccinum scabrum).
The toadstool is found with birch and must have a mycorrhizal association with one, or both, of the birches in Emthree, one of which is now of substantial size.
The top of this fungus was wet with rain, justifying the name of penny bun toadstool, but the underneath and stipe were characteristic of the species.
I am sure it will attract many fungus gnats (Mycetophilidae and relatives) and maybe other species of insect I will see what I can breed out from the numerous larvae that invariably burrow their way through the flesh of these toadstools as they mature.
