A reference for the fungi you actually find
Each entry describes one species the way you meet it in the field — the cap and its surface, what sits underneath, the stipe and its base, the spore print colour, the substrate it fruits from, and the species most often confused with it.

A thin, leathery toothed fungus forming zoned cinnamon funnels that fuse into rosettes across mossy conifer floors. Its white spore print separates it from the similar brown-spored Hydnellum species.
Spore print · White
Ash Dieback
Cups & Discs
A minute white cup fungus that fruits in summer on the blackened leaf stalks of ash lying in the litter. Its asexual stage produces diamond-shaped bark lesions and crown dieback on living ash trees.
