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.
Gypsy Mushroom
Gilled
A sturdy ochre mushroom with a radially wrinkled cap dusted silvery-white over the centre, rusty-brown gills, and the unusual distinction of a true membranous ring on a webcap.
Spore print · Rusty ochre-brown
