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.
Blushing Morel
Morels & Allies
A pale, greyish to yellow-brown morel of mulch and disturbed ground whose ridges and stalk stain pinkish, rusty or ochre-brown where handled or with age. It is one of the earliest-branching lineages in the genus.
