Fungi encyclopedia
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 Bracket
Polypores
A flat, radially wrinkled bracket in reddish and tan bands whose pale maze-like underside flushes distinctly pink-red wherever it is touched.
Spore print · White
Blushing Milkcap
Gilled
A very large, heavy white milkcap blotched with wine-red or vinaceous patches, distinguished by crowded pink gills and copious white latex. It grows exclusively with poplars and willows, often in dune slacks and damp sandy ground.

Blushing Rosette
Polypores
An oddly shaped cream to pinkish-buff polypore forming rosettes or lopsided funnels on the ground above buried roots, staining reddish brown where handled and often weeping red droplets.
Spore print · White
Bolete Eater
Other Fungi
A parasitic fungus that engulfs boletes in a felty white coat which ripens to bright golden yellow, distorting the host until its pores and stipe are barely recognisable.
Spore print · Not applicable; golden-yellow powdery spore mass
