Read cool beech woodland for black trumpets
Black trumpets are mainly associated with broadleaf woodland, often with beech or oak. Dark litter, intact humus and shallow hollows can retain useful coolness after rain.
Their colour hides them among leaves. Walk slowly without raking or turning litter. After finding one group, observe the same contour and continuity of microhabitat rather than trampling widely.
Check shape and outer surface
A small dark funnel fungus is not automatically a black trumpet. The cavity, thin flesh, outer surface, transition to the stem and condition all require inspection.
Very old or soaked specimens lose features and deteriorate quickly. Discard degraded mushrooms and have every specimen intended for consumption checked separately.
Identification and lookalikes
Other dark or funnel shaped fungi may appear similar. Shape, underside, texture, stem, habitat and condition of every specimen must be checked.
The map helps you search. Never identify.
Cepello does not identify mushrooms and never confirms that a specimen is edible. Have your entire collection checked by an official inspection service.
