black trumpets are never guaranteed in Jura. Start with the ecological profile of Craterellus cornucopioides. Limestone plateaus, Ajoie and Franches-Montagnes defines the local frame; assess its effect on moisture, temperature and aspect.
Habitat match
Broadleaf woodland, often with beech or oak, on cool soils rich in humus. In Jura, the regional context is Limestone plateaus, Ajoie and Franches-Montagnes. Read mature broadleaf trees, dark humus, damp litter and shallow depressions without disturbing the ground.
Read the local terrain
Beech, fir and wooded pastures dominate a cool limestone landscape. This mosaic calls for comparing terrain bands rather than treating the whole canton as uniform.
Choose the timing
Late summer into autumn, with strong local variation. In Jura, elevation, aspect and moisture retention can advance or delay that indicative window.
Search plan
Choose two broad areas within this terrain: Limestone plateaus, Ajoie and Franches-Montagnes. Compare the same soil and vegetation clues, and move on when the terrain does not fit. Cepello gives no exact spot and identifies no specimen.
The map helps you search. Never identify.
Cepello helps choose an area. The app does not identify mushrooms and never confirms edibility.
