Boletus aereus is associated with warmth-loving broadleaf woodland, but the evidence supports no universal pH threshold. Texture, drainage, humus, partner trees and local climate must be combined.
What the evidence says about soil
Boletus aereus is associated with warmth-loving broadleaf woodland, but the evidence supports no universal pH threshold. Texture, drainage, humus, partner trees and local climate must be combined.
Fruiting records describe tendencies rather than a simple mechanism, and they include search bias. The factor must be combined with habitat, elevation and preceding weather.
The species ecological context
Warm, open, mature broadleaf woodland, especially with oak and sweet chestnut. Summer into early autumn in warm areas. Listed as Vulnerable in Switzerland in the 2007 Red List.
The visible mushroom is only a temporary fruiting body. Mycelium can be present without fruiting during a visit, and nearby slopes can develop differently.
Soil pH never proves presence
A local correlation does not become a national rule. Cepello ranks potential habitats but detects neither mycelium nor mushrooms in real time.
Combine soil, vegetation and terrain
Before a trip, compare several signals and do not disturb the soil. Respect property, reserves and cantonal rules, and have every collection checked before eating it.
FAQ
Frequently asked questions
Is this factor enough to find the mushroom?
No. It must be combined with habitat, season, moisture, elevation and other local conditions.
Does Cepello guarantee a find?
No. The map compares potentially favourable conditions. It reveals no precise spots, detects no mushrooms and never confirms identification.
