Remarks (public):The pale brown to orange colour of the pileus surface, the strong scent of coumarin, and the restricted distribution should be sufficient for a field determination. A. fragrans probably has a wider distribution in central Eastern Europe.

Hyphal system trimitic; generative hyphae with clamps, 2-4 µm in diam: skeletal hyphae thick-walled, with a distinct lumen. straight to slightly sinuous. nonseptate, pale brown, 3-5 µm in diam, negative in Melzer's reagent. in the dissepiments a few skeletal hyphae are covered with crystals; binding hyphae richly branched, thick-walled. 3-3 µm in diam. rare and difficult to find in the context.
