Aleurodiscus amorphus

This small basidiomycete forming small, confluent disc-like fruitbodies is a saprotrophic fungus fruiting on dead or terminal twigs of silver fir (Abies alba).

Easily recognizable by its discoid habit, attractive salmon-orange colour, and specific habitat.

Although most commonly found during autumn, it can appear at any season under favorable damp conditions.

Material studied was collected in late July on dead twigs of Abies alba in Santa Grazi (Zuberoa, Northern Basque Country); an additional photograph depicts another collection from Villanúa (Huesca), likewise on silver fir twigs.
