Sienabrauner Kelchstäubling

Arcyria incarnata is a brightly coloured myxomycete (slime mould) producing dense clusters of pink to flesh-coloured, cylindrical sporangia on decaying wood and plant litter in forest habitats. During its vegetative phase it exists as a motile plasmodium feeding on bacteria, fungi, and organic particles. This species is found worldwide in moist, shaded woodland environments with abundant dead wood.
