Physarum robustum

Mature sporocarps

Physarum robustum is a common species in the UK. It is usually found on dead wood. It is one of the few myxomycetes that produces stalked and sessile sporocarps and plasmodiocarps in the same development. Physarum leucophaeum is similar in appearance but only forms stalked sporocarps. As usual, to be sure of identification microscope work is needed.
