Sulphur tuft or ‘clustered woodlover’, is a common woodland mushroom, and often seen when hardly any other mushrooms are to be found. This saprotrophic small gill fungus grows prolifically in large clumps on stumps, dead roots or rotting trunks of broadleaved trees. It is probably one of the most common fungi living on the Barff.

Sulphur tuft is bitter and poisonous, eating it can cause vomiting, diarrhoea and convulsions. Visible from April through to December on the Barff.
