Hypholoma fasciculare (Huds.:Fr.) P. Kumm.

The Sulphur Tuft or Sulfur Tuft (Hypholoma fasciculare) is a common woodland mushroom, often in evidence when hardly any other mushrooms are to be found. This small gill fungus grows in large clumps (Latin fascicularis = in bundles, clustered) mainly on stumps, dead roots or rotting trunks of broadleaved trees, more rarely on conifer wood.

It is inedible; consuming it can cause vomiting and diarrhoea.

Synonym: Nematoloma fasciculare or Naematoloma fasciculare - see Hypholoma. Another English name is Clustered Woodlover.
