Sulphur tuft toadstools (Hypholoma fasiculare) are common in all types of woods and forests. The name translates as “mushroom that grows in bundles” – they often form tight clumps.
These fungi feed on rotting wood (saprotrophic). Those pictured were found on a conifer stump alongside the track. In their prime, the sulphur-yellow caps have vivid orange centres. The gills are yellow.
Many of the mushrooms found in these woods are inedible; this one is particularly poisonous – consuming it can cause vomiting, diarrhoea and convulsions.
