Tricholoma sulphureum

Tricholoma sulphureum, also known as Sulphur Knight, is an inedible mushroom found in woodlands in Europe. It has a distinctive bright yellow colour and an unusual smell.

Description
It has a convex cap with a vague umbo up to 8 cm across, sulphur yellow in colour. The gills, stipe and flesh are similarly bright yellow. the smell, caused by the chemical scatol, is enough to distinguish it from other yellow fungi. John Ramsbottom reports that it has a complex smell that has been likened variously to Jasmine, Narcissus, Hyacinth, Hemerocallis flava, Lilac, Tagetes, decayed hemp or coal gas, as well as described as nauseating or foetid.

Distribution and habitat
Tricholoma sulphureum is found in deciduous woods in autumn.
