Mycology
This saprophagic small gill fungus grows in large clumps on stumps, dead roots or rotting trunks of broad leaved trees. It is bitter and poisonous. The cap is hemispherical, can reach 6 cm diameter. It is smooth and sulphur yellow with an orange-brown centre and whitish margin. The crowded gills are initially yellow but darken to a distinctive green colour as the blackish spores develop on the yellow flesh. It has a purple brown spore print. The stipe is up to 10 cm tall and 1 cm wide, light yellow, orange-brown below, often with an indistinct ring zone coloured dark by the spores. The taste is very bitter.
