About Hypholoma capnoides (Fr.) P.Kumm.
The cap of Hypholoma capnoides can reach up to 8 centimetres (3 inches) in diameter, and is colored yellow to orange-brownish or matte yellow. It is sometimes sticky to the touch, and starts out convex before flattening as the fungus ages. The stipe is yellowish, with a somewhat rust-brown color in its lower section, and grows up to 12 cm (4+3⁄4 in) long. The flesh of the fungus is yellow, and it has a mild taste, unlike most other species in the Hypholoma genus which have a bitter taste. The gills are pale orangish-yellow when young, turn pale grey when mature, and darken to purple-brown as they age. The spore print of this species ranges from dark burgundy to brown.
In terms of distribution and habitat, Hypholoma capnoides grows in clusters on decaying wood, for example in tufts on old tree stumps, just like its poisonous relative Hypholoma fasciculare, commonly called sulphur tuft. It can be found in North America, Europe, and Asia.
