Hypholoma capnoides[1] is a mushroom in the family Strophariaceae.

Found in both the Old and New World, it grows on decaying wood and is edible, though may resemble some poisonous species.

The cap is up to 8 centimetres (3 inches) in diameter with yellow-to-orange-brownish or matt yellow colour, sometimes viscid.

It could also perhaps be confused with the deadly Galerina marginata or the good edible Kuehneromyces mutabilis.

[4] Like its poisonous relative H. fasciculare ('sulphur tuft'), H. capnoides grows in clusters on decaying wood,[2] for example in tufts on old tree stumps, in North America, Europe, and Asia.
