     Several of the key identifying characteristics listed above are expressly designed to rule out the poisonous Sulphur Tuft (N.fasaculare; see p. 159). It occasionally has been mistaken for the Smoky-gilled Naematoloma, but the toxic species has a greenish yellow to bright orangish yellow cap and, usually, bitter-tasting flesh. The gills of young Sulphur Tufts are greenish yellow to sulphur yellow, darkening to purplish brown in age.

     The similar but less common Sulphur Tuft, Hypholoma fasciculare, is a yellow mushroom yielding a purple-brown spore print; it grows on logs and stumps. The Sulphur Tuft is very bitter. Poisonous, it causes nausea, vomiting, and abdominal pain.
