Basionym: Agaricus erysibodes Mont. [as "A. (Hebeloma) erysibodes"] (1856)
Types: UNITED STATES: Ohio: Columbus (approx. 39.9612°N, 82.9988°W, alt. approx. 230 m a.s.l.), 1846, J. Robinson (206), det: W.S. Sullivant (Holotype. herbarium acc. no. no reference number, HJB1000544; Isotype. herbarium acc. no. WTU-F-039665, HJB1000351).
Original diagnosis: Pileo carnoso convexo obtuse vel obsolete umbonato expanso, disco squamoso, margine inflexo striatulo; stipite basi incrassato solido apice spongioso-farcto, sicco striato glabro; lamellis tridymis confertis latissimis triquetris seu postice truncatis uncinato-adnexis subdecurrentibus tabacinis; sporis ovoideis ferrugineis.
English translation: Pileus fleshy convex obtuse or indistinctly umbonate expanded, squamose on the disc, margin inflexed slightly striate; stipe enlarged at base solid spongy-stuffed at the apex dry striate glabrous; lamellae tridynamous (threesome) crowded very broad triquetrous (three-sided, triangular) or at the attachment truncate uncinate-adnexed (emarginate) subdecurrent tobacco brown; spores ovoid rust-coloured.
Commentary: Murrill (1924) concluded: “When examining the type of this species at Paris some years ago, I made a record that the specimens were well preserved and very much resembled one of our common wood-loving species of Gymnopilus.” Our morphological study plus our study of the protologue and icon confirms this to be a species of Gymnopilus. The latin diagnosis utilises the term Tridynamous (threesome) meaning In groups of three. This should probably be interpreted as that between two entire lamellae there are three lamellulae the one in the middle longer than the two on the sides.
