Remarks (internal):The species is known only from the type. 'M.' aureus and M. baileyi have spores which are very similar. The context hyphae of 'M.' aureus are only 2-5 µm in diam. Neither 'M.' aureus nor M.baileyi has macroscopically observable rhizomorphs; in addition the distinct, tomentose margin of 'M.' aureus, and the thick context and dimidiate habit of M. baileyi readily separates them.

Description:'Merulius' elliottii Massee, J. Bot. (Lond.), 30: 162. 1892.
Basidiocarp effused, loosely attached, of numerous small, confluent patches, overall 4 x 2 cm and averaging 0.5 mm thick; margin pallid, slightly raised, "tomentose" (Massee) or cottony, up to 0.5 mm wide; rhizomorphs abundant, white, permeating the substrate, up to 0.5 mm in diam; hymenium pale orange-yellow, brittle, shiny, "gyrose-plicate," the folds in-distinct, scattered, narrow, nearly 0.5 mm deep, pits not formed; context pallid, thin, homogeneous.
Hyphal system monomitic; context hyphae loosely woven, often coated with small, refractive droplets, frequently branched, simple-septate with occasional clamp connections, thin- to rather thin-walled, (2-)4.5-8(-10) µm in diam; subhymenial hyphae thin-walled, up to 3.5 µm in diam; cystidia lacking; basidia clavate, about 15 x 6.5 µmm; spore wall hyaline or very pale yellow, IKI-, spores some biguttulate, short-oblong, in profile adaxially flattened or slightly concave, 3.5-4.5 x (1.5-)2 µm (Fig. 2E).
Habitat: On wood, associated rot unknown.
