[GS] Pileus 1 .5 - 3.5 cm. diam., fuscous to greyish brown, moist and striate at margin, drying fawn to greyish fawn, carnpanulate becoming broadly conical or plane with a broad umbo; flesh thin, fawn. Gills free, white becoming greyish, moderately distant, deep. Stipe 3.5-7 cm; x 2-3 mm fawn, translucent, hollow, fragile, swollen at base. Spores 10-11 x 6-7um amyloid, thin-walled; print white. Hymenophoral trama pseudo-amyloid. Cheilocystidia 30-40 x 10um pin-head and awl-shaped (Fig. 2/52, p. 37). HABITAT: on timber of bridge, Otari, 11.5.1949, Stevenson (type). [EH] From the poor type material we recovered a few spores which correspond fairly well with the data and observations given by Stevenson. As the structure of the cuticle could not be studied the taxonomic position of this species must remain doubtful. [JAC] Material looks like its has been dried badly - cooked. Stipe with small diverticulae. Epicutis of thick walled glassy partially gelatinised hyphae without diverticulae. 2 and 4 -spored. length=8.9–11.4µm (µ=9.6, σ=0.84), width=5.6–6.8µm (µ=6.1, σ=0.48), Q=1.3–1.9µm (µ=1.59, σ=0.19), n=7. There is some evidence to suggest a few lecythiform cheilocystidia, but hard to say when the material is so badly degraded. Possibly conspecific with M. 'Ahurriri' or 'Barracouta' or even 'Rangitaiki' but insufficient evidence to distinguish. This name remains a nomen dubium.
