The mature cap is brownish red in the center and
yellow over the outer parts of the marginal
striations. There are no universal veil
remnants on the cap.
The stem is lemon yellow at the apex and otherwise white, has yellow fibrillose-felted patches below the annulus, and bears a membranous ring that is soon brownish orange. The volva at the stem's base is sack-like, membranous, and white.
This species has a mild odor. It's taste is not recorded.
Spores of this taxon measure (8.5-) 8.7 - 11.2 (-12.1) × (5.9-) 6.0 - 7.4 (-8.2) μm, are ellipsoid to elongate, and are inamyloid. Clamps are probably common at bases of basidia.
This taxon is known only from a single collection from Queensland, Australia. The material was found in association with trees of Allocasuarina and Eucalyptus.—R. E. Tulloss

Olive text indicates a specimen that has not been
thoroughly examined (for example, for microscopic details) and marks other places in the text
where data is missing or uncertain.
The following material is based on the collectors' annotations of the fresh material and original research of R. E. Tulloss.
50 - 70 mm wide, brownish red (6C6) over disc, bright yellow (3A5) over outer parts of marginal striations, planar, moist and tacky, not viscid; context white with yellow tints, unchanging, 8 mm thick over stipe; margin sulcate-striate; universal veil absent.
adnate, crowded, color??, with fimbriate yellow edge; lamellulae truncate.
90 - 130 × 8 - 10 mm, lemon yellow at apex, otherwise white with lemon yellow floccose zones, subcylindric; context yellow, hollow; partial veil apical, membranous, flaring, soon appressed to stipe, soon brownish orange; universal veil as saccate volva, white, membranous.
Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer;
and explanations prepared for this site talk about specimen-observer pairs associated with each data set.
Combining more data into a single data set is non-optimal because it obscures observer differences
(which may be valuable for instructional purposes, for example) and may obscure instances in which
a single collection inadvertently contains a mixture of taxa.
