    cap The umbonate cap is 76 - 102 mm wide, red or reddish to yellowish orange over disc, becoming yellow over the marginal striations, plano-convex to plane or slightly depressed around the umbo, undecorated, and viscid when moist.  The cap's flesh is white and unchanging when bruised or cut.  The cap's margin is striate (for 35 to 50% of the cap's radius).  Volval remnants are absent or appear as a single, cottony, white, membranous patch.
    gills The gills are free to barely attached to the stem, with very faint to distinct (12 mm long) decurrent line on the very top of the stem, crowded, cream to yellow in mass, white to whitish to pale yellow in side view, and unchanging when damaged.  The short gills are distributed in [at least] two ranks.
    stem The stem is 140 - 152 × 8 - 11 mm, pale yellow above the stem's ring, yellow to white below it, unchanging when cut or bruised, narrowing upward, with dark yellow appressed scales present at least below the ring.  The stipe's flesh is white, unchanging when cut or bruised, and stuffednbsp; The ring is placed rather high on the stem (25± mm below the very top of the stem) and is membranous.  The sack-like volva is off-white, membranous, firm, cottony on the outer surface, 44 × 22 mm, and [in the few specimens seen] appears to lack a small internal limb attached to the inner side of the volva's main limb.
    odor/taste Odor and taste have not been recorded for this species.
    spores The spores measure (8.4-) 8.7 - 11.9 (-13.6) × 5.2 - 7.0 µm and are ellipsoid to elongate and inamyloid.  Basidia should have clamps at their bases, but this is not yet confirmed.
    discussion This species in known only from two collections made on the same date in the same area of Ocala, Florida.  The dominant trees at the sandy, Atlantic Coastal Plain site were oak (Quercus) and pine (Pinus).

    The present species may have the narrowest spores for any taxon of sect. Hemibapha with read on the cap from anywhere in the world.
