intro	This description is based largely on material (including collections seen in fresh condition) revised by RET.
cap	The cap is 22–30 mm wide, reddish brown (fading to rufus or fulvous with reddish brown in the center after collection), apparently not changing color when bruised, broadly convex to planar, subumbonate or with a low central umbo, and glutinous. The cap's flesh is white or off-white, with a dark line above the lamellae, very palely concolorous with the volva in a very narrow region below the volva, and 2.5 mm thick above the stem. The margin is very slightly incurved, nonstriate or faintly striate here and there, and exceeding the ends of lamellae by 1^± mm. The gluten layer (including the supporting hyphae) peels to the cap's central part.
gills	The gills are free, close to crowded, off-white to pale yellowish cream in mass (except sometimes palely concolorous with the cap's slime near the cap's margin), in side view pallid and water soaked or off-white near edge and pale yellowish to pale tannish white near pileus context, apparently not changing color when bruised, subventricose, 5^- mm broad, proportionately rather thick, and having a somewhat uneven wavy edge. The short gills are narrowing in an irregular manner toward the stem, very plentiful, of diverse lengths, and somewhat unevenly distributed.
stem	The stem is 28–67 × 2.5–6 mm, with a pallid ground color, with streaky red-brown gluten (later visible as red-brown fibrils) over approximately the middle third of the stem below the ring or over the lower half or lower two-thirds of stem, cylindric or very slightly narrowing upward, barely flaring at the top, glutinous, and has a white base that is blunt to narrowly clavate and decorated with white mycelial threads. There is no bulb. The flesh is solid, white below, off-white with fine longitudinal watery streaks above, and sometimes with a rufus tint near the stem's surface. s A "ring" is present as a fibrillose (somewhat tufted) zone on the upper stem; it is white above and reddish or pinkish brown on the part most distant from the stem surface. The gluten layer on the stem is the same color as that on the cap and covers the stem below last point of contact with cap; this coloring is most intense in a complete undulant ring adjacent to, and below, the "ring zone."
odor/taste	The odor is medicinal or mildly unpleasant or sometimes rather strong when the cap has been "peeled."
spores	The spores measure (3.6–) 3.9–4.6 (–5.3) × 3.5–4.4 (–5.0) µm and are globose to subglobose (infrequently broadly ellipsoid) and dominantly inamyloid, with some dextrinoid. Clamps are plentiful at bases of basidia.

intro

The following text may make multiple use of each data field.

The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material.

The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate.

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 collector's notes and original research of R. E. Tulloss.

pileus

from protolog: 30 - 40 mm wide, brown, darker in center, subovoid then convex and expanded; context rather thin, white, fleshy; margin ?; gluten layer brown, continuous with "marginal veil" and gluten on stipe.

22 – 52 mm wide, reddish brown, fading to rufus or fulvous with reddish brown disc after collection [no good matches in Munsell (1975)], in Kuo 07020702 brownish yellow without visible red tint (leaving yellow stain on waxed paper), in Braaten s.n. mottled orange and yellow, apparently not changing color when bruised, broadly convex to planar, often subumbonate or with low broad central umbo at least at first, glutinous; context white or whitish or off-white, unchanging when cut or bruised, sometimes with dark line above lamellae, very palely concolorous with gluten in very narrow region below gluten layer, 2.5 mm thick above stipe, thinning evenly for one half to two-thirds R, thence of constant thickness (or thinning very slowly) to margin; margin very slightly incurved, nonstriate or faintly striate here and there, exceeding ends of lamellae by 1^± mm; gluten layer orangish tan, reddish brown over disc, very pallid near and at margin, source of pileus pigmentation, with gluten-supporting hyphae, and probably hyphae from upper context together peeling to disc.

lamellae

from protolog: free, close, white, rounded behind, approximate, broad; lamellulae not described.

free to very narrowly adnate, close to crowded, off-white to pale yellowish cream in mass (except sometimes palely concolorous gluten pile on pileus near pileus margin), in side view pallid and water soaked or off-white near edge and pale yellowish to pale tannish white near pileus context, apparently not changing color when bruised, subventricose, 5^- mm broad, proportionately rather thick, with somewhat uneven wavy edge; lamellulae irregularly attenuate to attenuate, very plentiful, of diverse lengths (about half very short), somewhat unevenly distributed (sometimes 2 between pair of lamellae, sometimes 4 or 5, sometimes none).

stipe

from protolog: 40 - 60 × 3 - 4 mm, whitish and fibrillose under gluten, narrowing upward; context solid; bulb not mentioned; partial veil not mentioned; gluten layer brown, continuous with that on pileus.

28 – 84 × 2.5 – 10 mm, with pallid ground color, with streaky red-brown gluten (later visible as red-brown fibrils) over approximately middle third below partial veil to lower half or lower two-thirds of stipe, cylindric or very slightly narrowing upward, barely flaring at apex, glutinous, with white base blunt to narrowly clavate and decorated with white mycelial threads; bulb lacking; context solid, white below, off-white with fine longitudinal watery streaks above, sometimes with rufus tint near surface; partial veil as fibrillose (somewhat tufted) annular zone, superior, white above, reddish or pinkish brown on part most distant from stipe; gluten layer concolorous with that on pileus covering stipe below last point of contact with pileus, coloring most intense in complete undulant ring adjacent to, and below, annular zone.

odor/taste

Odor like cucumber or medicinal or mildly unpleasant, sometimes rather strong when pileal gluten pile "peeled." Taste not recorded.

macrochemical
tests

Spot test for laccase (syringaldazine) - In mature material, strongly positive in disc and stipe base in about 1 min; after 2 min positive throughout pileus context, on edges of lamellae, and in apical and basal thirds of stipe; beginning to fade about 8 min after application of reagent.
Spot test for tyrosinase (paracresol) - negative throughout mature basidiome, except for possible faint positive in disc.
KOH - no reaction on pileus.

discussion

ROUGH NOTES ONLY

Additional material: In WTU, there are 3 collections.

Moser’s illustration is of IB 88/177.

RET could not confirm the observation by H.V. Smith (1945) of fine punctate decoration to the spore wall in Melzer’s reagent or in 3% KOH when viewed at 1250× either with normal bright field or with Nomarski DIC.

Spore data for collections
provisionally identified as: Limacella glischra (Morgan) Murrill

Spore data sets and their composite

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.
