This mushroom is represented by a single, annotated collection and some additional, unvouchered photographs from the original collecting site in New Zealand. Given the sparsity and poor quality of the literature on Limacella, it is undetermined at present.
The cap is 45 - 60 mm wide, convex to plano-convex, pale yellowish brick-brown, darker towards the disk, viscid to glutinous when wet, and having fine, short hairs when dry. The surface sometimes splits revealing the white cap flesh. The cap's margin is not striate and extends beyond the ends of the gills. Fine, loosely interwoven, fibrillose material can be found on the margin in young specimens.
The gills are free, close, white to pale cream or buff, and narrow toward both ends in mature specimens. The short gills are ??.
The white to pale buff stem is 50 - 70 × 7 - 15 mm, narrows upward, and is approximately club-shaped. The stem's flesh is solid and cartilaginous. In young specimens only, the stem has a ring that is located at about mid-stem; this ring suggests a spider's web, disappears with time, and leaves remnants on and near the cap's margin and (sometimes) just above the stem's base [often attached to a ring of gluten (sometimes slightly more yellow than the gluten on the cap) from the cap's edge]. The remnants of the ring and cap gluten on the lower stem are seen most frequently in young specimens.
Odor and taste are not yet recorded.
The spores measure 5.0 - 6.0 × 5.0 - 5.6 (-6.0) µm and are globose to subglobose and inamyloid??. Clamps are present?? at the bases of basidia.

Due to delays in data processing at GenBank, some accession numbers may lead to unreleased (pending) pages.
These pages will eventually be made live, so try again later.
Olive text indicates a specimen that has not been
thoroughly examined (for example, for microscopic details) and marks other places in the text

45 - 60 mm wide, convex to plano-convex, pale yellowish brick-brown, darker towards disk, paler towards margin, viscid to glutinous when wet, finely pubescent on drying, with gluten and mass of gluten-supporting hyphae splitting in aged specimens and then exposing context; context white, ??; margin non-sulcate, exceeding lamellae, appendiculate with fine, loosely interwoven, fibrillose material in young specimens.
free, close, white to pale cream or buff, subventricose in mature specimens, ?? mm broad, with margin entire (wavy [or eroded??] in mature specimens); lamellulae ??.
50 - 70 × 7 - 15 mm, narrowing upward, subclavate, white to pale buff, concolourous with lamellae; bulb lacking??; context solid, cartilaginous; partial veil median, arachnoid, fugacious and only visible in young specimens, leaving remnants on pileus margin and just above stipe base in young specimens, with latter remnants bearing ring of gluten concolourous with gluten on pileus, but slightly more yellow.
[Note: The glutinous ring on the young stipe is probably a part of the gluten layer that developed attached to the partial veil and/or the incurved edge of the cap. One of the hypotheses of Reijnders was that the arachnoid partial veil in section Limacella at least partially is an extension of the hyphae of the gluten layer that grows toward and connects with the stipe (this seals off the cavity into which the gills grow (downward from the underside of the pileus context). One of the things that needs to be done is to clarify how we talk about the partial veil and the gluten layer. Do we treat them as complete and separate entities in the "adult" mushroom? Do we treat them as a stage in a complex development process?—RET]

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.
