For the moment, please see the technical tab for information being developed concerning this species.
Mr. Krstić writes that both the odor and taste of this mushroom were farinaceous.
Based on a small number of spores, the spore measurements for this species are 4.5 - 5.0 (-5.8) × 3.3 - 4.5 (-5.2) μm. The spores are subglobose to broadly ellipsoid to ellipsoid and inamyloid. Clamps are plentiful in all known species of Limacella.

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 derived from original research of R. E. Tulloss.
[based on photograph] 49 - 56 mm wide, unevenly broadly campanulate, ??; context ??; margin incurved, nonstriate, nonappendiculate (however, see the following); gluten layer ??.
[based on exsiccata and Mr. Krstić's suggstions] nearly free, close, ?? in mass, ?? in side view, ?? mm broad, with scattered interconnecting veins between some pairs; lamellulae attenuate, of diverse lengths, plentiful and evenly distributed (between every pair of lamellae in sample).
[based on photograph and exsiccata] 67± × 8 - 9.5 mm, with white ground, subcylindric to slightly narrowing upward; bulb ??; context white, ??; annular zone superior, comprising yellow-ochraceous gluten and collapsed hyphal cortina formerly connecting pileus to stipe; gluten layer as colorless fibrils bearing yellow-ochraceous gluten, with such fibrils and coloring less evident upon drying in situ.
Odor and taste distinctly farinaceous.
bilateral, divergent; ??; vascular hyphae not observed.
pseudoparenchymatous (cellular), ??.
e.g. 23 × 5.5 μm, 4-sterigmate, ??; clamps common.
On pileus: ??. On stipe: gluten-supporting hyphae 1.9 - 4.8 μm wide, ungelatinized to partially gelatinized in dried remains of gluten, in tangled masses, at times (ungelatinized) in fascicles or singly, occasionally branching (requiring careful search to find branching points); tip cells rounded and not expanded at terminus (few located).
longitudinally acrophysalidic; filamentous undifferentiated hyphae 9.5 - 17.4 μm wide, dominating, ??, often with relatively short and slightly inflated intercalary segments; acrophysalides difficult to locate, up to ?? × 24 μm, thin-walled; vascular hyphae not observed; clamps common.
This page currently represents the results of an initial review of tissues to confirm the placement of this species in the Amanitaceae and in the genus Limacella.
Measuring spores from the lamellae was extremely difficult because the spores remained clustered on the sterigmata for the most part and were very rarely in a position to be properly measured. This was true in both basidiomes. It would appear that specimens of Limacella collected sufficiently early to reveal the original character of the universal veil analog—gluten and gluten-supporting hyphae—must have at least one specimen dedicated to producing a spore print after the material has been documented in its original condition with photographs and detailed notes.
A fragment of nrITS2 (characters 70-230) was obtained from
Siegel 1074. This fragment was an exact match to the
corresponding portion of nrITS2 in Krstić s.n.
This species was formerly called "Limacella
sp-Krstic-20-xi-2010" in these pages.

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.
