intro |
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. | ||||||||||||
pileus | [based on photograph] 49 - 56 mm wide, unevenly broadly campanulate, ??; context ??; margin incurved, nonstriate, nonappendiculate (however, see the following); gluten layer ??. | ||||||||||||
lamellae | [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). | ||||||||||||
stipe | [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/taste | Odor and taste distinctly farinaceous. | ||||||||||||
macrochemical tests |
none recorded. | ||||||||||||
pileipellis | absent. | ||||||||||||
lamella trama | bilateral, divergent; ??; vascular hyphae not observed. | ||||||||||||
subhymenium | pseudoparenchymatous (cellular), ??. | ||||||||||||
basidia | e.g. 23 × 5.5 μm, 4-sterigmate, ??; clamps common. | ||||||||||||
gluten layer | 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). | ||||||||||||
stipe context | 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. | ||||||||||||
partial veil | absent. | ||||||||||||
lamella edge tissue | fertile. | ||||||||||||
basidiospores | [10/1/1] 4.5 - 5.0 (-5.8) × 3.3 - 4.5 (-5.2) μm, (L = 4.7 μm; W = 4.1 μm; Q = 1.09 - 1.32 (-1.36); Q = 1.17), hyaline, colorless, smooth, thin-walled, inamyloid, subglobose to broadly ellipsoid to ellipsoid; apiculus sublateral, cylindric; contents granular to multiguttulate to "oil drop" type; white in (scant) deposit. | ||||||||||||

discussion |
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 Zhuliangomyces. 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 s.l. collected sufficiently early to reveal the original character of the—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.
