| 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 not directly from the protolog of the present taxon and not cited as the work of another researcher is based upon original research by R. E. Tulloss. The following is based on the protolog, the revision of the holotype by Tulloss, and the description by Smith (1966). | ||||||||||||||||||||
| pileus |
??, glutinous, but drying rather quickly; context very thin, ??; margin ??; gluten layer present. [Note; H. V. Smith says the gluten layer is very clear when the pileus surface is mounted in Melzer’s reagent—despite Murrill’s saying the pileus is "dry" in the protolog.] | ||||||||||||||||||||
| lamellae | narrowly adnate, ??; lamellulae ??, of diverse lengths, ??. | ||||||||||||||||||||
| odor/taste | not recorded. | ||||||||||||||||||||
| macrochemical tests |
none recorded. | ||||||||||||||||||||
| pileipellis | absent?? | ||||||||||||||||||||
| basidia | 18–26 × 5–6.5 µm, 4-sterigmate, ??; clamps lacking??. | ||||||||||||||||||||
| gluten layer | On pileus: gluten-supporting filamentous undifferentiated ?? µm, slightly refractive, thin-walled, ??; terminal cells of such hyphae ?? µm, with basal septum ?? µm wide, with length/max.-width ratio = ??, narrowing upward, subtended by inflated cells 20–36 × 7.8–13 µm or uninflated hyphal segments (2.5–) 3.5–5.2 µm wide and up to 48 µm long; clamp connections ??lacking??. | ||||||||||||||||||||
| basidiospores |
"5–5.5 µm diam." (est. Q = 1.18), thin-walled, faintly stippled, inamyloid, subglobose to broadly ellipsoid, adaxially somewhat flattened; apiculus sublateral, “prominent,” cylindric; contents not described; color in deposit unknown. [Note: While the spore measurements and accompanying text suggest that the spores are globose, the spore drawings reveal that they are not; Q is provided for the one spore that is drawn in lateral view.] | ||||||||||||||||||||

| discussion |
This species may not be a Limacella. Smith (1966) proposed recombination of Murrill’s epithet in Limacella on the grounds of the spore shape and size, the “nature of the cuticle” (i.e., of the gluten layer on the pileus), and the bilateral trama of the lamellae. The type should be examined to check the stipe context and to re-examine the spores, etc. If this is a Limacella, it is very odd that Smith shows no clamps in her drawiings and states that she found none in the "cuticle" (i.e., the gluten supporting hyphae of the gluten layer on the pileus). Also, her assertion of the presence of cheilocystidia must be checked. The shapes of the terminal cells of the volva described and drawn by Smith (1966: pl. I, figs. 11, 15, 16) strongly suggest that this species, if a Limacella, should be placed in subsect. Amanitellae. Compare L. guttata sensu H.V. Smith of North America. | ||||||||||||||||||||

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.
