intro	The following material is derived from the original description pf Limacella subillinita and original research by R. E. Tulloss and J. Geml.
cap	The cap of this mushroom is 15–55 mm wide, white, with pale tan to pallid brown-yellow over the center, and hemispheric, becoming planar and broadly umbonate. Its margin is smooth at first, becoming striate (with striations up to 3 mm long). The slime layer is colorless.
gills	The gills are free or narrowly attached to the stem, close, and white to somewhat yellowish. Transverse connections between adjacent gills are sometimes present. The short gills are not squarely cut off and are of several lengths.
stem	The stem is 45–65 × 3–6 mm, mostly white with an occasional yellowish tint near the bottom, cylindric, curvy, enlarged at base, and very viscid. In addition, it is solid. On the upper part of the stem is a glutinous collar, but it is hardly evident. There is a colorless slime layer covering the stipe below the last point of contact between the stipe and the expanding cap (i.e., the "glutinous collar," see above). The stem's flesh is white.
odor/taste	The odor is reported to be mild.
spores	The spores of this entity measure (4.9–) 5.6 – 7.0 (–8.4) × (4.0–) 4.9 – 5.6 (–6.3) µm and are globose (infrequently) to subglobose to broadly ellipsoid to ellipsoid (occasionally elongate) moderately densely covered with fine spine-like warts, and inamyloid. Clamps are common at bases of basidia.
discussion	Limacella subillinita was collected growing in grass in Mexico. The reader may wish to compare the present species with L. sp-Tulloss-8-31-94-E—a species commonly referred to "L. illinita" in central Mexico and SE Arizona, U.S.A.—R. E. Tulloss and N. Goldman

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 derived from the protolog and from original research of R. E. Tulloss and J. Geml. Macroscopic description from collector’s notes. Microscopic description by RET.

pileus

protolog: 15 - 55 mm wide, white to yellowish, with disc yellowish brown when dry, convex, slightly subumbonate, almost flat, glabrous, smooth, viscid or glutinous; context white; margin profusely striate; universal veil with color of gluten not recorded.

20–40 mm wide, white, with pale tan over disc, hemispheric, becoming planar and broadly umbonate; context ??; margin smooth at first, becoming striate (up to 3 mm); universal veil as colorless gluten pile.

lamellae

from protolog: free, ??, white, yellowish when dry, anastomosing.

adnexed, close, white; lamellulae attenuate, of several lengths.

stipe

protolog: 45 - 65 × 4 - 6 mm, uniform, white, pale yellowish (especially toward base) when dry, viscid; context white; universal veil with gluten probably colorless.

45–65 × 3–5 mm, color??, cylindric, sinuate, enlarged at base, very viscid; bulb ??; context solid (distinct central cylinder filled with sordid tissue in exsiccata), white; partial veil as superior glutinous collar, hardly evident; universal veil as gluten layer covering stipe below last point of contact between stipe and pileus (i.e., "glutinous collar," see above).

odor/taste

protolog: Odor agreeable. Taste not recorded.

Odor mild. Taste not recorded.

macrochemical
tests

none recorded.

pileipellis

absent.

lamella trama

bilaterial; w_cs = ?? µm; central stratum comprising interwoven filamentous undifferentiated hyphae 2.0–4.0 µm wide, ??.

basidia

26–32 × 6.5–7.5 µm, 4- and (occasionally) 2-sterigmate, with sterigmata up to 3.5 × 1.4 µm, arising from ??; clamps common to plentiful.

gluten layer

protolog: [gluten supporting?] hyphae 2.8 - 4.9 μm wide, thin-walled; clamps present.

On pileus: filamentous undifferentiated hyphae within gluten pile 1.4–3.8 µm wide, occasionally branching, with occasional narrowly clavate nonterminal segments; terminal cells of such hyphae 34–80 × 2.1–3.7 µm, with length/max.-width ratio = (9.7–) 11.3–25, with basal septa 0.8–2.5 (–3.0) µm wide, often curved, without obvious common orientation, not organized in fascicles, slanting upward, cylindric to narrowly clavate (and then only expanded very close to apex), with apex rounded, sometimes pale yellow, gelatinizing with aging of basidiome; clamps common. On stipe: filamentous undifferentiated hyphae frequent, but not crowded, arising from ??, branching rather sparsely, with segments and terminal cells much shorter than on pileus, eventually drooping (taking form suggesting epiphytic lycopods) and gelatinizing.

stipe context

longitudinally acrophysalidic; filamentous undifferentiated hyphae 1.8–4.5 µm wide, branching occasionally, dominating, with occasional slightly inflated intercalary elements; acrophysalides (e.g.) 38–108 × 5.5–10.2 µm, locally common, infrequent near surfaces; vascular hyphae 2.0–5.0 µm, rather common; clamps common.

partial veil

absent.

discussion

The fact that even in the youngest material, the terminal cells of the gluten retaining hyphae are not gathered in fascicles, are quite flexuous or whip-like, and are not entirely erect, suggests that this taxon differs from Zhuliangomyces sp-CMP0152, Z. illinitus (Neville and Poumarat 2004: 235) and var. argillacea, L. ochraceolutea (Neville and Poumarat 2004: 242), and L. ochraceorosea (Neville and Poumarat 2004: 249).

It should be considered that L. agricola may be a synonym of Z. subillinitus. If this were satisfactorily demonstrable, the name agricola (published in 1911) would have priority. The geographical location of the 1909 type collection of agricola, the color and striate margin of its fresh cap, the size-shape of its spores support the case for synonymy; however, the condition of the type of the older name may pose obstacles for making a sufficient case for synonymy. This issue requires further work. Based on limited available data, a sporograph comparison follows:

A sporograph comparison between the present species and the macroscopically similar Z. sp-CMP0152 is presented in the following figure:

The largest spores observed in the present species are probably produced by the 2-sterigmate basidia.

The U.S. collections were formerly presented on this site under a temporary code that is now abandoned—"L. sp-Williams-10-x-1995."

Spore data for collections
provisionally identified as: Zhuliangomyces subillinitus (Guzmán) Redhead

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.
