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.

NOTE: Spore data from papers by Z. L. Yang are presented following his use of the "Times New Roman" face for "Q" and "Q'"—respectively, "Q" and "Q."

This description is based on the protolog with some editing by RET.

pileus

from protolog: 35–65 mm wide, blackish brown [6F6–8; Raw Umber, Brussels Brown, Warm Sepia] over disc, becoming brownish yellow to yellow [3A4–6, 4A4–6; Buff-Yellow to Light Cadmium] towards pileal margin, convex to plano-convex, sometimes umbonate, smooth, glutinous; context ??; margin nonstriate; gluten layer present.

lamellae

from protolog: free, crowded, white to whitish; lamellulae attenuate to rounded-attenuate, evenly distributed.

stipe

from protolog: 50–90 × 5–10 mm, white to brownish, subcylindric, farinose at apex, becoming fibrillose and subviscid in lower part; bulb as slightly swollen to subglobose stipe base, 7–15 mm wide; context fistulose; exannulate; gluten layer not described.

odor/taste

not recorded.

macrochemical
tests

none recorded.

pileipellis

See description of "hypodermium" below in "gluten layer" data field.

lamella trama

from protolog: bilateral; w_cs = 30–50 µm; central stratum with filamentous undifferentiated hyphae 2–7 µm wide, abundant to fairly abundant and subfusiform to ellipsoid [intercalary??] inflated cells (70–90 × 10–20 µm); subhymenial base with angle of divergence 30°–45° (–60°), with filamentous undifferentiated hyphae 2–7 µm wide and inflated cells (fusiform to ellipsoid, 60–90 × 12–20 µm) [terminal?? intercalary??]; vascular hyphae rare.

subhymenium

from protolog: 30–40 (–50) µm thick, with 2–3 (–4) layers of subglobose to ellipsoid to irregular or branching inflated cells (10–20 × 8–17 µm) occasionally mixed with barely inflated elements 3–7 µm wide; with basidia arising from cells of all forms.

basidia

from protolog: 20 - 30 × 5 - 6.5 µm, 4- or (rarely) 1-sterigmate, with sterigmata 2–3 (–4) µm long; clamps frequent.

gluten layer

from protolog: On pileus: gluten pile 70–120 µm thick; gluten-supporting filamentous undifferentiated hyphae erect, colorless or with yellowish brown vacuolar pigment, sometimes finely encrusted, frequently septate, frequently branching, subcylindric, arising from dense upper layer of pileus context ("hypodermium" of the authors) 10–30 µm thick (of compacted, subradially arranged filamentous undifferentiated hyphae 2–5 µm wide, colorless or sometimes with yellowish brown vacuolar pigments); terminal cells subcylindric to narrowly clavate, 30–70 × 2–7.5 µm; clamps frequent.

stipe context

from protolog: longitudinally acrophysalidic; filamentous, undifferentiated hyphae 3–20 µm wide; acrophysalides 150–250 × 15–45 µm, thin-walled, hyaline, colorless; vascular hyphae rare; clamps frequent.

partial veil

absent.

lamella edge tissue

fertile?

basidiospores

from protolog: [40/2/1] (3.0-) 3.5 - 4.0 (-4.5) × 3.0 - 3.5 µm, (Q = (1.0-) 1.09 - 1.25; Q = 1.14 ± 0.06), hyaline, colorless, thin-walled, verruculose, inamyloid, globose to subglobose to broadly ellipsoid, adaxially flattened; apiculus proportionately large; contents not reported; color in deposit not reported.

ecology

from protolog: As a pair, at 1600 m elev. On soil.

TAIWAN: Hsinchu Co. - Ssumakussushan, 25.v.1994 W.N. Chou 00475 (holotype, TNM-F0002190).

discussion

from protolog: "Limacella taiwanensis is characterized by its brownish yellow to yellow pileus with a blackish brown disc, a subviscid stipe with a subglobose base, the absence of an annulus, and small, verruculose basidiospores. It belongs in the section Limacella (Singer 1986). Limacella taiwanensis may be related to L. singaporeana Corner (1994). However, L. taiwanensis differs from the latter by its stouter basidiome with a differently colored pileus, proportionally shorter spores, and thicker pileipellis [i.e, universal veil—ed.]. Limacella ochraceolutea P.D. Orton (1969), originally described from Europe, somewhat resembles L. taiwanensis, but the former has much more strongly viscid pileal and stipe surfaces with a significantly paler colored pileus, a non-bulbous base of stipe, and somewhat longer basidiospores with a higher Q’ (Orton 1969, Breitenbach & Kränzlin 1995)."

For purposes of comparison, the sporograph (red figure) of L. singaporeana (with estimated Q values) is presented here.

For purposes of comparison, the spore data for L. ochraceolutea from (Neville and Poumarat 2004) (excluding the measurements for "globose spores" that Neville and Poumarat give separately) is presented here as the larger green figure, with the spore data (smaller green figure) from Orton's protolog of L. ochraceolutea with RET's est. values of Q.

Spore data for collections

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.
