intro | The information below is based on an interpretation by RET of the original description of Corner (1994a). |
cap | The cap of L. singaporeana is 30 – 50 mm wide, pale brown-bister, deeper brown toward the dark-rusty center disc, and pale buff-flesh-colored toward the margin. The cap is convex then plane, umbonate, smooth, and opaque. The cap's flesh is 3 – 5 mm thick above the stem, dry, rather soft, and pale buff-flesh-colored to nearly white. The cap probably bears a gluten layer. |
gills | The gills are nearly free, crowded, and dingy cream to pale buff-flesh colored. On a small sample of fruiting bodies, Corner counted 30 – 40 "primaries." The short gills are in 2–3 ranks. |
stem | The solid, ringless stem is 40 – 60 mm long, 3 – 4 mm wide at the top, white at the top, otherwise pale buff-flesh-colored, slender, and with a fibrillose surface. The stem is cottony or scurfy at the top and becomes subviscid in the lower part. At the stem's base, there is a narrow bulb, 4 – 5 mm wide, that is white and covered with small hairs. |
odor/taste | not reported. |
spores | Corner reported that the spores measure 4 – 5 × 3 – 3.5 µm and are finely warted, subglobose to broadly ellipsoid and inamyloid. Clamps were found in other tissues and, therefore (Bas 1969), are probably present at bases of basidia. |

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. This description is based on the editor's interpretation of the protolog. | ||||||||
pileus | from protolog: 30–50 mm wide, pale brown-bister, deeper brown toward fuscous-ferrugineous disc, pale buff-flesh colored toward the margin, convex then plane, umbonate, smooth, opaque; context 3–5 mm thick over stipe, dry, rather soft, pale buff-flesh colored to nearly white; margin not described; gluten layer described as "viscid." | ||||||||

discussion |
Cells called "cystidia" on the stipe surface are probably superficial acrophysalides as they are described as terminal and clavate and slightly smaller than the smallest acrophysalides of the stipe context: "up to 45 × 12 µm, clavate, scattered." See the very similar L. asperulospora, also described from Singapore. Also, L. taiwanensis was compared by its authors to the present species. | ||||||||

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.
