name	Limacella quilonensis
name status	insufficiently known
author	A. V. Sathe & Jeys. Daniel
english name	"Quilon Slimy Stem"
intro	The following is based entirely on the original description of Limacella quilonensis.
cap	The glutinous and sticky cap of L. quilonensis is 50 -90 mm wide, white, and becomes pale yellow with age. It is globose at first, then hemispheric, and finally convex in age. The cap's flesh is white to pale yellow and 12 mm thick. The cap's margin is not striate and slightly inflexed when young. The layer of gluten on the cap is probably colorless.
gills	The 7 - 9 mm broad gills of this species are adnexed, distant, and white at first. The are described as turning to cream in age. While the edge of the gills is said to be fertile (as in all limacellas), it is also described as "serrate." The short gills are said to have at least three lengths.
stem	The originally white stem is 120 - 140 × 12 - 15 mm and turns pale yellow with age. It is solid, cylindric, glutinous and sticky, and has a bulb up to 20 mm wide. There is a membranous, white, superior ring on the stem as well as a colorless layer of gluten.
odor/taste	The odor of the species is said to be nauseating and rotten. Understandably, no taste was recorded for this species.
spores	The authors report that the spores of this species measure 7.0 - 10.0 × 7.0 - 8.5 μm, which suggests that they are globose to subglobose to broadly ellipsoid. In addition they are said to be slightly dextrinoid. Clamps are present at bases of basidia.
discussion	There are some reasons to doubt that the present taxon belongs in Limacella sect. Lubricae: The spores are much larger than those reported for any other species in the section. Microscopic characters illustrated for the species in the protolog are unlike those of all other known taxa in the section. The original description does not clearly establish that the species belongs in the Amanitaceae. It will be important to review any extant material of this species.—R. E. Tulloss

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 based entirely on the protolog of the present species.

pileus

from protolog: 50 -90 mm wide, white, becoming pale yellow with age, globose at first, then hemispheric, becoming convex with age, glutinous and sticky; context white to pale yellow, 12 mm thick, fleshy, not confluent with stipe; margin entire, non-striate, slightly inflexed when young, becoming plane with age, ?appendiculate; gluten layer ?colorless.

lamellae

from protolog: adnexed, distant, white turning to cream with age, ?fleshy, 7 - 9 mm broad, with ?serrate edge; lamellulae in at least three "sets."

stipe

from protolog: 120 - 140 × 12 - 15 mm, white turning to pale yellow with age, cylindric, glutinous and sticky; bulb up to 20 mm wide; context fleshy, solid; partial veil membranous, white, superior; gluten layer ?colorless.

odor/taste

from protolog: Odor nauseating, rotten. Taste not recorded.

macrochemical
tests

none recorded.

pileipellis

absent.

pileus context

from protolog filamentous hyphae thin-walled hyaline, branched, 4.0 - 21.0 µm wide; clamps plentiful. [Note: Since the protolog does not mention acrophysalides or inflated cells in this tissue, it is possible that widths of acrophysalides or vascular hyphae are included in the above dimension range.—ed.]

lamella trama

from protolog: bilateral in young specimen becoming slightly irregular with age; filamentous hyphae 3.5 - 6.0 µm wide, branched, thin-walled, hyaline; inflated cells to 15.5 μm wide, ?intercalary; clamps plentiful.

subhymenium

from protolog: cellular, "poorly developed."

basidia

from protolog: 42 - 54 × 12.0 - 14.5 μm, 4-sterigmate, clavate, cyanophilic, with sterigmata 3.5 - 6.0 μm long; clamps plentiful.

gluten layer

from protolog: On pileus: elements erect; filamentous hyphae hyaline, thin-walled; clamps plentiful.

stipe context

from protolog: filamentous hyphae thin-walled, hyaline, 5.0 - 26.5 µm wide; clamps plentiful. [Note: Since the protolog does not mention acrophysalides or inflated cells in this tissue, it is possible that widths of acrophysalides or vascular hyphae are included in the above dimension range.—ed.]

partial veil

not described.

lamella edge tissue

from protolog: fertile.

basidiospores

from protolog: [-/-/-] 7.0 - 10.0 × 7.0 - 8.5 μm, (L = 8.5 μm; W = 7.5 μm; est. Q = 1.0 - 1.18; Q = 1.10), hyaline, [colorless,] smooth, thin-walled, cyanophilic, weakly dextrinoid; apiculus "central" [undoubtedly an error—ed.]; contents not reported; white in deposit.

ecology

Solitary. On soil.

discussion

While it does seem probable that the species described above belongs in Limacella sect. Lubricae, strictly speaking, the information provided in the protolog does not establish that this species belongs in the Amanitaceae—acrophysalidic tissues are not mentioned.

The form of the "trichodermial palisade" illustrated in the protolog is not suggested by the text which says simply, "epicutis of erect, hyaline and thin walled hyphae." The cells in the illustration could be described as a "chain" of two narrowly ventricose cells. This suggests a similarity to the cells in the volva of Amanita subsect. Vittadiniae—the most basal group in the genus Amanita. It will be very important to revise the type if it is in sufficiently good condition.

The spores of this species are by far the largest of any reported from sect. Lubricae.

It will be important to review any material of this species that may exist.

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.
