holotypes

VPI VTMH-555

intro

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 information relies entirely upon the protolog of the present species.

from protolog: The basidiome of A. pseudoinculta is secotioid. The species was discovered and described during the revision of the genera Amarrendia and Torrendia by Justo et al. (2010).

pileus

from protolog: 4 - 10 mm broad, hemispheric, sometimes slightly depressed at center at maturity, not disintegrating; context white; universal veil as patches in young specimens.

peridium

from protolog: up to 0.7 mm thick, smooth or granular, whitish.

gleba

from protolog: at first subgelatinous, divided into numerous irregular locules, whitish.

stipe

from protolog: 10 - 35 × 2 - 7 mm, cylindric or narrowing slightly downward, whitish, usually covered with fibrils and/or scales; context white; universal veil saccate, membranous, whitish.

odor/taste

from protolog: Odor and taste indistinct.

macrochemical
tests

none reported.

peridium micro

from protolog: not gelatinized, layered; with lower layer including inflated cells globose to ovoid to irregular, up to 35 (-45) μm wide; filamentous undifferentiated hyphae 2.0 - 10.0 μm wide, [perhaps in both observed layers?? or only in the upper layer??—ed.].

hymenial trama

from protolog: vascular hyphae present.

subhymenium

not described.

basidia

from protolog: 20 - 60 × 10 - 16 μm, dominantly 4-, occasionally 2-sterigmate, thin-walled; clamps present.

universal veil

from protolog: filamentous undifferentiated hyphae 2 - 6 μm wide, densely interwoven; inflated cells globose to ovoid to irregularly shaped, 20 - 75 × 20 - 65 μm; clamps present.

[It is not stated whether the tissue studied was from a patch on the peridium of the cap or was from the saccate volva.—ed.]

stipe context

from protolog: filamentous undifferentiated hyphae 4 - 20 μm wide; acrophysalides cylindric to clavate 45 - 150 × 10 - 40 μm; vascular hyphae present; clamps present.

basidiospores

send to graphing tool

from protolog: [120/8/4] 11.3 - 19.0 (-19.5) × 5.2 - 7.3 (-8.0) μm, (L = 13.1 - 15.6 μm; W = 6.0 - 6.5 μm; Q = 1.80 - 2.90; Q = 2.05 - 2.48), inamyloid, elongate to cylindric; apiculus broad, apically centered.

ecology

from protolog: On sandy soil near Allocasuarina humilis and Eucalyptus.

material examined

from protolog: AUSTRALIA: WESTERN AUSTRALIA—Shire of Dandaragan - Mullering Brook, Brand Hwy., ca. 206 km N of Perth, 3.vii.1991 L. & M. Bailey & O. K. & H. H. Miller [O. K. Miller 25066] (holotype, VPI VTMH-555), [O. K. Miller 25094] (paratype, VPI VTMH-366), [O. K. Miller 25070] (paratype, VPI VTMH-558), H. H. Miller s.n. [O. K. Miller 23825] (paratype, VPI VTMH-411).

discussion

For the time being, especially because of the author's view that the most closely related known taxon is Amanita inculta, in these pages, the present taxon will be placed in Amanita stirps Grandis.

Spore data for collections
provisionally identified as: Amanita pseudoinculta Justo

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.
