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. | ||||||||||||||||||||||||||||||||||||||||

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 | 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. | ||||||||||||||||||||||||||||||||||||||||

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.

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. ...more... | ||||||||||||||||||||||||||||||||||||||||

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.
