Amanita strobiliformis: The Ultimate Mushroom Guide
About The Amanita strobiliformis Mushroom
Amanita strobiliformis, often mistaken for Amanita citrina, the False Death Cap, is said by some authorities to be an edible fungus; however, there are reports that it may contain ibonetic acid or muscimol, in which case it is likely to be hallucinogenic if eaten, causing symptoms similar to those resulting from eating Amanita muscaria and Amanita pantherina.
This mushroom is associated mycorhizal with deciduous trees, preferring scattered forest, or woodland borders, usually on alkaline soil. It grows singular fruits and sometimes clusters. In Europe, it grows from the Mediterranean region to the Netherlands and England, and maybe further north.
Other names: Warted Amanita
Amanita strobiliformis Identification
The cap of Amanita strobiliformis is (50-) 70 - 150 (-220) mm wide, convex to plano-convex, sometimes with a flattened center, white to pale gray or pale brownish gray, with a nonsulcate, appendiculate margin. Thick remnants of white to pale gray or brownish-gray, (sub)floccose-felted volva form crusts, patches, or coarse, shapeless, to truncate-subpyramidal warts.
The gills are white to cream, crowded, and moderately broad. The short gills are obliquely truncate to attenuate.
The stem is 80 - 180 (-220) × 16 - 30 (-40) mm, about equal, mostly thickset, white, flocculose, with subfloccose-felted volval remnants forming one or more ridges, or rows of rather coarse, mostly shapeless warts. An apical annulus may be present at first, but it is soft, fragile, and evanescent. The stipe has a basal bulb that can be rather large (up to 80 × 50 mm).
The spores measure 10 - 13.5 (-14.5) × 7 - 8.5 (-9.5) µm and are amyloid and ellipsoid to elongate. Clamps are absent at bases of basidia.
Amanita strobiliformis Taxonomy & Etymology
This current name of this species dates from an 1866 publication by French mycologist Louis-Adolphe Bertillon (1821 - 1883), who transferred Agaricus strobiliformis Paulet ex Vitadd. to the Amanita genus. Synonyms include Hypophyllum strobiliforme (Paulet ex Vittad.) Paulet, and Agaricus strobiliformis Paulet ex Vittad.
Confusingly, in the past the synonym Amanita solitaria has been applied both to this species and to the quite similar but now generally accepted as a separate species Amanita echinocephala!
The specific epithet strobiliformis means shaped like a strobile - in other words, cone-like, as in fir cone or the reproductive organs of club mosses, with bract-like projections in a spiral pattern. One of the common names given to this species is 'European Pine Cone Lepidella' (Lepidella being a sub-grouping within the Amanita genus).
Amanita strobiliformis Look-Alikes
Rarely retains veil fragments on its cap through to maturity, the cap remains somewhat domed, its stem-ring is usually high up and not very substantial, and it does not have a sharp smell.
Occurs in a white variant, but it has flat veil fragments rather than warty ones, and it has a much smoother stem with a distinct persistent ring.
