Amanita chlorophylla

Amanita chlorophylla is an agaric with green gills and cap cream with greenish hue. Very close to A. austroviridis, and similarly found under Allocasuarina, in Vic and NSW. RARE.

Common Name: None

This is an interesting species because of the distinctly green lamellae and the clearly greenish spore print. It also is characterised by a fragile annulus, no volva, elongate spores, narrow marginal cells and velar remains a mixture of inflated cells and hyphae. It is also of note as most collections were found under a pure stand of Allocasuarina littoralis for which there are few records of ectomycorrhizal fungi. It is clearly related to A. austroviridis, but that species differs in having an olive-buff pileus, olivaceous grey universal veil, more stocky habit, and a white spore print. Otherwise, there is no close species in any related flora.

Pileus
Up to 9 cm diameter, convex then plane, smooth dry, not pellucid-striate, dull white to pallid cream, with slight but distinct greenish hue (9E2-10F4-20B1-G/H1), with velar remains as fairly large, flat soft membranous scales, cream to warm buff,margin appendiculate;
Lamellae
Free, thin, crowded, one or two series of lamellulae, bright to greyish lime-green, margin paler to almost white;
Stipe
Firm with bulbous base, long (to 12 cm) and fairly narrow (to 1.5 cm), off-white to pale green with fine fibrillose hairs throughout, and some scattered bands below annulus fragile and often present as fragments, fragile, membranous, flared, warm buff or green, not striate, base bulbous to turbinate, with no volva, but with warm buff coloured zones on the upper portion.
Smell
Unremarkable.
Spores
Elongate, 9.3-11.4 (11.7) ? µm x 5.4-6.6 (6.9) µm , Q 1.65-1.87, amyloid, sometimes weakly so, basidia 45-55 ?11-15 µm, sub basidial cell only very slightly inflated, subhymenial cells only a little inflated, clamp connections frequent on all hyphae, including velar remains; marginal cells abundant, clavate to pyriform 20-35 ? 12-17 µm, velar remains a mixture of inflated cells and filamentous hyphae, mostly somewhat wider, in mostly equal proportions, inflated cells 40-50 µm, hyphae 8-10 µm. Spore print pale greenish cream.
Habitat
Mostly under Allocasuarina.
