Ciri dan struktur
The fruitbody of Macrolepiota clelandii has a cap that is initially egg-shaped, later becoming convex and then flattened in maturity, reaching diameters of 7.6 – 12.5 cm. It has a dark brown umbo and small dark brown scales that show the whitish flesh underneath. These scales are arranged in concentric rings that become increasingly crowded until the umbo, which is completely covered in scales. Small fragments of the partial veil may be left hanging on the cap margin. The white gills are free from attachment to the stipe and closely spaced. The slender, hollow stipe measures up to 18.7 cm long, and has a somewhat bulbous base. It has a pale brown colour, and features a ring on its upper half that often detaches to become freely movable up and down the stipe. The mushrooms have no distinctive odour. Its tall stature means the gills are usually clean, having avoided rain splash from the forest floor. According to Peter Roberts and Shelley Evans, all "parasol" species (i.e., M. procera and its close relatives, including M. clelandii) are edible. Anthony M. Young notes the similarity of M. clelandii to the edible European species M. konradii, but warns "the toxicity of the Australian species is unknown." Macrolepiota clelandii produces a white spore print. Individual spores are ellipsoid with a small germ pore, smooth, thick-walled, and measure 13.4–24.8 by 9.6–16.0 μm. They have a dextrinoid staining reaction (reddish-brown) with Melzer's reagent. The basidia (spore-bearing cells) are club-shaped, measuring 38.0–50 by 10.2–13.6 μm. They are two-, three-, or four-spored, with sterigmata up to 8.0 μm long.
Habitat dan peran ekologis
Macrolepiota clelandii fruits singly or in small groups on the ground in grass or among leaf litter. It is typically found in eucalypt forest and subtropical rainforests. It has been recorded from Queensland, New South Wales, Victoria, South Australia, and Western Australia. In southwest Australia it is found in jarrah (Eucalyptus marginata) and karri (Eucalyptus diversicolor) forests, where fruiting usually occurs in late autumn and early winter. The fungus appears to prefer disturbed ground, as it is often found at roadsides by forests, on lawns, grassy areas of parks, and among the slash of thinned karri regrowth forests. It is common in river red gum (Eucalyptus camaldulensis) woodlands. M. clelandii also occurs in New Zealand, where it is found in mixed mānuka (Leptospermum scoparium), kānuka (Kunzea ericoides), and kauri (Agathis) forest, and in conifer plantations. It is the smallest and most slender of the Macrolepiota species that occur there.

Reproduksi
Macrolepiota clelandii produces a white spore print. Individual spores are ellipsoid with a small germ pore, smooth, thick-walled, and measure 13.4–24.8 by 9.6–16.0 μm. They have a dextrinoid staining reaction (reddish-brown) with Melzer's reagent. The basidia (spore-bearing cells) are club-shaped, measuring 38.0–50 by 10.2–13.6 μm. They are two-, three-, or four-spored, with sterigmata up to 8.0 μm long. Collections with predominantly four-spored basidia will generally have smaller spores than those with two-spored basidia. Two-spored basidia produce spores with four nuclei. Cheilocystidia are plentiful on the edge of the gill. They have dimensions of 24.8–42.4 by 7.2–10.4 μm, with a cylindrical to club shape.
