Overview
Cleland’s Parasol (Macrolepiota clelandii) is a tall and majestic basidiomycete fungus native to the native eucalyptus bushlands of southern and eastern Australia. Named in honor of the pioneer Australian mycologist Sir John Burton Cleland, this handsome mushroom is celebrated for its towering, slender form, broad umbrella cap patterned in dark-brown concentric scales, and a double-membraned ring that slides freely along its patterned stem.
Biology and Physical Characteristics
Macrolepiota clelandii produces large, umbrella-shaped caps that can span over six inches across. The cap surface begins as an intact dark brown covering that fractures into delicate concentric brown scales (squamules) as the cap expands, revealing a pale cream fibrous background underneath. Beneath the cap, dense, free white gills yield abundant hyaline, dextrinoid elliptical basidiospores. Its stipe is exceptionally tall and slender, terminating in a bulbous base and decorated with fine brown zig-zag or snakeskin banding beneath a complex, movable annular ring.
Behavior and Ecology
Operating as a primary saprotroph in native dry and wet sclerophyll forests, the mycelium of Cleland’s parasol spreads through sandy loam enriched with decaying eucalyptus leaves, shed stringybark, and woody humus. Fruiting occurs during late summer and autumn following substantial soaking rainstorms. As the tall cap unfurls well above ground-level detritus, circulating woodland breezes efficiently carry spores across the forest floor to colonize new forest clearings.
Conservation and Human Impact
The species is abundant, widespread, and categorized as Least Concern across its native Australian range. While well protected within national parks and forestry reserves, it remains sensitive to frequent, high-intensity bushfires that incinerate organic soil litter layers. Maintaining natural fire intervals and preserving native sclerophyll woodlands supports thriving wild populations.
Interesting Factoid
The delicate ring on the tall stem of Cleland’s parasol is completely unattached to the stipe at maturity, meaning you can gently slide it up and down the stem like a tiny wooden bracelet.
