The Australian Strain, aka Psilocybe australiana is a species of psilocybin-producing Psilocybe cubensis originally reported from Southern Australia (New South Wales). This mildly potent strain is a popular candidate amongst amateur mycologist and psychonauts and can be found growing naturally in rich woody grounds often beneath Eucalyptus and Nothofagustrees. Psilocybe authority Paul Stamets explains that the extensive, commercial timber plantations using Pinus radiata have created an extensive ecological zone in which this species flourishes. Actually, more recently, the Australian Strain magic mushroom is even being associated with gardens as it is noticed flourishing in wood debris around homes or wood chips commonly used in landscaping.

Favouring temperate forests,  the Australian Strain magic mushroom is also reported from Victoria, Western Australia, Tasmania and New Zealand. Originally discovered by Mexican Psilocybe expert Gastón Guzmán Huerta and Roy Watling and classified as psychoactive, this bluish-bruising species shows a tight taxonomic relationship to Psilocybe subaeruginosa and P. eucalypta.

Visual Description

• Cap: 1.5-3 cm broad. Convex to subcampanulate, with a slight umbo and sometimes with a sharp, short nipple. Surface smooth, viscid when wet, often with veil remnants around cap margin. Coloration is light orangish brown, darker at apex, lighter at margin. Hygrophanous, fading to yellowish brown in drying. Flesh often bluing around cap margin. In age, margins may wave and lift. • Gills: attachment adnate. Color is olive yellow, turning dark purplish brown in maturity. Spacing very dense. • Stem:45-110 mm long by 2-3 mm thick. Equal, slightly larger at base. Coloration is dingy brown, bruising bluish when handled. Partial veil often leaving a fragile annular zone where we can observe a dust of black spores. • Spore print: dark purplish brown. • Microscopic features: 12-14 by 6-8 µ. • Taste and odor: said to be farinaceous.

Potency Description

Moderately active, said to be rather mild. < 0.25% psilocybin.

Habitat Origin

First documented in Southern Australia (New South Wales), near Sydney; also reported from Victoria, Western Australia, Tasmania and New Zealand. Favouring rich woody debris from Pinus radiata, often found growing on branches beneath Eucalyptus and Nothofagus trees. Fruiting season April along road sides, trails, in tree plantations and in wood debris around homes.

Strain Effects

Hallucinogenic effects said to include euphoria, visual stimulation with slight tracing effects.
