Family: Penis Envy family

Origin

Sources give differing accounts: mushrooms.support calls it a Mississippi landrace isolation; Mind Mend says it was discovered and cultivated in 2011 from a wild Mississippi variant. No person is credited.

Lineage

Conflicting claims: Culture Cave quotes a vendor describing it as a cross of Penis Envy and Blue Magnolia, while mushrooms.support describes it as a Mississippi landrace isolation.

Appearance

One source describes thick, dense stipes and blue cap margins, with cap and gill coloration listed as steel blue and tan. Cap size and spore-print color are not specified for this variety.

Cultivation

mushrooms.support lists a 22–25°C fruiting range and rye grain with CVG as preferred substrate; these are source-reported specifications.

Reported effects

Mind Mend describes reported effects as warm and uplifting, with positivity and a gentle mood boost. These are subjective reports, not established effects specific to the variety.

Good to know

Culture Cave lists Steel Magnolia research plates and liquid culture from vendors in the United States and Australia.

Lab results

mushrooms.support reports an HPLC dry-weight total alkaloid payload of 14.4 mg/g, including 12.2 mg/g psilocybin and 1.8 mg/g psilocin. These figures are claims from that source.
