Derrumbes, Landslide mushroom

Psilocybe caerulescens, commonly called the “landslide mushroom” or “derrumbes”, meaning “collapse” in Spanish, is a bluish bruising psychedelic fungus that has the tendency to grow on disturbed or cultivated grounds. With its silvery-blue metallic glow, this very expressive specie undergoes considerable variation in cap color and shapes and can grow to impressive sizes.

Alongside Psilocybe aztecorum, P. caerulescens is believed to be one of the probable candidates reported in the manuscripts of Spanish explorer Bernardino de Sahagún when referring to teonanacatl or the “flesh of the gods” by the Aztecs. Along with its entheogenic qualities, it is also a medicinal fungus that is said to have anti-viral properties.

Thirteen pairs of this potent specie were ingested by R. Gordon Wasson during a Velada ceremony guided by renown Mazatec healer Maria Sabina. Since the mushroom grows in that regions, it is also called Psilocybe caerulescens var. mazatecorum.

After centuries of shamanistic use by the great ancient civilizations of Mexico, this medicinal and neurotropic mushroom has yet to unravel its full potential for wellness use.

To this day, it is consumed by the Mazatec shamans to heal and travel within and is considered to be a good entry-level specie for psilocybin experiences.

Potency Description

Moderately to highly active. Analyses from aged specimen show low levels of 0.20% psilocybin, 0% psilocin.

Habitat Origin

Widespread throughout central regions of Mexico, Venezuela and Brazil. Rarely solitary, found in the late spring and summer on disturbed grounds, preferring muddy orangish brown soils, devoid of herbaceous plants. Originally found in Montgomery and Alabama in 1923 by Murrill and not redescribed from that area since. Found in South Carolina in 2008, believed to be widespread throughout North Georgia.

Strain Effects

It is considered to be a good entry-level specie for psilocybin experiences. Velada, which means evening in Spanish, is a sacred ceremony mediated by healers or curanderas/curanderos. The mushrooms are consumed in pairs to symbolize the universal duality, and only at night, under the safe veil of the darkness. In his article "Seeking the Magic Mushroom", Wasson described an "out of body experience" with intense visuals and vibrating bodily sensations. He also said that the next day, he felt clear-headed and changed, what we may call the after-glow.
