Natal Super Strength (P. ochraceocentrata) — Spore Swab Cloud920®

About Psilocybe ochraceocentrata: The Species Behind Natal Super Strength

For two decades the market has sold this culture as "Natal Super Strength" or "Transkei." Bradshaw et al. formally described it as Psilocybe ochraceocentrata, a mushroom species from the Psilocybe family. The paper is in Proceedings of the Royal Society B, 2026 (DOI 10.1098/rspb.2025.2270). It is the closest known wild relative of Psilocybe cubensis. It is a separate species, not a cubensis strain. You get a swab captured under the correct species name. The cream caps carry the diagnostic ochre-yellow umbo. The prints are dark vinaceous-grey (grey with a wine-red tint) to purplish-grey for the scope. Also known as: Natal Super Strength (NSS). We keep the legacy trade name for continuity.

Psilocybe ochraceocentrata: Zimbabwean Type Specimen, South African Trail

Ochraceocentrata sits outside the cubensis Heritage or Hybrid framing. It is a wild-origin species from sub-Saharan Africa. The holotype is the original specimen scientists use as the reference for this species. It was collected in January 2013. The site was the Matobo Hills of Matabeleland South Province, Zimbabwe. The habitat was granitic sand in mixed deciduous woodland. More specimens were gathered across Zimbabwe and South Africa between 2013 and 2022. All were found on or near decomposing herbivore dung in Miombo woodland.

The 2026 paper by Bradshaw, Sharp, Van Der Merwe, Tremble and Dentinger showed something important. Publicly stored "P. natalensis" NSS sequences actually cluster with ochraceocentrata. That resolves a 20-year misidentification. It also showed that ochraceocentrata and P. cubensis last shared a common ancestor about 1.56 million years ago (95% HPD: 0.71–2.55 Mya). The species name is Latin: ochraceo (ochre-yellow) plus centrata (centre). That points directly at the diagnostic yellow umbo on the cap.

Psilocybe ochraceocentrata: Look and Spore Print

The single most useful field feature under the scope is the ochre-yellow umbo. This is a raised, fulvous central area on the cap. It sets ochraceocentrata apart from both P. cubensis and true P. natalensis. Caps run cream to pale vinaceous-grey (grey with a wine-red tint). They have a pale straw-yellow margin. They start dome-shaped, then flatten out with age. The edge is often wavy with a fine radial silky sheen. Stems bruise blue-green instantly where handled. This is called glaucous bruising — a blue-green colour on any touch or damage.

Under the scope, spores are ellipsoid to lenticular. They measure around (11)11.8(12.5) × (6.5)7.6(8.0) µm. They are thick-walled with an apical germ-pore. That is a tiny opening at the tip of the spore where new mycelium grows out.

Six anchors:

• Cap colour: cream to pale vinaceous-grey (grey with a wine-red tint).
• Cap centre: ochre-yellow to fulvous. Margin: pale straw-yellow.
• Cap shape: starts dome-shaped, then flattens with age. Often wavy.
• Surface: finely radially silky with a dull sheen.
• Cap size: up to 65–75 mm across in the wild type. Medium-large in cultivation.
• Stem: up to 95 mm long, 9–10 mm wide. Cream to white.
• Stem shape: cylindrical, often twisted. Hollow with fibrous walls.
• Bruising: instantly blue-green (glaucous) on handling or damage.
• Spore print colour: dark vinaceous-grey (116) to purplish-grey (128).
• Spores: ellipsoid to lenticular, about 11.8 × 7.6 µm, with apical germ-pore.

Cultivation Profile of Psilocybe ochraceocentrata

This cultivation data is here only as reference for identification. It shows how the strain behaves in a lab.

Under lab conditions, ochraceocentrata is described as easy to moderate. Colonisation is very fast. Visible mycelium appears in 3–5 days from liquid culture. That is 15–20% faster than average cubensis. The mycelium is strong and rope-like — thick strands, a sign of strong genetics. It resists contamination well. Fresh air exchange needs to run a bit higher than for cubensis. No casing layer is needed. Pins form reliably without one.

Numbers from the shop's own culture line and community reports:

• Growth speed: very fast. Visible mycelium in 3–5 days. 15–20% faster than average cubensis.
• Best temperature: 22–24°C for fruiting. 24–27°C for colonisation. Also colonises down to ~15.5°C, but slower.
• Colonisation window: about 12–16 days colonisation plus 5–7 days pinning.
• Recorded flushes: 3–4.
• Yield: high. Dense clusters and large wavy fruits with the diagnostic ochre umbo.
• Difficulty: 2/5. Easy to moderate. The fastest, most forgiving variety in the Cloud920 catalogue.
