03Taxonomic description
Taxonomic description. These characters are presented for scientific reference and are not intended as field-identification guidance.
Macroscopic characters
This section has not yet been researched for this account.
Microscopic characters
The holotype revision reports spores 6.4–8.0(8.8) × 4.8–5.6 × 4.0–4.8 µm and a partly gelatinized pileipellis. These are selected type observations. [ramirez-cruz-2013-types]
04Distribution and ecology
M. R. Sánchez-Jácome 1163 (IBUG, holotype) was collected on 27 September 2005 at Neverías, Sierra de Cacoma, Jalisco, Mexico. This locality does not delimit the species’ range. [ramirez-cruz-2013-types]

Ecological context
The holotype came from pine–oak forest at 2,200 m. Broader ecology remains pending. [ramirez-cruz-2013-types]
Occurrence records

Future ingestion will review licensing, coordinate uncertainty and sensitive locations. Sampling, clustering and date filters will operate on separately loaded datasets; no coordinates are embedded in this page.
05Chemistry
Measurements belong to studies, specimens and methods. A single concentration cannot stand in for a species.
| Study / year | Material | Method | Record |

Fields retained in each future assay record
Study, publication year, specimen, material, sample size, provenance, analytical method, preparation, storage, psilocybin, psilocin, baeocystin, norbaeocystin, aeruginascin, units, qualifiers and methodological notes. No concentrations have been invented for this prototype.
Modern quantitative assays
Modern analytical studies have not yet been systematically searched and checked for this account.
Evidence assessment
Chemical literature has not yet been reviewed for this account. No assay values are extracted; this does not establish compound presence or absence.
Assessments depend on material, preparation, storage, sampling and analytical methods. Measurements are literature records, not predictions of effects.

A place for the historical record
This account records the nomenclatural history checked so far. Broader historical research remains pending; interpretations must stay connected to their documentary sources.
08Conservation
This section has not yet been researched for this account.
- Assessment status
- Not yet researched
- Assessment authority / year
- Not verified / Not verified
Not researched by Psilocybia, not assessed by a conservation authority, and Least Concern are different states. None should be inferred from another.
09Images & specimens
Space is reserved for field photographs, herbarium specimens, microscopy and historical plates, with source and licence metadata.
Photographs are not presented as sufficient for mushroom identification.

Conflicting evidence
GBIF retains an older family classification.
Adopt Niskanen et al. (2026), which includes Psilocybe in Agrocybaceae; use GBIF only to corroborate nomenclature and species acceptance. — Codex (agent), 2026-09-13
