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 isotype revision reports spores 7.2–8.4 × (4.8)5.6–6.4 × 4.8–5.6 µm, with subrhomboid to subhexagonal outlines in frontal view and ellipsoid to elongate outlines in lateral view. These are measurements of the examined type material. [ramirez-cruz-2013-types]
04Distribution and ecology
The type revision lists K. A. Thomas T319a (XAL, isotype), collected at Ponkuzhy, Wayanad District, Kerala, India, on 21 July 1999. Faces of Fungi separately records SDBR-CMUNK0448 from Phibun Mangsahan, Ubon Ratchathani, Thailand, collected on 4 May 2019 by N. Suwannarach and J. Kumla. These are specimen records, not a complete range. [ramirez-cruz-2013-types] [fof-10681-2026]

Ecological context
The Faces of Fungi treatment records its Thai collection on soil and describes habitat on dung or soil in meadows or open grassland. This later treatment is separate from the Indian isotype revision. [fof-10681-2026]
Occurrence records
Occurrence map — awaiting verified records
No occurrence points loaded.
Recorded observations are not equivalent to true biological range. Absence of records does not demonstrate absence of a species.
Occurrence provenance & future map methods

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 |
|---|---|---|---|
| No verified assay records entered. This does not establish that no published assays exist. | |||
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.
How chemistry records are structured ↗06Molecular evidence
This section has not yet been researched for this account.
07History
The name was published in Mycotaxon 83:196 (2002). The original description has not been inspected for this account. The 2013 revision compares the species with section Mexicanae despite its original placement in Cordisporae; that comparison is not a synonymy proposal. [ramirez-cruz-2013-types] [gbif-5459588-2026]
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
