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 8.0–8.8 × 5.6–7.2 × 4.2–5.6 µm, subhexagonal to subrhomboid in frontal view and ellipsoid in lateral view, and a subgelatinized cutis. The revisers note smaller spores than the measurements they attribute to the original description, 8.0–9.5(11.0) × 6.5–7.0(8.0) × 5.5–6.0(6.5) µm. The original paper has not been inspected here; these ranges are kept as source-specific observations and are not pooled. [ramirez-cruz-2013-types]
04Distribution and ecology
The revision lists K. A. Thomas T-320a (XAL, holotype), collected on 21 July 1999 at Muthanga, Wayanad District, Kerala State, India. This is the provenance of the examined material, not a range boundary or an endemicity claim. [ramirez-cruz-2013-types]

Ecological context
Habitat and substrate literature has not yet been checked for this account. The type locality alone does not establish ecological preferences.
Occurrence records
Recorded observations are not equivalent to true biological range. Absence of records does not demonstrate absence of a species.
Occurrence provenance & map methods
- Licence / retrieval date
- CC BY-NC 4.0 / 2026-09-15
- Coordinate uncertainty
- Reported for 3 of 3 plotted records. Median 31 km; 0 records at 30 m or finer; coarsest 68 km. Points are plotted at source precision, so precision varies by orders of magnitude within this map.
- Sensitive records
- unreviewed
- Countries with georeferenced records
- IN (3)
Points are plotted at source precision on an equirectangular projection. Two records falling on the same rendered pixel appear as one mark; the downloadable dataset is not reduced. Records published under names this reference has not reconciled, including synonyms, infraspecific taxa and sequence clusters, are excluded rather than reassigned.
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 83:198 (2002). The 2013 holotype study supplemented microscopic observations and reported smaller spores. The original 2002 paper remains unchecked in this account. [ramirez-cruz-2013-types] [gbif-5459287-2026]
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
Conservation assessments have 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.

- content: verified · 2026-09-29 · Psilocybia editorial. Verification source
The archive was read row by row to generate the published maps and the per-country counts. 31,208 rows carry usable coordinates and a taxonKey this reference maps to one of its own records; 231 rows fall under synonyms, infraspecific taxa or sequence clusters and are excluded rather than reassigned. Coordinate uncertainty is reported for about 90 per cent of rows, with a median near 7 km and a coarsest value above 5,000 km, so individual points vary enormously in precision. 25 per cent of the country entries derived from this download rest on a single record, and the majority of records are human observations rather than preserved specimens; counts are therefore published alongside every country.

Taxon record retrieved and confirmed by two independent routes: a name query returned exactly one active species taxon named Psilocybe wayanadensis with id 1227726, and the record endpoint was then fetched directly and agreed on name, rank and active status. This is an identifier for a community observation platform, not a taxonomic authority.

Database identifiers for this species, recorded so a reader can retrieve the same records. The GBIF backbone still places Psilocybe in Hymenogastraceae, whereas this site follows the 2026 family revision and treats the genus in Agrocybaceae; citing the identifier is not an endorsement of that placement.
