Taxonomy: acceptedChemistry: Not yet researchedMolecular data: Not yet researched

Scoped account prepared by the Psilocybia editorial process. Macroscopic descriptions, chemical literature, conservation, licensed scientific imagery and occurrence datasets remain unresearched. Original protologues and exhaustive synonymy remain incomplete. Type observations and study localities are not complete species descriptions or range maps.

01Overview

Source-checked

This Colombian account centres on the 2013 re-examination of type material. It documents selected microscopic features and the collection provenance, while chemical evidence and broader ecology remain unresearched. [ramirez-cruz-2013-types]

This is a scientific reference record, not field-identification guidance.

Human reviewed — J Dale, 2026-09-29

Name and acceptance checked in the Kew Colombian Fungi record and 2013 type revision. Family discrepancy explicitly resolved using the 2026 primary treatment. Direct Index Fungorum retrieval and original protologue remain incomplete; its identifier is not populated from an uninspected name record.

03Taxonomic description

Taxonomic description. These characters are presented for scientific reference and are not intended as field-identification guidance.

Macroscopic characters

Not yet researched

This section has not yet been researched for this account.

Microscopic characters

Source-checked

The examined material has reported spores of 5.6–7.2(8.0) × 4.0–4.8 × 3.2–4.4 µm. The revision records pileocystidia embedded in the ixocutis, a ramose subhymenium and setaceous hyphae in the basal mycelium. These are selected observations from the specimen labelled an isotype in the paper. [ramirez-cruz-2013-types]

04Distribution and ecology

Source-checked

The revision lists G. Guzmán 35331 (XAL, isotype), collected on 24 September 2002 at Pacurita, southeast of Quibdó in Chocó, Colombia. This locality is specimen provenance; it does not delimit the species’ range. [ramirez-cruz-2013-types]

Occurrence records

No georeferenced records located

The occurrence search returned no georeferenced records for this name. This is an absence of records, not evidence of absence.

Recorded observations are not equivalent to true biological range. Absence of records does not demonstrate absence of a species.

Sensitive records
unreviewed

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.

Published assays · Measurements retain their original methodological context.
Study / yearMaterialMethodRecord
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

Not yet researched

Modern analytical studies have not yet been systematically searched and checked for this account.

Evidence assessment

Not yet researched

Chemical literature has not yet been reviewed for this account. No assay values are extracted; this does not establish the presence or absence of any compound.

Assessments depend on material, preparation, storage, sampling and analytical methods. Measurements are literature records, not predictions of effects.

07History

Source-checked

The name is attributed to Guzmán, M. Torres and Ramírez-Guillén, published in International Journal of Medicinal Mushrooms 6(1):86 (2004). The 2013 type revision adds microscopic observations. The original description has not been inspected for this account. [colfungi-370729-2026] [ramirez-cruz-2013-types]

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.

    • 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.

Claim provenance

Source checks record what was inspected. Publication approval and section review are separate editorial decisions.

The name and nomenclatural citation agree between the inspected database record and the type revision.

Fields: taxonomy.canonical_name, taxonomy.accepted_name, taxonomy.genus, taxonomy.specific_epithet, taxonomy.authority, taxonomy.publication_year

Retain the species following the inspected type treatment, corroborated by current database acceptance; this is a scoped editorial decision, not a genus-wide reconciliation.

Fields: taxonomy.status

Adopt Agrocybaceae following the 2026 phylogenomic family treatment, which explicitly includes Psilocybe.

Fields: taxonomy.family

The Colombian Fungi database places the species in Hymenogastraceae.

This Colombian account centres on the 2013 re-examination of type material. It documents selected microscopic features and the collection provenance, while chemical evidence and broader ecology remain unresearched.

Fields: overview.text

The examined material has reported spores of 5.6–7.2(8.0) × 4.0–4.8 × 3.2–4.4 µm. The revision records pileocystidia embedded in the ixocutis, a ramose subhymenium and setaceous hyphae in the basal mycelium. These are selected observations from the specimen labelled an isotype in the paper.

Fields: description.microscopic.text

The revision lists G. Guzmán 35331 (XAL, isotype), collected on 24 September 2002 at Pacurita, southeast of Quibdó in Chocó, Colombia. This locality is specimen provenance; it does not delimit the species’ range.

Fields: distribution.narrative.text

The name is attributed to Guzmán, M. Torres and Ramírez-Guillén, published in International Journal of Medicinal Mushrooms 6(1):86 (2004). The 2013 type revision adds microscopic observations. The original description has not been inspected for this account.

Fields: history.text

The cited GBIF download contains no georeferenced records for this name. This is an absence of records rather than evidence of absence, and no range has been researched for this account.

Fields: distribution.occurrence

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. No active iNaturalist species taxon was located for this name, so that identifier is left empty.

Fields: distribution.gbif_taxon_id

Country of the type material as recorded in the type study. No range statement was located, so the known range is left unresearched.

Fields: distribution.countries

Conflicting evidence

Resolved: taxonomy.family

The database uses an older family placement than the 2026 phylogenomic treatment.

Follow Niskanen et al. (2026), which explicitly includes Psilocybe in Agrocybaceae. The database supports the name and acceptance, not the family adopted here. — Psilocybia editorial, 2026-09-12
