Psilocybe subtropicalis

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

Scoped account prepared by Codex; no human scientific review. 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

Agent source-checked

A comparison of Mexican and Costa Rican type material underlies this account. It follows the published synonymy of P. bipleurocystidiata with P. subtropicalis and keeps the two type collections distinct. [ramirez-cruz-2013-types]

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

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

Agent source-checked

The subtropicalis holotype has reported spores of 6.4–8.0 × 5.6–6.4(7.2) × 4.4–4.8 µm, subhexagonal or subrhomboid in frontal view and ellipsoid laterally. The revision distinguishes leptocystidia arising from the subhymenium and deuterocystidia arising from the hymenophoral trama. Pileocystidia were absent in this holotype but observed in the bipleurocystidiata isotype. These are observations of the examined material, not a complete description of species variation. [ramirez-cruz-2013-types]

04Distribution and ecology

Agent source-checked

The revision examined the Mexican holotype L. Montoya 910 (XAL), collected on 6 October 1986 at the Francisco Javier Clavijero Ecological Park near Xalapa, Veracruz. It also examined R. Singer 14484 (XAL, bipleurocystidiata isotype), collected on 25 July 1986 at Monte Verde Cloud Forest Reserve, Costa Rica. These are collection localities within the adopted treatment, not a complete distribution map. [ramirez-cruz-2013-types]

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

Agent source-checked

The type revision cites the original subtropicalis description in Bibliotheca Mycologica 159:107 (1995) and the bipleurocystidiata description in Sydowia 61(2):216 (2009). Its 2013 reassessment unites them. The original descriptions have not been inspected for this account. [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.

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.

A separately described name was synonymized after comparison of type material.

Follow the 2013 type-based synonymy, corroborated by the current Catalogue of Life record. Preserve differences reported between the examined types; do not infer identical morphology in every collection. — Codex (agent), 2026-09-12
