Psilocybe wayanadensis

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

Scoped agent source check; no human scientific review. Chemistry, molecular literature, conservation, scientific imagery and occurrence datasets remain unresearched. Comprehensive synonymy and literature coverage remain incomplete. Original description, macroscopic characters and ecology remain unchecked. Original spore dimensions are reported only through the revision.

01Overview

Agent source-checked

This scoped account documents selected type-based observations and collection provenance. The literature review remains incomplete, and differing morphological observations are attributed to their sources. [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

Not yet researched

This section has not yet been researched for this account.

Microscopic characters

Agent source-checked

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

Agent source-checked

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

Not yet researched

Habitat and substrate literature has not yet been checked for this account. The type locality alone does not establish ecological preferences.

Occurrence records

No occurrence points loaded.

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

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 compound presence or absence.

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

07History

Agent source-checked

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.
