Psilocybe magnispora

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

Scoped agent source check; no human scientific review. Original descriptions, comprehensive morphology and synonymy remain incomplete. Macroscopic descriptions, chemistry, molecular literature, conservation, scientific imagery and occurrence datasets remain unresearched. Collection localities do not establish a complete range.

01Overview

Agent source-checked

This is a scoped account based on re-examined type material. Selected microscopic observations and collection context are documented; broader literature coverage remains incomplete. [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 revision reports spores 6.4–8.0 × 5.2–6.4(7.2) × 4.8–5.6 µm and gill-edge cystidia embedded in a gelatinized layer. These observations concern the examined isotype. [ramirez-cruz-2013-types]

04Distribution and ecology

Agent source-checked

E. Horak 10171 (XAL, isotype) was collected on 10 July 2002 at Pong Chang, Princess Trail, Thailand; the revision spells the park name “Kha Yai”. This is specimen provenance, not a range boundary. [ramirez-cruz-2013-types]

Ecological context

Agent source-checked

The examined collection came from tropical montane broadleaf forest. Broader habitat and substrate coverage remains pending. [ramirez-cruz-2013-types]

No occurrence points loaded.

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

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.

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.
