Data sources and licences

Observations from GBIF.org (human observations and herbarium specimens; records flagged with geospatial issues excluded) and iNaturalist research-grade records, retrieved 2 November 2026.

Map: © OpenStreetMap contributors. Province centres: Wikidata. Region comes from the record's GADM province, or the nearest province centre when missing. For protected species (iNaturalist "threatened" or IUCN VU/EN/CR) locations are rounded to ~10 km; locations obscured by iNaturalist are marked "approximate".

An observation shows that a mushroom was seen there on that day, not that it is there now or that it may be picked. Counts reflect how many people record fungi in an area more than how common a species is.
