The green-cracking brittlegill fruits from early summer into autumn; Turkish GBIF records fall between June and October.
The green-cracking brittlegill grows in broadleaf woods, especially under oak and beech, forming a mycorrhizal partnership with the trees.
Death cap (Amanita phalloides, deadly): Its cap is smooth, shiny olive-green and never cracks; it has a ring and a sack-like volva, and the fibrous stem does not snap like chalk. It is deadly.
Grass-green brittlegill (Russula aeruginea, edible): Smooth, grass-green cap that does not crack into patches; usually under birch.
Charcoal burner (Russula cyanoxantha, edible): Cap in mixed purple, blue and green; its gills are flexible rather than brittle.

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.
