Records by region: Aegean 7; Marmara 6; Central Anatolia 1; Mediterranean 1; Black Sea 1. Most records come from İzmir, Manisa, İstanbul, Karaman, Muğla, Yalova, Kırklareli and Balıkesir.
Records peak in January, October and December; about 56% of dated records fall in September–November and 0% in March–May.
The jack-o'-lantern mushroom fruits in autumn and early winter; Turkish GBIF records run from October to January.
It grows in clusters on stumps, roots and trunk bases of broadleaf trees such as olive, oak and chestnut, and is common in Mediterranean climates.
Chanterelle (Cantharellus cibarius, edible): The chanterelle grows singly from soil, not in clusters on wood; under the cap it has thick, forked, blunt ridges rather than true gills. It is egg-yolk yellow with whitish flesh and a faint apricot smell.
False chanterelle (Hygrophoropsis aurantiaca, inedible): It is smaller, with crowded, forked orange gills, and usually grows on soil or rotting wood in conifer forests.
Chicken of the woods (Laetiporus sulphureus, edible): Chicken of the woods is also orange but forms tiers of pored brackets without gills. The jack-o'-lantern has true gills and grows in clusters.

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.
