Poisonous look-alikes of the poplar mushroom

Records by region: Marmara 15; Central Anatolia 4; Eastern and Southeastern Anatolia 3; Aegean 1. Most records come from İstanbul, Ankara, Diyarbakır, İzmir and Kocaeli.

Records peak in March, May and October; about 60% of dated records fall in September–November and 30% in March–May.

In Turkey, poplar mushroom records fall in spring (March–May) and autumn (September–December); 11 of the 23 observations on our map are from October. In cultivation it is grown all year.

The poplar mushroom grows in clusters on stumps, in trunk hollows and on the roots of poplars, willows and other broadleaved trees; it breaks down dead wood as a white rot and also appears on old or wounded living trees.

Funeral bell (Galerina marginata, deadly): Also grows in clusters on wood, brown with a ring; but smaller (cap 1–6 cm), with a thin brown stem and rusty-brown spore print. Contains amatoxins that destroy the liver.

Sulphur tuft (Hypholoma fasciculare, poisonous): Forms crowded clusters on stumps; sulphur-yellow cap, greenish-yellow gills turning purple-brown; no ring and a very bitter taste. Poisonous (First Nature).

Oyster mushroom (Pleurotus ostreatus, edible): Also called kavak mantarı in Turkey; but fan-shaped, stemless or with a short side stem, without a ring, and its gills run down the stem.

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.
