Records by region: Marmara 19; Black Sea 10. Most records come from İstanbul, Kırklareli, Düzce, Bolu, Zonguldak, Kastamonu, Sinop and Samsun.

The porcelain fungus appears from late summer to late autumn. Our Turkish records fall in June, September, October and November, the great majority in October.
Almost exclusively on beech: dead or fallen trunks, cut branches and sometimes high dead branches of living trees; rarely on oak. It grows in clusters on wood, never from soil.
Destroying angel (Amanita virosa, deadly): The destroying angel is also white and ringed, but it grows from soil, has a sac-like volva at the stem base and its cap is not slimy and translucent. The porcelain fungus grows only on wood, in clusters.
Oyster mushroom (Pleurotus ostreatus, edible): The oyster mushroom also grows in clusters on wood, but its stem is short and off-centre or absent, it has no ring and its cap is not slimy.
Rooting shank (Hymenopellis radicata, inedible): A close relative, but it grows singly, has a brownish wrinkled cap, no ring, and a long root-like stem extending down to buried wood.

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.
