[2] Phylogenetic research has shown that while it belongs to P. djamor-cornucopiae clade, it forms its own intersterility group.

[3] The 2.5-10 cm large fruiting bodies of Pleurotus calyptratus are semicircular, shell-shaped to kidney-shaped.

The pileus surface is smooth, wrinkled with age, bald and at least a bit greasy in damp weather.

The white, later yellowing, skin-like veil that stretches from the cap edges over the lamellae in young fruiting bodies is striking.

In Central Europe there are reports of finds from Germany, Croatia,[7] Poland,[8] Liechtenstein, Austria, Slovakia, Czech Republic and Hungary.

It was able to benefit little from the spread of the trembling poplar, planted by humans as soil-preparing forest pioneers after World War II.

[2] Pleurotus calyptratus is an edible mushroom,[9] as a tree and wood parasite it is insignificant due to its rarity.
