koningsboleet

Compound of koning (“king”) +‎ -s- +‎ boleet (“bolete”).

• IPA^(key): /ˈkoː.nɪŋsˌboː.leːt/

koningsboleet m (plural koningsboleten, diminutive koningsboleetje n)

1. royal bolete (Butyriboletus regius syn. Boletus regius)

   Hypernym: boleet

2. (informal, misnomer) synonym of kruisdisteloesterzwam (“king trumpet mushroom”)

• The sense "king trumpet mushroom" (i.e. Pleurotus eryngii) is a misnomer, as that mushroom is not a bolete proper.
