Suillellus adonis

Suillellus adonis is a species of bolete fungus described from Croatia in 2002 and named after the Greek mythological figure Adonis for its striking beauty and vibrant red colouration. The mushroom produces fruiting bodies with deep red caps that fade to reddish-orange or yellow-orange at the margins, yellow pores that turn intensely blue when bruised, and stipes with yellow to golden colours with a dark wine-red base and powdery surface. Its flesh quickly turns blue when cut, and it has a distinctive microscopic characteristic of staining deep turquoise to blackish blue with Melzer's reagent. This apparently rare fungus has been found in Mediterranean regions of Croatia, Italy, and Cyprus, where it grows in groups near holm oak and European black pine, suggesting it forms mycorrhizal relationships with these trees.
