Cyttaria espinosae

Cyttaria espinosae (Lloyd), also known by its local name digüeñe, dihueñe, lihueñe, quireñe, pinatra, or quideñe, is an orange-white coloured and edible ascomycete fungus native to south-central Chile and Argentinean Patagonia. The digüeñe is a strict and specific parasite of Nothofagus, mainly Nothofagus obliqua trees and cause canker-like galls on branches from which the fruiting bodies emerge between spring and early summer. The pitted surface generates air turbulence, preventing a build-up of static air around the fruitbodies, thus facilitating wind-borne spore dispersal.
