Ethnomycology is the study of the bio-cultural aspects of human-fungal interactions. This article discusses the involvement of the bracket fungus Fomitopsis betulina within the material culture of traditional games. With a particular focus on the Nordic countries, the aim is to review and analyze the use of simple balls made of bracket fungi. We argue that the fungi ball can be considered the precursor of the rubber (and the gutta-percha) ball. Moreover, the replacement of fungi balls with rubber balls marks, to a certain extent, a temporal transition from traditional folk games with roots in pre-industrial society to modern sports in which balls and other equipment received a more standardized shape.

北欧海盗游戏和Sámi消遣：制作白桦Fomitopsis betulina的球

人类学是对人与真菌相互作用的生物文化方面的研究。本文讨论了传统真菌的材料文化中支架真菌白粉病的参与。特别关注北欧国家，目的是审查和分析由支架真菌制成的简单球的使用。我们认为真菌球可以被认为是橡胶（和古塔胶）球的前身。此外，用橡胶球代替真菌球在一定程度上标志着从植根于前工业社会的传统民间游戏到现代运动的短暂过渡，在现代运动中，球和其他设备的形状更加标准化。
