Amphisphaeriales is an order of fungi within the class Ascomycetes. These fungi are primarily characterized by their unique fruiting bodies, which are often small and can be found on decaying wood or plant material. They play a significant role in the decomposition process, contributing to nutrient cycling in ecosystems. Members of Amphisphaeriales are typically saprophytic, meaning they feed on dead organic matter. They reproduce through the formation of ascospores, which are contained within specialized structures called asci. This order includes various genera, some of which are important for studying fungal biodiversity and ecology.
