Amphisphaeriaceae

The Amphisphaeriaceae is a family of fungi that belongs to the class Sordariomycetes. The family was first described by the Swedish botanist Elias Magnus Fries in 1825 and subsequently revised by various mycologists. The Amphisphaeriaceae comprise approximately 45 genera, many of which are still awaiting formal classification.

Species within this family are typically characterized by their ascomata, which are typically immersed in the substrate or epidermal tissue of the host plant. The asci are often unitunicate and variably shaped, typically with 1-8 spores per ascus. The spores are usually hyaline, rod-shaped, and one- or multi-septate.

Studies have revealed that members of Amphisphaeriaceae are saprotrophic to facultatively parasitic, with some species exhibiting a necrotrophic lifestyle. They are often associated with plant tissues, where they produce appressoria and haustoria to facilitate feeding. In some cases, they form a symbiotic relationship with their hosts, contributing to nutrient cycles and ecosystem dynamics.

Amphisphaeriaceae species have been identified across a wide range of habitats, from tropical rainforests to temperate soils. Notable genera within this family include Monochaetia, Sporidesmium, and Mycosphaerella. More research is needed to elucidate the taxonomic relationships among members of the Amphisphaeriaceae, as well as their ecological roles and potential applications.

Phylogenetic analyses have shown that the Amphisphaeriaceae are closely related to other families within the Sordariomycetidae clade. Further studies using molecular data and morphological characteristics are necessary to fully understand the interrelationships and evolutionary history of this family.
