Cyttaria are a genus of parasitic hose fungi (Ascomycota), which form their own family Cyttariaceae and order Cyttariales .
The genus contains around a dozen species, all of which live parasitically on Nothofagus , i.e. are restricted to the southern hemisphere.
The fruiting bodies are large, fleshy round to pear-shaped structures that grow from galls on living branches of the host tree. In some species the fruiting bodies form pycnidia in an early stage , and later several separate, bowl-shaped chambers with the asci . The asci have a thin cell wall and an apical amyloid ring.
Systematics
Cyttaria used to be in different groups, such as the Becherling or the Helotiales . Phylogenetic studies have placed them clearly in the class Leotiomycetes , but they are within the Helotiales. The latter, however, are not monophyletic, which is why Cyttaria continues to be listed as a separate order. Its closest relative is likely to be the genus Chlorociboria , an Australasian genus that lives in deadwood.
