Quick Summary

The Septobasidiales are an order of fungi within the phylum Basidiomycota. These fungi are primarily parasitic on plants, with some species also exhibiting parasitic or symbiotic relationships with scale insects. A notable characteristic of this order is that their basidiospores germinate on insects, and haustoria (specialized hyphae) coil inside the insect. The genus Septobasidium is the type genus for this order and is characterized by smooth shelf fungi that typically have a well-developed hypobasidium.12
