Spirographa
Introduction '''''Spirographa''''' is a genus of parasitic fungi. It is the sole genus in the monotypic family '''Spirographaceae''', belong to the order Ostropales. The genus was circumscribed by Alexander Zahlbruckner in 1903, with ''Spirographa spiralis'' later assigned as the type species in 1923.The family Spirographaceae was circumscribed by Adam Flakus, Javier Etayo and Jolanta Miadlikowska in 2019 on the basis of molecular phylogenetic analysis. They determined that genus ''Spirographa'' is an independent lineage in the Ostropales, sister to the clade containing the families Fissurinaceae, Gomphillaceae, and Graphidaceae.
