Graphostromataceae

The Graphostromataceae are a family of fungi in the order Xylariales. This was a monotypic family, containing the single genus Graphostroma, which in turn contains the single species Graphostroma platystoma.
Species Fungorum added genus Theissenia to the family.
In 2018, multi-gene phylogenetic analyses revealed that Graphostromataceae was close to the families of Barrmaeliaceae and Xylariaceae.
Then based on phylogeny and morphology, Theissenia was excluded from the family and accepted in Hypoxylaceae.
Five accepted genera maybe contained in the Graphostromataceae family; Biscogniauxia, Camillea, Graphostroma, Obolarina, and Vivantia. Species Fungorum agrees on the above.
