Grandigallia dictyospora M.E. Barr et al., Mycotaxon 29: 196 (1987)

The monotypic genus Grandigallia was introduced by Barr (1987) and is typified by G. dictyospora. The fungus infects branches of Polylepis sericea Wedd. (Rosaceae) and produces conspicuous (3–14 cm in diam.) and black ascostromata. Grandigallia closely resembles Shiraia in having muriform ascospores, however, it differs by its black and larger ascostromata. Kirk et al. (2008) and Lumbsch and Huhndorf (2010) placed Grandigallia in Dothideomycetes, genera incertae sedis.Ariyawansa et al. (2013) re-examined the type material and transferred it to Shiraiaceae in Pleosporales. Wijayawardene et al. (2014, 2017, 2018) accepted this placement.
