Notes – Sutton (1980) and Wijayawardene et al. (2014a, 2016a) treated the genus as an appendage bearing coelomycetous fungus, although Nag Raj (1993) did not mention the gelatinous sheath. Crous et al. (2015a) also observed the gelatinous sheath of M. desmazieri. 

Macrodiplodiopsis desmazieri (as Hendersonia desmazieri Mont.), has been regarded as the asexual morph of Massaria platani (current name: Splanchnonema platani by Shear & Davidson (1936) but Glawe (1985) rejected this link. However, Crous et al. (2015a) described the sexual morph of M. desmazieri. Wijayawardene et al. (2014a) erroneously reduced Misturatosphaeria and Floricola under Macrodiplodiopsis but Crous et al. (2015a) reinstated the genera.
