2.5.9 Monosporascus cannonballus ( Figure 4 )

Pollack and Uecker (1974) introduced this species from the roots of Cucumis melo ( Cucurbitaceae ) in Arizona. It causes root rot and vine decline ( MRVD) of muskmelon in Greece ( Markakis et al. 2018), and is reported as ubiquitous as a root endophyte ( Robinson et al. 2020). The genomes of Monosporascus species were assembled by Robinson et al. (2020). The species was recorded for the first time from the marine environment by Jin and Huang (2009) from incubated drift and intertidal woods collected from the coasts of Yellow Sea and Bohai Sea ( China). It groups in the Diatrypaceae ( Xylariales , Xylariomycetidae, Sordariomcyetes) ( Maharachchikumbura et al. 2015).
