It is typically pale gray shading to darker gray in the center (though some

Sporocadus is a genus of plant pathogens in the family Sporocadaceae. Species of the family Sporocadaceae are endophytic, plant pathogenic or saprobic, and associated with a wide range of host plants. Sporocadus was established by Corda (in 1839) to include four species, but with no mention of the type. Hughes (in 1958) tried to lectotypify Sporocadus based on Sporocadus lichenicola. The genus was once synonymised under Seimatosporium by Sutton (in 1975), but was later classified as a distinct genus by Brockman (in 1976) and Nag Raj (in 1993). Liu et al. (2019a) showed that both Sporocadus
