The genus Sphaerodes was founded by Clements to accommodate S. episphaeria in 1909. It was distinguished from Sphaeroderma by the lack of a subiculum. Because of Clements＇ incorrect differentiation of S. episphaeria and Neocosmospora, the genus was not used by later authors. Clements ＆ Shear （1931） incorrectly suppressed the name in favor of Vittadinula （Sacc.） Clem. ＆ Shear, which Saccardo （1883） had treated as a subgenus of Sphaeroderma with the same diagnostic feature as Sphaerodes. Some authors integrated the genus with Sphaeroderma （e. g. Petch, 1938）, Melanospora （e.g. Doguet, 1955） or Microthecium （e. g. Hawksworth ＆ Udagawa, 1977）, while von Arx （1981） emphasized it for Melanospora-like fungi with reticulations on the ascospores. Cannon ＆ Hawksworth （1982） re-evaluated Melanospora, Sphaerodes and similar pyrenomyecetes of the family Ceratostomataceae （Hypocreales） and clarified their differentiation.
