Notes – Synnemasporella accommodates two species, S. aculeans and S. toxicodendri (Fan et al. 2018). Cryptodiaporthe aculeans, which has perithecial ascomata as well as sporodochial and/or pycnidial conidiomata (Fan et al. 2018), was transferred to Synnemasporella. Cryptodiaporthe aculeans was introduced by Wehmeyer (1933b) who noted that Cryptodiaporthe contained a heterogeneous group of species which would probably be separated into several genera when their relationships were fully understood. Initially, Cryptodiaporthe was considered a synonym of Plagiostoma (Sogonov et al. 2008, Mejía et al. 2011, Voglmayr et al. 2017). However, phylogenetic analyses (Senanayake et al. 2017a) indicated that they are two separate genera. Synnemasporella toxicodendri differs from Cryptodiaporthe aculeans in having longer synnemata, a flat to slightly concave conidiogenous cell on the top of the synnemata and smaller conidia. Synnemasporella toxicodendri is illustrated for this entry.
