Type speciesSaprothyrium thailandense (Senan., Tangthir. & K.D. Hyde) U. Braun, Crous & J.Z. Groenew

Notes – Pycnothyria of Saprothyrium differ in having a scutellum with obtuse outer strands with globose to subglobose hyaline conidia, and is similar with Sphaerosporithyrium. However, it clusters in a phylogenetically distant clade to clades of Tubakia sensu stricto (Braun et al. 2018). Saprothyrium can be distinguished from all other species of Tubakia sensu stricto by hyaline, globose to subglobose conidia formed in pycnothyria (Braun et al. 2018). Saprothyrium thailandense is illustrated in this entry.
