Based on phylogenies of LSU analyses and morphological studies, Chaetothyriothecium, a “Microthyriaceae”-like fungus collected in central Thailand was established by Hongsanan et al. (2014) to accommodate the type species Chaetothyriothecium elegans. Chaetothyriothecium is characterized by superficial, globose, dark brown to black ascomata, ostioles surrounded by long setae, bitunicate asci, 4−8-spored, and bi-celled hyaline ascospores with oblong to ellipsoid (Hongsanan et al. 2014). Chaetothyriothecium can be recognized by the presence of long, dark brown setae at the center surrounding the ostiole (Hongsanan et al. 2014). No other species have been introduced to this genus, which remains monotypic.
Type species: Chaetothyriothecium elegans Hongsanan & K.D. Hyde
Other accepted species: This genus is monotypic.
