Type speciesChromolaenomyces appendiculatus Mapook & K.D. Hyde, Fungal Divers 101: 96 (2020).

NotesChromolaenomyces was introduced to accommodate Chromolaenomyces appendiculatus as a saprobe on dead stems of Chromolaena odorata by Mapook et al. (2020). It is characterized by coriaceous, globose to subglobose, light brown to brown cylindrical ascomata with a protruding ostiole, cylindrical asci with a short pedicel and 1-seriate, irregular arrangement, oval to broadly fusiform, aseptate ascospores with a narrow sheath, drawn out to form polar appendages from both ends. These characters differentiate it from Thyridariella which has clavate asci with moderately long pedicel and muriform ascospores, however, Chromolaenomyces species have cylindrical asci with a short pedicel and aseptate ascospores (Devadatha et al. 2018b, Mapook et al. 2020). Phylogenetically, Chromolaenomyces appendiculatus forms a distinct clade and a sister relationship with Thyridariella mangrovei (Mapook et al. 2020). Therefore, Chromolaenomyces was introduced with one species based on multi-gene analyses with LSU, ITS, rpb-2, SSU and tef1 sequence data and its morphological distinctness.
