Type species –Chromolaenomyces appendiculatusMapook & K.D. Hyde, Fungal Divers 101: 96 (2020).

Notes –Chromolaenomyceswas introduced to accommodateChromolaenomyces appendiculatusas a saprobe on dead stems ofChromolaena odorataby 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 fromThyridariellawhich has clavate asci with moderately long pedicel and muriform ascospores, however,Chromolaenomycesspecies have cylindrical asci with a short pedicel and aseptate ascospores (Devadatha et al. 2018b, Mapook et al. 2020). Phylogenetically,Chromolaenomyces appendiculatusforms a distinct clade and a sister relationship withThyridariella mangrovei(Mapook et al. 2020). Therefore,Chromolaenomyceswas introduced with one species based on multi-gene analyses with LSU, ITS, rpb-2, SSU and tef1 sequence data and its morphological distinctness.
