Type genus – Ageratinicola Lu L., K.D. Hyde & Tibpromma
Notes – Ageratinicolaceae is introduced to accommodate Foliophoma and Ageratinicola gen. nov. In the phylogenetic analyses, Ageratinicolaceae formed an independent branch between Libertasomycetaceae and Coniothyriaceae. Ageratinicolaceae can be distinguished from Coniothyriaceae and Libertasomycetaceae by their muriform, non-constricted conidia at the septa. However, conidia of Coniothyriaceae are phoma-like, camarosporium-like, coniothyrium-like, or cladosporium-like, and Libertasomycetaceae has conidia which constricted at the median septum with longitudinal striations (Crous and Groenewald 2017; Wijesinghe et al. 2023).
