Type genusCalcarisporium Preuss

Notes – Multi-gene analysis revealed that Calcarisporium species form a monophyletic lineage which is distinct from other families in Hypocreales. This family is distinguished from other families by its verticillate conidiophores with a narrow apical part and monoblastic to polyblastic, sympodial and denticulate conidiogenous cells at the apex (Sun et al. 2017). Calcarisporium arbuscula is illustrated in the entry.
