A new genus Guayaquilia is established to accommodate Idriella cubensis based on morphology and phylogenetic analysis. DNA sequence data place these specimens as incertae sedis separate from Microdochiaceae ( Xylariales ), forming a monophyletic lineage separated from Neoidriella desertorum and phylogenetically distant from Idriella . The novel genus is characterized by macronematous, tree-like, fasciculate, profuse dichotomously, alternately, or irregularly branched, brown conidiophores with polyblastic, denticulate, sympodial extended, intercalary and terminal conidiogenous cells that produce solitary, sublunate, subnavicular, lunate, inequilateral, (0–)1-septate, hyaline conidia.
