Guayaquilia gen. nov., typified by Idriella cubensis

Abstract:

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.
