New species of Hughesinia and Stachybotryna and new records of anamorphic fungi from the Yucatan Peninsula, Mexico

During an investigation of anamorphic fungi on tropical plant debris from the Yucatan Peninsula, Mexico, two new species in the genera Hughesinia and Stachybotryna were described. Additionally, 15 other anamorphic fungi were determined; five of them are newly recorded for Mexico. Hughesinia heterospora sp. nov. is characterized by conidiophores macronematous light brown, conidiogenous cells monotretic and dark brown, muriform conidia which differ from other species of Hughesinia in having great morphological heterogeneity. Stachybotryna variegata sp. nov. is characterized by conidiophores macronematous light brown, variegated setae, brown below and hyaline towards the apex, conidiogenous cells monophialidic and ellipsoidal to broadly fusiform, guttulate, hyaline conidia. Descriptions, illustrations and keys are provided.
