Description Background and Aims: The genus Unguiculariopsis of the class Leotimycetes within Ascomycota is characterized by forming inconspicuous apothecia up to 2 mm in diameter, with hook-shaped hairs on the external surface, inoperculate and inamyloid asci, and globose, subglobose to ellipsoid ascospores, which are hyaline with guttules. They are fungicolous fungi which are host-specific. The objective of this study is to report Unguiculariopsis ravenelii for the first time in Mexico.Methods: The specimens studied are deposited in the ENCB herbarium of the Instituto Politécnico Nacional, Mexico. The material was reviewed in fresh and dry, and described macromorphologically using a stereomicroscope, based on pictures taken in situ, and micromorphological characters with an optical microscope. They were identified with specialized keys and literature.Key results: The description of Unguiculariopsis ravenelii of Mexico is presented. This is a species characterized by being mycoparasite and forming gregarious apothecia growing on Rhytidhysteron rufulum.Conclusions: This species is distributed in tropical dry forest and produces its sporomas during the rainy season in the states of Colima, Jalisco, Nayarit, Oaxaca, Puebla, Sonora, Tabasco and Tamaulipas in the Neotropical region of Mexico.
Antecedentes y Objetivos: El género Unguiculariopsis de la clase Leotiomycetes dentro de Ascomycota se caracteriza por formar apotecios inconspicuos de hasta 2 mm de diámetro, con una superficie formada por pelos en forma de gancho, ascas inoperculadas, inamiloides y ascosporas globosas, subglobosas a elipsoidales, hialinas con gútulas. Son hongos fungícolas que presentan especificidad por el hospedero; en el presente estudio se tiene por objetivo reportar a Unguiculariopsis ravenelii por primera vez en México.Métodos: Los especímenes estudiados están depositados en el herbario ENCB del Instituto Politécnico Nacional, México. Los materiales fueron revisados en fresco y en seco, se describieron macro morfológicamente usando un estereoscopio, fotografías tomadas in situ y micro morfológicamente con un microscopio óptico. Se identificaron con claves y literatura especializada.Resultados clave: Se presenta la descripción de Unguiculariopsis ravenelii de México, una especie que se caracteriza por ser micoparásita y por formar apotecios gregarios sobre Rhytidhysteron rufulum. Conclusiones: Esta especie se distribuye en bosque tropical caducifolio y produce sus esporomas durante la temporada de lluvias en los estados de Colima, Jalisco, Nayarit, Oaxaca, Puebla, Sonora, Tabasco y Tamaulipas en la región Neotropical de México.
