| description | Background and Aims: The briofilous fungi are a diverse and polyphyletic group of symbiotic mushrooms associated specifically with few bryophyte species, genera or families. Paruephaedria heimerlii stands out as a species with a bryophilous habit in Jungermanniales; it is known from Alaska, Europe, Japan and Tasmania. Therefore, the objective of this work is to present the first record of this species in Mexico, its first known tropical locality.Methods: The studied specimens were collected in the vegetation of pine-oak forest and tropical cloud forest in the state of Veracruz, Mexico. The material was herborized and decontaminated by cooling, followed by determination from histological sections of the ascomas and observed with an optical microscope. Finally, the material was deposited in the fungal collections of the herbaria ENCB of the Instituto Politécnico Nacional and XALU of the Facultad de Biología of the Universidad Veracruzana.Key results: Using morphological characteristics and measures of sexual structures like spores, asci and hymenial structures, the studied material was determined as Paruephaedria heimerlii, representing the first record of this species both in Mexico and for the tropics. Conclusions: According to our observations and comparisons with reports in literature, it is probable that the presence of P. heimerlii is not conditioned to the temperature or altitude of the habitat in which it is found, but to the availability of hosts. |

Antecedentes y Objetivos: Los hongos briófilos son un grupo diverso y polifilético de hongos simbióticos asociados específicamente con algunas especies, géneros o familias de briofitos. Paruephaedria heimerlii destaca como una especie con hábito briófilo en Jungermanniales; se conoce de Alaska, Europa, Japón y Tasmania. Es por ello que el objetivo de este trabajo es presentar el primer registro de la especie para México, siendo esta la primera localidad tropical.Métodos: Los ejemplares estudiados fueron colectados en la vegetación de bosque de pino-encino y en bosque de niebla en el estado de Veracruz, México. El material fue herborizado y descontaminado por enfriamiento, posteriormente determinado a partir de cortes histológicos de los ascomas y observado bajo el microscopio óptico. Finalmente, los ejemplares fueron depositados en la colección de hongos de los herbarios ENCB del Instituto Politécnico Nacional y XALU de la Facultad de Biología de la Universidad Veracruzana. Resultados clave: Usando características morfológicas y mediciones de estructuras sexuales como esporas, ascas y estructuras himeniales, el material estudiado se determinó como Paruephaedria heimerlii, lo cual representa el primer registro de esta especie tanto para México como para el trópico.Conclusiones: De acuerdo con nuestras observaciones y comparaciones con lo reportado en la literatura, es probable que la presencia de P. heimerlii no esté condicionada a la temperatura o altitud del hábitat en el cual se encuentra, pero sí a la disponibilidad de hospederos.
