| description | Background and Aims: Asexual micromycetes (AM) are a diverse and abundant group of fungi in nature. Until now the AM had not been studied in the natural areas of Mexico State. The aim of this contribution is to provide information on the AM species richness on senescent living leaves and decomposing leaves on the ground of five species of Quercus from a temperate forest in the municipality of Huixquilucan in Mexico State, Mexico.Methods: During one year, every two weeks, samples of mature living leaves were cut from five oak species, and dead leaves were collected from the ground. Samples were incubated in moist chambers. Microscopic examination was carried out twice a week. Taxonomic determinations were based on conidiogenesis and on morphometric characters of the conidiomata. Reference material (microscopic slides) was deposited in the herbarium of the Instituto de Ecología, A.C. (XAL) in Xalapa, Veracruz, Mexico. The new records for the mycobiota from Mexico are illustrated and described in detail.Key results: Thirty AM species were determined; 12 were not known from Mexico, and all of them are new records for Mexico State. More species were found on the decaying leaves on the ground than on senescent living ones. Eight species of AM had not been collected since they were described as new species for science. Trichothecium roseum, Pestalotiopsis maculans and Vermiculariopsiella immersa are widely distributed micromycetes on the leaves of all the studied oaks.Conclusions: The richness of AM species found in the study area shows that Quercus leaves are substrates that harbor a considerable fungal richness, largely unknown in Mexico. This is an important reason for the conservation of Quercus forests and promoting studies on AM in our country. |

Antecedentes y Objetivos: Los micromicetos asexuales (MA) constituyen un grupo diverso y abundante de hongos en la naturaleza. Hasta la fecha, para el Estado de México no se habían realizado estudios sobre estos hongos. El objetivo de esta aportación es proporcionar información sobre la riqueza taxonómica de las especies de MA que habitan en hojas vivas senescentes y muertas de cinco especies de Quercus de un bosque templado en el municipio Huixquilucan, Estado de México, México.Métodos: Durante un año, quincenalmente se cortaron hojas de cinco especies diferentes de encinos vivas senescentes y se recolectaron hojas del suelo. Las muestras se incubaron en cámaras húmedas; la revisión microscópica se efectuó dos veces por semana. La determinación taxonómica se basó en la conidiogénesis y en las características morfométricas de los conidiomas. El material de referencia (preparaciones microscópicas), se depositó en el herbario del Instituto de Ecología, A.C. (XAL) en Xalapa, Veracruz, México. Los nuevos registros para la micobiota de México se ilustran y describen en detalle.Resultados clave: Se identificaron 30 especies de MA, 12 de ellas constituyen nuevos registros para el país y todas lo son para el Estado de México. En las hojas muertas del suelo hubo un mayor número de especies que en las hojas vivas senescentes. Ocho de los taxones identificados no habían sido recolectados desde que fueron descritos como especies nuevas para la ciencia. Trichothecium roseum, Pestalotiopsis maculans y Vermiculariopsiella immersa son micromicetos que están ampliamente distribuidos en las hojas de todas las especies de encinos estudiadas.Conclusiones: La riqueza de MA encontrada en el área de estudio evidencia que las hojas de los Quercus son sustratos que albergan una considerable riqueza fúngica aun desconocida en México. Lo anterior es una importante razón para la conservación de los bosques de Quercus y promover estudios sobre este grupo de micromicetos en nuestro país.
