          Abstract

          La micofagia por roedores en hongos hipogeos ha sido documentada en diversos ecosistemas del mundo; sin embargo, el estudio del consumo de hongos epigeos por este grupo ha sido insuficiente. En el presente trabajo se evaluó de manera experimental la micofagia de 2 especies de ratones silvestres (Neotomodon alstoni y Peromyscus maniculatus) en el hongo epigeo ectomicorrizógeno Russula aff. cuprea y la posible preferencia de estos ratones por consumir alguna estructura específica del hongo (píleo, himenio o estípite). Asimismo, se analizó si el paso del hongo a través del tracto digestivo afectaba la actividad metabólica esporal. Los resultados indican que aunque el esporoma entero puede ser consumido, el himenio (parte fértil) es la primera estructura seleccionada por ambas especies. Además, se encontró que el paso por el tracto digestivo de las 2 especies de ratones no tiene efecto significativo (p= 0.067) en la actividad metabólica esporal de R. aff. cuprea, sugiriendo que estos ratones silvestres podrían ser dispersores efectivos de las esporas del hongo epigeo en el Parque Nacional La Malinche.

          Translated abstract

          The mycophagy by rodents in hypogeous fungal species has been widely documented in different ecosystems around the world. However, the consumption of epigeos fungi by this group has been poorly studied. In this study we evaluated the mycophagy by 2 mice species (Neotomodon alstoni and Peromyscus maniculatus) in the epigeous ectomycorrhizal fungi Russula aff. cuprea. Experimentally tests were carried out to see if these mice species have a preference to consume a specific structure of the fungus (pileus, hymenium or stipe). Also, we analyzed if the passage of this fungus through the digestive tract has an effect on the sporal metabolic activity. Our results indicate that although the whole sporocarp can be consumed, the hymenium (fertile part of the sporocarp) was the first structure selected by both mice species. Furthermore, we found that the passage of the fungus by the digestive tract of the 2 mice species does not have a significant effect on the sporal metabolic acivity (p= 0.06) of Russula aff. cuprea, suggesting that these mice species could be effective sporal dispersers of this epigeous fungi in the National Park La Malinche.
