“…Although inventories of EM fungal fruiting bodies and root tips have been made in oak-dominated forests in Central America (Halling and Mueller 2005;Mueller et al 2006;Morris et al 2009), this is one of the first belowground surveys of EM fungi in a tropical montane forest and provides insight into the diversity of EM fungal species associated with Oreomunnea across sites varying in fertility and in the amount and seasonality of rainfall. The rationale for this project was to provide information for future experiments that will explicitly test for the existence of mycorrhizal networks and their effects on Oreomunnea seedling performance.…”

“…Notably, the ECM genus Hebeloma reported for Panama based on the STRI fungi checklist, has not yet been encountered at Fortuna. Also, absent from the STRI check list, and yet to be collected at Fortuna or sequenced from roots, is the genus Tricholoma, known to occur in the oak forests of Colombia and Costa Rica (Halling and Mueller, 2005;Mueller et al, 2006).…”

Panamanian montane forests harbor a high diversity of fungi, particularly of ectomycorrhizal (ECM) fungi, however their taxonomy and diversity patterns remain for the most part unexplored. Here we present state of the art fungal taxonomy and diversity patterns at Fortuna Forest Reserve based on morphological and molecular identification of over 1,000 fruiting body collections of macromycetes made over a period of five years. We compare these new results with previously published work based on environmental sampling of Oreomunnea mexicana root tips. We compiled a preliminary list of species and report 22 new genera and 29 new fungal species for Panama. Based on fruiting body collection data we compare the species composition of ECM fungal communities associated with Oreomunnea stands across sites differing in soil fertility and amount of rainfall. We also examine the effect of a long-term nitrogen addition treatment on the fruiting body production of ECM fungi. Finally, we discuss the biogeographic importance of Panama collections which fill in the knowledge gap of ECM fungal records between Costa Rica and Colombia. Given that the isthmus of Panama was an important migration route of ECM tree and fungal species from northern temperate areas to South America, the ECM fungal communities of Panama might show a high degree of isolation and therefore a high level of endemism. We expect that the forests at Fortuna will continue to yield new ECM macromycete data as we continue to study the collected specimens and describe new species.

“…Es bien conocido que la destrucción y fragmentación de hábitats conduce a una disminución de la biodiversidad a escala local, regional y global y este efecto se incrementa cuando se suman cambios climáticos (Kappelle, Van Vuuren, & Baas, 1999;Mueller, Halling, Carranza, Mata, & Schmit, 2006;Oosterhoorn & Kappelle, 2000). Los hongos son uno de los grupos de organismos que se ven más afectados por estos cambios, ya que muchas variables influyen en su desarrollo, y, por lo tanto, en su diversidad.…”

RESUMEN: Se estudió la presencia de macrohongos en troncos caídos de roble en dos bosques montanos neotropicales en Costa Rica durante los años 2008-2012. Se seleccionó un bosque maduro (aprox. de 200 años) y uno en proceso de regeneración (32 años). Se identificaron 181 taxones (80 especies y 101 morfoespecies). Un número similar de especies se presentó en ambos bosques, aunque la composición de éstas fue diferente en cada uno. De acuerdo a los resultados obtenidos, se sugiere que los porcentajes de especies diferentes y compartidas para cada bosque, pueden representar cada uno un tercio de la diversidad presente en estos bosques. Xylobolus subpileatus e Hymenochaete rubiginosa fueron las especies más comunes. Varias especies de hongos ectomicorrízicos se encontraron sobre los troncos caídos, pertenecientes principalmente a los géneros Inocybe, Cortinarius, Laccaria, Leccinum y Russula. Se discute la relación entre la aparición de los cuerpos fructíferos y las condiciones ambientales presentes durante el periodo de estudio; así como la importancia de la conservación de estos bosques en procesos de regeneración. Palabras clave: macrohongos de la madera, macrohongos en troncos caídos, bosque neotropical montano de roble, diversidad fúngica, dinámica de hongos, robles, Costa Rica, conservación. ABSTRACT:The presence of macrofungi on dead oak wood was studied in two neotropical montane forests in Costa Rica during 2008-2012. The two sites chosen for the study were a mature forest (approx. 200 yr. old) and a secondary forest (32 yr. old). One hundred and eighty-one taxa (80 species and 101 morpho species) were identified. A similar number of species was present in both forests, but there were some differences in the species composition of each forest. According to the results, it is suggested that the percentage of different and shared species could each represent a third of the diversity present in these forests. Xylobolus subpileatus and Hymenochaete rubiginosa were the most common species in both forests. Several ectomycorrhizal species were found growing on logs, and the genera most commonly found were: Inocybe, Cortinarius, Laccaria, Leccinum and Russula. The relationship between fungal fructifications and the environmental conditions present during the
