Registro Preliminar de Macrohongos (Ascomycetes y Basidiomycetes) en el Bosque Húmedo Montano del Alto El Romeral (Municipio de Angelópolis, Departamento de Antioquia - Colombia) Preliminar Report of Macrofungi (Ascomycetes and Basidiomycetes) in the Romeral's Montain Humid Forest (Angelopolis, Antioquia - Colombia)

Macrofungi play an important role in nutrient cycling. Especially, they are important drivers in the carbon cycling and in the organic matter decomposition process in tropical forests. In Colombia the knowledge on diversity of this group is still very poor. Through this work we intend to contribute to this knowledge. The macrofungi diversity was assessed on three different substrates on a 4 ha wet montane forest in the Antioquia province during five months. Forty species of macrofungi (two of them possible new species to science) belonging to 34 genera and 18 families were recorded. Marasmiaceae was the most diverse family with five species followed by Boletaceae, Polyporacea and Russulaceae with four species each one. Hypholoma, Lactarius and Marasmius were the most important genera with three species each one. Auricularia delicata (Fr.) Henn., Xylaria polymorpha (Pers.) Grev. y Ganoderma applanatum (Pers.) Pat. were the most frequently found species. The highest species numbers were growing on dead wood (19 species) and the lowest were recorded on litter (six species).
