Abstract
ABSTRACT The study of Colombian agaricobiota is relatively recent. The training of new researchers has allowed more taxonomic surveys, increasing the literature on the subject and indicating the relevance of ecological and conservation studies. During a field survey conducted in the oak forests (Quercus humboldtii) in the Madre Monte Nature Reserve, municipality of Arcabuco - Colombia, in October 2018, about 40 specimens of Agaricales mushrooms were collected. The species were identified following the usual methods in Agaricology of the Laboratorio del Grupo de Investigación Biología para la Conservación de la Universidad Pedagogica y Tecnológica de Colombia. We identified a few species: Campanella elongatispora Singer, Cheimonophyllum candidissimum (Berk. and Curt.) Singer, Marasmiellus bolivarianus Singer, and Pluteus chrysophlebius (Berk. and Curt.) Sacc., which were added as new citations to Colombia. An increase in the area of occurrence of certain species of Agaricales-mushrooms was also reported.
Highlights
The first records of Agaricales fungi of Colombia were published by Chardon (1928), which detailed the research investigations carried out in the country
The most current reports indicate that there are at least 1239 species of macrofungi registered, of which 1058 are Basidiomycota; and 537 of these are Agaricales; these are reported in 130 publications in Colombia alone (Vasco-Palácios & Franco-Molano 2013)
Paleoecological (Palynology) testimonies on the presence of the only species of oak (Quercus humboldtii) in Colombia dates to 450,000 years ago; these trees are found in the mountains around of the savanna of Bogotá
Summary
The first records of Agaricales fungi of Colombia were published by Chardon (1928), which detailed the research investigations carried out in the country. The most current reports indicate that there are at least 1239 species of macrofungi registered, of which 1058 are Basidiomycota; and 537 of these are Agaricales (plus 63 of Russulales); these are reported in 130 publications in Colombia alone (Vasco-Palácios & Franco-Molano 2013). Most of the research studying fungi of Quercus humboldtii forests began in the last century, mainly by Singer, (1963, 1970a, 1970b, 1976), Dennis (1970), Pineda et al, (1988), Velásquez et al, (1988), Halling (1989), Horak & Halling (1991), Guzmán (1983), Franco-Molano et al, (2000), Montoya et al, (2005), López-Quintero et al (2007), Peña & Enao (2014) and others. No recent work on the taxonomy of saprophytic fungi in the oak forest is available
