New citations to the agaricobiota (Fungi - Basidiomycota) in oak forests of the Northeastern Andes of Colombia

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.

New records of Agaricaceae (Agaricales, Basidiomycota) from Colombia

“…The area studied in Santa Marta city is extremely small, and there are still large unexplored areas. In the last 40 years, macro-fungi studies have been concentrated mainly in the Andean region, with 83% of the species from that region and only 6% from the Caribbean region (Pulido 1983;Pineda et al 1988;Franco-Molano and Uribe-Calle 2000;Franco-Molano et al 2010;Vasco-Palacios et al 2013;Palacio et al 2015;Lombana et al 2016;Putzke et al 2020). Therefore, we provide an important contribution to the inventory of Agaricales of the Caribbean Plain biogeographic region where the fungi diversity is high and almost unexplored.…”

“…In Colombia, Agaricales is the order of fungi with the greatest number of species, with 544 known (Putzke et al 2020;Vasco-Palacios and Franco-Molano 2021) of the total of 16,071 macrofungi of the phylum Basidiomycota worldwide (He et al 2019;Wijayawardene et al 2020). Most species, 83%, are recorded from the Andean region, followed by the Caribbean region with 6%; 11% is distributed in the rest of the country (Franco-Molano and Uribe-Calle 2000;Franco-Molano et al 2010;Franco-Molano 2013, 2021).…”

Madre Monte Natural Conservation Area in the Colombian Andes as Model for Preservation of Fungi in Quercus humboldtii Forests

“…The species were identified using the usual taxonomic works available to Colombia and South America [2,3,5,9,11,13,16].…”

“…(originally from Australia) are being introduced for this reason too. Seven species of Agaricales were preliminary reported to this preservation area, with 4 new occurrences to Colombia [9].…”

Small reserves as hotspots for Fungi preservation in Brazil

“…The lack of knowledge is one of the major problems relating to fungi preservation, especially in South America, where countries with high biodiversity numbers like Brazil and Colombia, which have incomplete fungal species lists, are still beginning to study the complex ecological role of this group (Putzke & Putzke 2017;Putzke et al 2020Putzke et al , 2021. But it is also a problem to all the world since only 56 species of fungi have their status evaluated globally by the UCN red list (Hawksworth et al 2017).…”
