Assessment Notes

Taxonomic notes

An interesting agaric with a marasmioid habit was collected and describe in Quercus humboldtii forest in western Colombia. Substrata: Scattered to gregarious on Quercus leaves.
Distribution: Known only from Colombia and Costa Rica.


Why suggested for a Global Red List Assessment?

Gloiocephala quercetorum is a tiny, viscid and white agaric that grows in mountain areas under Quercus humboldtii . Habitat loss and degradation are threatened. In Colombia Quercus humboldtii are categorised as vulnerable VU and populations are scarce and fragmented. There are not enough information about the trend of the population. However, based on the this species should be listed as Vulnerable.


Geographic range

Colombia:  Antioquia, Boyacá, Huilo Nariño, Santander and Tolima (Herbarium material HUA, Andes; Vasco-Palacios & Franco-M 2013, Vargas & Restrepo 2019).  8 specimens HUA and 8 Andes

Costa Rica: Limon and Alajuela provinces


Population and Trends

Gloiocephala quercetorum is terrestrial,  growing in soil and litter. This saprophytic species It has been recorded in Oak forests in Costa Rica and Colombia.

Habitat and Ecology


Threats

The main known threat to Gloiocephala quercetorum is the habitat declining and fragmentation due deforestation and the decrease of it host species Quercus humboldtii populations (Gallagher 2018).  Despite this species is saprophytic, only has been found in oak forests. Anthropogenic pressure on oak forests and the habitat degradation is mainly due to land use change, logging, deforestation, urbanization. In addition, timber extraction carried out in for the production of charcoal and the use of the wood is used in the construction of houses and furniture generates a great impact in oak populations (Cárdenas & Salinas 2007, Nieto & Rodriguez 2010). Almost 42% of Quercus humboldtii populations have undergone in an intense process of decline and it is in the vulnerable category (VU A2cd) for Colombia (Gallagher 2018).

Conservation Actions

Habitat protection and management of habitats should be considered as conservation actions for this species.

In Colombia, populations of the hosts tree, Quercus humboldtii, can be found in a couple of protected habitats, including the slopes of Nevados del Puracé and Huila, Parque Nacional Darién, los guacharos National Park, and biological reserves on private land (Cárdenas & Salinas 2007, Gallagher 2018).

Research needed

Research is needed to evaluated population trends. Also more distributional data are needed, and studies with DNA for phylogenetic inference and molecular characterization for ecological studies. A taxonomic review of the collections deposited in the Colombian herbaria should be carried out, where are many unidentified bolete specimens.
