Agaricus globocystidiatus Drewinski & M.A. Neves, in Drewinski, Menolli & Neves, Phytotaxa 314(1): 68 (2017)


Why suggested for a Global Red List Assessment?

Agaricus globocystidiatus is a saprotrophic mushroom that grows on soil, usually gregarious. The species was recently described based on specimens collected in Santa Catarina and Paraná States, in Brazil. The species is currently known for Brazil and Mexico. In Brazil, A. globocystiatus was reported to Santa Catarina, Paraná (Drewinski et al. 2017) and São Paulo states (Ramos 2018). In Mexico, the species was reported to Coatepec city, located in the mountains of Veracruz State (Chen et al. 2019). The species is known for six sites in southern and southeastern Brazil, and one site in Mexico. Most specimens were found growing in urban areas. The population size is estimated in 70,000 – 87,500 mature individuals and there is no indication of population decline.


Geographic range

The species is currently known for Brazil and Mexico.
In Brazil, most collections were made in Florianópolis island, Santa Catarina State, at the campus of the Universidade Federal de Santa Catarina (27°36’08.0"S 48°31’29.0"W) in different dates (June 02, 2015; July 30, 2015; October 05, 2015; December 10, 2015; March 16, 2016; October 26, 2016; February 09, 2017); at the Parque Ecológico do Córrego Grande (27°35’56.0"S 48°30’39.0"W); and in a site in the Cacupé district (27°32’13.0"S 48°31’27.0"W).  In the state of Paraná, the species was found in the Parque Municipal das Araucárias (25°21’03.0"S 51°27’56.0"W), a fragment of the Mixed Ombrophilous Forest (Drewinski et al. 2017). In the state of São Paulo, the species was reported in two sites in São Paulo city: at the Universidade de São Paulo (23°33’25.4"S 46°43’22.4"W) and at the Parque Estadual das Fontes do Ipiranga (23°38’32.0"S 46°37’21.0"W) (Ramos 2018).
In Mexico, the species was reported to Coatepec city (Chen et al. 2019),  located in the mountains of Veracruz State, growing on a football field at the Unidad Deportiva Roberto Amorós Guiot (19°27’43.6"N 96°57’01.8"W).


Population and Trends

At the moment there are 13 collections of the species, most of them (9) are from Florianópolis island; one collection is from Parque Municipal das Araucárias and two collections are from São Paulo city. In Mexico, the species was reported for only one site. This is a species with medium to high detectability due to its size and gregarious growth.
A. globocystidiatus is known for six sites in southern and southeastern Brazil, and one site in Mexico, but is expected to be distributed along the neotropical region, in others 2.000 – 2.500 sites with 35 individual per site (13 collections / 6 sites * 2 multiplied factor * 8 ramets). The population size is estimated in 70,000 – 87,500 mature individuals. Because most of the specimens were collected in urban areas, there is no indication of population decline.

Population Trend: Stable


Habitat and Ecology

A. globocystiatus is a saprotrophic species that grows on soil, solitary to gregarious. In Brazil, the species was found growing mostly in urban areas, but also in Dense and Mixed Ombrophilous Forest (Drewinski et al. 2017). In Mexico, the species was collected in a football field, growing in a fairy ring of approximately four meter diameter (Chen et al. 2019).

Subtropical/Tropical Moist Lowland ForestUrban Areas

Threats

Due to the occurrence of the species in urban areas, there are no major threats to this species.


Conservation Actions

The few specimens collected in the Atlantic Forest (2) were found in municipal conservation areas. To guarantee the occurrence of these individuals it is necessary to maintain these protected areas.

Research needed

The species distribution is still poorly known. New collections are needed to confirm the wide distribution of the species throughout the neotropics.
