Assessment Notes

Taxonomic notes

Agrocybe perfecta was erected based on Pholiota vermiflua var. perfecta Rick 1938. The species seems to be confused with other species in Agrocybe based on different subspecies of Pholiota vermiflua described by Rick.


Why suggested for a Global Red List Assessment?

This is a rare species known only from Montane environments of Southern Brazil, Argentina and Bolivia, in the Araucaria forests and the Yungas. Total population is estimated at 5,000 to 10,000 mature individuals, distributed in 500 sites with up to 20 mature individuals per site, where each functional individual accounts for 2 mature individuals. A population decline of 20-30% is projected to occur in the next 20 years (3 generations length) due to deforestation, impact of introduced species (mainly cattle), and climate change.


Geographic range

Montane environments of Southern Brazil, Argentina and Bolivia, in the Araucaria forests and the Yungas (Rick 1938,Meijer 2006, Melgarejo-Estrada 2020, Niveiro et al. 2020). It is expected to occur along these environments and potentially along the montane environments of southern and southeastern Brazil, at the Serra do Mar mountain range.


Population and Trends

Agrocybe perfecta is a rare species, with less than 20 records. It is found in Montane environments, most notably Cloud Forests, both in Southern Brazil (Araucaria Forests) and in the Eastern Andean Forests (Yungas) (Niveiro et al. 2020). These habitats are historically deforested and fragmented (Carlucci et al. 2016, Manrique et al. 2018), and a population decline associated with loss of habitat of 20-30% is projected to occur in the next 20 years (3 generations length) due to deforestation, impact of introduced species (mainly cattle), and climate change (Mulligan et al. 2011,Carlucci et al. 2016, Wicaksono et al.2016, Castro et al. 2020 ). Total population is estimated at 5,000 to 10,000 mature individuals, distributed in 500 sites with up to 20 mature individuals per site, where each functional individual accounts for 2 mature individuals.

Population Trend: Decreasing


Habitat and Ecology

The species is saprophytic, growing on litter, soil and dung in subtropical montane forests (Niveiro et al. 2020).

Subtropical/Tropical Moist Montane Forest

Threats

The species occurs in fragmented, historically affected forests, and is threatened with the loss of its habitat from the impacts of climate change, as well other anthropogenic factors, such as deforestation and introduction of invasive species.

Research needed

More studies with broad sampling along areas with appropriate habitat are desired to understand its full distribution. Additionally, systematic studies with molecular phylogenetic data can help understand the evolution of the species, but no sequences are available online.
