Assessment Notes

Blumenavia toribiotalpaensis is a rare, distinctive and unique fungus with a restricted distribution to western Mexico where only two subpopulations are known. One of this is threatened by agriculture shifting.

Justification

Assuming 10 potential subpopulations with no more that 1000 mature individuals each, the species has less than 10000 mature individuals in few populations expected to decline by habitat loss. In consequence it should be listed as Vulnerable based on C2a(i) criteria.


Taxonomic notes

This phalloid fungi is characterized by 3-4 white to beige branches. It is differentiated from B. rhacodes B. angolensis as its gleba is only present on the apex of the branches.

Geographic range

The fungi is assumed to be endemic from western México, in Jalisco. There is one unconfirmed record in Nuevo Leon, México.


Population and Trends

The first observation of this fungi comes from 2002. Since then, only two collections exist from two subpopulations and a recent observation from 2017. All collections and observations belong to the same region in western Mexico in Jalisco state. Given its distinctive fruit body and the fact that Jalisco fungi are extensively studied, we assume that the species is very rare and endemic to this region with only two subpopulations. Its population affected by habitat loss and fragmentation.

Population Trend: Uncertain


Habitat and Ecology

Gregarious on leaf litter, under Pinus spp, Carpinus caroliniana and Acer saccharum subsp. skutchii. It inhabits in transitional subtropical Pine - Cloud forests 1800 msnm. Distributed on patches along an area of 100 m2.

Subtropical/Tropical Moist Montane Forest

Threats

One of the two known subpopulations is threatened by land use change because of logging and shifting agriculture.

Shifting agriculture

Conservation Actions

To protect the sites where know populations exist.

Site/area protection

Research needed

DNA studies are lacking and extensive monitoring of the area are needed to map the population.
