Assessment Notes

Crinipellis mexicana has only three records worldwide (Mexico, Bolivia, Austria) in 100 years. In these locations the vegetation are mountain forests, from the subtropical ones in the Neotripcs to the temperate ones in Austria.

Justification

Even while the species is rare, given its wide habitat and geographic range its population is considered not threatened.


Taxonomic notes

Crinipellis mexicana has a chestnut to rusty-brown pileus, strongly pilose. Lamellae cream white, sub-close to moderately close, not ventricose, and free. Stipe, densely and strongly to sparsely and weakly pilose all over. Few cheilocystidia, making the edge of the lamellae heteromorphous; cheilocystidia characteristically entire and not apically appendiculate or only rarely with three-finger like appendages. KOH on dried pileus deeper dull brown. It could be confused with C. patouillardii, but it has differences in basidiome size and cheilocystidia abundance and shape.


Why suggested for a Global Red List Assessment?

Crinipellis mexicana has only three records worldwide (Mexico, Bolivia, Austria) in 100 years. In these locations the vegetation are mountain forests, from the subtropical ones in the Neotripcs to the temperate ones in Austria. Even while the species is rare, given its wide habitat and geographic range its population is considered not threatened.


Geographic range

The species was described based on two materials, one from mountain cloud forests in Xalapa, Mexico, and another from Nor-Yungas, La Paz, Bolivia. It was recognized as a Neotropical species by Singer (1976). There is another record also done by Singer in Austria, Niederösterreich. So, given that the species was described by Singer and the three known materials were studied by him we assume that the species distributes in the Neotropics and also it can be found in Europe.


Population and Trends

Only three collections are known: Mexico, Xalapa; Bolivia, La Paz, Nor-Yungas; Austria, Niederösterreich. These occupy a wide are covering at least the Neotropics and also Europe. In the three locations the vegetation are mountain forests, from the subtropical ones in the Neotripcs to the temperate ones in Austria. Given the wide geographic range and the species and its wide habitat range, its population is considered not threatened.

Population Trend: Uncertain


Habitat and Ecology

Gregarious. On sticks and fallen twigs of dicotyledons (Piperaceae sp.) in mountain forests, from the subtropical ones in the Neotripcs to the temperate ones in Austria.

Temperate ForestSubtropical/Tropical Moist Montane Forest

Threats

Given the wide geographic range and the species and its wide habitat range, its population is considered not threatened. However, on the regional scale the subpopulations of Mexico are threatened as it develops in mountain cloud forest. In Mexico this ecosystem in severely threatened by global warming.

Conservation Actions

By now, there are a few areas in the type location (Xalapa, Veracruz) under a conservation status. Crinipellis mexicana is a rare fungus, not listed on any national or international Redlist.


Research needed

To perform phylogenetic analysis comparing the specimen of Crinipellis mexicana from Xalapa and Bolivia and Austria, in order confirm they are conspecific. Also, include sequences of close-related species (like C. patouillardii) to verify the relationships among species of the genus, and possibly found new occurrences. Furthermore, this would highlight if some herbaria specimens could have been misidentified. An increase in sampling effort to locate some other populations of the species, particularly in mountain cloud forests near the type locality. Being a saprotrophic species could be less constricted to its host.
