Assessment Notes

Favolaschia singeriana is a tiny sessile fungi associated to ferns in tropical ecosystems in the Neotropics. It has been registered just three times in 65 years. However, given its wide habitat potential and geographic distribution there should be numerous unknown subpopulations with many individuals each.

Justification

Just with three collections the species has a EOO of 1,685,456 km2 so the species fits the Less concern category.


Taxonomic notes

Favolaschia singeriana is a small, inconspicuous, resupinate, discoid, pruinose, white basidiomycete.
There are four Favolaschia species associated to ferns: F. alsophila Singer, F. singeriana, F. peziziformis (Berk. & M. A. Curtis) Kuntze, and F. pterigena Singer.
F. singeriana is distinguised from the other species by the spores size (7–10.5 × 4.5–7.5 μm) and small basidiomata (up to 1 mm).

Geographic range


Population and Trends

F. singeriana is a very rare small inconspicuous fungi only recorded three times in the Neotropics in 65 years. Given that it is associated to several tropical ecosystems in a wide EOO = 1,685,465 km2 there is a high chance to exist many more undocumented subpopulations and current information do not allow to infer its population size.

Population Trend: Uncertain


Habitat and Ecology

It is a saprotroph of fern leafs in tropical rain forest and mountain cloud forest.

Subtropical/Tropical Moist Lowland ForestSubtropical/Tropical Moist Montane Forest

Threats

Even while tropical forests and Mountain cloud forests are threatened by global warming and deforestation, F. singeriana associates to both ecosystems that currently have wide distribution in the Neotropics. The species is threatened in this moment.
