Assessment Notes

Taxonomic notes

Macbrideola spinosispora is characterized by its small size, the violaceous colour of the sporotheca, the loose, flexuous and scanty capillitium, the hollow stalk with a yellowish brown base and specially the spiny spores (Walker et al., 2014; Treviño-Zevallos and Lado, 2020).

Why suggested for a Global Red List Assessment?

Macbrideola spinosispora was recently described, in 2014, in Costa Rica, 5 years later was collected for the first time in Peru and Brazil, seems to be a Neotropical species rarely collected and associated to specific substrate: leaf litter.

Geographic range

Macbrideola spinosispora is only known in 3 countries, was recently published one record from Peru (Treviño-Zevallos and Lado, 2020) and one record from Brazil (unpublished) in Alagoas state. Theses latest records are not in GBIF.

Population and Trends

There are 3 records among 3 countries.

Population Trend: Uncertain

Habitat and Ecology

All records of Macbrideola spinosispora are from moist chamber cultives using leaf litter, Treviño-Zevallos and Lado (2020) suggested that this species is foliicolous and adapted to tropical areas. In Brazil, the first and only record is from leaf litter of Atlantic forest.

Subtropical/Tropical Moist Lowland ForestSubtropical/Tropical Moist Montane Forest


In Brazil, Macbrideola spinosispora so far was found in Atlantic Forest, a hotspot that have been losing its biodiversity due to human actions.

Research needed

In Brazil are necessary field collections in others states and moist chamber cultives in order to know the distribution of this species, besides molecular biological techniques.
