Assessment Notes

Taxonomic notes

Without any synoyms reported, this speciess well characterized by the combination of a reddish brown, warty exoperidium
that breaks off, cream endoperidium, subglobose to
irregular spores up to (5–)5.7 3 6.25(–8.7) mm, which
under SEM have thin verrucose spines that are solitary
and form crests toward the apiculus, a contorted and
striate stipe, a deep socket with up to six dentate
membranes and a mouth plugged by clamped,
hyaline hyphae incrusted with fusiforms calcium
oxalate crystals.

Why suggested for a Global Red List Assessment?

Gasteroid fungi are a very well documented group in central and northern Argentina. Most species present wide distribution ranges bus this species was only recorded prom its type location, in the central forests dominated by the endemic tree Polylepis australis, which ins endangered due to reduction, invasion and cattle load.

Geographic range

Population and Trends

Given the great sampling efforts and the fact that no further reports were made, we can assume that the population, meassured in fruiting bodies, is pretty small. This is also supported by deep revisions of herbarium materials of gasteroid fungi from the surrpounding provinces without matches with this species. We provissionally assign a a population number of 500.  The species seem to be restricted to the Polylepis australis forests.

Population Trend: Decreasing

Habitat and Ecology

Saprotrophic on soil and litter in dry Polylepis australis forests.

Subtropical/Tropical Dry Forest


Soil and litter modification by heavy invasions. Ligustrum lucidum and Phyracantha coccinea are the main tree species invading these forests and research show that at leas L . lucidum heavily midifies the substrate conditions.

Named species

Conservation Actions

Strict meassures are needed to control the advance of the invasive species without compromising the gene flow between forest patches

National level

Research needed

There are many ongoing research lines on invasive species in this area but lines involving citizens would help improve the chances, since a massive effort is needed to control these species
