Sclerocystis clavispora previously assigned as Glomus clavisporum is recognized by sporocarps globose to subglobose, brownish black to black, minutely verrucose from exposed tips of spores formed radially in a single, tightly packed layer around a central plexus of hyphae; base indented; peridium lacking (Trappe, 1977).
We suggest this species to be categorized as Least Concern (LC).
This species is known in four countries. However, it can possibly be found in other countries.
There are two records only Brazil according to GBIF. However, it can be found in other countries too.
Population Trend: Uncertain
In Brazil, the species is found in the Caatinga, Amazon, Atlantic Forest and Cerrado.
In Brazil, this species can be found in Tropical rainforest and Tropical Dry Forest. These forests currently have higher rates of deforestation, especially the Atlantic Forest, which is considered a hotspot.
Most records are in area with native vegetation of Brazil. The isolation of this fungus in controlled conditionrepresents an advance for the conservation of this species.
Other areas should be studied in order to assess the distribution of this species.
