Spores dull, subhyaline to pale yellow when examined directly from soil but light yellow and shiny from loss ofthe outer mucilaginous wall when centrifuged in sucrose; spores globose or subglobose, (55-) 75-90(-100) ixm diam or occasionally ellipsoidal or irregular, 100-115 x 66-98 /um; composite spore wall 2.5-5 ixm thick, of separable portions distinguishable on broken spores.
Due to the several records worldwide, we suggest this species to be categorized as Least Concern (LC).
Originally found in West Virginia in soil associated with Andropogon virginicus. In Brazil, this species was registered in the states of São Paulo (3), Bahia (2) and Petrolina (1). However, that number is still underestimated.
On a global scale, this species is registered in 12 countries.
Population Trend: Improving
In Brazil, this species is registered in different biomes, such as Amazon rainforest, Cerrado, Atlantic rainforest, Caatinga and Pantanal
This species is associated with biomes that have high rates of anthropic disturbance, such as deforestation. This condition may indicate a risk.
The multiplication of this fungus in the laboratory, being kept in the inoculum bank represents an advance for the conservation of this species.
More studies are needed that address the ecology of the species and its hosts, in addition to increasing data on its distribution.
