Taxonomy and Phylogeny of Cystolepiota (Agaricaceae, Agaricales): New Species, New Combinations and Notes on the C. seminuda Complex

Researchers studied tiny mushrooms in the genus Cystolepiota using DNA analysis and microscopy to better understand their relationships and identify new species. They discovered that what was thought to be a single species called C. seminuda was actually multiple different species. They also found that another group of mushrooms called Pulverolepiota was distinct enough to deserve its own genus rather than being classified with Cystolepiota. This work clarifies the true diversity and proper classification of these diminutive fungi found worldwide.
