Lepiota atrodisca, commonly known as the dusky parasol,[1] is a species of mushroom in the genus Lepiota. It is found in North America, South America,[2] and India.[3] Its edibility is unknown, but similar species are known to be deadly toxic.[4]
Lepiota atrodisca was first described by Stanford Myron Zeller in 1938.[5] DNA analysis has shown that L. atrodisca could actually be multiple species, only distinguishable through genetic sequencing.[1]
Description
The cap of Lepiota atrodisca is 1.5-5 centimeters in diameter, and has a dark-colored disc in the middle.[1] The stipe is about 2–8.5 centimeters tall and 1-4 millimeters wide, and the gills are white.[4]
Habitat and ecology
Lepiota atrodisca grows in leaf litter in forests, and is common in low-lying areas in the Pacific Northwest.[1] While it occasionally fruits during the summer and winter, it usually does so in the fall,[1] shortly after it rains.[4]
