''Marasmius wynneae'' (sometimes incorrectly spelt ''Marasmius wynnei'') is a species of
gilled mushroom found in European woods.
Naming
This species was originally described in 1859 by the mycologists
Miles Joseph Berkeley and
Christopher Edmund Broome in the British "Annals and Magazine of Natural History".
[ The original collection was done on the Coed Coch estate in Denbighshire, Wales, which then belonged to the Wynne family. The entry for the new species explicitly mentions Mrs. Wynne, and so it is clear that the mushroom was named for her and not her husband.][ A Latinized species name takes the genitive ending -i (or -ii) if it is dedicated to a man and it takes -ae (or -iae) if it is for a woman. Therefore, the spelling ''wynneae'' is correct here, even though the spelling in the original description of the species was ''wynnei''.][
In English this fungus has the common name "Pearly Parachute".][
