Cyathus helenae

About

Cyathus helenae or Helena's bird's nest is a species of fungus in the genus Cyathus, family Nidulariaceae. Like other members of the Nidulariaceae, C. helenae resembles a tiny bird's nest filled with 'eggs'—spore-containing structures known as peridioles. It was initially described by mycologist Harold Brodie in 1966, who found it growing on mountain scree in Alberta, Canada. C. helenae's life cycle allows it to reproduce both sexually and asexually. One of the smaller species of Cyathus, C. helenae produces a number of chemically unique diterpenoid molecules known as cyathins. The specific epithet of this species was given by Brodie in tribute to his late wife Helen.
