Thank you so much Neil. I was lucky to find various stages of the fungus. The wood chips had been brought in for erosion control.

Congratulations Brian, your Woolly Bird Nest Fungi are our Spotting of the Day:

"They look like delicate white cups filled with pulses! These Woolly Bird Nest Fungi (Nidula niveotomentosa) are our Spotting of the Day. The genus Nidula (from the Latin nidula, meaning "little nest") belongs to the fungus family Agaricaceae. The white woolly cups (called peridia or splash cups) are the fungus's fruiting body, while the small brown discs are known as peridioles and contain spores. The cups develop with a covering which, once cracked open, exposes the peridioles. These can in turn be hit by raindrops which will eject them from the nest and contribute to spore dispersal".
