The fungi in the rainforest at Booyong have fascinated me and I have to admit at this time I know little about them. I have been able to identify these stunning bright yellow fungi as Clavulinopsis amoena, previously known as Clavaria amoena. It belongs to the Clavariaceae family and has a bright yellow club like shape which is unbranched and can grow up to 11cm high.
It exists in a variety of habitats including eucalypt woodland, wet sclerophyll forest, rainforest and along creek banks and can grow solitary or in groups. It is a common fungus and is found in the autumn season.
This information was obtained from a wonderful Guide created by the Hunter Land Services called A guide to common fungi of the Hunter-Central Rivers region. I highly recommend it for new fungi enthusiasts like me.
