Discinella is a small genus of Ascomycete fungi, Their fruiting bodies are bright yellow to yellowish-orange coloured discs up to 10 mm in diameter that grow in the dirt amongst the sclerophyll litter on the Eucalypt forest floor. It is found Australia-wide in such forests. I have only seen these in Winter, and in wet conditions – They are not to be confused with the yellow discs of Bisporella citrina, which grow on wood.
