The fruiting body of this species is best described as a white to creamy sheet with numerous short teeth. This was found growing on rotten wood in a suburban garden. The white box in Photo 2 outlines the area shown in Photo 1. Many species of Hyphodontia have short teeth that are obvious to some degree to the naked eye (but note that other genera of such 'flat' fungi may also be toothed). The teeth of Hyphodontia floccosa have long tubular cells that protrude to such an extent that they can be seen with the help of a hand lens (or a macro lens on a camera). Depending on the quality of your eyes, you may even be able to see, with the naked eye, that the teeth are not smooth. I show a close view of the teeth in Photo 3. The material is preserved as collection number HL 6122 at the Australian National Herbarium, Canberra.
