Fungi are fabulous and are amongst the most numerous organisms on earth. Because of the ephemeral nature of their fruiting bodies they are not as well known as other organisms. When these small (12mm diameter) balls appeared in the sand at Kabulwarnamyo Ranger Station I was so impressed and intrigued that next time I was at a good bookstore I bought Bruce Fuhrer’s Field Guide to Australian Fungi in the hope I might be able to identify them. I’m fairly certain the genus is Calostoma, because three of the four Calostomas pictured and described are the only fungi in the book that look anything like these. The closest in appearance, and possibly, the correct species is Calostoma fuhreri which shares the black body with red coloured orifice which to my eye resembles Chinese characters. The name Calostoma means beautiful mouth.
