Lamprospora australis

The fruitbody is a stemless, reddish-orange to yellowish-orange disk up to 3 millimetres in diameter. The margin is raised and is tufted or fuzzy.

The fruitbodies appear on the ground amongst mosses and the species is reported to be a moss parasite.

The species was first described by McLennan & Cookson (see below) as Lamprospora areolata var. australis, based on specimens collected in Victoria (at Ringwood and near Castlemaine) in 1921. Rifai (see below) argued that this fungus was quite distinct from Lamprospora areolata and warranted recognition as a separate species. Both publications contain excellent drawings of microfeatures.

Look-alikes

Other species of  Lamprospora are macroscopically similar and identification to species requires a look at the spores. There are several genera of small, orangeish disk fungi, mostly without the raised, tufted/fuzzy margin. You find that type of margin also in some species of Octospora.
