This species now has a new name - Hymenotorrendiella eucalypti, could this be updated please, The tiny cups are around 1-1.75mm in diameter and they only occur on the leaves of the Blackwood, Acacia melanoxylon in wet forest. Like much of Australia's fungi, this species was named from collections sent overseas, in this instance M. J. Berkeley described it's habit as "on leaves of Eucalyptus", hence the naming error.
Several images. This species was believed to be associated with Myrtle Beech, Nothofagus cunninghamii, but now I have located it at two locations in the Wombat Forest plus there is a record to the north of Macedon. Like its near namesake, it could be a Gliophorus soon.
Three images, this is Deconica horizontalis, previously recorded as Melanotus hepatochrous in one field guide and as Psilocybe hepatochrous in another guide. It appears on ALA, could the database be updated please.
It is similar to the previous species but has purple/brown spores.
This image shows the full development of the species with tiny furry buttons on the far left through to collapsing and spent mushroom on the far right. Second images shows closer detail of the main group.
An as yet unnamed species but reported in the Gates & Ratkowsky publication A Field Guide to Tasmanian Fungi as Cystolepiota sp. 'small white'. The daggy bits hanging off the edge of the cap and the white gills are indicative of the species. Two images.
