This is Phlebia subceracea, previously known as Mycoacia subceracea, it is not listed in the database under either name so needs to be added please.
It is not always this orange looking, frequently having a more yellow appearance.
3 images, this looks very similar to the last species (Tubaria rufofulva), but lacks the annulus and has white spores, The gill edge is also coloured. This is an as yet unnamed species of Callistosporium, recorded as Callistosporium 'maroon with yellow rhizomorphs' in Gates & Ratkowsky - A Field Guide to Tasmanian Fungi. Could Callistosporium spp be added to the database please.
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.
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.
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.
Two images. This is Mycena roseoflava, could the database be update to include this species. The small pink caps can cover large areas on logs in wet forest. You might see a yellowish base to the stipes (stems) of some which is a clue to identification.
