Small, fragile, 10cm tall. In leaf mould in heavy shade, lowland spring-fed monsoon forest, on drier part towards margin.

This is a normal gilled mushroom that has a very thin cap flesh, which splits radially (between the gills). Further drying lifts and twists the gill-segments into the flower shape in the image. The type specimen from Vanauatu had the same form on all fruitbodies, but the author was unsure whether this was an oddity, or the normal condition. The find of this Australian specimen shows that it is the norm, but it would be great to find young fruitbodies to understand exactly of the final form develops – at what point in development does it depart from a mushroom shape?

The species is Hausknechtia floriformis, a monotypic genus only described in 2020, with a single species described (by Anton Hausknecht) in 2003, previously only known from Vanuatu. I have been on the lookout for it, great to know it occurs in Australia too.
