Today, a brief entry along the lines of the recent run of autumn-coloured photographs, though it was taken during the Australian winter in late July. This photograph of the stunning red Cruentomycena viscidocruenta (Mycena viscidocruenta) is courtesy of Ken Beath (kjbeath@Flickr).

Commonly known as a ruby bonnet, Cruentomycena viscidocruenta is found in New Zealand and southern Australia (including New South Wales and Victoria). Via Discover Nature at James Cook University's article on Cruentomycena viscidocruenta, ruby bonnet has a cap that is 1-2cm in diameter, with the caps being convex when young and tending to flatten with maturity. The hollow stipe of ruby bonnet is up to 4cm long and 0.5cm wide. According to the Taranaki Educational Resource: Research, Analysis and Information Network (TERRAIN)'s article on ruby bonnet, "[Cruentomycena viscidocruenta] is usually found in small groups attached to small sticks and leaves especially in moist gullies in native forest, urban scrub and wood chip gardens".

As shown in Ken's photograph, Cruentomycena viscidocruenta is slimy when wet. The epithet viscidocruenta stems from the Latin viscos meaning "sticky" and the Latin cruent meaning "bleeding" or "bloody".

Additional photographs are available via New Zealand's Hidden Forest: Cruentomycena viscidocruenta, as well as a declaration on edibility ("No"). Mushroomobserver.org also has more photographs, along with a brief discussion on the possibility of using this species for dying clothes.
