Cruentomycena viscidocruenta is a small introduced mushroom with caps of around 7-8 mm across, brilliant red, hemispherical and it flattens as it matures so that the centre is depressed, margins are striate. 
The flesh and stem are the same colour as the cap, but the gills are sometimes a little paler. There is no ring or volva, and the cap can be quite viscid especially in wet weather. The stem is slender and hollow and up to 4 cm long and is sticky or slimy when wet as is the cap. The spore print is white.
It 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.
