Description
Small, brightly-coloured gilled fungus. Cap 7 - 30 mm, convex then becoming rather flattened and occasionally centrally depressed, dry, smooth or sometimes mealy, brilliant crimson, margins scolloped forming (especially when young) to even, not cracking, may be yellow tinted. Gills broadly fused froming slightly down to tooth, thick, widely spaced, pure white becoming cream coloured with age, margins of same colour; veins often present on the upper gill surfaces and on the cap undersurface. Stalk 11 - 35 x 2 - 3 mm, more or less cylindrical although occasionally with a tendency to become flattened and frequently is twisted/curved, firm, smooth, dry, at first brilliant crimson, but paling with age and may become pinkish cream, the base has a tendency to become yellow tinted and this may spread upwards. Odour none, taste mild.
Distribution
Known in a few locations including in Lane Cove Bushland Park and the Blue Mountains in NSW and in areas of south-east Queensland. However little information exists for populations outside Lane Cove Bushland Park.
Habitat and ecology
- Occurs in gallery warm temperate forests dominated by Lilly Pilly Acmena smithii, Grey Myrtle Backhousia myrtifolia, Cheese Tree Glochidion ferdinandi and Sweet Pittosporum Pittosporum undulatum.
- Associated with alluvial sandy soils of the Hawesbury Soil Landscapes.
- Occur as individuals or in groups, terrestrial rarely on wood and only if extremely rotten; substrates include soil, humus, or moss.
- Does not produce above ground fruiting bodies (fungus) all year round. Fruiting bodies begin appearing mid May to mid July sometimes to August.

Threats
- Damage or loss due to changes in water quality and volume, particularly industrial pollutants and domestic contaminants.
- Damage and loss of habitat due to weed encroachment and inappropriate bush regeneration measures that disturb the forest canopy and native understorey plants.
- Damage and loss of habitat due to encroachment of access tracks into unstable and sensitive areas.
- Lack of understanding of habitat requirements, ecological processes and associations between fungi, their habitat and other species.
- Inappropriate fire regime.
