Scientific name: Hygrocybe griseoramosa
Gazetted date:
20 Dec 2002
Profile last updated:
13 Nov 2024
Description
A small buff to brown gilled fungus. Cap 20 -30 mm, sepia brown to chocolate brown at the centre but becoming light pinkish buff either as the surface dries or with age, convex becoming upturned and wavy at the margins, ridged surface when moist and fresh, dry, smooth margins, even. Gills fused with small formations down stem but becoming deeply formed down stem as the cap becomes wavy at the margins, grey, often extensively veined on gill faces and on the cap undersurface, frequently branching into two near margins, margins even and of same colour. Stem 20 - 35 mm x 2 - 5 mm, pallid to light grey, smooth but with fine silky fibres, dry, solid but may become hollow with age, tapered towards base. No distinct odour present. Spore print white.
Distribution
Originally know from type locality at Lane Cove Bushland Park, Lane Cove however may also occur elsewhere in the region. Other possible locations include Chatswood, Royal National Park, Wolli Creek and the Blue Mountains (Springwood, Mt Wilson).
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 Hawkesbury Soil Landscapes with naturally low fertility and erodible.
- 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.
