Hygrocybeae community of Lane Cove Bushland Park - endangered ecological community listing

Superseded Determination - retained for reference purposes
This Determination has been superseded by the

2014 Determination (Critically endangered ecological community listing) 

NSW Scientific Committee - final determination

The Scientific Committee established by the Threatened Species Conservation Act, has made a Final Determination to list the Hygrocybeae Community of Lane Cove Bushland Park as an Endangered Ecological Community under Part 3 of Schedule 1 of the Act. Listing is provided for under Part 2 of the Act.

The Scientific Committee has been found that:

1. The Hygrocybeae Community of Lane Cove Bushland Park is an assemblage of more than 20 species of fungi in the family Hygrophoraceae (Fungi, Basidiomycota, Agaricales, Hygrophoraceae).

2. The Community is restricted to a core zone along the Gore Creek catchment in the Lane Cove Local Government Area in Sydney. The majority of species occur in the warm temperate gallery rainforest centred on the banks of the north-eastern arm of Gore Creek and its tributaries in Lane Cove Bushland Park. This core zone also extends to the wet sclerophyll catchment, north of the tributary junction with Gore Creek. A minority of the species in the assemblage is found in a buffer zone of dry sclerophyll between the perimeter of Lane Cove Bushland Park and outer edges of the gallery canopy and along Gore Creek in Osborne Park.

3. The following species have been recorded in the community:

  • Camarophyllopsis kearneyi
  • Hygrocybe anomala var. ianthinomarginata
  • Hygrocybe astatogala
  • Hygrocybe aurantiopallens
  • Hygrocybe aurantipes
  • Hygrocybe austropratensis
  • Hygrocybe cantharellus
  • Hygrocybe cheelii
  • Hygrocybe chromolimonea
  • Hygrocybe erythrocala
  • Hygrocybe graminicolor
  • Hygrocybe helicoides
  • Hygrocybe involutus
  • Hygrocybe irrigata
  • Hygrocybe kula
  • Hygrocybe lanecovensis
  • Hygrocybe lewellinae
  • Hygrocybe mavis
  • Hygrocybe miniata
  • Hygrocybe reesiae
  • Hygrocybe sanguinocrenulata
  • Hygrocybe stevensoniae
  • Hygrocybe taekeri
  • Hygrocybe virginea

4. Other species in the Community have been collected but remain undescribed and unclassified, and other Hygrocybeae may be present.

5. Lane Cove Bushland Park is the holotype site for Hygrocybe aurantipes, Hygrocybe austropratensis, Hygrocybe lanecovensis, Hygrocybe anomala var. ianthinomarginata, Camarophyllopsis kearneyi and Hygrocybe reesiae. [Young, A.M., 1999, The Hygrocybeae (Fungi, Basidiomycota, Agaricales, Hygrophoraceae) of the Lane Cove Bushland Park, New South Wales. Austrobaileya 5: 535 - 564].

6. The assemblage is not known to occur outside the Lane Cove Local Government Area. Furthermore, the number of species of Hygrocybe is very high compared with other known sites in Australia and overseas. Species will not have above-ground fruiting bodies at all times of the year. There may be differences depending on seasonal conditions and other factors.

7. Within Lane Cove Bushland Park, different species of Hygrocybeae have been reported from one to several specific locations. More species occur at the southern than at the northern end of the Park. The ecological requirements of most species are poorly known, but are likely to be associated with a dense tree canopy and sandstone rocks.

8. The Community is threatened by water-borne pollutants. Industrial pollutants occur particularly in the upper reaches of Gore Creek catchment and domestic contaminants arise from residential properties on the perimeter of Lane Cove Bushland Park. The Community is also at risk from encroachment by exotic weeds, dumping of rubbish and garden refuse, excess pedestrian traffic in areas sensitive to erosion, and inappropriate bush regeneration measures that disturb the forest canopy and native understorey plants.

9. In view of the small area occupied by the Community and the threats to its integrity identified in 7 above, the Scientific Committee is of the opinion that the community is likely to become extinct in New South Wales unless the circumstances threatening its survival cease to operate.
