Not recorded since 1917.
Pileus: convex then applanate; up to 150 mm diameter; matt, somewhat irregular, grey brown at the centre, yellow brown towards margin.
Gills: adnate; crowded; white becoming cream; lamellulae present.
Stipe: cylindrical or attenuated at centre; 45 × 20 mm; fibrillose; white.
Spore print: white.
Spores: ellipsoid; 8 – 10.4 × 4.9 – 7.2 µm, average 9 × 5.7µm, average Q = 1.6; verrucose with an amyloid plage.
Cheilocystidia: not described by Cleland or Grgurinovic but might be expected to have terminal crystals.
A large fungus which is difficult to identify without a microscope. Melanoleuca is a genus that is not frequently found or identified to species level. As such it would represent a challenge to citizen scientists and encourage the use of microscopes and the adoption of rigorous identification techniques. It also commemorates the name of John Cleland a pioneer of mycology in Australia.
The two records from South Australia date from 1917. The fungus has not been reported from South Australia for over a century and must be presumed to be extinct.
The South Australian site at Mt Lofty is protected, but it is heavily used for recreation. Nearby Beaumont where Cleland also found this species is largely urbanised. The site has been visited regularly by mycologists as it was known as one of Cleland’s main collecting sites. The absence of any records for over a century suggests that the fungus is now extinct in South Australia.
List as extinct.
Continued observation recording at Mt Lofty.
