Saproamanita sp.

Description:

This spotting was over a 2 day period. Two separate specimens that were only a metre apart, with photos 1-4 showing the smaller one (about 12-15 cms in diameter), and 5-6 the larger (over 20 cms in diameter). I'm not too sure what to make of this spotting. I thought it would quite easy to ID because of the shaggy stipe, but that doesn't seem to be the case. Stipe is also long and central to the cap. Probably the closest I can get is an Amanita species? You can see how the gills of the smaller specimen have darkened since I first spotted it. Broad caps have also discoloured slightly since my first sighting (yellowish tinge), and margins have become wavy as the caps have distorted. Large gills serrated but free. Veil remnant seen in 4th photo. *PS: Saproamanita genus was created in 2016 for saprophytic Amanitas.

Habitat:

Spotted in native bushland along Devlins Creek, in northwest Sydney. These specimens were growing amongst leaf litter and grass beneath eucalyptus trees. Blackbutts, Sydney turpentines, and large red gum and blue gums overshadow the area. Well-saturated after frequent rains these past few weeks, and well-shaded area. Fungus is flourishing.

Notes:

05 June, 2019 - ID possibilities. I was already leaning towards the Amanita genus from photo comparisons online, but just couldn't seem to narrow it down. However, a member of the Australia & New Zealand Fungus Identification Group (on Facebook) suggested A. foetidissima or A. nauseosa as ID potentials. Both species look very promising. TBA.
