Observation 14917: Amanita vaginata group
When: 2008-12-03
No herbarium specimen

Notes: This fungi only had the cap showing, and then almost hidden amongst the forest floor leaf litter. I lightly brushed the leaves away and was surprised at the thickness of the stem in comparison to the cap. I continued to clear away the debris till I reached an area where the stem was at ground level. I carefully attempted to remove the fungi without damaging it, but in doing so, some of the body that was below the surface began to fall away from the main stem. This layer seemed to be another layer around the stem that was separating from the stem. The cap was sticky and the stem was moist and sticky. There was no aroma present that could be distinguished.
At first I thought it was a Leucoagaricus rubrotinctus, but there was no annulus ring, (unless the growth at the bottom of the stem), was part of the annulus. I removed the cap and cut it in half. The cap was gilled and also moist. The area that the photo shows is not the natural habitat. I placed the fungi on an area about a foot above where I found the specimen. I attempted to get a spore description but the results were not easily defined. The spore appeared to be off white or a milky colour, but the cap was so wet it was dificult to tell. I looked for other specimens in the surrounding area but could not find another example. I think what surprised me most was the size of the stem on an inmature specimen in comparison to the cap.

Amanita vaginata

Rod, 11993 definately seems to be very much the same.

Amanita vaginata group

Much appreciated. Thanks to Rod Tulloss

Amanita sect. Vaginatae in Australia

Relatively few names have been created for species of Amanita sect. Vaginatae endemic to Australia. I know of six such names:

A. albovolvata A. E. Wood A. pallidobrunnea A. E. Wood A. pallidochracea A. E. Wood A. pallidofumosa A. E. Wood A. punctata (Chel. & Cheel) D. A. Reid A. sordidobubalina A. E. Wood

Synopses for all these species are on the Amanita Studies website. Most of the original descriptions are not very helpful at the detail level; however, cap colors may help in the case of so few candidates. The only one of these species that I know from personal experience is A. punctata. I have examined material of its type and other reliable material. Most descriptions of A. punctata in books are wrong. There must be a similar taxon in Australia and (perhaps) another in east Asia with smaller spores.
