Observation 7849: Amanita Pers.
When: 2007-03-15
No herbarium specimen

Notes: I am not sure about this group of Fungi but think they are Rhodocollybia butyracea. The photo has been white balanced and was taken in natural light. The reference I used shows the cap varies from pale brown to chestnut brown. I think the colour of the cap is in line with this statement. The reference also states that there can be a large variation in the cap colour.

Amanita sp.

Information re digup noted. I forgot to answer a question about removing specimens in OZ. Generally the inclination and teaching on native vegatation (flora)is “do not remove.” In fact in Reserves and National parks it is strictly not allowed. I realise that this really complicates ID. (Especially orchards, this is really frowned on.) I will have to change my ways with the Fungi ID. Most of the fungi I photograph is in remote areas except for the images I take on my property. Travelling to a site with the equipment that I use restricts me somewhat, but the info for ID will be put to use. I do have a good ongoing relationship with all the Wildlife Rangers here. Many thanks and hope to make life easier in the future.

Debbie’s comments…

I agree with Debbie and Douglas.

I would add that, in Australia (as in the Pacific NW of the US, east Asia, New Zealand, etc.) there are taxa that have the appearance of a species of section Vaginatae…until one looks at the bottom of the stem and…OOOOPS…there is a bulb, maybe little, but a bulb. In Australia, there is a species called A. subvaginata, which seems from the description to be very like A. farinosa (in the US there are two things under this name; the name is also used in E Asia), A. nehuta (New Zealand), etc. On several continental remains of Gondwana (at least South America, Africa, probably India, etc.), there are also bright colored relatives of the same group. Enough said.
These “false” vaginatae, however, do have a cap character that often is present, and is very helpful. Light to moderate rain doesn’t wash the volva away very easily because, the skin of the cap doesn’t gelatinize very quickly (or at all?). The volva is actually bound to the cap by hyhpae that pass undamaged between the volva and the cap’s skin (pileipellis).

The whole topic of the various ways in which an Amanita cap can separate from the adjacent volva is quite a fascinating one (well, anyway, I like it).

Very best,

Doug is probably correct. This little grisette should also have a long, membranous volval sac, buried under the ground. Grayish color, lack of a partial veil or skirt, striations at the cap edge, and white, free gills make it an amanita, and one from section vaginata.

Look alikes (if they occur in your part of the world) would be Xerula sp.(Oudemansiella in older literature) with looooooong rooting stipes, no veil or volva, and white, more widely spaced, attached gills.
