Observation 8032: Strobilomyces Berk.

I thought this one would be an easy one for Rod to give an opinion on. I feel that it is an Amanita and would stick my neck out and suggest it might be an Amanita costaricensis. (foolish lad!) Location was Comboyne State Forest.I do apologise that one of the images is not sharp, and also I had real trouble getting the white balance correct. Hence the two images. (when purple or a variance of purple is in an image the colour reproduction even with the best ICC’s still gives some variances. I think that there is not enough incorrect colour bias to allow hopefully a correct identification.

Wrong specimen loaded.

Thanks to DV, I have been kindly advised, I loaded the Wrong Microscopic Images. I Pulled the dried specimen from the Wrong Draw!.(How Dumb). I have removed the incorrect images and will reload the Right ones (hopefully) as soon as as can. This specimen has a history of my mistakes.(omg)

good that you are using your new scope, but what you show is not a Strobilomyces spore.

Strobilomyces spores are elliptical and ornamented. Not sure what you are showing here.

Check out Kuo’s webpage on Strobilomyces, where he shows the spores:


But don’t give up! It takes time to be able to do the micro and get the results that you want! I am still struggling, meself! :)

The macro certainly resembles Strobilomyces, but…wish we could see that hymenial surface, too.

Images updated

Three microscopic images of Strobilomyces using Mezlers’ reagent.

Pores v Gills

I went through my notes from this find and found that indeed I had written down at the bottom of the page Under cap Pores. My apologies to the error in the notes originally provided. I have also found a number of the same specimen this year which forced me to re-read my original notes. Thanks to DS and DV for their polite notations.

Pouzarella nodospora resembles this, and has gills.

Gave it both names

Here, I gave it both names, so it will show up in both listing of genus species as a possible.

I had the same first reaction as Debbie did…

My first thought was the same as Debbie’s. Did it have pores. It sure gives a strong sense of Strobilomyces. If it had gills, then, … There are [at least] 3 problems with A. costaricensis as a possibility…they are well known to real estate agents: location, location, location. Amanita costaricensis is known from Central America and is very likely to be endemic in that region. Amanita costaricensis is closely related to A. onusta of North America, and both belong in Bas’ stirps Microlepis. No species of this stirps has ever been reported from Australia. Australian species of section Lepidella (so far as one can tell from the literature) belong to a relatively small number of Bas’ stirpes (plural of stirps). The warts seem more pulverulent than “fibrous”. I’ve been snakebit enough lately. I’m not going any farther.

So there is an opinion. I don’t think it is very much help in terms of an eventual determination however.

Very best,



I seem to remember xxxx (Pores). If it had pores I think I would have remembered for sure. Not a definite reply I know.

Gills or pores?

If it had pores, I’d say it was a Strobilomyces, or something like that…are you sure that it had gills?
