Stem 6 cm long, 2 cm diameter at base, tapering slightly towards top, with large descending white ring. Stem smooth above ring, fibrous below with some tawny discolouration at base.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Spore print

The Prince, A. augustus has a purple-brown spore print. I am also interested in the dark brown centres cf. A. moelleri. Regards

This looks a possibility. One

This looks a possibility. One of the poisonous species so not one to mix up with A augustus.

Thanks Malcolm, I'll have

Thanks Malcolm, I'll have another look at A. moelleri... and if I find myself in Felxistowe in the next few days, I'll have another look and hopefully get a bit more data, eg on the spores...

I don't recall a bitter

I don't recall a bitter almonds smell. The spore print was dark brown but unfortunately it was mixed with mushroom juice and by the time I got round to looking for spores all that was left was a mass of black light spongy material and a couple of fly pupae... I agree that the centre is very dark for A, augustus but can't find a suitable alternative. A moelleri has very tight small scales, is usually smaller than the larger of my specimens and according to Roger Phillips at least is usually found in the summer...

A mystery for the end of the year!

This looks interesting but I'm afraid I've never seen anything similar so can't help. Hopefully someone expert will suggest an ID.
Anyway it gives me the opportunity to wish you a very happy New Year and all the best finds for 2012!

A good omen!

Thanks Janet... and a happy productive New Year to you too! I'll put the mushroom on MushroomObserver and see if anyone comments there... I must tell you about the weirdest thing that greeted me this morning... There was a swan in our back garden! The garden is only about 10 metres x 8 metres, with a fence round, so the magnificent bird couldn't get off the ground... not that it was trying much, enjoying the small pond and the occasional wander round - including tapping on the conservatory where we were sitting with its beak! In the end we shepherded it down the alley at the side of the house, up the road and back into the park. When it saw its friend on the pond it ran, took off and glided down to it. My daughter shed a tear to see it safely back where it belongs! I got some nice pics and will post them here in due course... a good omen for 2012, I believe!

How wonderful!

What a strange visitor, not quite the usual first footer! I look forward to the photos. A lovely end to the story with its safe return to the park, I wonder what made it land in your garden and whether it will ever make the same mistake again? Definitely a special omen!
