Observation 7732: Entoloma virescens (Sacc.) E. Horak
When: 2008-06-08
No herbarium specimen

Notes: This fungi was photographed at Swans Crossing Forestry reserve. The fungi stands about 70mm in height and is a mature specimen. Aging causes loss of blue colour saturation, and dark spots appear around the edges of the cap and outermost gills. I have not been able to find a record of ths fungi in my Australian references, but Clive shirley has a specimen on his excellent website. It appears to be free from insect attack as far as I have noticed.
I have photographed several of these over a period of time, and have noticed that the stem has slowly rotating grooves extending up from the base to the top of the stipe where it meets the cap. I will go through my records for previous images and post them when I locate an image that is worth showing. Clive also agrees with me about the loss of saturation in the fungi with age. I have only found this fungi in single appearances, where Clive has seen them in groups. This may be native to Australia.

I have noticed that this specimen is usually found in April (in Australia) and that quite often there is an accompanying less mature specimen close at hand.

Thanks Clive,
E. virescens also occurs in Japan; at least what they are calling virescens…

Hi Noah,
As far as I am aware E. hochstetteri is a New Zealand species only were E. virescens is Australian. The two species have a slight difference in cap shape were E. virescens has a small umbo were NZ E. hochstetteri does not or is very slight you can see this in the images on my website.

The green one

I want to see is Amanita austroviridis which is a amanita with dark forest green gills and a pale green cap.

On the Fungimap website it says “Entoloma virescens (Berk. &M.A. Curtis) Courtec. Mycotaxon 27: 131 (1986) [=Entoloma hochstetteri (Reichardt) G. Stev. Kew Bull 16: 233 (1962)]” other things I’ve seen are saying they are different species.
Should we be calling this E. virescens? Does E. hochstetteri occur in AU or is it a NZ species?

I don’t think

that this has any taxonomical significance (scollop edge), it just seems to be a modification or incidental growth. But I’m astonished about them not turning green. It was very evident in my collections. They did not change their exterior blue but the context greened when cut or bruised…
As to green species there is this Hygrocybe pseudograminicolor which I found at Daintree NP … ever seen it? Amazing mushroom!

Entoloma hochstetteri

Gerhard, I have never observed these to go green in the areas I frequent. Mainly when they bruise or age, they become lighter in colour, and develop dark spots. One of my main ambitions is to photograph a true Green specimen of any Fungi.
Did you notice the scollop edges in image 34200. I do not see this in every specimen.

The light blue ones

are more common, yes, and they are native to Australia … I’ve never seen the dark ones. The name for them would be E.virescens then I guess … did you mention that them all turn to green when aged or bruised?

Colour variation

There seems to be two distinctive colour variations in the specimens I see. They are mainly the lighter blue colour and the darker more saturated blue specimens are not as common.

them are separate species. I found this one, it is called Entoloma hochstetteri. There is this E.virescens, too. According to the specialist in this genus, Mr. Noordeloos from the Netherlands, and our president, Mr. Hausknecht, these are two species but I can’t tell the difference though … I just found this one during my stay… and one tentatively called E.haastii. Pictures will follow somewhen…

Entoloma hochstetteri

Debbie, thanks for the welcome back. Always watching the site even when not participating or active. I have never been able to get a ruling on these. One side calls them one name, and another gives them the other. I cant really see any difference! I am too inexperienced to make that decision. Chow, kk

which one is the current name?

Entoloma hochstetteri Image taken 22 03 2009

After heavy rains again managed to get into Swans crossing. This was a single specimen once again. The fungi was in reasonable condition even though we had more than average rainfall. (7 inches in 48 hours, I believe what is termed here as once in a “hundred years rainfall.” Only trouble is we experienced almost this much only five weeks prior.)

Nice photo! I’ve added it to the Wikipedia article at http://en.wikipedia.org/wiki/Entoloma_hochstetteri

Added image

It was rather surprising to find this specimen so early in our fungi season. I have added it to show that the colours vary considerably from specimen to specimen.

the bright blues in that featured photograph are amazing.

Blue Fungi

I have just come across a reference to Entoloma sp. that has me wondering if in Australia there are two species. The reference I have names the lighter blue one Entoloma virescens. I am not sure if this is an update in naming or a separate species??? Entoloma hochstetteri V virescens. (Ref. Fungi Downunder Australia Pat & Ed Grey FungiMap)

Photographed at Swans Crossing upper on 26/12/2002

This was taken during severe drought in our region and in our summer. The colours were effected by both age and extreme weather.

What a spectacular color…
