Observation 195488: Agaricus L.
When: 2015-01-04

Notes: Small group of fungi at base of a line of Lilly-Pilly trees. Varying stages of maturity displayed. Fungi seemed to be attached to fine root system possibly belonging to the Lilly-Pilly trees. Attempted to get a spore print without luck .
I will update the notes if successful. Only the one group found in the grassy area although there were other (different fungi), fruiting. May belong to the pholiota group.

OK I was going to do all 4 x Magnifications but when doing the 100X’s I thought this was a good starting point. The spore shown are reasonably sharp and clear, and in good numbers. The section for the micrograph was taken from a fresh mature part of the Gill(dark) and the Cap using KOH soluti...

Agaricus augustus

Suggested by Skye Moore. with reasonable assurance on pileus cap features.

link for Chlorophyllum molybdites

I have attempted to contact the author, Skye More unsuccessfully to this point in time, and have taken the liberty of posting her paper on local common fungi close to my region. Page 26 is the most relevant pertaining to this obs. comments welcome please. kk

Micrograph added.

Please see notes with image.

Hi Richard. I did look at the key and it sort of looks right but did you look at

Resources » Garden Fungi » Garden Fungi – What is that fungus in my garden? » Garden Fungi – Chlorophyllum molybdites This also has similar features in the key , Except the spore print in my find. I was unable to get a spore print and left it overnight. The gills turned dark brown and the spore print was a light chocolate colour. In the Queensland sheet key for
Resources » Garden Fungi » Garden Fungi – Chlorophyllum molybditesthey state that the spore print is light green? What I can say is the Fungi appeared in a grassy area near a line of Lilly-Pilly after rain. I really need to do some scope work to try and get some more answers. Thanks for you time, patience and input. I will keep you updated.

“cogwheel”

i think the term more aptly applies to species like Agaricus arvensis…
A. augustus isn’t “described” as having a “cogwheel veil” but, i use it to refer to the texture…of the veil.
i just want wanted to make that clear.
i have never seen A. augustus in real life, so i have no idea if the actual “cogwheel” pattern is present before the species starts to mature.
i’m just not sure how to describe that texture, so that is what i say.

Agree thanks. Another lesson learnt. I checked one of the specimens in the drier and it shows the "Cogwheel effect " clearly. Yay!

you might be my favorite person on MO…

this is definitely an Agaricus.
google, “cogwheel veil.”

oh and, bloodworm died. he got hit by a bus while crossing the street in attempts to pay a transsexual hooker the money he owed her.
it was tragic.
but, he left me all of his collections.
so, at least something good came of it.

btw, ill be scoping all of the Gymnopilus you sent him shortly…
and doing DNA work.

Fungi did not have any distinguishing smell, except to smell like the normal eating mushroom. Did you notice the texture in the veil. It seemed really different to what I am used to seeing. I am going to try and do a full range magnification test micrograph and see if the results give anything away. Time is my ruler unfortunately.( I should have been born a twin!!, but then we still probably wouldn’t agree,…….. hoha. ) Richard by the way I noticed you have dropped the Bloodworm signature now for sometime?? kk

Agaricus augustus.

what did they smell like?

Agaricus subrutilescens…

but, i don’t know if that occurs where you are.

Naming suggestion

I have a local environment and common fungi data publication that seems to be close to the observation. Two things I have noticed. The gills change colour slowly after removal from their habitat. Specimens with some root and soil attached and with partial veil in place, have retained their white colour but will probably turn dark brown also in my opinion. The Gills were not tinted Green as is documented in the source paper . This may only be a local environment situation. List of Species: http://mushroomobserver.org/name/index_name/149138?q=2SeDa

Spore Print

Overnight The fresh Cap gills changed colour from white to Dark Brown. Spore colour was Light Chocolate Brown. I have some reservations regarding the Spore Print colour from the Gill colour change as this might be attributed to the deterioration of the pileus and not a true spore colour print. The print obtained was not a 360degree print but about 275 degrees and with a smudged general appearance..I will dry the specimen.
