Agaricus Campestris [field or meadow mushroom]


Since the foray Wednesday, all I could think about was getting out again. My mushroom hunting in the past was usually in a very specific spot, for a very specific kind. More of a waiting game. Wednesday’s foray was more ‘dive in and see what you find’ – which is far more exciting.  So after a few days of generally deciding to temper my enthusiasm and wait until next week’s guided foray with the Alberta Mycological Society, I caved and figured I’d just get

    I love that in mycological circles there is room for such specific debate issues as the decision to snap off or cut mushrooms. Such care for the subtle preferences of these mysterious things, even if irresolutely.

  2. Can’t wait to hear what you find out – and I hope it is soon enough to eat them, if they are edible!

    You’ve stumbled across a great cache of my favourite local edible, Agaricus campestris (field mushroom). It’s basically the wild equivalent of the cultivated button mushroom. Damned tasty too.

    Here’s the full details:

    All this rain has mean an extended cropping season, and since they prefer fields (such as schoolyards and parks) Edmonton grows a lot of them. Enjoy! If you see any Boletes let a girl know, k?

    Jasmine – THANK YOU. I was confident on the Agaricus [no volva suggesting Amanita], and no yellow staining so not Xanthodermus, but still am pretty green at this, so have been cautious with my assessment. Campestris was my top contender for an ID guess [gills too brown, not pinky enough for Arvensis], so I’m very glad to hear you agree. And yes, if I locate some more boletes, I’ll be in touch – if for no other reason than as a ‘thank you’ for weighing in here!

    Here’s most of my notes:
    partial veil, stuck to stem
    white top, with some yellow on mature specimens, turning to brown
    starts with wide convex, flattens with maturity
    gills are white young, brown maturity
    spore print is med brown
    very bulby young specimens, with partial veil closed
    didn’t seem to take long to get to browny/pinky/purply gill color stage
    light shagginesss at base of stem
    one specimen had fused stem bases
    mature cap diameter of 4-6″ maybe
    young ones look like big button mushrooms from the store, with a more round, bulgy top
    they were growing in mowed grass along the edge of the unmowed riverbank
    stems are long, perhaps to get them out of grass, 4″+, and sturdy med thick
    smell is very pleasant, classic ‘mushroom’ aroma
    not presence of yellow staining at base of stem when cut [agaricus xanthodermus ruled out]
    didn’t notice a circle ‘fairy ring’ pattern, more of a here and there pattern perhaps
    Harvested 24-30, but there were likely 40-50 in that one spot

    The younger specimens above look a lot like Aminata’s (aka Death Angels) around here. White shrooms with white veil and white spore print = STAY AWAY!!! hehe

  7. Kevin says:

    Barry – great point, that having a variety of maturities is important to be able to do a confident ID. Also worth knowing how to ID an Amanita, and any other lookalikes that may exist in your area!

    Glad I could help. Speaking of wqhich, I went wandering through the University area on my lunch yesterday and had to return early, my bag of ‘shrooms was getting to heavy to carry comfortably. I’d guesstimate 12-15lbs within six square blocks of my office. If you ever need ‘shrooms, come visit (the Uni doesn’t use pesticides on any of their properties, organic-ish mushrooms for free, score!)

  9. Kevin says:

    Jasmine – wow. Good to know. Ever need…hah…I’m stocking up for the winter.

  10. The Cheesiry says:

    I will have togo out to our coulee to look for shrooms. THe fairy rings are finally growing but we usually get edibles growing in the yard…nothing yet though!
