Agaricus sp.
Agaricus is a genus of mushrooms containing both edible and poisonous species, with possibly over 300 members worldwide. The genus includes the common ("button") mushroom (Agaricus bisporus) and the field mushroom (Agaricus campestris), the dominant cultivated mushrooms of the West. Members of Agaricus are characterized by having a fleshy cap or pileus, from the underside of which grow a number of radiating plates or gills on which are produced the naked spores. They are distinguished from other members of their family, Agaricaceae, by their chocolate-brown spores. Members of Agaricus also have a stem or stipe, which elevates it above the object on which the mushroom grows, or substrate, and a partial veil, which protects the developing gills and later forms a ring or annulus on the stalk.
thanks RandyL. Think I have several different photos of this same species. I'll post them later...
Yes I believe both these observations are the same species of Agaricus, not sure which though. I will try and key it out but I'm not too sure which species grow in Japan.
Randy and Orbea, I added a photo of the top. Not 100% sure though. My hard drive crashed and in restoring the photos, they all got different numbers and the same date! This one was the next in sequence, and the setting looks the same or similar, so it's probably OK, as I always take photos of the top as well.
Do you have any images from the top? They sure look like they could be the same, pretty Agaricus!
Randy, Is this the same species before the veil breaks? http://www.projectnoah.org/spottings/151...
I thought I did Randy, but they weren't in Aperture. I will check the hard drive when I get time. Maybe they didn't come out, or hopefully I just overlooked them..
Beautiful spotting! A time lapse of that veil breaking would be awesome to see.
Did you happen to get any pictures of the top?
