Recognized by sight: like Alan said: cap texture, veil structure, gill spacing, um… gestalt stuff. Probably something more like Clarkeinda sp or in that clade of pigmented-spored Agaricaceae

dark gills for Chlorophyllum. don’t know Clarkendia well enough to debate.

Chlorophyllum/Clarkeinda species.

Agree with Christian here.

were only observed in the stage shown in the photos, and, to the best of my memory, no green tints were present (some red spots are visible, though they look more like stains/bruising than “tints”). i can check to see if there’s material when I get back to La Paz. if there is, microscopy will be forthcoming in the next month or two.

Some strange Melanophyllum perhaps?

where the gills even a little bit green?
it does look more like Agaricus, IMHO

looking forward to you findings Danny :D

slaving over a hot scope syndrome!

there exists the possibility that late spring/summer 2012 will be spent scoping a good many of these bolivian observations, as well as whatever we collect during the next three months, which may finally lay to rest the dozens of “Indet.” entries in the herbarium. The Evans collections are (almost) all here, and though many are still in perfectly good shape, most only contain a single fruiting body.

note to self: factor greater amounts of bourbon, vitamin D supplements and optometry/chiropractic appts. into projected summer expenses.

Agaricus, si!

Clarkeinda, no.

IF has put most of the Clarkeinda back into Agaricus. The spore drop (as opposed to gill stains) that I can see on the annulus looks pretty choco brown to me, so no, IMO, it’s not the Strophariacea Clarkeinda by Kuntze.

Pileus texture

The pileus texture, free gill attachment, membranous partial veil and bulbous stipe base strongly suggests Agaricus and argues against Strophariaceae. In addition there appear to be chocolate brown spores on the annulus. Gill color argues against.

i ought to upload these more slowly, since so many are without any input and they seem to attract attention when bumped.

The colour of the gills doesn’t look right for Agaricus, it is too grey. I think it is something in Strophariaceae; perhaps Stropharia, in fact… Not sure. Interesting one.

doesn’t really look like this has produced chocolate brown spores.
