Proposed Names

61% (2)
Recognized by sight: We need a name for the Ameican M. procera
55% (1)
Recognized by sight: there is more than one “procera” on the east coast; there are no good latin names yet for North American material. Prob. all of the procera group are edible, tho. If you have been eating your local “procera” all along, a new name won’t change things for ya. The only large, economy sized, toxic “lepiota” or parasol mushroom species that you need to be concerned with is Chlorophyllum molybdites, distinguished by its green spores.

Macrolepiota edibility

as far as i know, Macrolepiota species are edible. However, they are good at taking up heavy metals, they may grow in orchards and such – places where toxic chemicals are routinely used. In other words, use good judgment, and not the hunter’s instinct.
Chlorophyllum species: some are edible, some cause a lot of gi distress, and this depends on the species and on the person consuming the mushrooms.

However, in this case, where the species is not known, documenting them for science seems really important!

Ok- so this would be considered one of the edible species of Macrolepiota, correct?

in the Macrolepiota procera GROUP, certainly not a Chlorophyllum

one character that makes this is a Macrolepiota, and not a Chlorophyllum is the covering of the stipe – look at the pictures and see that there is a fine spotted/tigerstripy covering over the stipe – this is typical for Macrolepiota, and Chlorophyllums lack this.
Debbie is correct that the species Macrolepiota procera is restricted to Europe; related species that look similar are present in the USA, but nobody has named them yet.

Are you pretty certain that this is procera? Thanks
