European names

For similar N. American mushrooms are being trashed rapidly. For example it appears that many chanterelles such as Cantharellus cibarius does not occur in North America. Sad but true for the amateur mycologists using available books.
Always remember that what has been said about N. American mushrooms such as the parasol (which gets my vote as a standardized common name for the complex)still holds true. The mushroom has not changed. Just our way of naming it.

I agree with Noah that your photo made me think of Chlorophyllum molybdites. Spore print these before deciding to eat.

read this…

it would be helpful if you dried then and sent them to Else Vellinga, them we will get names for our North American Macrolepiota

The growth habit of these reminds me more of Chlorophyllum molybdites…..

Another as if

Ok, so please help me learn why you guys think this. The species prominens obviously resembles very closely procera. So please help me understand what features make you guys so sure.


Only Europe?

Are you saying it appears that Macrolepiota prominens/procera and or Lepiota procera only occur in Europe?
Please forgive me if I have misunderstood your statement.
All sources I have found state that these species are native to both Europe and North America. The only source that I have found that describes the range of prominens simply states its been found in Quebec.

Along with so many other names we have been using appears to be a European entity….

These were very large

All the photos I have found show that Macrolepiota prominens does look very very similar to L. procera. The mushrooms pictured are fairly large. From what I have seen in photos and have read on-line they are larger than the typical prominens.

If you have a better source of information please clarify for me because this is still a learning process for me.
