Here's a site focused on Florida:
But it's probable that other states' county extension services will also provide mushroom identification and/or refer residents to experts in the field.
Northern California can *reliably* count on three or four families each year, primarily during January through March, being taken to an emergency room due to mushroom poisoning.
It's generally a grandparent/grandchild combination due to local mushrooms resembling those the older person knew in another country *or* another part of this country. Wanted to take the kid(s) out for a nice day and... It's really sad and totally preventable. And we're not
talking about toddlers. These are usually kids from about 6 y.o. to maybe 16 y.o.? The ages that grandparents *want* to take out for a day in the countryside.
I hope you get a firm identification on these fungi maybe as soon as tomorrow morning!
