No specimen available

These are the large thick fleshed apple orchard morels that I call “esculenta.” Recently it has come to light that some of the old apple orchards here in eastern NA are contaminated with lead/arsenic, as a result of the former practice of using lead arsenate as a pesticide. Although it is non trivial to test soil for arsenic content, it is easy to test for lead. Last year I tested several of my favorite orchards here in NE PA for lead, and all results were negative (no significant lead content). So I figure my orchard morels are safe to eat… based upon the pesticide based premise “there is lead if and only if there is arsenic.”

This year’s yellows/grays are very early, as a result of a heat wave during the first week of April. I also find a few of these esculenta types in Tulip Poplar/White Ash forests where the smaller “deliciosas” are much more common.

So, is the morel…

that “grows in California” only the type that grows in apple orchards? Has there been some DNA/habitat correlation? Is the type that grows under dead elm also the one that grows in California?

Why the attack upon “esculentoides?” Surely there is at very least some sort of debate here.

Thanks for the compliment, Maxwell! Whatever these are, they sure are photogenic!

Down here in Australia I’ve seen termites make similar constructions in timber but I marvel at the ability of nature to create something like that without help. I like the photos too !
