...anyone ever eat Beefstakes?? And I have never got sick.....
This is the information I found on Beefsteak Morel mushrooms. This information comes from 2 different sources, Morels of the UP from exploringthenorth.com, and from Morel mushroom Identification page at michiganmorels.com.
******************************************
Potentially dangerous beefsteak morel. Has an irregularly lobed and wavy, reddish brown cap and a yellowish white (often pinkish white) stem. It is not hollow, though there may be air pockets within the flesh. As the mushroom gets older, the ridges and lobes darken to nearly black.
The poison in false morels is MMH, or monmethylhydrazine (a chemical also found in rocket fuel). Its toxicity may be cumulative (you may eat false morels safely for years and then, one day, croak after one bite). Clearly, MMH is not to be messed with.
Of all the morels and lorchels that occur in Michigan, the beefsteak morel has about the longest fruiting time on record, from early April into June. It occurs in a variety of habitats primarily on sandy soil and under pines and aspens; however, it has been found under hardwoods and in open sunny areas as well. This species apparently does not occur in the southern portion of the Lower Peninsula, but it is abundant in the Upper Peninsula. Fruiting bodies of this species, under certain conditions, yield the same compound as is used in some rocket fuels. It will not put you in orbit, but it might put you "out". There is more controversy about the edibility of this species than any other wild mushroom in Michigan.
Many people consume beefsteak morels, gyromitra esculenta, without developing noticeable symptoms of hydrazine poisoning. As a result, people think these are perfectly safe to eat and pass them around to their friends or sell them with no warnings. They are not a safe species to consume in quantity, no matter how they are prepared. Of the recorded poisonings by the beefsteak morel, 14% were fatal.

The "Beefsteak" morel is one of the "false" morels and can make you sick or be potentially fatal if eaten.
