PORTLAND, Maine (AP) - The tropical storms that drenched the Northeast this year left an unexpected bounty: Thousands of mushrooms have sprung up on some lawns, and foragers have filled bags with wild ones plucked from the earth, stumps and logs.
"It was like a scene from 'Alice and Wonderland,"' said David Fischer, who wrote "Edible Wild Mushrooms of North America."
The mushrooms are providing good meals for people like Margaret Primack of Newton, Mass., who collected 60 to 70 pounds this summer. But because some mushrooms are poisonous, they also present a danger for people who can't tell the difference between the tasty and the toxic.
The Northern New England Poison Center has seen an increase in mushroom poisoning cases in Maine, New Hampshire and Vermont, with 97 in August and September, nearly double the figure from the same time last year.
"People need to have respect for mushrooms," said Karen Simone, the poison center's director. "They don't understand that this can be dangerous."
Mushrooms varieties can look similar, and it takes a trained eye to tell the difference between those that are safe and those that are deadly. Mushroom and health experts discourage people from eating wild mushrooms unless they're absolutely sure they're safe.
"If somebody eats the wrong thing, they could be dead, and it's not a fun way to go," said Fischer, who also runs a website dedicated to wild mushrooms from his home in Syracuse, N.Y.
Consumers who are worried about safety can buy mushrooms from the nation's commercial growers, who produce the white button mushrooms commonly used on salads and pizzas, along with shiitake, Portobello and oyster mushrooms.
Commercial mushroom production also is up, topping $1 billion for the first time in the 2010-11 growing season, according to the U.S. Department of Agriculture. That's an 8 percent increase from the previous year. Pennsylvania is the leading mushroom state, producing more than half of the nation's commercial crop.
Mushrooms thrive in wet weather and there's been no shortage in the Northeast. Most of the region had more rain than usual in August and September, with cities like Baltimore, New York and Philadelphia setting two-month records. Almost 30 inches of rain were recorded in New York's Central Park during that time.
The downpour didn't help spring mushrooms like morels, but it boosted other varieties like black trumpets, chanterelles and hen-of-the-woods, which can weigh 20 to 30 pounds each. Hundreds of common mushrooms, and sometimes more, appeared on lawns and golf courses.
