Mushrooms are a tricky one - while they're not considered to be animals (despite scientific evidence that they share much more in common with animals than they do with plants), they're notoriously difficult to check for tiny insects that may hide among the gills or in the fleshy part of the mushroom - and insects (with the exception of one type of locust) are most definitely kosher. Therefore, mushrooms must be very carefully and painstakingly examined prior to consumption, and many Jews prefer to avoid them just in case even though they're kosher (the same is true of celery and a variety of vegetables).
