 [ Symptoms ] if mold is a microscopic fungi does that mean a person allergic to mold might be allergic or sensative to mushrooms [ Disease ] you ask a very interesting question and i can see where you are coming from after all mold is a fungus and mushrooms are fungi so if a person is allergic to one type of fungus would not they be allergic to all fungi fortunately the answer is no  or at least not necessarily  when we talk about a mold allergy  we are usually talking about a nasal allergy also called an inhaled allergy that means when we breathe in mold spores our immune system treats them like an invader and mounts a hyperactive attack to get rid of them that hyperactive attack leads to the common symptoms of nasal allergies sneezing runny nose swollen nasal passages and more however most people do not inhale mushrooms most people eat them when you eat something your stomach acid starts breaking it down quite quickly while it is possible to have a true food allergy peanuts is a particularly lethal example most of the time the immune system does not view food as an invader even if you had a nasal allergy to mold and then you ate mold you likely would not have an allergic reaction to it you might get good and sick from eating mold but that would not be due to a hyperactive immune response in your nasal passages it is a good thing that one type of allergy does not always translate to being allergic across the board for example most people who are allergic to penicillin can still safely consume blue cheese    which is created by injecting cheese cultures with penicillium it would be a shame if everyone who was allergic to penicillin was denied the creamy luxury of a good blue cheese wishing you well
