What are the symptoms of black mold and what does it look like?

My house tested positive for white mold in the HVAC system, How toxic is it and how to determine the species?

• I have lived in this house for over a year now and have been feeling more symptoms as time goes on; slightly upset stomach, major fatigue, short term memory problems, blurred vision, easily irritable, trouble concentrating, mild head aches, some sneezing, very nervous and probably more that is all I can remember at the moment. I have gone to the doctor many times over the last year with the previous symptoms, they can't seem to find an answer. I am feeling like I am going crazy , here and people have said the same. It's not a joke, I feel like sh#t. I bought a home test kit for mold, taped it to my ceiling duct, 3 days later white fuzzy mold was growing. I went in to the attic to look for mold, I didn't know what the heck I was looking for might have saw mold and didn't know it, there was some areas that looked white but I didn't look any further. I then removed the vet cover from one of the vents and saw small specks of a white fuzzy substance, I couldn't get close enough to really compare it to the positive sample in the test kit. From mi experience work in construction and doing actually duct removal I have never seen anything like it in my 50 years of construction work, I know ducts do contain dust generally it is always yellowish to brownish in color, never white. I need some real help from someone who fully understands the issue...
