Hi Brenda, it showed up last June and I"m not deathly ill either! Dr McShane told me that it was her job to worry, not mine and she wasn't worried about it. However, she did have me undergo a bronchoscopy with biopsies of a suspicious area but they didn't find it. They did find asperigullis (sp) but it didn't grow. A fungus shows up in my samples but never mucor again. She told me that it is very common to have some fungus.
