Anyone performing work or performing an inspection who is not a certified mycologist should absolutely refrain from identifying fungi! This prevents incorrect assessments and possible scares based on an incorrect identification. I’ve been performing inspections for 19 years now and have seen water damage with inorganic particulates that mimicked fungal growth in pattern and structure with lab results indicating no fungal spores present. In addition to causing fear this can cause other problems including law suits and trust me, you don’t want to be in the seat getting roasted because you incorrectly (and not qualified) commented. Please use the term “possible” or suspect when commenting on suspected fungal growth and save a major headache.
