mold colony photos

While it would be nice to be able to identify molds by macroscopic photos,
if you are in the industrial hygiene sector, this kind if identification
is highly uncertain.  You can be easily fooled by the appearance of a mold
colony on agar, depending on the type of medium used, growth conditions, etc.

Some molds look identical on growth medium, but at microscopic inspection
will reveal they are in different genera, or even in different families.

I have high concerns that the use of any method that doesn't include a
complete microscopic inspection will lead to misdiagnosis of a problem.

Our compan has had to help people out of jams who have done just that!!
