Re: QUESTION FOR CARL GRIMES

[Guest guest]

Someone trained in identifying mold might make a good guess on

some of them, if they appear as a well formed colony in the

environment like they do on a culture plate. But that rarely

happens. It needs to be viewed under a microscope to see the

shape and color of the spores and the growth structures to make

a positive identification.

For example, even under the microscope spores from Aspergillus

and Penicillium are indistinguishable. If part of the colony is

present then the spore reproduction structures looks like a broom

for one and a string for the other.

Why do you need to know the type of mold? Removal is the

same for all but sometimes there are medical reasons for

identification.

If you had pictures of different colors of molds, viedo and pictures, would

you or anyone be able to dturmine the type of mold it is?

what if you knew the season/month of when the pictures were taken?

like if it was a large spot of just one color/mold.

tooken in spring.

Thanks Carl, mostly just wondering. are there certain types of mold that have a

unmistakable color to them? like maybe some green molds?

Carl, if I recall right, this color of green mold closely matched that of

trichaderma<spelling, been alwhile sence I looked for pictures,seems there were

some pretty good sites but cant seem to locate them now.

just wondering if theres many other molds that would match that same

light,bright green, cant seem to find any when it comes to indoor mold

growths, so just wondering if it would be a color that might not be shared by

many other mold types. wouldn't it be great if we could tell the type from

solely the color. but ofcorse nothing about this can be easy.

Lots of them can be green or partly green. Penicillium,

Aspergillus, Trichoderma and many others. Stachybotrys is actually

a greenish-black, for example. Consistent colors occur more so in

the lab than in the environment and during different stages of its

life cycle. Myself and others have seen white Stachybotrys (as

identified by a lab).

What you could do is go to some of the mold lab sites and look at

their images. It might give you a rough idea but the only

certainty is under a microscope by someone trained. Even better,

Google " green mold " and click on " images. " Note the one labeled

" the dreaded green mold. " Also compare Penicillium images with

Aspergillus. The spores of each cannot be separated even under a

microscope, they need to see how they grow and how they form

spores to tell them apart.

Identifying mold solely by color is like identifying cats solely

by color. Lot's of commonalities but even more differences.

Especially critical ones like a yellow tabby and a yellow puma.
