Plain facts about the name
People usually mean Stachybotrys chartarum, a dark greenish-black mold that grows on material kept wet for a long period. Color alone does not identify it, and several ordinary molds look the same on a wall.
Dark growth is what makes most people call. Tucson Mold Removal Pros handles it the same careful way as any other mold in a Tucson property: contain the area, stop the water, remove what cannot be cleaned and check the result.
Dark growth usually means material has been wet for a while rather than splashed once. In Tucson that often traces back to a slow roof leak found after the monsoon, a condensate line that backed up in July, or a supply line dripping behind a cabinet.

The color of growth does not change the method. Tucson Mold Removal Pros works to the same sequence whatever shade the patch turns out to be, because the material and the moisture decide the job.

Mold can irritate eyes, skin and airways, and people with asthma or allergies may react more. Nobody on a remediation crew can diagnose a symptom, and questions about health belong with a doctor.
Disturbing dark growth without sealing the area spreads it. The space is contained and filtered, material that cannot be cleaned is removed, and hard surfaces are cleaned once the source is dry.
A laboratory name rarely changes the repair. If growth is visible and you know which leak caused it, the material still has to come out and the water still has to stop, whatever the species turns out to be.
Testing is worth the money when you need documentation for a landlord, a buyer or a property manager, or when someone in the household keeps reacting and nobody can find the source. Tucson Mold Removal Pros explains which of those applies to your situation.

Any mold growing indoors on wet material should be removed, and the removal method is the same. Mold can irritate eyes, skin and airways, and people with asthma or allergies may react more. Tucson Mold Removal Pros does not make health assessments; that is a conversation for your doctor.
No. Several common molds are dark, and color varies with the material underneath. That is one reason Tucson Mold Removal Pros focuses on the wet material and the source rather than naming the growth, as explained on the inspection page.
Leave it alone. Scrubbing or spraying dark growth sends spores into the rest of the house and makes the affected area harder to define. Keep the door closed, stop the water if you can do so safely, and let the area be inspected first.
