well it took me a while...it was a tuft question to answer, but finally here it is...! Gnaphosid Spiders are common outdoor spiders. A specific Gnaphosid spider is known as a parson spider which is occasionally indoors. Parson spiders do not like water or cold weather. the parson spider is a meduim-sized spider (1/2 inch long). Parson spiders are hunting spiders and do not spin webs...and when they hunt it isn't pretty... anyways, they hunt at night and during the day, they are usually found out doors under stones or loose bark in silken retreats. Indoors they are found under objects like chairs or tiny holes in furtiture, or in cracks and crevices. And YES they are dangerous! Hope this helps!
If you are in the United States or southern Canada, and you have found this spider sheltering in a shed or cellar, it might be a Brown Recluse, Loxosceles reclusa. It will be quite small with long legs, brown and blackish in color, and have a somewhat violin-shaped marking on its back. It is extremely poisonous. Stay away from it.
Spiders, in general, are more than one color or have colored spots on them. Purseweb spiders are black. They are found in Kentucky and almost never seen by people.

A Woodlouse Spider!
The black-handed spider monkey has a light to medium brown body and darker limbs with the hands and feet usually black in color. The tail is sometimes longer than the body. When the animal is on the lookout, it stands or walks on two feet, using the tail to hold on to a support.
A black widow. This spider is only a black widow if the entire spider is black, with a round-ball looking back-body, female variety if there is a red hourglass shape marking on the underside of the spider. From the top black widows are completely black.
That could be anything, there are 100s of spiders that fit that description, please rephrase the question with the area, climate and place that you've seen the spider and a more accurate description. This kind of spider was in my house in PA. It has the body size of about a little larger than a pencil point, in a ball shape, but the body was larger than the avg. size of the head. Has think brown legs. Body is kinda like a black widow.. but brown and much smaller..
