Yuck!
I've seen these spiders.
Alot of people,including my wife,confuse wolf spiders with brown recluse.Wolf spiders will turn and run when you put anything in front of them,a brown recluse will not.The larger,brown spiders are usually just wolf spiders.A brown recluse doesn't get as large.Just something to keep in mind:D
Do a search on wolf spider to see the difference.
