This appears to be a male spider in the family Agelenidae (funnel web/grass spiders), likely in the genus Tegenaria (see http://www.washington.edu/burkemuseum/spidermyth/images/gigantea.jpg for an image). Males in this family often wander quite some distance from their web, and then come to human attention when their wandering results in their accidental entrapment in tubs and the like. In spite of their appearance, they should pose no threat to human health. One species in this genus, the so-called ‘hobo spider’ (Tegenaria agrestis), has been implicated in cases of slow-healing ulcers (necrotic arachnidism) following a bite, but some controversy still exists on this subject. See http://www.xs4all.nl/~ednieuw/Spiders/Agelenidae/Agelenidae.htm for much more information on this group of spiders. Ed Saugstad, retired entomologist, Sinks Grove, WV.
