Dry rot species of fungi cause brown rot decay, preferentially removing cellulose and hemicellulose from the timber leaving a brittle matrix of modified lignin. The term "dry rot" is somewhat misleading, as both species of fungi "Serpula lacrymans" and "Meruliporia incrassata" require an elevated moisture content to initiate an attack on timber (28–30%). Once established, the fungi can remain active in timber with a moisture content of more than 20%. At relative humidities below 86 percent, growth of "Serpula lacrymans" is inhibited, but it can stay dormant at relative humidities down to 76 percent. These relative humidities correspond to equilibrium moisture contents
The Amity Affliction then hired drummer, Troels Thomasson, Chris Burt on Guitar (originally on Bass), Ahren Stringer now on bass and the addition of a keyboardist, Trad Nathan. The Amity Affliction released a new five track EP entitled "High Hopes" which was named for the house in which "The Amityville Horror" took place. The first pressing came in a CD/DVD package. The DVD featured the band discussing the recording of the EP, it also featured the band on the road and performing. The band released their debut studio album in 2008, entitled "Severed Ties".
