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 Mall Wood Green The Mall Wood Green The Mall Wood Green is a large shopping centre and residential complex in Wood Green, north London. It is generally still referred to by its former name of Wood Green Shopping City. The centre was built in the 1970s as "Wood Green Shopping City", on the site of the former Noel Park and Wood Green railway station. Initially it included a number of unusual features, most notably a giant wooden climbing frame in the shape of a frog. The centre was opened on 13 May 1981 by HM Queen Elizabeth II.
