Building mycology deals with the study of fungi in and around the built environment which have direct and indirect effects on the health of the building fabric, its materials, structures, environments and occupants (Singh, 1991). Building structures and environments provide specialized microclimates and ecological niches in their ecosystem for the settlement, growth and proliferation of a variety of fungal organisms. These fungi can cause damage to the building structures, decorations and contents and can raise concerns for the indoor air quality and the health of the building’s occupants (Cartwright and Findlay, 1958; Richardson, 1980; Allsopp and Seal, 1986; Singh and Walker, 1994).
