Here are some of the most commonly found mould genera in water damaged houses, as seen under the microscope!

Aspergillus
– Produces mycotoxins
– Allergenic
– Easily airborne
– Difficult to spot on surfaces

Penicillium
– Produces mycotoxins
– Allergenic
– Easily airborne
– Difficult to spot on surfaces

Cladosporium
– Allergenic
– Most commonly found mould

Chaetomium
– Allergenic
– Produces mycotoxins
– Normally found on materials that have been wet for an extended period of time

Stachybotrys
– Allergenic
– Produces mycotoxins
– Normally found on materials that have been wet for an extended period of time
– The so-called “toxic black mould”

Fusarium
– Allergenic
– Produces mycotoxins

Trichoderma
– Allergenic
– Produces mycotoxins
– Grows in sticky clusters

Hyphae (not a mould genera, but the “roots” that mould put into material.)
– Allergenic (some reports indicate that hyphae fragments are even more allergenic than their mould spores)
