 and Thread parasites (Coniomycetes and Hyphomycetes). 

 They are all-pervading, existing in chemical solutions, in 

 tropical and polar climates, vegetating on glass, iron and 

 horn, as well as wood and foliage, and studding the silks 

 and gloves in a lady's wardrobe as freely as the dead 

 straws by the pool side. Moulds are even traced in 

 fossil wood.
