Cladosporium sphaerospermum (left)

This picture was made from a B and W negative not a coloured slide!

Left:  This  photomicrograph of Cladosporium was on the cover of the original printing of my book ' The Genera of Hyphomycetes from Soil' published in 1968.  It was also the frontspiece illustration of  that same book.  The original was a  negative on black and white film (Kodak Panatomic X).   However with the miracle of modern computer technology and help from Adobe Photoshop in particular, I was able to make a reasonably good facsimile of a colour shot! 

Right: This diagram shows the typical tree-like (dendroid) habit of Cladosporium.   The conidia are blstospores produced in acropetal succession (ypuingest at the apex). If two or three conidia develop simultaneously a the tip this results in the prouction of branching chains of conidia so characterisitc of the genus.
