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.
