Unknown 17 = Purpureocillium lilacinus
|A 57 year-old male bricklayer who developed lesion on his right arm. A punch biopsy was taken and cultures grew the fungus shown below.|
Colonies are fast growing, suede-like and vinaceous to violet in colour, but never green or blue-green as in Penicillium.
Conidiophores are erect, 400-600 um in length bearing branches with densely clustered phialides. Conidiophore strips are 3-4 um wide, yellow to purple and are rough walled. Phialides are swollen at their bases, gradually tapering into a slender neck. Conidia in chains are ellipsoidal to fusiform, smooth walled to slightly roughened hyaline, purple in mass 2.5-3.0X2.0-2.2 um.
