Cockroach Tinea versicolor bug

A 34-year-old man seeks the advice of his primary care physician because of an asymptomatic rash on his chest. There are coalescing light brown to salmon-colored macules present on the chest. A scraping of the lesions is viewed after a wet preparation with 10% potassium hydroxide solution. There are both hyphal and spore forms present, giving the slide an appearance of "spaghetti and meatballs." In addition, the lesions fluoresce to a yellow-green appearance under a Wood's lamp. Tinea versicolor is diagnosed. Which of the following microorganisms is responsible for this skin infection?
A. Fusarium solani
B. Malassezia furfur
C. Sporothrix schenkii
D. Trichophyton rubrum
