Macroscopic morphology

Colonies on potato dextrose agar at 25°C are initially white, soon becoming dark gray to black with a black reverse. Rapid growth. Texture is woolly to cottony.

Microscopic morphology

Hyphae are septate and dark. Conidiophores may be up to 120 µm in length, are sympodial, geniculate, simple or branched, bearing conidia through pores or openings (poroconidia). Conidia measure 12-37 x 5-11 µm and have predominately 5-distosepta or pseudosepta (septa that do not extend to the cell wall with cells enclosed within sacs) and 6 cells. Conidia germinate from both poles.

Special notes

The conidia of B. hawaiiensis have a more overall delicate look and are generally somewhat narrower than either B. spicifera or B. australiensis. Phaeohyphomycosis due to B. hawaiiensis ranges from superficial to systemic disease. Literature citations include subungual hyperkeratosis of a big toe [1960], subcutaneous infections [478], nasal phaeohyphomycosis [1239], invasive [1461], [396]and allergic fungal sinusitis [778], and allergic bronchopulmonary disease [1997]. Ocular mycoses include corneal ulcers [74], endogenous endophthalmitis [1739], and phaeohyphomycotic orbitopathy [1461]. It has also been cited as the etiololgic agent of fungal peritonitis [789] and granulomatous encephalitis [1586].
