Unknown 31 = Aphanoascus fulvescens
|A 4-year-old Australian Sea-lion from Kangaroo Island presented with scaly, cutaneous lesions on the back flipper. Skin scrapings showed the presence of fungal hyphae and the culture grew the fungus shown below.|
|Direct Microscopy (KOH Parker ink)|
KOH mount of infected skin scales showing typical dermatophyte-like hyphae breaking up into arthroconidia.
Colonies are moderately fast growing, white to tan with the production of numerous spherical, pseudoparenchymatous, buff to light brown cleistothecia (non-ostiolate ascocarps).
Aphanoascus fulvescens has a Chrysosporium anamorph showing typical pyriform to clavate-shaped conidia with truncated bases, which are formed either intercalary, laterally or terminally.
Asci are subspherical to ellipsoidal and eight-spored. Ascospores light brown, yellowish to pale brown in mass, irregularly reticulate to lens-shaped.
