Rhinocladiella atrovirensColonies are restricted, velvety or lanose, olivaceous, often slightly mucoid at the centre; reverse dark olivaceous green to blackish. Conidiophores are short, brown, thick-walled. Conidiogenous cells are cylindrical, intercalary or free, 9-19 x 1.6-2.2 µm; denticulate rachis up to 15 µm long, with crowded, flat or butt-shaped, unpigmented conidial denticles. Conidia are hyaline, thin- and smooth-walled, short-cylindrical, with truncate basal scars, 3.7-5.5 x 1.2-1.8 µm. Budding cells, if present, are hyaline, thin-walled, broadly ellipsoidal, 3.0-4.3 x 1.7-2.5 µm. Germinating cells are inflated, spherical to subspherical, 4.5-6.0 µm. An annellidic Exophiala synanamorph may be present. RG-1 organism.
Culture, conidiophores showing a terminal denticulate rachis,
MIC data is limited. Antifungal susceptibility testing of individual strains is recommended.
Clinical significance:Rhinocladiella contains 6-8 species, with two species of medical interest; R. atrovirens and R. aquaspersa. Mycosis: PhaeohyphomycosisFurther reading:Domsch, K.H., W.
