Fusarium chlamydosporum complex
Fusarium chlamydosporum complex contains five phylogenetically distinct species
and is common in soils and the rhizosphere of numerous vascular plants worldwide.
It is occasionally isolated from human and animal infections (O’Donnell et al. 2009b,
Guarro 2013).
RG-1 organisms.
Morphological Description: Colonies growing rapidly, with abundant aerial mycelium,
deep pink, red or ochraceous to brownish; reverse carmine red or tan to brown.
Sporodochia orange, flesh-coloured or ochraceous. Conidiophores scattered over the
aerial mycelium, branched; numerous polyblastic conidiogenous cells are present.
Macroconidia rarely produced and appearing only on sporodochial phialides, usually
three-(some up to five)-septate, slightly curved, 30-38 x 3.0-4.5 μm, with no distinct
foot-shaped cell. Microconidia and blastoconidia fusiform, rounded apically and
tapered towards the base, single-celled to one-(some up to three)-septate, 6-26 x 2-4
μm. Chlamydospores abundant, intercalary, often roughened.
Fusarium chlamydosporum complex, culture showing pink to
ochraceous to brownish surface and a carmine red reverse.
Antifungal Susceptibility: F. chlamydosporum complex (Australian National
data); MIC µg/mL.
