Ascospores biseriate, fusiform 7-transseptate, two or many rows of longitudinal septa, muriform
, constricted only at the central septum, dark brown to brown, surrounded by a thin, hyaline mucilaginous sheath.
Chromoblastomycosis is a chronic fungal infection of the skin and subcutaneous tissue caused by pigmented fungi which produce sclerotic or muriform
bodies in tissue and is characterised by slow growing exophytic lesions usually on feet and legs.
Conidia solitary dark brown muriform
with smooth or rough walled sub-globose.............Stemphylium sp.
It is characterized by its muriform
, brown to reddish brown or yellowish or yellowish brown ascospores, with one to several longitudinal septa, ovoid to ellipsoid-fusoid, usually constricted at the first-formed septa.
On potassium hydroxide (KOH) mounts or histologic examination, the thick-walled cells (muriform
bodies) of chromoblastomycosis are diagnostic.
Thallus brown (or green when wet), squamulose; spores muriform
The identification of muriform
cells in samples and culture clinch the diagnosis.
These are known as sclerotic bodies, muriform
cells, or medlar bodies, and are 5-12 mm in diameter.
 Sclerotic or muriform
bodies are thick-walled single cells or cell clusters seen as brown-colored "Copper pennies." They can also be detected in routine H--and E-stained biopsy specimens.
Thallus white; alga absent; spores muriform
; conidia bacilliform JULELLA 2.
Histopathology of these plaques showed chronic non-specific inflammatory cell infiltrate along with multiple brown pigmented muriform
cells in clusters which confirmed chromoblastomycosis.
