Phymatotrichopsis omnivora
TaxID: 231936
Basic Information
Phymatotrichopsis omnivora
Cotton Root Rot
Texas root rot (also known as Phymatotrichopsis root rot, Phymatotrichum root rot, cotton root rot, or, in the older literature, Ozonium root rot) is a disease that is fairly common in Mexico and the southwestern United States resulting in sudden wilt and death of affected plants, usually during the warmer months. It is caused by a soil-borne fungus named Phymatotrichopsis omnivora that attacks the roots of susceptible plants. It was first discovered in 1888 by Pammel and later named by Duggar in 1916. A monograph of this disease, which includes a historical review, was written by R.B. Streets and H.E. Bloss in 1973.

Morphological Features
Phymatotrichopsis omnivora (syn. Phymatotrichum omnivorum) is an asexual fungus with no known sexual stage. It produces long, septate hyphae that form a dense mycelium. A distinguishing morphological feature is the production of cruciate (cross-shaped) hyphae that branch at right angles from the main hyphae, which are characteristic for identification. The fungus forms mycelial strands (rhizomorphs) visible to the naked eye, approximately 200 µm in diameter, bearing acicular hyphae. On culture media, the mycelium is sterile in its early stages, with thin strands at right angles and swollen nodes bearing 2–4 branches. Conidia are unicellular, hyaline, globose (4.8–5.5 µm in diameter) or ovate (6–8 × 5–6 µm), occasionally formed on epigeous spore mats but considered sterile and non-functional. Sclerotia are irregular in shape, brown to black, 1–5 mm in diameter, serving as the primary survival structures.
