Ceratocystis Paradoxa

Two strains of Thielaviopsis paradoxa, one light and one dark, were isolated from diseased cuttings of sugarcane in Puerto Rico. Perithecia were produced when the dark strain was crossed with the light strain in potato dextrose agar medium at 24° to 28° C. The perithecia obtained are characteristic of Ceratocystis paradoxa (horn-like appendages on the base of the perithecia and long, pointed ostiolar hyphae). Ascospore isolations consistently resulted in the recovery of typical T. paradoxa culture. No perithecia were produced when cultures of the same isolates were crossed. This constitutes the first report on formation of the sexual stage of T. paradoxa from sugarcane in vitro.

Severity Of The Disease

Banana shrub (Michelia figo (Lour.) Spreng.) is an evergreen grown in southern landscapes in hardiness zones 7 to 9. A powdery mildew disease has been observed sporadically on this plant for several years in the Baton Rouge area during fall months, but symptoms were always mild. During the summer and fall of 1998, banana shrub plants were observed with moderately severe powdery mildew infections that resulted in leaf chlorosis, distortion, and some defoliation. An Oidium sp. was present on both leaf surfaces, but sporulation was more abundant on the abaxial surfaces. Conidia were ellipsoid, produced in chains, devoid of conspicuous fibrosin bodies, and averaged 37 × 19 μm. No sexual stage was found. Conidia brushed from infected leaves to healthy leaves of a potted banana shrub maintained in a greenhouse caused new infections in 5 to 8 days. Factors responsible for the increased severity of the disease in 1998 are unknown, but the unusually dry summer may have contributed to the increased incidence of this disease. An Oidium sp. was listed on M. figo in Australia and the United States (1), but no other reports were found to confirm this. This is the first report of the occurrence of a powdery mildew on M. figo in the United States. Reference: (1) K. Amano. Host Range and Geographical Distribution of the Powdery Mildew Fungi.

A sporulating Aspergillus is described from a piece of Eocene amber originating from the Dominican Republic. The Aspergillus most closely resembles a form of the white spored phase of Aspergillus janus Raper and Thom. This is the first report of a fossil species of Aspergillus.
