Terminalia ivorensis, a tree of central African origin, is planted in several tropical countries for timber and veneer production. During the course of a recent disease survey, an unknown fungus was found associated with basal cankers on dying T. ivorensis in Ecuador. The fungus has orange fruiting structures and septate, fusoid ascospores, similar to those of Cryphonectria, a well-known genus ...

Fungus balls of the paranasal sinuses represent a noninvasive manifestation of fungal sinusitis. Patients are immunocompetent but no more allergic than the general population. There is little tissue reaction to the tangled mat of hyphae. If the patient becomes immunocompromised, then the fungus ball may become invasive, as illustrated by an included case report. One hundred sixty-three addition...

A phellophytic fungus Phomopsis (Endophytic fungi residing in the Bark) of Azadirachta indica screened for the presence of melanin on their hyphae using an alkali procedure, yielded a dark brown pigment. The purified pigment was subjected to various chemical and physical tests that are diagnostic for melanin. The pigment responds positively for all the diagnostic tests for melanin. Further stud...

ringworm in 1874, but he considered the fungus to be identical with that of the European ringworm. Manson (1879?82) in China was the first to describe the disease in any detail and he gave it the name tinea imbricata; he considered the fungus a non-cultivable Trichophyton, to which Blanchard gave the name Trichophyton concentricum. Castellani in Ceylon (1910-11) was the first to cultivate the f...

The new combination Calidion bombacis is proposed for the rust species formerly known as Uredo bombacis. This nomenclatural change is based on the examination of newly collected material of this fungus from a new host, Bombacopsis glabra from Brazil, and reexamination of the isotype. Until now this fungus was only known to occur in Asia (China, India and Sri Lanka). Therefore, this is also the ...

A fungus Pyrenophora tritici-repentis induces tan spot of wheat which is a foliar disease that causes yield loss to wheat crops worldwide. In this study, a new, simple and non-costly technique was performed to produce the sexual stage of this fungus in culture, within 9 weeks using wheat straw. This protocol will be helpful to researchers studying the biology of sexual stage development, diseas...

Four rust raxa in 3 genera and one form genus are newly recorded for Iran. Among these, Melampsoridium is a new genus for the Iranian rust flora. M. carpini on Carpinus sp., Coleosporium inulae on Inula salicina ssp. aspera, Puccinia saniculae on Sanicula europea and Uredo Otostegiae on otostegia persica are repoted for the first time in Iran. Number of urediniospore pores formerly believed 2 i...

in this paper the taxonomy of some previously reported taxa as cercospora apii s.lat. in iran, is discussed and some new records are listed. cercospora species on abelia grandiflora (c. deutziae), erythrina crista-galli (c. erythrinicola), euphorbia heterophylla (c. pulcherrimae) and zanthedeschia aethiopica (c. richardiicola) are new for mycobiota of iran. cercospora iridis which was previousl...
