Ceratocystis fimbriata is a fungus and a plant pathogen, attacking such diverse plants as the sweet potato and the tapping panels of the Para rubber tree (moldy rot).It is a diverse species that attacks a wide variety of annual and perennial plants. There are several host-specialized strains, some of which, such as Ceratocystis platani that attacks plane trees, are now described as distinct Family: Ceratocystidaceae.

Five new species ofCeratocystis wood staining fungi are described. The speciesCeratocystis abiocarpa is common in recently killed subalpine fir (Abies lasiocarpa (Hook) Nutt.), trees or felled logs in the Central Rocky Mountain area from Wyoming to Northern Arizona and New by: The canker mainly stresses trees, allowing insect borers and other cankers (Cytospora, Sooty-bark) to kill the trees. This is the most common canker on aspen after Cytospora canker throughout western states. Biology and Disease Cycle. Ceratocystis fimbriata overwinters in cankers. It is spread from tree to tree primarily by insects visiting wounds.

Corresponding author. Abstract. During routine surveys for possible fungal pathogens in the rapidly expanding plantations of Eucalyptus and Cunninghamia lanceolata in China, numerous isolates of unknown species in the genus Ceratocystis (Microascales) were obtained from tree wounds. In this study we identified the Ceratocystis isolates from Eucalyptus and Cunninghamia in the GuangDong, GuangXi, FuJian and Cited by: 9. Ceratocystis fimbriatomima, a new species in the C. fimbriata sensu lato complex isolated from Eucalyptus trees in Venezuela. Fungal Diversity Species of Ceratocystis represent a group of important plant pathogens as well as saprobes that occur, primarily on woody substrates. Oak Wilt - Ceratocystis fagacearum The oak wilt pathogen Ceratocystis fagacearum is only known in the north central, south central and eastern parts of the US (Sinclair and Lyon, ).First clearly identified in the s in the upper Mississippi valley, its apparent spread in the subsequent 20 years () may be primarily the result of surveying rather than actual spreading (Appel, ).
Notes on Taxonomy and Nomenclature Top of page Ceratocystis fimbriata, the type species of the genus, was originally described on sweet potato (Ipomoea batatas) in (Halsted, ). Saccardo () transferred the species to Sphaeronaema, Elliott () transferred it to Ceratostomella, Melin and Nannfeldt () transferred it to Ophiostoma, and Davidson () transferred it to. Introduction. Ceratocystis was established in to accommodate C. fimbriata, a pathogen causing black rot of sweet potatoes in the USA (Halsted ).The genus now includes many important fungi including important pathogens of plants and the causal agents of sap stain in timber that are symbiotic associates of insects (Fig. 1).These fungi have ascomata with round usually dark bases Cited by: Ceratocystis wilt is among the most important diseases on mango (Mangifera indica) in Brazil, Oman, and Pakistan. The causal agent was originally identified in Brazil as Ceratocystis fimbriata, which is considered by some as a complex of many cryptic species, and four new species on mango trees were distinguished from C. fimbriata based on variation in internal transcribed spacer by: Bretziella, a ne genus to accommodate the oak ilt fungus 3 During the course of the six decades following the Hunt () monograph, the oak wilt fungus was treated as Ceratocystis fagacearum, with its asexual (anamorph) name, Chalara quercina as heterotypic synonym (Nag Raj and Kendrick , Upad- hyay , Seifert et al. , De Beer et al. b).Cited by:
