Ainsworth and Bisby’s dictionary of the fungi. Myriangium hispanicum CBS Here the isolate CPC is tentatively identified as E.
The description provided in the original publication is rather incomplete and based on a seemingly sterile specimen. These are often raised, exhibiting cracks, and hence are referred to as scabs. mangoferae

Usually two to three week intervals till fruit is half size and weekly sprays after in order to protect that fruit from infection. Run Zhang 1 and Dr. The strain CPCwhich was isolated from the same host in Brazil, is designed here as ex-epitype. Structures were mounted in clear lactic acid, and 50 measurements determined per structure, with extremes of conidial measurements given in parentheses. Slightly raised leaving depression on the lower side of leaves.
If you would like to know more about cookies and how they work, please visit www. In wet weather, numerous small, brown, necrotic lesions or shot holes may form on young leaves leading to defoliation. Culture characteristics based on CPC Confirmation of the presence of mango scab requires microscopic examination of material from fruit, stems or leaves, and culture of the organism. The disease initially presents as small dark brown or gray spots on the underside of leaves or fruit.
Leaves A wide range of symptoms has been observed on the leaves although these symptoms are largely overshadowed by the elsinke dramatic damage on the fruits. The rpb2 region failed mangifegae distinguish E. Symptoms include numerous small spots that are scattered or grouped to form larger patches on leaves; elongated, closely grouped to form crusts by coalescence on young shoots.
Kramer, deposited by A. These lesions range from small black spots, which could be mistaken for spray injury, to small and large scarred areas, the large areas being accompanied with a depressed distortion of the fruit. Later, Jenkins b separated them as distinct species according to the three anthracnose diseases that they caused, and treated Phyllosticta rosarum as Sphaceloma rosarum based on its typical Sphaceloma morphology of the asexual morph.
CubaWajay, Havana, on Phaseolus lunatusNov.
In contrast to mango scab, injury by Amblypelta causes a much deeper depression in the fruit skin. Ex-type sequence data is, however, available for only a few species. Elsnoe holotype not found ; 24 Sep.
Jenkins available for inclusion in this paper. Sphaceloma menthae Jenkins, J. Nursery In nurseries a similar range of symptoms shot hole, numerous small necrotic lesions, distorted leaves occurs on the leaves as occurs in orchards but these tend to be more prominent on the young growth. Increased application schedules are recommended in moist climates and seasons.
The ex-epitype culture CBS Morphology Descriptions of the sexual morph are based on host material, while those of the asexual morph are based on sporulating cultures Fig. From Wikipedia, the free encyclopedia.
Ascospores irregularly arranged, oblong or fusiform with slightly elsinod rounded ends, with 2—3 transverse septa, hyaline, smooth-walled, lacking a sheath. Brazilfrom Citrus aurantiumA. Elsineo mangiferae produces brownish ascocarps in the host epidermis. Each of the other 69 species included in this study is known to occur on only one host species or genus.
Barreto2 J. Google Wikimedia Wikipedia Wikispecies. Post-harvest diseases of avocado fruits in New Zealand. More Spanish version Dr. Barrus culture CBS The LSU region was able to distinguish only 51 of the 73 Anderson holotype BPI Although treated as synonymous in literature, this has never been proven, and the Brazilian isolate treated here elsijoe likely represents a distinct species — a conjecture requiring recollecting the fungus on F.
Phylogenetic studies based on type materials are hampered by the lack of authentic cultures, and thus mangifeae from fresh collections is required to create a stable and workable taxonomy. Lesions on rlsinoe inflorescence or frutescence may initially appear similar to those of anthracnose, however, on closer inspection or microscopic examination they are seen to be raised structures in contrast to the magniferae lesions of anthracnose.
Some hosts develop severe distortions of infected organs, such as stem elongation in cassava, or twisting of infected stems of Bidens spp.
