A review and updated checklist of Corynespora (Dematiaceous hyphomycetes) diversity and distribution reported from all over the world is prepared and presented over here based on available bibliographic survey upon published data. After critical review and verification, a total of 207 taxonomic records of Corynespora has been found in Index Fungorum, among them 179 spp. (86.47%) have been found as nomenclaurally valid/accepted taxa, while 14 spp. (6.76%) found to be transferred to other different taxa, 11 spp. (5.31%) synonymously transferred to other Corynespora taxa, and 3 spp. (1.44%) found as invalid taxa. In all word-wide recorded Corynespora species, 114 spp. (55.07%) have been found as foliicolous, 90 spp. (43.47%) as lignicolous, 2 spp. (0.96%) as lichenicolous, and 1 sp. (0.48%) from the air. Similarly, 184 spp. (88.88%) have been reported on Angiosperms, 1 sp. (0.48%) on Gymnosperms, 22 spp. (10.62%) recorded on unidentified plant parts/taxa, whereas no one species recorded on Bryophytes and Pteridophytes. Likewise, 166 spp. (80.19%) have been recorded on 54 families of Dicot, 18 spp. (8.69%) on 6 families of monocot, 1 sp. (0.48%) on 1 family of Gymnosperm, and 22 spp. (10.62%) on unidentified plant parts/taxa. Furthermore, the distribution of Corynespora spp. have been recorded from 34 countries, in which the species richness recorded maximum in India (80 spp., 38.64%) followed by China (31 spp., 14.97%), USA (11 spp., 5.31%), and other countries.  Besides, distinguishing features of valid Corynespora spp. are also provided along with their hosts/substrate, host’s family, distribution (country), and references. This paper provides an updated checklist of Corynespora spp. reported from all over the world with their current status in the context of current nomenclature. In order to get all collected scientific information at one shop for further scientific study on exploration of Corynespora, this compiled up-to-date checklist with their comparative morphology would be vital and helpful to the researchers of concern fields as well as allied disciplines.

3. First record of Eutypella vitis causing branch dieback on new host trees in Canada

Authors: Ilyukhin E, Bulgakov T, Markovskaja S

Recieved: 29 October 2020, Accepted: 31 December 2020, Published: 26 January 2021

Eutypella vitis is reported for the first time on several new host trees viz. Fagus grandifolia, Fraxinus pennsylvanica and Syringa reticulata with associated branch dieback symptoms in the Niagara Region of Southern Ontario, Canada. Morphological characteristics and phylogenetic analyses of ITS sequence data confirmed the species identification. Eutypella vitis is known as a woody plant pathogen causing dieback of grapevines and other economically important fruit trees widely cultivated in Ontario. The fungus ability to infect several alternate new hosts can promote its faster and wider spread across vineyards and consequently increase a dieback hazard to viticulture in Canada. 

Keywords: Diatrypaceae – Eutypa dieback – grapevines – multi-host plant pathogen

 

4. Endophytic mycobiota of wild medicinal plants from New Valley Governorate, Egypt and quantitative assessment of their cell wall degrading enzymes

The present study isolated and identified 32 species of endophytic mycobiota belonging to 18 genera associated with 8 wild medicinal plants collected from El-Kharga Oasis, New Valley Governorate, Egypt. Fusarium was the most common genus followed by Alternaria and Aspergillus. Convolvulus arvensis was the plant with the highest number of endophytes over the other plant species, while Moringa oleifera reported the lowest number of endophytes. In addition, the entomopathogenic fungus Beauveria bassiana; was recorded for the first time from leaves of Portulaca oleracea. One hundred and twenty-three isolates representing 32 species were screened for their abilities to produce pectinase, carboxy methyl cellulase (CMCase) and avicellase enzymes on sucrose free-Cz supplemented, individually with 1% pectin or 1% CMC or 1% avicel as a sole carbon source, respectively. Ninety-four isolates produced pectinase while 66 isolates produced cellulases. The quantitative assays of the three enzymes for high-producers were performed in submerged fermentation using sucrose-free Cz broth. Aspergillus was the superior in the production of the three enzymes with the potent strains were A. terreus AUMC 14287 for CMCase (22.0 IU/ml/min) and avicellase (47.868 IU/ml/min) and A. terreus AUMC 14278 for pectinase (225.43 IU/ml/min).

Keywords: cellulose – endophytic fungi – medicinal plants – pectinase – submerged fermentation

A study was undertaken to collect and identify saprobic fungi associated with Musa spp. (banana) from Taiwan, China, and Thailand. Samples were collected during the dry season and their morpho–molecular relationships were investigated. Five brown pleosporalean hyphomycetous taxa in Periconiaceae and Torulaceae viz. Periconia cortaderiae, P. delonicis, Torula chromolaenae, T. fici, and T. masonii were identified for the first time from Musa spp. (Musaceae). Phylogenetic analyses of a combined SSU, LSU, ITS, RPB2 and TEF DNA sequence dataset further justified the taxonomic placements of these five taxa in the above mentioned families. Periconia delonicis is reported for the first time on a monocotyledonous host and T. masonii is the first geographical record from Taiwan.

Keywords: Dothideomycetes – Periconia – Pleosporales – taxonomy – Torula
