Ophiobolus hydeisp. nov. (Phaeosphaeriaceae, Ascomycota) fromCirsiumandPhlomoidesin Uzbekistan

Abstract

We introduce a new fungal species, Ophiobolus hydei, from dead stems of Cirsium alatum (Compositae) and Phlomoides brachystegia (Lamiaceae), based on morphological and phylogenetic evidence. The species was collected from the Mountains of Western Tien Shan and southwestern Hissar in Uzbekistan. Ophiobolus hydei is characterized by globose to subglobose ascomata with short to long papilla, cylindrical to subcylindric-clavate asci, broad pseudoparaphyses, and scolecosporous, yellowish-brown to brown, filiform, multiseptate ascospores that can split into several part-spores at the septa. Multigene phylogenetic analyses using a combined gene analysis of ITS, LSU, SSU, and TEF1-α indicated that the new species has a close affinity to Ophiobolus ponticus, but differs from that species in the micromorphological characteristics of the ascomata, asci, and ascospores, as well as biogeographic distribution. A distribution map, morphological descriptions, and illustrations with colour photographs of the novel species are provided.

Species Diversity With Comprehensive Annotations of Wood-Inhabiting Poroid and Corticioid Fungi in Uzbekistan

“…Fungal names used in other regional floras have often been applied to fungi in Uzbekistan. However, the Uzbek fungi often represent new, unrelated species as was shown for Uzbekistan ascomycetous microfungi Gafforov, 2001, 2002;Gafforov and Hoshino, 2015;Gafforov, 2002Gafforov, , 2010Gafforov, , 2015Gafforov, , 2016aGafforov and Rakhimov, 2017;Gafforov et al, 2019;Wanasinghe et al, 2017Wanasinghe et al, , 2018aSamarakoon et al, 2018;Pem et al, 2018Pem et al, , 2019aHyde et al, 2019Hyde et al, , 2020Yuan et al, 2020). Basidiomycetous fungi have received even less attention than ascomycetous microfungi (Gafforov, 2014;Gafforov et al, 2014.…”

Importance of catalpa groups in cultural city greening in the case of Uzbekistan

“…Propagation of the studied plants from seeds, treatment with stimulants before sowing in seeds, and biometric measurements were performed using generally accepted methods [8,10,11].…”

“…In accordance with the program of landscaping and beautification of roads, city streets, it is planned to plant more than 1.6 million trees and shrubs along the roads, and 782,000 (103,000 of them in the capital) on city streets. In the program, plants such as pine, maple, oak, chestnut, ash, Indian nasturtium are shown as ornamental seedlings [5,8].…”

“…Therefore, for urban landscaping, it is necessary to select and propagate introduced highly ornamental tree species that are resistant to various toxic gases emitted into the air by cars, extreme temperatures and cooling, as well as drought and soil salinity [4,8].…”

Types and quantities of weeds found in corn fields and the effect of herbicides on grain yield

“…For this it is necessary to use all available reserves. In the conditions of modern intensive farming, weed control is one of the most important elements of the farming system, on which the increase in crop yields depends [10,11]. Corn is perhaps the most valuable crop grown for animal feed, as well as for grain.…”
