“…Nigrospora species have also been commonly recorded as plant pathogens on many important economic crops, fruits and ornamentals. Examples include N. oryzae causing stem blight on Brassica juncea in India ( Sharma et al 2013 ), N. sphaerica causing leaf blight on Camellia sinensis in China ( Liu et al 2015 ) and N. musae causing ‘squirter’ disease on bananas ( Jones & Stover 2000 ). In addition, N. sphaerica is an opportunistic pathogen causing onychomycosis in humans ( De Hoog et al 2000 , Fan et al 2009 ) and corneal ulcer ( Kindo et al 2014 ).…”

Phylogenetic reassessment of Nigrospora: ubiquitous endophytes, plant and human pathogens

et al. 2017

Species of Nigrospora commonly occur as plant pathogens, endophytes or saprobes, and have been shown to be extremely interesting for the discovery of novel metabolites. The familial placement, as well as phylogenetic relationships among Nigrospora species remain ambiguous. In this study, Nigrospora (= Khusia) is confirmed as a monophyletic genus belonging to Apiosporaceae (Xylariales), based on a phylogeny inferred from LSU sequence data. A multi-locus phylogeny based on ITS, TEF1-α and TUB2, in conjunction with morphological characters, host associations, and ecological data was employed for species delimitation in Nigrospora, as well as identification of 165 recently collected isolates from China, and three from Europe. In total 13 novelties are proposed including 12 new species and 1 new combination. Five species are re-described based on an examination of type specimens and/or fresh collections. New species described in this paper include: N. aurantiaca, N. bambusae, N. camelliae-sinensis, N. chinensis, N. guilinensis, N. hainanensis, N. lacticolonia, N. osmanthi, N. pyriformis, N. rubi, N. vesicularis and N. zimmermanii. Furthermore, N. vietnamensis is transferred to Arthrinium. Our results indicate a high level of species diversity within Nigrospora, with a general lack in host specificity. Taxa that cluster basal in Nigrospora have wide host ranges, whereas those that diverged later tend to have narrow host ranges. The currently available data suggest, therefore, that the general evolutionary direction in the genus Nigrospora is from a wide to a narrow host range.

“…Nigrospora is generally recorded as endophytes, humus and plant pathogens on fruits, economic crops and ornamental plants (Wang et al., 2017). Nigrospora oryzae is a species of Nigrospora that causes ear rot of corn (Money, 2016) and stem blight on Brassica juncea (Sharma et al., 2013), which have also been reported from paddy rice (Bianchini & Stratton, 1999; Hocking, 2014). Mangrove forest is also reported as one of the hosts of Nigrospora (Shang et al., 2012; Wei et al., 2012; Xia et al., 2011).…”

Fungal Aerosol Diversity Over the Northern South China Sea: The Influence of Land and Ocean

et al. 2022

Fungal aerosols are ubiquitous in the atmosphere and can directly and/or indirectly affect the atmospheric cloud formation process, which play an important role in global climate change and human health. In this study, we performed a comprehensive study on airborne fungi over the northern South China Sea (NSCS). Total suspended particle (TSP) samples were collected during a cruise campaign in the NSCS, and fungal community structure was obtained via high‐throughput sequencing method. The abundance of Ascomycota (AMC) was much higher than that of Basidiomycota (BMC) in the marine fungal aerosols over this region. We observed relatively high abundances of Nigrospora and Cladosporium, two genera belonging to AMC, in the near‐coast samples compared to those in the open‐ocean samples. Therefore, we proposed that they could be used as the potential terrestrial source indicators in this region. The richness of fungal diversity and composition of fungal community were found to be dependent on the distance to the Asian continental coast, suggesting the strong influence of terrestrial sources. Over the open ocean, terrestrial and marine contribution could significantly impact the diversity richness and community structure of the fungal aerosols. This study could improve the current understanding of fungal aerosols on their characteristics and influencing factors over the oceanic area.

“…Nigrospora species have been isolated as endophytes from leaves and stems of various plants, or as saprobes from detritus, dead larvae or leaf litter. Nigrospora species have also been commonly recorded as plant pathogens on many important economic crops, fruits and ornamentals plants (Sharma et al 2013;Wang et al 2017). Coprinus has not been registered as a plant pathogen or saprophyte, however it is usually found in grassy places, particularly under trees and shrubbery (Uljé and Bas 1988).…”

The study of the fungal community composition in house dust is useful to assess the cumulative exposure to fungi in indoor environments. The objective of this research was to characterize the fungal diversity of house dust and its association with the environmental conditions of bedrooms. For this, the dust was collected from 41 bedrooms of children between the ages of 8 and 9 with a family history of asthma, residents of Havana, Cuba. The fungal content of each sample was determined by two methods: plate culture with Malt Extract Agar and by direct microscopy. An ecological analysis was carried out from the fungal diversity detected. To describe the factors associated with the fungi detected, bivariate logistic regression was used. Through direct microscopy, between 10-2311 fragments of hyphae and spores corresponding mainly to Cladosporium, Coprinus, Curvularia, Aspergillus/Penicillium, Xylariaceae, and Periconia were identi ed. Through the culture, 0-208 CFU were quanti ed, where Aspergillus, Cladosporium, and Penicillium predominated. The culturability evidenced the differences between the quanti cation determined by both methods. A positive relationship was found between the type of cleaning of the furniture, the presence of trees in front of the bedroom, indoor relative humidity, indoor temperature, the presence of air conditioning by air conditioning and natural ventilation with speci c spore types and genders. The use of two different identi cation methods allowed to detect a greater fungal diversity in the residences evaluated. Monitoring the exposure to these fungal allergens in childhood can help to prevent sensitization in the allergic child, the development of asthma and other respiratory diseases.
