“…Recently, Aspergillus section Candidi underwent a monographic study, with the revised section Candidi hosting nine species. Members in this section have been reported from house dust, soil, herbivore dung, indoor air, and cave environments, and occasionally from clinical specimens [ 22 ]. To our best knowledge, this is first study to isolate A. subalbidus from meju, thereby revealing its significance as a fungus colonizing food environment.…”

Aspergillus is one of the largest and diverse genera of fungi with huge economical, biotechnological, and social significance. Taxonomically, Aspergillus is divided into six subgenera comprising 27 sections. In this study, 235 strains of Aspergillus subgenus Circumdati (section: Candidi , Circumdati , Flavi , Flavipedes , Nigri, and Terrei ) preserved at the Korean Agricultural Culture Collection (KACC) were analyzed and re-identified using a combined dataset of partial β-tubulin ( BenA ), Calmodulin ( CaM ) gene sequences and morphological data. We confirmed nineteen species to be priorly reported in Korea ( A. neotritici , A. terreus , A. floccosus , A. allahabadii , A. steynii , A. westerdijkiae , A. ochraceus , A. ostianus , A. sclerotiorum , A. luchuensis , A. tubingensis , A. niger , A. welwitschiae , A. japonicus , A. nomius , A. tamarii , A. parasiticus , A. flavi , and A. oryzae ). Among the studied strains, three species ( A. subalbidus , A. iizukae , and A. uvarum ), previously unreported or not officially documented, were discovered in Korea, to the best of our knowledge. We have given a detailed description of the characteristic features of the three species, which remain uncharted in Korea.

“…We used a unified approach for species delimitation using modern methods based on the multispecies coalescent model as a starting point for the taxonomy of the studied group combined with morphological and physiological data. The phylogenetic species delimitation methods are becoming frequent in taxonomic studies, even concerning fungi ( Maharachchikumbura et al 2021 , Glässnerová et al 2022 , Sklenář et al 2022 ). Our analyses combined four molecular species delimitation methods based on different approaches (Bayesian inference: GMYC, STACEY; Maximum Likelihood: PTP; phylogenetic distance: ABGD) and all yielded largely congruent results.…”

Chloridium is a little-studied group of soil- and wood-inhabiting dematiaceous hyphomycetes that share a rare mode of phialidic conidiogenesis on multiple loci. The genus has historically been divided into three morphological sections, i.e. Chloridium, Gongromeriza, and Psilobotrys. Sexual morphs have been placed in the widely perceived genus Chaetosphaeria, but unlike their asexual counterparts, they show little or no morphological variation. Recent molecular studies have expanded the generic concept to include species defined by a new set of morphological characters, such as the collar-like hyphae, setae, discrete phialides, and penicillately branched conidiophores. The study is based on the consilience of molecular species delimitation methods, phylogenetic analyses, ancestral state reconstruction, morphological hypotheses, and global biogeographic analyses. The multilocus phylogeny demonstrated that the classic concept of Chloridium is polyphyletic, and the original sections are not congeneric. Therefore, we abolish the existing classification and propose to restore the generic status of Gongromeriza and Psilobotrys. We present a new generic concept and define Chloridium as a monophyletic, polythetic genus comprising 37 species distributed in eight sections. In addition, of the taxa earlier referred to Gongromeriza, two have been redisposed to the new genus Gongromerizella. Analysis of published metabarcoding data showed that Chloridium is a common soil fungus representing a significant (0.3 %) proportion of sequence reads in environmental samples deposited in the GlobalFungi database. The analysis also showed that they are typically associated with forest habitats, and their distribution is strongly influenced by climate, which is confirmed by our data on their ability to grow at different temperatures. We demonstrated that Chloridium forms species-specific ranges of distribution, which is rarely documented for microscopic soil fungi. Our study shows the feasibility of using the GlobalFungi database to study the biogeography and ecology of fungi.

“…The approach is unable to distinguish closely related species, especially in Aspergillus . This genus comprises 27 sections, with causative agents of disease of humans and animals mostly found in sections Fumigati , Flavi , Terrei , Nigri , and Nidulans ( 9 ). Distinction of Aspergillus species within these sections is optimal with a polyphasic approach incorporating both morphological and molecular methods, as recommended by most experts ( 10 ).…”

Fungal rhinosinusitis (FRS) is a common problem worldwide, with an increasing burden in arid climate regions. Aspergillus species are the most common causative agents involved. In the present study, we investigated the prevalence, molecular characterization, and antifungal susceptibility of opportunists causing FRS in Sudan on the basis of strains collected over a period of 5 years. β-Tubulin and calmodulin sequencing were used for species identification, and antifungal susceptibility profiles were evaluated by the protocol of the European Committee on Antimicrobial Susceptibility Testing (EUCAST). Predominant species belonged to the Aspergillus flavus complex ( n = 244), A. terreus complex ( n = 16), A. fumigatus complex ( n = 7), and other fungi ( n = 17). Molecular identification of 94 strains of Aspergillus revealed the following species: A. flavus ( n = 88), A. terreus ( n = 1), A. citrinoterreus ( n = 2), A. fumigatus ( n = 1), A. caespitosus ( n = 1), and A. sydowii ( n = 1). Several A. flavus and an A. fumigatus isolates showed reduced susceptibility to azoles (minimum inhibitory concentrations above the clinical breakpoints or epidemiological cutoff values). Despite several mutations revealed in cyp51A of these isolates, none could be directly linked to azole resistance. Molecular identification of fungi causing FRS is useful to identify cryptic species and for epidemiologic studies. IMPORTANCE Fungal rhinosinusitis (FRS) is a significant clinical problem in arid regions. This study provides new insights into the prevalence, etiology, and antifungal susceptibility of FRS pathogens in Sudan, where the disease burden is high. Aspergillus species, particularly the A. flavus complex, were identified as the primary FRS pathogens in the region, with some evidence of antifungal resistance. The molecular identification of fungal species causing FRS is useful for detecting antifungal resistance, identifying cryptic species, and characterizing the epidemiology of the disease. The emergence of Azole resistance Aspergilli in Sudan highlights the need for continued surveillance and appropriate use of antifungal agents. These findings have important implications for clinical management, public health policy, and future research on FRS. Publishing this study in Microbiology Spectrum would enable other researchers and clinicians to build on these findings, ultimately improving the diagnosis, treatment, and prevention of FRS.
