... For example, within Cordycipitaceae, Lecanicillium and Simplicillium are found to infect plant pathogens (e.g. coffee rust fungus Hemileia vastatrix) and entomopathogens (Vandermeer et al. 2009, Baiswar et al. 2014, Wei et al. 2019. Pseudogibellula is found to grow directly on Ophiocordyceps, suggesting an apparent mycoparasitism (Araújo et al. 2020, Mongkolsamrit et al. 2021, and the genus Niveomyces has been recently proposed as a mycoparasite of Ophiocordyceps camponoti-floridani (Araújo et al. 2022). ...

Four new species of the genus Niveomyces are described from Thailand. They were found as mycoparasites on: Ophiocordyceps infecting flies ( Diptera ) for Niveomyces albus ; ants ( Hymenoptera ) for N. formicidarum ; and leafhoppers ( Hemiptera ) for N. hirsutellae and N. multisynnematus . A new genus, Pseudoniveomyces with two species: Pseudoniveo. blattae (type species), parasitic on Ophiocordyceps infecting cockroaches, and Pseudoniveo. arachnovorum , found on a spider egg sac, are also described. These fungi share a common feature which is a sporothrix-like asexual morph. Based on our molecular data, Sporothrix insectorum is shown to be affiliated to the genus Niveomyces , and thus a new combination N. insectorum comb. nov. is proposed. Niveomyces coronatus , N. formicidarum and N . insectorum formed the N. coronatus species complex found on ant-pathogenic Ophiocordyceps from different continents. Pseudoniveomyces species are distinguished from Niveomyces spp. based on the presence of fusoid macroconidia in culture and a red pigment diffused in the medium, resembling to Gibellula and Hevansia . The molecular phylogenetic analyses also confirmed its generic status. The host/substrates associated with the genera within Cordycipitaceae were mapped onto the phylogeny to demonstrate that mycoparasitism also evolved independently multiple times in this family.

A fungal strain (JC-1) of Simplicillium was isolated from a pod of oilseed rape (Brassica napus) infested with the blackleg pathogen Leptosphaeria biglobosa. This study was done to clarify its taxonomic identity using morphological and molecular approaches, to characterize its antifungal activity through bioassays and genome-based identification of antifungal metabolites, and to determine its efficacy in inducing systemic resistance (ISR) in oilseed rape. The results showed that JC-1 belongs to Simplicillium lamellicola. It displayed a strong antagonistic relationship with L. biglobosa, Botrytis cinerea (gray mold) and Sclerotinia sclerotiorum (stem rot). The cultural filtrates of JC-1 showed a high efficacy in suppressing infection by S. sclerotiorum on detached leaves of oilseed rape. Genome analysis indicated that JC-1 has the capability of producing multiple antifungal metabolites, including aureobasidin A1, squalestatin S1 and verlamelin. Inoculation of JC-1 on seeds of oilseed rape caused a suppressive effect on infection by L. biglobosa on the cotyledons of the resulting seedlings, suggesting that JC-1 can trigger ISR. Endophytic growth, accumulation of anthocyanins, up-regulated expression of CHI (for chalcone isomerase) and PR1 (for pathogenesis-related protein 1), and down-regulated expression of NECD3 (for 9-cis-epoxycarotenoid dioxygenase) were detected to be associated with the ISR. This study provided new insights into the biocontrol potential and modes of action of S. lamellicola.

Simplicillium species are widely distributed and commonly found on various substrates. A minority of species are associated with arthropods. A spider-associated species Simplicillium araneae , and three insect-associated species, Simplicillium coleopterorum, Simplicillium guizhouense , and Simplicillium larvatum , are proposed as novel species based on a multi-locus phylogenetic analysis and morphological characteristics. These Simplicillium species completely fit the nutritional model of Hypocreales fungi and could be used as a model to study their evolutionary relationship. A phylogenetic network analysis based on ITS sequences suggests that a host jump was common among Simplicillium species, and S. araneae may have originally come from an insect host and then jumped to a spider host. However, the evolutionary relationship of S. coleopterorum, S. guizhouense , and S. larvatum was not clear in the phylogenetic network and more sequencing information should be added to the network. In addition, strain CBS 101267 was identified as Simplicillium subtropicum .
... The fungus S. lanosoniveum isolated from sori of soybean rust (Phakopsora pachyrhizi) on soybean was found as a mycoparasite on the soybean-rust pathogen Phakopsora pachyrhizi (Gauthier et al. 2014;Ward et al. 2011Ward et al. , 2012. S. lanosoniveum strains isolated in India show hyperparasitism on Aecidium elaneagni-latifoliae, which causes rust on Elaeagnus latifolia (Baiswar et al. 2014). S. lanosoniveum strains isolated from fruiting bodies generated on a pine cone in Korea have entomopathogenicity and can be used in biological control of insects (Lim et al. 2014). ...
A previously unknown association between Plasmopara viticola, the causal pathogen of grape downy mildew, and the mycoparasite strain F2 is described in this paper. F2 could be consistently isolated from the mildew of diseased spots on grape leaves of Kyoho ( Vitis labrusca × V. vinifera cv. Kyoho) infected with P. viticola but not from the surfaces of healthy grape leaves or within lesions of other diseases. It was observed that strain F2 was capable of coiling around sporangiophores and sporangia of P. viticola under a microscope, causing hyphae deformation, decreasing the pathogen growth, and reducing the number of sporangia. This fungal strain was identified as Simplicillium lanosoniveum on the basis of morphological characterizations and 28S rDNA sequencing. To our knowledge, this is the first report of S. lanosoniveum with hyperparasitic characteristics on P. viticola, and the hyperparasite has potential application in the control of grape downy mildew.

... As a biological control agent for soybean rust pathogen Phakopsora pachyrhizi, S. lanosoniveum was found to reduce the development of new uredinia and the germination rate of urediniospores (Ward et al., 2012). Baiswar et al. (2014) found that S. lanosoniveum also parasitizes rust pustules on Elaeagnus latifolia. Thus, biocontrol strategies have the potential for control of rusts. ...
Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most serious threats to wheat production worldwide. Changes of Pst virulence may circumvent resistance in wheat varieties, and application of fungicides may cause environmental problems. Parasites of Pst can be used to develop biological agents for environmentally friendly control of this fungal disease. Here, we report a hyperparasitic fungus isolated from Pst and identified it as Simplicillium obclavatum through molecular and morphological characterizations. We demonstrated that inoculation of Pst-infected wheat leaves with S. obclavatum reduced the production and germination rate of Pst urediniospores. Therefore, S. obclavatum has the potential to be developed into a biological control agent for managing wheat stripe rust.
... Simplicillium lanosoniveum has been frequently reported as a hyperparasite of rust and plant pathogenic fungi. Therefore, this species has a high potential of being a natural source of microbial agents against microbiological diseases in commercial agriculture (Baiswar et al. 2014;Berlanga-Padilla et al. 2018). At first, we included all available sequences of S. lanosoniveum from GenBank in the individual gene tree. ...
Simplicillium species have a wide host range and an extensive distribution. Some species are associated with rusts, as well as other plant pathogenic fungi and play an important role in biological control. In this study, two specimens of Simplicillium were collected from Chiang Mai Province, Thailand. Simplicillium formicae sp. nov. was isolated from an infected ant and S. lanosoniveum from Ophiocordyceps unilateralis which is a new host record. Species were initially identified using ITS gene sequences and confirmed using morphology coupled with phylogenetic analyses of a combined nrLSU, nrSSU, TEF and RPB1 dataset. Simplicillium formicae differs from other species in the genus by the presence of flask-shaped synnemata and phialides with intercalary nodes. Simplicillium lanosoniveum resembles other collections of the species by its completely solitary, tapering phialides and globose to ellipsoidal conidia which adhere in a slimly head. A key to species of Simplicillium is also provided.
... The genus is characterized with its complete lack of verticillate branching; mostly solitary phialides, which are discrete, aculeate and narrow and arise from aerial hyphae; conidia short-ellipsoidal to suglobose or obclavate, and adhering in globose heads or imbricate chains (Zare and Gams 2001). The members of Simplicillium are fungicolous and occur on various substrata (Zare and Gams 2001;Chen et al. 2008;Baiswar et al. 2014;Gauthier et al. 2014;Gomes et al. 2018). Furthermore, Zare and Gams (2001) introduced three additional species, viz., S. lamellicola (F. ...
... Simplicillium lamellicola belongs to the hyperparasite fungi (Shin et al. 2017). Simplicillium lanosoniveum was reported as both an endophytic and hyperparasite fungi (Baiswar et al. 2014). It has been reported that Simplicillium is pathogenic to insects. ...
In this paper, we introduce three new species of Simplicillium , viz. S. cicadellidae , S. formicidae and S. lepidopterorum , which were isolated from an infected leafhopper, ant and carpenterworm, respectively. Morphological comparisons and phylogenetic analyses based on multigene datasets (LSU+RPB1+RPB2+TEF and ITS+LSU) support the establishment of the three new species. Simplicillium cicadellidae was distinguished from other species in morphological characteristics by having smaller phialides and ellipsoidal conidia, and lacking octahedral crystals. The reverse of colonies were yellowish (#FFBF00), especially in the middle, and radially sulcate. Simplicillium formicidae was morphologically distinguished from other by having longer phialides and filiform to fusoid conidia, and by lacking octahedral crystals. Simplicillium lepidopterorum was morphologically distinguished from other species by having smaller, ellipsoidal to fusiform conidia, and by lacking octahedral crystals. The reverse of the colony was pale white. The three new species are likely to be nourished by plant to animal (especially insect) nutrients based on the evolutionary pattern of the Hypocreales, and they are described herein as being clearly distinct from other species in Simplicillium .
