“…Liu & Cai 9 reported a new species based on the morphological comparison and phylogenetic analysis of ITS and LSU sequences, which was the earliest application for the identification of Simplicillium species. Kondo et al 29 added the loci SSU in the analysis of Simplicillum species. Thus, three loci ( ITS , LSU and SSU ) were applied in the analysis of the relationship among Simplicillium species in this study.…”

Simplicillium species are commonly found from soil, seawater, rock surface, decayed wood, air and as symbiotic, endophytic, entomopathogenic and mycoparasitic fungi. Minority insect-associated species was reported. Simplicillium coccinellidae, S. hymenopterorum, S. neolepidopterorum and S. scarabaeoidea were introduced as the newly insect-associated species. The phylogenetic analyses of two combined datasets (LSU + RPB1 + TEF and SSU + ITS + LSU) revealed that S. coccinellidae and S. hymenopterorum were both nested in an independent clade. S. neolepidopterorum and S. scarabaeoidea have a close relationship with S. formicidae and S. lepidopterorum, respectively. S. neolepidopterorum can be easily distinguished from S. formicidae by ellipsoidal to cylindrical, solitary conidia which occasionally gather in short imbricate chains. S. scarabaeoidea could be easily distinguished from S. lepodopterorum by having longer phialides and larger conidia. Based on the morphological and phylogenetic conclusion, we determine the four newly generated isolates as new species of Simplicillium and a new combination is proposed in the genus Leptobacillium.

“…Zare and Gams ( 2001 ) summarized that solitary phialides, conidia adhering in globose, slimy heads or imbricate chains, and crystals commonly present in agar were the typical characteristics of Simplicillium . After that, numerous species were added to the genus (Liu and Cai, 2012 ; Nonaka et al, 2013 ; Gams, 2017 ; Zhang et al, 2017 ; Crous et al, 2018 ; Gomes et al, 2018 ; Chen et al, 2019 , 2021 ; Wei et al, 2019 ; Kondo et al, 2020 ; Wang et al, 2020 ; Leplat et al, 2021 ). However, based mainly on rDNA sequence analyses, several Simplicillium species ( S. wallacei, S. coffeanum A.A.M.…”

Multigene phylogeny, phylogenetic network, and morphological characterizations reveal four new arthropod-associated Simplicillium species and their evolutional relationship

et al. 2022

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.

Simplicillium pech-merlensis, a new fungal species isolated from the air of the Pech-Merle show cave

An original fungal strain has been recovered during an aerobiological survey in the Pech-Merle show cave (France). The use of multi-locus (ITS, LSU, SSU RPB1, RPB2 and TEF-1α) phylogenetic analysis of the strain by maximum likelihood and by Bayesian inference coupled with a morphological characterization allowed us to place it in the Simplicillium genus as Simplicillium pech-merlensis sp. nov. This new species seems morphologically close to S. calcicola and S. album, which were also first isolated from a cave habitat. This paper discusses the phylogenetic place of S. pech-merlensis and some other species in the genus Simplicillium.
