Unveiling species diversity within the family Conidiobolaceae (Entomophthorales) in China: Descriptions of two new species and reassessment of the taxonomic position of Conidioboluspolyspermus. MycoKeys 2024; 105:203-216. [PMID: 38818111 PMCID: PMC11137373 DOI: 10.3897/mycokeys.105.117871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 04/30/2024] [Indexed: 06/01/2024] Open
Abstract
In the present study, two new Conidiobolus s.s. species were described relying on the morphological studies and phylogenetic analysis utilizing nuclear large subunit of rDNA (nucLSU), mitochondrial small subunit of rDNA (mtSSU), and elongation-factor-like gene (EFL) sequences. Conidiobolusjiangxiensissp. nov. is distinguished by its short primary conidiophores, a feature not commonly observed in other Conidiobolus s.s. species. Conversely, Conidiobolusmarcoconidiussp. nov. is characterized by larger primary conidia and the emergence of 2-5 secondary conidia from each branched secondary conidiophores. Additionally, the taxonomic reassessment of C.polyspermus confirms its distinct status within the genus Conidiobolus s.s. Moreover, molecular analyses, incorporating the nucLSU, mtSSU, and EFL sequences, provide robust support for the phylogenetic placement of the two newly described species and the taxonomic identity of C.polyspermus. This investigation contributes valuable insights into the species diversity of Conidiobolaceae in China, enhancing our understanding of the taxonomy within this fungal family.

Three New Species of Gongronella ( Cunninghamellaceae, Mucorales) from Soil in Hainan, China Based on Morphology and Molecular Phylogeny. J Fungi (Basel) 2023; 9:1182. [PMID: 38132783 PMCID: PMC10744856 DOI: 10.3390/jof9121182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 12/07/2023] [Accepted: 12/08/2023] [Indexed: 12/23/2023] Open
Abstract
The genus Gongronella is important in agriculture and industry by secreting various natural bioactive metabolites such as chitosanases and organic acids. During the most recent 8 years, a total of 14 new species have been described, remarkably enriching the diversity of this genus. In this study, we added three more new species to this valuable genus, based on a combination of morphological traits and phylogenetic information. Six strains of the genus Gongronella were isolated from soil collected in Hainan Province, China. Phylogenetic analyses of ITS and LSU rDNA sequences grouped these strains into three independent clades. According to their unique morphological characteristics, they were classified as G. multiramosa sp. nov., G. qichaensis sp. nov. and G. oleae sp. nov. The G. multiramosa was characterized by multiple branched sporangiophores and was closely related to G. pedratalhadensis. The G. qichaensis was characterized by obscure collars and closely related to G. butleri, G. hydei and G. banzhaoae. The G. oleae was characterized by the presence of oil droplets in the sporangiospores and was closely related to G. chlamydospora and G. multispora. Their descriptions and illustrations were provided, and their differences from morphological allies and phylogenetic-related species are discussed.

Abstract
The genus Conidiobolus s.s. (Conidiobolaceae, Entomophthorales) has been delimited to accommodate members that produce microspores. Herein, morphological studies, combined with phylogenetic analysis based on the nuclear large subunit of rDNA (nucLSU), the mitochondrial small subunit of rDNA (mtSSU), and the elongation-factor-like gene (EFL) revealed two Conidiobolus s.s. species isolated from plant debris in China. Conidioboluslongiconidiophorussp. nov. is mainly characterised by its long primary conidiophores, while Conidioboluspolysporussp. nov. is diagnosed by 2-3 primary conidia arising from branched primary conidiophores. Phylogenetically, the former is grouped into a separate clade, while the latter is closely related to C.incongruus, but is morphologically distinguished by its larger primary conidia and branched conidiophores.

Abstract
Although species of Absidia are known to be ubiquitous in soil, animal dung, and insect and plant debris, the species diversity of the genus and their ecological habitats have not been sufficiently investigated. In this study, we describe five new species of Absidia from forest and grassland soils in southwestern China, with support provided by phylogenetic, morphological, and physiological evidence. The species diversity and ecological habitat of Absidia are summarized. Currently, 22 species are recorded in China, which mainly occur in soil, especially in tropical and subtropical forests and mountains. An updated key to the species of Absidia in China is also provided herein. This is the first overview of the Absidia ecological habitat.

Abstract
Species of Absidia are distributed widely in the environment, while their diversity is insufficiently studied. Three new species, A. frigida, A. gemella and A. longissima, are proposed herein from Xinjiang and Yunnan in China based on phylogenetic, morphological and physiological evidence. According to maximum likelihood (ML), maximum parsimony (MP) and Bayesian inference (BI) analyses, the phylogenetical results suggest that A. frigida, A. gemella and A. longissima are closely related to A. psychrophilia, A. turgida and A. zonata and A. koreana, respectively, based on ITS and LSU rDNA sequences. Absidia frigida is characterized by a lower growth temperature, which does not grow above 24 °C. It differs from A. psychrophilia by sporangiophores, sporangia, columellae, collars and projections. Absidia gemella is distinguished from A. turgida by hypha, sporangiospores, sporangia, projections and sporangiophores. Absidia longissima is discriminated from A. zonata and A. koreana by sporangiophores, columellae and collars. The three new species are described and illustrated in this article.

Abstract
The fungal genus Conidiobolus sensu lato was delimited into four genera based on morphology and phylogeny. However, the taxonomic placement of C.parvus has not been determined until now. Here, we show that C.parvus belongs to a distinct lineage based on mitochondrial (mtSSU) and nuclear (TEF1 and nrLSU) phylogenetic analyses. Phylogenetic analyses further revealed a new species as sister to C.parvus. We identified a synapomorphy uniting these lineages (azygospore production) that was not observed in other allied genera of the family Ancylistaceae, and erected a new genus Azygosporusgen. nov. for this monophyletic group, with a new combination, A.parvuscomb. nov. as the type species. Within Azygosporus, the novel species A.macropapillatussp. nov. was introduced from China based on morphological characteristics and molecular evidence, which is characterized by its prominent basal papilla, in comparison to other closely related species, measuring 7.5–10.0×5.0–10.0 µm. Our study resolved the phylogenetic placement of C.parvus and improved the taxonomic system of the Ancylistaceae family.

Abstract
The genus Conidiobolus s.s. was newly delimited from Conidiobolus s.l. In order to gain insight into its mitochondrial genetic background, this study sequenced six mitochondrial genomes of the genus Conidiobolus s.s. These mitogenomes were all composed of circular DNA molecules, ranging from 29,253 to 48,417 bp in size and from 26.61 to 27.90% in GC content. The order and direction for 14 core protein-coding genes (PCGs) were identical, except for the atp8 gene lost in Conidiobolus chlamydosporus, Conidiobolus polyspermus, and Conidiobolus polytocus, and rearranged in the other Conidiobolus s.s. species. Besides, the atp8 gene split the cox1 gene in Conidiobolus taihushanensis. Phylogenomic analysis based on the 14 core PCGs confirmed that all Conidiobolus s.s. species formed a monophyly in the Entomophthoromycotina lineage. The number and length of introns were the main factors contributing to mitogenomic size, and deep variations and potential transfer were detected in introns. In addition, gene transfer occurred between the mitochondrial and nuclear genomes. This study promoted the understanding of the evolution and phylogeny of the Conidiobolus s.s. genus.

Abstract
The species within the family Cunninghamellaceae are widely distributed and produce important metabolites. Morphological studies along with a molecular phylogeny based on the internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal DNA revealed two new species in this family from soils in China, that is, Absidia ovalispora sp. nov. and Cunninghamella globospora sp. nov. The former is phylogenetically closely related to Absidia koreana, but morphologically differs in sporangiospores, sporangia, sporangiophores, columellae, collars, and rhizoids. The latter is phylogenetically closely related to Cunninghamella intermedia, but morphologically differs in sporangiola and colonies. They were described and illustrated.
