Absidia is ubiquitous and plays an important role in medicine and biotechnology. In the present study, nine new species were described from China in the genus Absidia, i.e. A. ampullacea, A. brunnea, A. chinensis, A. cinerea, A. digitata, A. oblongispora, A. sympodialis, A. varians, and A. virescens. Besides, two varieties A. cylindrospora var. nigra and A. spinosa var. biappendiculata were elevated to a specific rank as A. nigra comb. nov. and A. biappendiculata comb. nov., respectively. These new taxa were proposed based on a comprehensive investigation of morphological traits (such as shape and size of sporangia, sporangiospores and projections on columellae), physiological feature (maximum growth temperatures), and multi-locus sequences (including internal transcribed spacer, large subunit D1-D2 domains of nuclear ribosomal DNA, partial translation elongation factor 1 alpha gene and actin gene). All species mentioned above are illustrated, and an identification key to all the known species of Absidia in China is included.

Taxonomy and Phylogeny of Four New Species in Absidia (Cunninghamellaceae, Mucorales) From China

et al. 2021

View full text Add to dashboard Cite

Four new species within the genus Absidia, A. globospora, A. medulla, A. turgida, and A. zonata, are proposed based on a combination of morphological traits, physiological features, and molecular evidences. A. globospora is characterized by globose sporangiospores, a 1.0- to 3.5-μm-long papillary projection on columellae, and sympodial sporangiophores. A. medulla is characterized by cylindrical to oval sporangiospores, a 1.0- to 4.5-μm-long bacilliform projection on columellae, and spine-like rhizoids. A. turgida is characterized by variable sporangiospores, up to 9.5-μm-long clavate projections on columellae, and swollen top of the projection and inflated hyphae. A. zonata is characterized by cylindrical to oval sporangiospores, a 2.0- to 3.5-μm-long spinous projection on columellae, and as many as eight whorled sporangiophores. Phylogenetic analyses based on sequences of internal transcribed spacer rDNA and D1–D2 domains of LSU rDNA support the novelty of these four species within the Absidia. All new species are illustrated, and an identification key to all the known species of Absidia in China is included.

“…Soil fungi play key roles in nutrient cycling and the functioning of terrestrial ecosystems (Torsvik and Øvreås 2002;Frąc et al 2018;Peng et al 2020;Zhou et al 2020). To date, only a few fungal taxonomic studies are available from tropical forest soil (Sato et al 2015;Amma et al 2018;Cordeiro et al 2020;Lima et al 2020). Taxonomic studies on these groups are even scarcer in Southeast Asia despite the region harboring extraordinary genetic diversity (Amma et al 2018).…”

Mucor species are common fast-growing fungi found in soil. Two new species of Mucor and one new geographical record of M. nederlandicus were collected from northern Thailand and are described in this study. Evidence from morphophysiological data and phylogenetic analysis supports the introduction of the new taxa. Phylogenetic analysis based on the internal transcribed spacer (ITS) and large subunit of the nuclear ribosomal RNA (LSU) data showed that the new isolates cluster distinctly from other Mucor species with high or maximum bootstrap support. Mucor aseptatophorus is characterized by aseptate sporangiophores, globose columella, resistant and deliquescent sporangia, has sympodial, and monopodial branches and shows growth at 37 °C. It also differs from M. irregularis in having smaller sporangiospores, and larger sporangia. Mucor chiangraiensis has subglobose or slightly elongated globose columella, produces hyaline sporangiospores, and resistant and deliquescent sporangia. Furthermore, this species has wider sporangiophore, smaller sporangia and lower growth than M. nederlandicus. A detailed description of the species and illustrations are provided for the novel species.
