“…The information contained in the 18S-ITS-28S segment is generally su cient to delimit even closely related species (Krüger et al 2009) and numerous studies of AM fungal taxonomy were based solely on this barcoding region (e.g., Błaszkowski et 2020a, b). However, the concatenation of 18S-ITS-28S and RPB1 sequences was shown to increase the robustness of phylogenetic inference of AM fungi and revealed relationships unexposed when the single 18S-ITS-28S locus was analyzed (Błaszkowski et al 2021c). Unfortunately, so far only ca.…”

“…For the RPB1 sequences, we used the primer pairs RPB1_HS_A1a-RPB1_5R (1 st PCR) and RPB1_HS_A1a-RPB1_DR1210r (2 nd PCR) to amplify a ca. 2-kb fragment covering the majority of coding region (Stockinger et al 2014;Błaszkowski et al 2021c). The PCR conditions were the same as those for rDNA ampli cation, except that the cycling conditions of both PCRs were as follows: 98°C for 30s, 30 × (98°C for 10 s, 58°C for 10 s and 72°C for 2 min) and 72°C for 10 min.…”

Two glomoid spore-producing arbuscular mycorrhizal fungi were grown in single-species cultures established from soil-borne spores collected from high altitude (2,800 m a.s.l.) of Tibet Plateau, China.Phylogenetic analyses were performed with sequences of nuclear rDNA (spanning the partial small subunit, whole internal transcribed spacer, and partial large subunit segment = 18S-ITS-28S) and the largest subunit of RNA polymerase II (RPB1) gene. Morphological and phylogenetic analyses indicated that the two fungi are undescribed species of the genera Glomus and Dominikia. The rst fungus, described here as G. chinense sp. nov., formed spores singly and in loose clusters. The spores are orangeyellow to dark brown, globose, (47-)64(-93) µm diam. Dominikia gansuensis sp. nov. produced glomerocarps with pale yellow to yellow-brown, globose, (20-)47(-86) µm diam spores. Spore wall of both species consists of three layers. Both species differ clearly in morphology and phylogeny from their closest phylogenetic relatives, which are G. atlanticum and G. ibericum, and D. glomerocarpica, respectively.

A new order, Entrophosporales, and three new Entrophospora species in Glomeromycota

As a result of phylogenomic, phylogenetic, and morphological analyses of members of the genus Claroideoglomus, four potential new glomoid spore-producing species and Entrophospora infrequens, a new order, Entrophosporales, with one family, Entrophosporaceae (=Claroideoglomeraceae), was erected in the phylum Glomeromycota. The phylogenomic analyses recovered the Entrophosporales as sister to a clade formed by Diversisporales and Glomeraceae. The strongly conserved entrophosporoid morph of E. infrequens, provided with a newly designated epitype, was shown to represent a group of cryptic species with the potential to produce different glomoid morphs. Of the four potential new species, three enriched the Entrophosporales as new Entrophospora species, E. argentinensis, E. glacialis, and E. furrazolae, which originated from Argentina, Sweden, Oman, and Poland. The fourth fungus appeared to be a glomoid morph of the E. infrequens epitype. The physical association of the E. infrequens entrophosporoid and glomoid morphs was reported and illustrated here for the first time. The phylogenetic analyses, using nuc rDNA and rpb1 concatenated sequences, confirmed the previous conclusion that the genus Albahypha in the family Entrophosporaceae sensu Oehl et al. is an unsupported taxon. Finally, the descriptions of the Glomerales, Entrophosporaceae, and Entrophospora were emended and new nomenclatural combinations were introduced.

Morphological analyses of three glomoid spore-producing fungi suggested that two of them were undescribed species of Glomeraceae (phylum Glomeromycota), and the third differed slightly from Dominikia glomerocarpica and Epigeocarpum crypticum, recently described in Glomeraceae. The first two fungi originated from the Mediterranean Sea sand dunes of the Peloponnese, Greece, and the third was originally found in a tree plantation in Yokohama City, Japan. Phylogenetic analyses of sequences of the 45S nuc rDNA region and the RPB1 gene showed that (i) the three fungi belonged to Glomeraceae; (ii) the first two represented a new genus, here described as Complexispora gen. nov. with C. multistratosa sp. nov. and C. mediterranea sp. nov. and (iii) the third enlarged the monospecific genus Epigeocarpum, as E. japonicum sp. nov.
