Morphological Species

Unlike most phialide-producing fungi that liberate a multiplicity of conidia from each conidiogenous cell, only single conidia are formed on phialide-like conidiogenous cells in Aphanocladium, Verticimonosporium, and some species of Sibirina. A group of isolates obtained from soil of native Artemisia tridentata (sagebrush) grassland in Wyoming and from desert soil in Iraq is compared with these genera and classified as a fourth genus, Stanjemonium, honouring Stanley J. Hughes. Phylogenetic analyses of partial nuclear small- (18S) and large-subunit (28S) rDNA sequences indicate that Stanjemonium spp. form a monophyletic group with Emericellopsis. Sequences from the nuclear 18S and 28S rDNA were too conserved to resolve morphological species of Stanjemonium; however, phylogenetic analysis of b-tubulin and translation elongation factor 1a gene exons and introns resolved all species distinguished morphologically. Numerous conidiogenous cells or denticles are scattered along the cells of aerial hyphae in Aphanocladium and Stanjemonium spp., very rapidly collapsing into denticles in the former, somewhat more persistent and leaving broad scars in the latter. In Cladobotryum-Sibirina and Verticimonosporium spp., conidiogenous cells are discrete in terminal and intercalary whorls; phialides of the latter taxon are particularly swollen. The taxonomy of Aphanocladium is not yet resolved. Two species are recognized in Verticimonosporium. Three new species of Stanjemonium are described, and one new combination from Aphanocladium is proposed, along with one new species of Cladobotryum.Key words: Aphanocladium, Cladobotryum, conidiogenesis, hyphomycetes, molecular phylogeny, phialide, Stanjemonium, systematics, Verticimonosporium.

Ornamental Shrub

A powdery mildew (Erysiphales) has recently been collected on leaves of an ornamental shrub Deutziaparviflora in Baihua Mountain, Beijing, China. Microscopic examination of the chasmothecia suggested a species belonging to Erysiphesect.Erysiphe, above all due to mycelioid chasmothecial appendages, although circinate apices of the appendages were rather in favour of Erysiphesect.Uncinula, which is a fairly rare combination of appendage characteristics in Erysiphe. Phylogenetic analyses of ITS and 28S rDNA sequences demonstrated that the two examined powdery mildew collections on D.parviflora clustered together as an independent lineage within Erysiphe with 100% bootstrap support, representing a species of its own, which is phylogenetically allied to, but clearly distinct from Erysiphedeutziae and, in addition, morphologically quite different from all known Erysiphe species on hosts belonging to the Hydrangeaceae. The new species on D.parviflora is described as Erysiphedeutziicola.

Molecular Phylogenetic

Taxonomic and phylogenetic studies of Chlorophyllum were carried out on the basis of morphological differences and molecular phylogenetic analyses. Based on the phylogeny inferred from the internal transcribed spacer (ITS), the partial large subunit nuclear ribosomal DNA (nrLSU), the second largest subunit of RNA polymerase II (rpb2) and translation elongation factor 1-α (tef1) sequences, six well-supported clades and 17 phylogenetic species are recognised. Within this phylogenetic framework and considering the diagnostic morphological characters, two new species, C.africanum and C.palaeotropicum, are described. In addition, a new infrageneric classification of Chlorophyllum is proposed, in which the genus is divided into six sections. One new combination is also made. This study provides a robust basis for a more detailed investigation of diversity and biogeography of Chlorophyllum.

A New Species

A new species of Mucor, isolated from the surface of Lycorma delicatula collected at Cheongyang in the Chungnam Province of Korea, is described and compared with morphologically similar taxa. The phylogenetic analysis of the internal transcribed spacer (ITS) and the large subunit (28S) rDNA sequences revealed that this isolate is closely related to M. orantomantidis and M. guilliermondii. However, the new isolate differs from those by having larger sporangia (24.5–125 × 23.5–120 µm), rhizoid-like structures, and production of secondary sporangia from vesicles outside of the original sporangium. Here, this novel fungal taxon is proposed as Mucor cheongyangensis sp. nov.

Favolaschia calocera was originally described from Madagascar, and reported to have a worldwide distribution. In the current study, samples of the Favolaschia calocera from Central America, Australia, China, Kenya, Italy, New Zealand, and Thailand were analyzed by using both morphological and molecular methods. Phylogenetic analyses were based on the internal transcribed spacer (ITS) dataset, and the combined five-locus dataset of ITS, large subunit nuclear ribosomal RNA gene (nLSU), the small subunit mitochondrial rRNA gene (mt-SSU), the small subunit of nuclear ribosomal RNA gene (nu-SSU), and the translation elongation factor 1α (TEF1). Our study proves that Favolaschia calocera is a species complex, and six species are recognized in the complex including four new species. Three new species F. brevibasidiata, F. brevistipitata, and F. longistipitata from China; and one new species F. minutissima from Asia. In addition, Favolaschia claudopus (Singer) Q.Y. Zhang & C. Dai, earlier treated as a variety of Favolaschia calocera R. Heim, were raised to species rank. Illustrated descriptions of these five new taxa are given. An identification key and a comparison of the characteristics of species in the Favolaschia calocera complex are provided.

Three New Species

Akanthomyces is a genus of invertebrate-pathogenic fungi from the family Cordycipitaceae (Ascomycota, Hypocreales). Its species occurs on two different types of hosts, spiders and insects, and in the latter case specifically Lepidoptera adults. Three new species of Akanthomyces, A. noctuidarum, A. pyralidarum, and A. tortricidarum occurring on adult moths from Thailand are proposed based on the differences of their morphological characteristics and molecular data. Phylogenetic analyses using a combined dataset, including the internal transcribed spacer regions, the large subunit of the ribosomal DNA, translation elongation factor 1-α, the largest subunit of RNA polymerase II, and the second largest subunit of RNA polymerase II, support the delimitation of these new species in Akanthomyces.

Species in the genus Tomentella are distributed throughout the temperate and tropical regions worldwide, but few studies associated with the taxonomy and phylogeny of this genus had been reported from Northwest China. In this paper, molecular phylogenetic analyses of the nuclear ribosomal ITS (internal transcribed spacer: ITS1-5.8S-ITS2) and LSU (large subunit: 28S) sequences combined with morphological characteristics identified three new species from Xinjiang Autonomous Region in Northwest China, which were named T. aurantispora, T. kanasensis, and T. schrenkiana. Similar macromorphological and anatomical characteristics are shared by these new species: arachnoid basidiocarps; byssoid sterile margins; utriform basidia with a clamp connection at the base; the absence of rhizomorphs and cystidia; and slightly thick-walled, subglobose to globose basidiospores. Among these new species, the color of the hymenophoral surface, the size of the basidiospores, and some other features can be used for species delimitation. The new species and closely related species in the phylogenetic tree were discussed, and a key to the identified species of Tomentella from China was provided.

In this study, two new brackish-water species of Macrostomum (M. shenda n. sp. and M. spiriger n. sp.) collected from Shenzhen, China, were described based on morphological, histological, and molecular phylogenetic analyses. Macrostomum shenda n. sp. differs from its congeners in the oblique and non-thickening distal opening of its narrow funnel-shaped stylet. In addition, its sperm have neither bristles nor brush, and are surrounded by an undulating membrane in the mid-body region. In M. spiriger n. sp., the stylet is spirally twisted. Its reproductive apparatus has a seminal bursal pore opening exteriorly. Results of the 18S and 28S rDNA phylogenetic analyses also support the establishments of these two new species. Moreover, the 18S and 28S rDNA sequences of some species within Macrostomum in previous studies have been revised to avoid ambiguity, while Macrostomum dongyuanensis Wang & Sun, 2015 was re-identified as a new record of M. quiritium Kolasa, 1973 from China.

Eriophyoid Mites

We describe two new species and report new occurrences for six species of eriophyid mites (Eriophyoidea: Eriophyidae) in Crimea: Abacarus denticulifer n. sp. from Agropyron cristatum (L.) Gaertn. (Poaceae), Aceria aculiformis Sukhareva 1986 from Melica ciliata L. (Poaceae), Aceria peucedani (Canestrini 1891) from Seseli tortuosum L. (Apiaceae), Anthocoptes recki (Bagdasarian 1972) n. comb. (from Tegonotus) from Pistacia atlantica subsp. mutica (Fisch. & C.A. Mey.) (Anacardiaceae), Epitrimerus inulae Farkas 1963 from Inula germanica L. (Asteraceae), Phyllocoptes sanctus n. sp. from Potentilla recta subsp. obscura (Willd.) (Rosaceae), Phyllocoptes bilobospinosus Chetverikov 2019 (in Chetverikov et al. 2019) from Tamarix spp. (Tamaricaceae), Tegoprionus dentatus (Nalepa 1891) from Galium verum L. (Rubiaceae). For an Indian phyllocoptine mite species associated with Apluda mutica L. (Poaceae), a new combination was proposed: Abacarus muticus (Sur & Chakrabarti 2017) n. comb. (from Mesalox). Mitochondrial COI and D2 28S rDNA sequences of three phyllocoptine species from Crimea were obtained: A. denticulifer n. sp. (GenBank accession numbers MK415989 and MK408623), P. bilobospinosus (MK408624), and P. sanctus n. sp. (MK415988 and MK408622). Comparison of all COI and D2 28S sequences of Eriophyoidea from GenBank showed that sequences JF920111 and JF920110 Aceria tulipae are identical to JF920101 Aceria tosichella, and D2 28S sequence KP297379 Tegolophus sp. is identical to KM111079 Shevtchenkella sp., which indicates either one or more misidentifications or sample contamination. Molecular phylogenetic analyses (a) confirmed the morphology-based assignment of A. denticulifer n. sp. to the Abacarus hystrix s.l. species complex, (b) supported the monophyly of Abacarus hystrix s.l., (c) revealed that the genera Phyllocoptes, Epitrimerus, and Calepitrimerus are paraphyletic, and (d) indicated that Phyllocoptini (including P. sanctus n. sp.), which are associated with Rosaceae and Caprifoliaceae, are monophyletic. The position of P. bilobospinosus was uncertain in all analyses. Based on the results of our study, it is recommended that descriptions of new species in large, putatively paraphyletic genera of Eriophyoidea include comparisons with mite species associated with the same plant family. Our work also provides new evidence that a species in a large complex of cryptic species could have evolved a distinct morphology if it is associated with an endemic plant host restricted to a geographically isolated area.

Based on the results of morphological and molecular phylogenetic analyses of newly collected material, we reinstate thesoft coral genus Eunephthya Verrill, 1869 for a group of species endemic to South Africa. Eunephthya is morphologicallyand phylogenetically distinct from the zooxanthellate, tropical genus Capnella Gray, 1869 with which it had been synon-ymized. In Eunephthya the polyp sclerites include unilaterally spinose or leaf spindles, and the sclerites of the stalk surfaceand interior (when present) are small radiates and spheroids. In contrast, C. imbricata, the type species of Capnella, hasleaf clubs and leaf-capstans in the polyps and stalk surface, and large ovals and irregular forms in the interior. We describefour new species of Eunephthya from Algoa Bay, South Africa—E. celata, E. ericius, E. granulata, and E. shirleyae— and propose a new combination, E. susanae.Keywords.

Summary Mexicana rubra sp. nov. and Encotyllabe cf. spari are described from the gills of the marine fish Orthopristis ruber (Haemulidae) caught off Rio de Janeiro, Brazil. Morphological, ultrastructural and genetic data are provided. The main diagnostic features of this new species of ectoparasite are a posteriorly bipartite testis, a ventral bar with three deep bowed projections and a dorsal bar with two deep, conspicuous, antero-lateral indentations. Genetic data on Mexicana rubra sp. nov. are based on the ITS1, 5.8S and partial 18S and 28S rDNA. This is the sixth known species of Mexicana Caballero & Bravo-Hollis, 1959, a key to which is also presented. Encotyllabe cf. spari Yamaguti, 1934 is described from the same host, with new ultrastructural data and new partial 18S and 28S rDNA sequences. A phylogenetic analysis based on partial 18S and 28S sequences is undertaken for both species.
