A new combination, Clinoconidium inouyei, is proposed to accommodate Uredo inouyei (syn. Ustilago inouyei, Melanopsichium inouyei, Ustilago machili) from Japan, producing galls on shoot buds of Machilus japonica (Lauraceae). This taxonomic treatment is based on observations of gastroid sporulation in peripheral lacunae of the host galls and basidiospore morphology. This is also supported by phylogenetic analyses with LSU and ITS regions of rDNA. This species is morphologically and phylogenetically similar to C. onumae producing galls on shoot buds of Cinnamomum tenuifolium reported from Japan, but has larger basidiospores.

This taxonomic treatment is based on observations of gastroid sporulation in peripheral lacunae of the host galls and basidiospore morphology. This species is morphologically and phylogenetically similar to Cl. cinnamomi producing galls on fruits of Ci. burmannii, reported from Taiwan, but differs by having larger basidiospores and different morphology of the gall structures, and by affecting different plant organs.

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.

Abstract During a survey of polypores in the montane forest of the Ôbo de São Tomé National Park, in the western African, equatorial island of São Tomé, a specimen that was, a priori, related to Fomitopsis, based on the gross morphology of the basidiome and a brown rot, showed deviating features including subglobose basidiospores with a large gutta, what pointed toward Niveoporofomes. Phylogenetic inferences based on multiple loci dataset (ITS-nLSU-nSSU-tef1-rpb2) confirmed these affinities, and Niveoporofomes oboensis is described as new. The species is compared to Fomitopsis widdringtoniae, known from southeast Africa, which is characterized also by subglobose basidiospores; hence, the new combination N. widdringtoniae is proposed. The new combination Niveoporofomes globosporus (basionym Trametes globospora) is also proposed based on phylogenetic analyses. A key to the species of Fomitopsis, Niveoporofomes, Rhodofomes, and Rhodofomitopsis in Tropical Africa is presented.

The distinction of the perennial Aristida coerulescens from the annual A. adscensionis and its taxonomic treatment has been subject of long discussions. We here include accessions from the Mediterranean and Macaronesia for molecular phylogenetic analyses and conducted a morphometric analysis. A lineage of A. adscensionis, A. coerulescens and A. effusa is well supported in phylogenetic trees. Moreover, a group of Mediterranean, Macaronesia and Arabian A. coerulescens and A. adscensionis is revealed where both taxa are intermingled. A morphological analysis of traditionally used spikelet characters did not indicate a clear separation of both taxa. We therefore conclude that A. coerulescens should best be treated as synonym of A. adscensionis. The differential character of annual and perennial life forms seems to be plastic in this taxon indicating rapid shifts between these two strategies.

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.

Stenomitos is a recently established cyanobacterial genus, some species of which appear to be cryptic. Here we describe two new species in this genus, Stenomitos kolaensis sp. nov. isolated from the Al-Fe humic podzols of a boreal forest near Nikel town, Murmansk region, Russia and S. hiloensis sp. nov. isolated from a basaltic seep wall on Akeola Road, Hilo, Hawaii, USA. Phylogenetic analyses were conducted on the 16S and 16S-23S ITS rRNA gene regions using Bayesian Inference, and Maximum Likelihood. Phylogenetic analysis of the 16S-23S ITS rRNA region resulted in both S. kolaensis and S. hiloensis forming separate clades from other Stenomitos lineages. Antarctic strains of Stenomitos frigidus (previously reported as “Leptolyngbya frigida”) show that species to be polyphyletic and in need of revision. The structure of the conserved ITS regions (Box-B, D1-D1ʹ, V2 and V3 helices) provided support for separation of the species, and the p-distances among aligned ITS regions further confirmed that a number of species exist within the genus. S. kolaensis and S. hiloensis can be distinguished from other described Stenomitos species (S. rutilans and S. tremulus) by their geographical distribution, habitat preference, 16S rRNA phylogeny, and differences in the secondary structure of the 16S-23S ITS region.

Phyllagathis phamhoangii, a species from Vietnam, was originally described in Phyllagathis based on its resemblance to P. nanakorniana and P. subrotunda in habit, rhizome morphology and leaf shape. However, its overall morphology, mainly stamen and capsule morphology, corresponds better with Fordiophyton indicating questionable generic affiliation. We included molecular (nrITS) and anatomical (crystal form) evidences to resolve the generic affiliation of P. phamhoangii. Our phylogenetic analyses recovered P. phamhoangii inside Fordiophyton and P. nanakorniana and P. subrotunda inside the Kerriothyrsus clade. The Fordiophyton clade is characterized by the presence of raphides, while the Kerriothyrsus clade is characterized by druses. Based on these evidences, P. phamhoangii is herein transferred to Fordiophyton, resulting in a new combination F. phamhoangii. It is morphologically similar to F. peperomiifolium but differs from the latter in the leaf blade with shortly acuminate to acuminate apex (vs. broadly acute), hypanthium 4-ridged (vs. not ridged), and connectives of shorter stamens dorsally spurred (vs. not spurred).

Clavularia amboinensis Burchardt, a species described as possessing simple, pinnule-less tentacles (a fact refuted by later authors) is confirmed to be as described and is transferred as a new combination to Acrossota Bourne — a genus dismissed until now by a number of authors. The species is compared to recently collected material with live photographs. A second new genus and species, Knopia octocontacanalis, is also described. This taxon resembles Acrossota in general form, but has tentacles where the pinnules appear as though they are fused side to side along the tentacles’ lateral margins. Preliminary phylogenetic analyses of two mitochondrial genes support placement of Knopia in Clavulariidae and retention of genus Acrossota in Bourne’s unrecognised family Acrossotidae.

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.

Pimelea Banks & Sol. ex Gaertn. is a genus of flowering plants comprising an estimated 90 species in Australia and ~35 species in New Zealand. The genus is economically important, with the inflorescences of some species having floricultural applications, and the presence of toxic compounds in several species proving poisonous to livestock. Pimelea grows in a variety of habitats ranging from arid to alpine, suggesting a complicated biogeographic history. The relationships within Pimelea remain largely uncertain, despite previous attempts at clarification using molecular phylogenetics. However, it is clear that Pimelea is closely related to Thecanthes Wikstr., with the two genera comprising the subtribe Pimeleinae. We used Bayesian and maximum-likelihood phylogenetic analyses of four plastid markers (matK, rbcL, rps16, trnL–F) and one nuclear ribosomal marker (ITS) to examine the evolutionary relationships within Pimeleinae. We found strong support for the monophyly of Pimeleinae but, similar to previous studies, Pimelea was paraphyletic with respect to Thecanthes. Our results also indicated that P. longiflora R.Br. subsp. longiflora and P. longiflora subsp. eyrei (F.Muell.) Rye are best considered as distinct species. Therefore, we reduce Thecanthes to synonymy with Pimelea, making the necessary new combination Pimelea filifolia (Rye) C.S.P.Foster et M.J.Henwood (previously Thecanthes filifolia Rye), and also reinstate Pimelea eyrei F.Muell.
