AbstractAs a result of the research carried out in Lakes Duszatyńskie and the Olchowaty stream, a new European site with Geissleria declivis (Hust.) Lange-Bert. was found — a new species for Poland. The highest abundance of G. declivis has been observed on sandy substrate and small stones in the littoral zone of the Upper Lake during the spring season. The species occurred together with Achnanthidium minutissimum (Kütz.) Czarn. var. minutissimum, A. catenatum (Bily & Marvan), Fragilaria leptostauron (Ehrenb.) Hust. var. leptostauron and F. pinnata Ehrenb. var. pinnata. Our observations revealed that G. declivis develops in lentic water bodies with medium organic matter content and neutral pH. The species seems to prefer mesotrophic waters with low to medium electrolyte content and oligosaprobous. The species morphology and identity is documented in a series of light microscopic (LM) images and for the first time under a scanning electron microscope (SEM).

A new species, Stemonitis planusis, was collected in Shennongjia National Nature Reserve, Hubei Province, China; it has larger sporocarps that usually end in a plane at the apex of the sporotheca, and its capillitia are expanded at the axils. Additionally, Elaeomyxa Hagelst. was documented for the first time in China; E. miyazakiensis (Emoto) Hagelst. was identified based on material collected from Dasu Forest, Fushun City, Liaoning Province, China. This newly recorded species is characterised by the wax in its stalk, peridium, and capillitium, and spores (approximately 7–8 μm in diam.) marked with rows of warts. A description and scanning electron micrographs of the collected Elaeomyxa and Stemonitis are provided. All specimens are deposited in the Herbarium of the Mycological Institute of Jilin Agricultural University (HMJAU), Changchun, China.

The E. ovina group of species is proposed here to include Edessa ovina Dallas, 1851 from Trinidad and Tobago, Colombia, Paraguay, Brazil, Argentina (new records) and Guyana; E. impura Bergroth, 1891 from Brazil and Argentina (new record); E. sahlbergii Stål, 1872 restricted to Brazil; and E. graziae sp. nov. from Brazil and Argentina. The E. ovina group can be identified by the apex of the second pair of wings narrowing distally and by a tumid area on the ventral surface of the pygophore (male genitalia) projected posteriorly. Descriptions, measurements, and illustrations of the metasternal process, external and internal genitalia of male and female are provided. A map with the distribution of the species is presented. The holotype of Edessa ovina is designated here. Edessa argali Breddin, 1903 is considered a junior synonym of E. impura. Females of E. ovina and E. impura, and male of E. sahlbergii are described for the first time.

The new species, Bulbophyllum manhdatii (B. sect. Brachyantha) discovered in Da Lat Plateau, Lam Dong Province (southern Vietnam) is described here. This new species is close to B. pumilio but clearly differs in densely crowded pseudobulbs and their shape, shorter inflorescence, lateral sepals forming a narrow acute tube slightly flattened at the base, lip without median keel, and longer stelidia. In addition, a new national record, B. seidenfadenii, from the same section is also reported from the first time from North Vietnam.

A new species, Stemonitis sichuanensis, collected in Gexigou National Natural Reserve, Sichuan province, China, is described herein. This new species has a columella that usually ends in an ovoid to triangular expansion at the apex of the sporotheca and small spores (about 6–7 μm in diam.). We present a scanning electron micrograph study of S. sichuanensis and a key to the species in the genus Stemonitis. Holotype specimens of S. sichuanensis are deposited in the Herbarium of the Mycological Institute of Jilin Agricultural University (HMJAU), Changchun, China. We also report a new record of another species of Stemonitis, S. marjana Y. Yamam., in this paper, specimens of which are also deposited in the HMJAU.

A new species of Placospongia is described from Bahia State, Brazil. Placospongia giseleae sp. nov.. The specimen is found on the underside of rocks in shallow waters (0-20m), and is unique by having a spiculation consisting of two tylostyle categories, selenasters and acanthomicrorhabds. In addition, Placospongia ruetzleri, is recorded for the first time to Bahia state, 2.974 km southwards from its type locality, the Guyana shelf. The diversity of Placospongia species is raised from two to four taxa. An identification key for Western Atlantic Placospongia species is presented.

The genus Minagenia Banks, 1934 is reported for the first time from Australia. A new species, M. lasallei Decker, Rodriguez & Pitts, sp. nov. (Australia: from Queensland to Tasmania), is described and illustrated. A key to the four species from the Australasian and Oriental regions is given. Three species are removed from Asian Minagenia: granulosa Tsuneki, 1989, comb. nov., to the genus Priocnemis Schiødte, 1837; pempuchiensis Tsuneki, 1989, comb. nov., to the genus Nipponodipogon Ishikawa, 1965; and assimilis Smith, 1861, comb. nov., to the genus Dichragenia Haupt, 1950. Minagenia alticola Tsuneki, 1989 is a member of an undescribed genus. Placement of this species is maintained in Minagenia until the new genus can be described in a future work. Minagenia brevicornis (Banks, 1934) is redescribed.

ABSTRACT The accumulation of salts in the soil profile produces conditions that affect the growth of crops. The effects of these conditions on crops and the intensity of these effects depend on the quantity and type of salts that predominate and are also influenced by soil characteristics and climate, among other aspects. The salinization of agricultural soils is a serious problem facing agriculture today. The use of organic amendments has increased in recent years, acting on the texture of the soil, correcting compaction or granularity problems, and influencing chemical and/or biological reactions. The objectives of this work were to analyze the use of compost and vermicompost using different analysis techniques to determine the influence of conditions on the remediation of a saline soil. In saturation extracts of soil, compost, and vermicompost, a Zeta potential value 2.34-2.44 times more negative (more-stable colloids) than that in the soil colloids was observed in the amendments. The values of electrophoretic mobility were more negative in the organic amendments compared with the soil. This is the first time that these parameters have been reported for these purposes and for a saline soil. In this study, the soil has low organic matter content (1.65%), so these amendments are expected to improve soil quality and texture, achieving the recovery of saline soils.
