This work presents the genetic and morphological diversity of small <em>Cortinarius</em> subgenus <em>Telamonia</em> species found from moist <em>Salix</em> thickets in Finland. The boreal fungi were compared with several type and other specimens from the alpine zone or similar habitats from the temperate zone. The boreal and alpine zones had many common species: nearly all boreal species grew in the alpine zone with dwarf <em>Salix</em>. The species often had wide distributions, extending to North America. The genetic analyses consisted of ITS and RPB2 sequences. Both genetic and morphological variation was high. The species formed complexes, where the boundaries among species were often obscure. Very close sibling species were delimited based on differences at the same sites. Twenty-three boreal species were recognized. Four of them are described here as new: <em>C. paulus</em> and <em>C. paululus</em> as sibling species to <em>C. pauperculus</em> J.Favre, <em>C. rusticelloides</em> as a sibling species to <em>C. rusticellus</em> J.Favre, and <em>C. vienoi</em> as a sibling species to <em>C. perzonatus</em> Reumaux. <em>Cortinarius sagarum</em>, a sibling species to <em>C. comatus</em> J.Favre and <em>C. vulpicolor</em> M.M.Moser & McKnight, is described as new from arctic-alpine zones.

140 bryophyte taxa (10 liverworts and 130 mosses) were recorded during a field trip led to a bryologically completely unexplored territory of Serbia in the vicinity of Čačak town, namely the Ovčar, Kablar, and Vujan Mts. 13 species are of conservation interest; rare, threatened in the Balkans or even in Europe. The bryophyte fl ora of the studied mountains can be characterised by high number of common species of the temperate zone of Europe. Almost half of the species found belong to this category. Another 20% of the species found are subboreal, boreal species, while more than 20% of the species collected have Mediterranean, sub-Mediterranean character.

Twenty-four fossil gall midges (Cecidomyiidae) described from 1917–2020 from Mesozoic deposits, mostly ambers, are reviewed. Information from the original publications is used as the basis for reinterpretation, when such is regarded as appropriate here. As a result, the fossil record of cecidomyiids from the Mesozoic comprises representatives of the following subfamilies and tribes, all mycophagous (numbers in parentheses refer to species described): Catotrichinae (1); Micromyinae: Catochini (2), Amediini (1), Campylomyzini (1), Micromyini (2) and Aprionini (1); Winnertziinae: Heteropezini (2), Diallactiini (4) and Winnertziini (1); Porricondylinae: Dicerurini (1). Other Winnertziinae (3) and Micromyinae (5) cannot be classified to tribe because information on critical morphological structures is unavailable; they are thus considered incertae sedis. Members of the Lestremiinae sensu stricto are unrecorded from the Mesozoic, as are any Cecidomyiinae (the only subfamily containing phytophages and predators). Commonly occurring reasons for misinterpretation of amber fossils are the non-recognition of artefacts and the unfamiliarity with group-specific literature regarding prevailing taxonomic concepts and the morphological diversity found in Cecidomyiidae. These causes as well as obvious differences between neontological and paleontological taxonomic practices are discussed. Amediini trib. nov. Jaschhof, 2021 is introduced as a new tribe of the Micromyinae, to absorb the genera Amedia Jaschhof, 1997 (extant, North America, type genus), Amediella Jaschhof, 2003 (extant, New Zealand) and Eltxo Arillo & Nel, 2000 (extinct, Alava amber). A diagnosis of the new tribe is given. Krassiloviolini Fedotova & Perkovsky, 2017 is a new junior synonym of Heteropezini Schiner, 1868. Amediini Plakidas, 2017 and Zarqacecidomyius singularis Kaddumi, 2007 are nomina nuda.

AbstractTrichadenotecnum alexanderae Sommerman is shown to represent one biparental (= euphrasic) species capable of facultative parthenogenesis (thelytoky) and three uniparental (= obligatorily parthenogenetic) sibling species, as determined by tests for mating, life history observations, and morphological analysis of specimens over the geographic range of the species complex. The name T. alexanderae is restricted to the biparental species because the holotype is a male. The three uniparental species are here named and described as T. castum n. sp., T. merum n. sp., and T. innuptum n. sp. The female of T. alexanderae is redescribed to allow its separation from the three uniparental species. A key to females of the species complex is supplied. All three uniparental species were derived from the biparental ancestor of T. alexanderae. Most collections of populations represented only by females consist of one or more uniparental species. Facultative parthenogenesis is shown to maintain a population of T. alexanderae through one generation only. The biparental species is found not to be restricted geographically to a relictual or peripheral range within the species complex, but to occupy a rather wide, north-temperate distribution across eastern North America.

Genus Camptocercus is represented in North America by four species. Camptocercus rotundus Herrick, 1882 is proved to be a valid species and is redescribed here. C. rotundus differs from its sibling species, neotropical C. dadayi Stingelin, 1913, in morphology of the postabdominal claw, presence of posteroventral denticles on valves, and morphology of the male postabdomen. C. rotundus is distributed in South Canada and North USA from Pacific to Atlantic coast, whereas C. dadayi is found in Mexico and South-East USA. C. oklahomensis Mackin, 1930 is found in Central USA. C. streletskaye Smirnov, 1998, previously known from Chukotka and Magadan Area of Russia, was found in Alaska for the first time.

Abstract A description is provided for Toruiopsis candida. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Torulopsis candida is one of the less common species of the commensal yeast flora in humans and has been associated with both superficial and systemic infections. The organism has occasionally been implicated in cases of fungal septicaemia and has been isolated from urine, vagina and feet. Veterinary associations of T. candida include bovine mastitis, bovine and ovine abortion and isolation from cervical swats in mares. Pathogenicity studies have been carried out by Khon et al. who found Torulopsis glabrata to be non-pathogenic to normal mice following intravenous inoculation with up to 10 cells but 50% mortality in cortisone treated mice inoculated with similar doses (Sabouraudia 18: 319-327, 1980). The diseased mice were found to have macroscopic lesions on liver, lung, kidney and spleen. GEOGRAPHICAL DISTRIBUTION: Africa (Sudan); Asia (Japan, Kuwait); Europe (Austria, Belgium, Czechoslovakia, Finland, France, Greece, Italy, UK); North America (USA); South America (Brazil, Venezuela).

Thirteen described species of outlet-breeding simuliids and five isomorphic sibling species of the Simulium venustum/verecundum complexes were collected in 1978 and 1979. Prosimulium fuscum, P. mixtum, Simulium aestivum, S. aureum, S. decorum; S. tuberosum, S. venustum (CC) and S. vernum were the most widely distributed species while S. aureum, S. decorum and S. venustum (CC) were the most abundant. Simulium decorum, S. tuberosum and S. venustum (AC(gB) and CC) were present at the same sites during both years while the remaining species varied in their occurrence at a specific site between the two years. Succession of Simulium spp. in late winter and spring was similar to that reported from other areas of northern North America. Most Simulium spp. studied were multivoltine while S. corbis, S. croxtoni and S. venustum (A/C) were univoltine. Simulium decorum had single or multiple generations, depending on the site. Larvae of S. venustum (A/C) and most species of the subgenus Eusimulium attached to trailing vegetation, while S. corbis, S. decorum, and S. tuberosum attached more frequently to submerged rocks and sticks. Prosimulium fontanum, S. gouldingi, S. venustum (CC and AC(gB)), and S. verecundum (A/C and ACD) did not demonstrate preference for a particular substrate. Reduction in stream flow affected the number of cohorts of S. aestivum and S. aureum and the number of generations per year of S. aureum and S. vernum.

AbstractDeinotheriidae Bonaparte, 1845 is a family of browsing proboscideans that were widespread in the Old World during the Neogene. From Miocene deposits in the Indian subcontinent, deinotheres are known largely from dental remains. Both large and small species have been described from the region. Previously, only small deinothere species have been identified from Kutch in western India. In the fossiliferous Tapar beds in Kutch, dental remains have been referred to the small species Deinotherium sindiense Lydekker, 1880, but the specimens are too fragmentary to be systematically diagnostic. Here, we describe a large p4 of a deinothere from the Tapar beds and demonstrate that it is morphologically most similar to Deinotherium indicum Falconer, 1845, a large species of deinothere, thereby confirming the identity of deinotheres at Tapar. Deinotherium indicum from Tapar is larger than other deinotheres identified from Kutch and is the first occurrence of the species in the region. This new specimen helps constrain the age of the Tapar beds to the Tortonian and increases the biogeographic range of this species—hitherto only known from two localities on the subcontinent. This specimen also highlights the morphological diversity of South Asian deinothere p4s and allows us to reassess dental apomorphies used to delimit Indian deinothere species. Lastly, we argue that by the late Miocene, small deinotheres in Kutch were replaced by the large Deinotherium indicum.
