An undetermined saprobic fungal taxon from Yunnan (China) is revealed as a new genus in Scortechiniaceae (Coronophorales). The novel taxon, Yuxiensis, is characterized by immersed to erumpent, semi-globose ascomata, which are not surrounded by any tomentum or conspicuous subiculum, a subcylindrical quellkörper in the centrum, clavate asci with long pedicels and allantoid hyaline ascospores with granular contents. Maximum likelihood and Bayesian posterior probability analyses based on LSU, ITS, tef1 and rpb2 sequence data depict a close phylogenetic relationship of the new genus to Pseudocatenomycopsis, hence, confirming its placement in Scortechiniaceae. Parasympodiellaceae, thus far belonging to Parasympodiellales, is transferred to Coronophorales based on multi-gene phylogenetic evidence. Additionally, the incertae sedis monotypic genus Arthrocristula is treated as a synonym of Parasympodiella, with Arthrocristula hyphenata recombined as Parasympodiella hyphenata comb. nov., as the type strain of Arthrocristula hyphenata clusters inside the Parasympodiellaceae clade along with other Parasympodiella taxa.

A new genus Guayaquilia is established to accommodate Idriella cubensis based on morphology and phylogenetic analysis. DNA sequence data place these specimens as incertae sedis separate from Microdochiaceae (Xylariales), forming a monophyletic lineage separated from Neoidriella desertorum and phylogenetically distant from Idriella. The novel genus is characterized by macronematous, tree-like, fasciculate, profuse dichotomously, alternately, or irregularly branched, brown conidiophores with polyblastic, denticulate, sympodial extended, intercalary and terminal conidiogenous cells that produce solitary, sublunate, subnavicular, lunate, inequilateral, (0–)1-septate, hyaline conidia.

AbstractThe relationship ofAspicilia uxoriswithinMegasporaceaeis assessed within a phylogenetic context. ‘Aspicilia’uxorisand other related species are recovered as sister to the genusLobothallias. str. and described here as a new genus.Teuvoa(Ascomycota,Megasporaceae) is erected based on nuclear ITS and LSU sequence data and morphological characters. In addition toTeuvoa uxoris, a second species,T. junipericola,is added to the new genus based on material collected from North America.Teuvoa junipericola, T. uxorisandT. tibeticaform a group with 8-spored asci, absence of extrolites, rather short-sized conidia and ascospores, lack of a subhypothecial algal layer, and different substratum preferences (on organic substratum) with a sister relationship to genusLobothallias. lat. (AspiciliasubgenusPachyothalliaClauzade & C. Roux). Based on spore measurements of the holotypes,Lecanora ferganensisTomin from central Asia (Kyrgyzstan, Tajikistan and Uzbekistan),Lecanora atrodiscataGintovt, from Tajikistan andLecanora takyroidesDzhur. from Turkmenistan are new synonyms toT. uxoris. A lectotype forLecanora ferganensisis designated, expanding the known distribution ofT. uxorisfrom Algeria, Morocco and Spain, into Central Asia.

The phylogenetic position of Xenoturbella spp. has been uncertain since their discovery in 1949. It has been recently suggested that they could be related to Ambulacraria within Deuterostomia. Ambulacraria is a taxon that has been suggested to consist of Hemichordata and Echinodermata. The hypothesis that X. bocki was related to Ambulacraria as well as the hypothesis of a monophyletic Ambulacraria is primarily based on the analysis of DNA sequence data. We tested both phylogenetic hypotheses using antibodies raised against SALMFamide 1 and 2 (S1, S2), neuropeptides isolated from echinoderms, on X. bocki and the enteropneust Harrimania kupfferi. Both species showed distinct positive immunoreactivity against S1 and S2. This finding supports the Ambulacraria-hypothesis and suggests a close phylogenetic relationship of X. bocki to Ambulacraria. In particular, the presence of immunoreactivity against S2 can be interpreted as a synapomorphy of Enteropneusta, Echinodermata, and Xenoturbella spp.

An interesting hyphomycetous taxon was collected on submerged wood in a freshwater stream in Trat Province, Thailand. It is morphologically similar to endophragmiella-like taxa, characterized by macronematous, mononematous conidiophores, monoblastic, enteroblastic conidiogenous cells and clavate to obovoid, septate brown conidia. The unique feature of this taxon is that the mature conidium often bears a young new conidial primordium which develops percurrently from a lower semi-transparent cell and they secede simultaneously. Phylogenetic analyses of a combined LSU, SSU and RPB2 sequence data support the placement of this fungus together with Platytrachelon and close to the family Papulosaceae within Diaporthomycetidae, Sordariomycetes. A new genus is introduced to accommodate the new taxon as Aquimonospora. The novel species Aquimonospora tratensis is described and illustrated and is compared with other morphologically similar taxa.

A new ascomycete species, inhabiting decaying bamboo culms, is introduced in this paper based on morphology and molecular evidence. Analyses of partial LSU sequence data place the taxon in a monophyletic clade within the order Pleosporales. Morphological characters of the taxon are also distinct from other members of Pleosporales. Ligninsphaeria jonesii gen. et sp. nov. is therefore introduced to accommodate the new taxon, which is characterized by its clypeate, scattered, deeply immersed ascomata, with a slit-like opening, long ostioles, cellular pseudoparaphyses, clavate asci containing broad-fusiform and 1-septate ascospores surrounded by a gelatinous cap at both ends. The phylogenetic analyses show that the new taxon is phylogenetically close but distinct from the families Amniculicolaceae and Testudinaceae, and forms a distinct clade from other taxa in Pleosporales. The new taxon is described and compared with similar taxa. A new genus Ligninsphaeria (Pleosporales, incertae sedis) is introduced to accommodate this distinct lineage.

The previously unknown larva of the genus Nandeva Wiedenbrug, Reiss and Fittkau (Chironomidae: Chironominae) is suggested to be a candidate from tropical northern Australia belonging to the tribe Tanytarsini. The basis for the assumption is DNA analysis showing maximum values of Bayesian posterior probability and Bootstrap support for an exclusive sister relationship of the unreared larva with a male of Nandeva from South America. The monophyly of Nandeva has high support as a member of the subtribe Tanytarsina, although its precise relationships within this subtribe lack support.  Larval morphology is described and illustrated, and conforms to the subtribe Tanytarsina in tribe Tanytarsini. The historical tempo is discussed in relation to fossils and dating of pertinent nodes and the term ‘pseudo-gondwanan’ is used to described an extant restricted austral range, but with fossils showing a wider past distribution in the north.

The new micro-dolichopodid genus Hurleyella and two new species, H. cumberlandensis and H. brooksi are described from the Nearctic. Hurleyella resembles the subfamily Medeterinae in having the legs bare of major setae, a depressed posterior mesonotum, and concave dorsal postcranium, but the complex male genitalia is unlike the relatively simple structure of traditional Medeterinae (e.g., Medetera, Thrypyicus, Corindia, etc.). Until the relationship of Hurleyella to other genera can be determined, and the limits of dolichopodid subfamilies refined, it should be considered as incertae sedis.

The 5S rRNAs from Halobacterium vallismortis, Halobacterium marismortui (the Ginzburg strain), and two extremely halophilic isolates that exhibit an unusual "box-shaped" morphology were examined by ribonuclease T1 fingerprinting. The 5S rRNAs are found to be essentially identical and it is concluded that the four strains are in fact close phylogenetic relatives that should properly be assigned to a single genus. Comparison with previously available 5S rRNA sequence data from Halobacterium cutirubrum and Halococcus morrhuae indicates that the four strains examined here are quite distinct from both. It is further argued that this molecular evidence is not inconsistent with the previously proposed creation of a new genus, Haloarcula.

This booklet is a collection of the position statements accepted for the HRI’20 conference workshop “Social Cognition for HRI: Exploring the relationship between mindreading and social attunement in human-robot interaction” (Wykowska, Perez-Osorio & Kopp, 2020). Unfortunately, due to the rapid unfolding of the novel coronavirus at the beginning of the present year, the conference and consequently our workshop, were canceled. On the light of these events, we decided to put together the positions statements accepted for the workshop. The contributions collected in these pages highlight the role of attribution of mental states to artificial agents in human-robot interaction, and precisely the quality and presence of social attunement mechanisms that are known to make human interaction smooth, efficient, and robust. These papers also accentuate the importance of the multidisciplinary approach to advance the understanding of the factors and the consequences of social interactions with artificial agents.

This chapter approaches police records as a genre that gains from being considered in its relationships with other genres of writing. In particular, we will follow its long-standing relationship to detective fiction, the novel, and biography. Going further, the chapter emphasizes the intermedia character of police records not just in our time but also throughout their existence, indeed from their very origins. This approach opens to a more inclusive media history of police files. We will start with an analysis of the seminal late nineteenth-century French manuals prescribing the writing of a police file, the famous Bertillon-method manuals. We will then track their influence following their adoption nationally and internationally, with particular attention to the politics of their adoption in the colonies. We will also touch briefly on the relationship of early policing to other disciplines, such as anthropology and statistics, before moving to a closer look at its intersections with photography and literature.
