Vanhorniaeucnemidarum Crawford is the only species of Vanhorniidae that occurs in North America. This species is rarely collected and thus the distribution is not well documented. Intending to uncover a more accurate range of this species, we assembled collection records from museums, personal collections and citizen science projects. Many of these records were non-digitised and had to be personally requested. Here we expand the known distribution of V.eucnemidarum to include nine new provinces and states: Manitoba, Connecticut, Oregon, Mississippi, Missouri, New Hampshire, New Jersey, Texas and Wisconsin. Although Quebec has been listed as a previous locality, the recorded province was mislabelled, so Quebec is now also officially a provincial record.

Abstract A description is provided for Sporisorium everhartii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: No fruits develop in infected parts of the plants. HOSTS: Andropogon glomeratus, A. brachystachys, A. floridanus, A. furcatus, A. geradi, A. glomeratus, A. microstachyus, A. scoparius, A. ternarius, A. virginicus, Gayona densiflora, Hyparrhenia diplandra, H. ruprechtii, Schizachyrium hirtiflorum (A. hirtiflorus), S. tenerum (A. tener) and S. scorparium (Poaceae). GEOGRAPHICAL DISTRIBUTION: AFRICA: Congo, South Africa (Transvaal). NORTH AMERICA: Mexico, USA (Alabama, Connecticut, Florida, Georgia, Louisiana, Maine, Mississippi, Montana, Nebraska, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Tennessee, Vermont, Virginia). CENTRAL AMERICA: Cuba. TRANSMISSION: Probably by air-borne teliospores. Wind is the most common dispersal mode of smut teliospores.

Abstract A description is provided for Protoventuria alpina, which produces spots on living leaves but is more often encountered as ascomata on dead leaves which may have died as a result of parasitism by the fungus. It occurs in at least some of the habitats where its associated plants are found, including moorland and open conifer woodland. Some information on its associated organisms and substrata, habitats, dispersal and transmission and conservation status is given, along with details of its geographical distribution (North America (Canada (Newfoundland, Quebec), USA (California, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Virginia, Washington)), Europe (Austria, Finland, Iceland, Italy, Norway, Slovakia, Sweden, Switzerland, UK)) and hosts (including Arctostaphylos spp.). No reports of negative economic impacts of this fungus have been found.

The use of crowdsourced data is growing rapidly, particularly in ornithology. Citizen science greatly contributes to our knowledge, however, little is known about the reliability of data collected in that way. We found, using an online picture quiz, that self-proclaimed expert birders were more likely to misidentify common British bird species as exotic or rare species, compared to people who rated their own expertise more modestly. This finding suggests that records of rare species should always be considered with caution even if the reporters consider themselves to be experts. In general, however, we show that self-rated expertise in bird identification skills is a reliable predictor of correct species identification. Implementing the collection of data on self-rated expertise is easy and low-cost. We therefore suggest it as a useful tool to statistically account for variability in bird identification skills of citizen science participants and to improve the accuracy of identification data collected by citizen science projects.

In this paper, we focus on different roles in citizen science projects, and their respective relationships. We propose a tripartite model that recognises not only citizens and scientists, but also an important third role, which we call the ‘enabler’. In doing so, we acknowledge that additional expertise and skillsets are often present in citizen science projects, but are frequently overlooked in associated literature. We interrogate this model by applying it to three case studies and explore how the success and sustainability of a citizen science project requires all roles to be acknowledged and interacting appropriately. In this era of ‘wicked problems’, the nature of science and science communication has become more complex. In order to address critical emerging issues, a greater number of stakeholders are engaging in multi-party partnerships and research is becoming increasingly interdisciplinary. Within this context, explicitly acknowledging the role and motivations of everyone involved can provide a framework for enhanced project transparency, delivery, evaluation and impact. By adapting our understanding of citizen science to better recognise the complexity of the organisational systems within which they operate, we propose an opportunity to strengthen the collaborative delivery of both valuable scientific research and public engagement.

Over the last decade, a variety of ‘citizen science’ projects have turned to video games and other tools of gamification to enrol participants and to encourage public engagement with scientific research questions. This article examines the significance of sf in the field of citizen science, focusing on projects such as Eyewire, Be a Martian!, Sea Hero Quest, Play to Cure: Genes in Space, Forgotten Island and the ‘Project Discovery’ experiments in EVE Online. The sf stories that frame these projects often allegorise the neoliberal assumptions and immaterial labour practices of citizen science, even while seeming to hide or disguise them. At the same time, the fictional frames enable players to imagine social and technical innovations that, while not necessarily achievable in the present, nevertheless point to a future of democratic science, social progress and responsible innovation - blips of utopian thought from the zones of crowdsourced labour.

Abstract A description is provided for Barrmaelia oxyacanthae, saprobic on wood of various trees. Some information on its dispersal and transmission and conservation status is given, along with details of its geographical distribution (Africa (South Africa), North America (Canada, USA (New Jersey, North Dakota, South Dakota, Vermont, Virginia)), Asia (Georgia, Japan, Kazakhstan (Aktyubinskaya oblast), Pakistan), Europe (Belarus, Belgium, former Czechoslovakia, Finland, France, Germany, Italy, Lithuania, Luxembourg, Netherlands, Norway, Poland, Sweden, Switzerland, Ukraine, UK, former Yugoslavia)). B. oxyacanthae is sometimes found on elm twigs previously gnawed by rabbits.

Abstract A description is provided for Isthmiella faullii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Apparently confined to Abies balsamea. DISEASE: Causes a needle blight of Abies balsamea. According to Darker (1932), it 'is the commonest and most destructive of the Hypodermataceae on Abies balsamea in eastern North America'. It is particularly damaging to seedlings and juvenile plants. In northern Ontario, from where the disease was originally identified, infection occurs during the summer, but signs of the disease do not appear until the following spring, when needles become brown and conidiomata develop, conidia being discharged in July, and shortly after this ascomata begin to form, maturing in July of the following year. GEOGRAPHICAL DISTRIBUTION: Reported from Canada: Nova Scotia, Ontario, Quebec and USA: Michigan and New Hampshire. TRANSMISSION: Through air dispersal of ascospores, which directly infect the leaves (Darker, 1932).
