Antarctic Marine Fungi
Despite the harsh conditions, fungi are ubiquitously present in Antarctic ecosystems. The key to fungal success can be due to the vast array of specialized molecules, which allowed their colonization in almost every habitat of our Planet. In Antarctic marine environments, the fungal specific adaptions to low temperatures lead to the production of structurally novel enzymes and secondary metabolites that provide competitive advantages over other microorganisms. The bioprospecting of Antarctic fungi for new bioactive compounds and enzymes is important not only for elucidating their ecological role but also useful for developing blue biotechnologies.

Black Fungi Research: Out-of-This-World Implications
Black fungi are an ecological group of melanized fungi specialized in extremotolerance and assumed to be among the most stress-resistant eukaryotes on Earth. Multi-omics studies have provided significant evidence that they have a peculiar response to stress that differs considerably from that of common mesophilic hyphomycetes. Survival strategies displayed by these organisms have situated them as attractive models for astrobiology and, in general, for studies directed towards the definition of the actual limits for life. Moreover, the ascertained aptitude of black fungi for degradation of hazardous volatile pollutants and for plastic breakdown suggests prospective application of several species.

Challenges in Ramularia collo-cygni Control
Ramularia leaf spot (RLS), caused by the fungus Ramularia collo-cygni, has recently become widespread in Europe. Succinate dehydrogenase inhibitor (SDHI) and demethylation inhibitor (DMI) fungicides are mainly applied for disease control on barley fields, but pathogen isolates with a reduced sensitivity can cause difficulties. There is an urgent need for new spring barley cultivars that are more resistant to RLS development and can inhibit R. collo-cygni epidemics.

Mucormycosis—Emerging Fungal Threats
Mucormycosis is an opportunistic fungal infection due to organisms of the Zygomycetes class and the order of Mucorales that can cause various types of infections. In recent years, an increasing phenomenon has been observed—invasive fungal infections especially in the healthcare setting. Among immucompromised patients, an important clinical emergency could be represented by mucormycosis. The epidemiology of mucormycosis has shown an alarming trend and its incidence is rising globally. Four elements are fundamental for a successful treatment: rapid diagnosis, reduction of predisposing factors (if possible), surgical debridement of infected tissues, and appropriate antifungal therapy.

Chytrids in Soil Environments: Unique Adaptations and Distributions
Chytridiomycota (zoosporic true fungi) have a consistent presence in soils and have been frequently identified within many diverse terrestrial environments. However, Chytridiomycota and other early-diverging fungi have low representation in whole-genome sequencing databases compared to Dikarya. New molecular techniques have provided insights into the diversity and abundance of chytrids in soils and the changes in their populations both spatially and temporally. Chytrids complete their life cycle within rapidly changing soil environments where they may be more common within micropores due to protection from predation, desiccation, and extreme temperatures. Reproductive and morphological changes occur in response to environmental changes including pH, fluctuating nutrient concentrations, and metals at levels above toxic thresholds. Rhizoids share some features of hyphae, including the spatial regulation of branching and the ability to attach, adapt to, and proliferate in different substrates, albeit on a microscale. Soil chytrids provide a pool of novel enzymes and proteins which enable a range of lifestyles as saprotrophs or parasites, but also can be utilised as alternative tools with some biotechnological applications. Thus, 3D live-cell imaging and micromodels such as MicroCT may provide insight into zoospore functions and rhizoid plasticity, respectively, in response to various conditions. A combination of classical techniques of soil chytrid baiting with simultaneous molecular and ecological data will provide insights into temporal population changes in response to environmental change. The authors emphasise the need to review and improve DNA-based methodologies for identifying and quantifying chytrids within the soil microbiome to expand our knowledge of their taxonomy, abundance, diversity, and functionality within soil environments.

Techniques for Antifungal Combinations
The general approach of studying antifungal combinations is (i) to choose an experimental technique, (ii) to obtain raw numerical data, (iii) to analyze these data either graphically or numerically; (iv) to interpret the results, and (v) to conclude on the mode of interaction: synergy, indifference (no interaction), or antagonism.

Fungal Enzymes Involved in Plastics Biodegradation
Plastic pollution is a growing environmental problem, in part due to the extremely stable and durable nature of this polymer. As recycling does not provide a complete solution, research has been focusing on alternative ways of degrading plastic. Fungi provide a wide array of enzymes specialized in the degradation of recalcitrant substances and are very promising candidates in the field of plastic degradation.

Coccidioidomycosis
Coccidioidomycosis, also known as Valley fever, is an endemic fungal infection commonly found in the southwestern parts of the United States. However, the disease has seen an increase in both in its area of residency and its prevalence. This entry compiles some of the latest information on the epidemiology, current and in-development pharmaceutical approaches to treat the disease, trends and projections, diagnostic concerns, and the overlapping dynamics of coccidioidomycosis and COVID-19, including in special populations. This entry provides an overview of the current diagnostic and therapeutic strategies and identifies areas of future development.

Molecular Markers
Fungi are amongst the most abundant and diverse organisms. Despite being widely known for their adverse role in food spoilage or as pathogens for humans, animals, or plants, they also present several beneficial effects. Fungi contribute to human well-being due to their role as decomposers, degrading decay matter into smaller molecules which can be easily used by other ecosystem members. These organisms can produce medicinal compounds or modulate protective immune responses in human intestine. Fungi intervene in diverse food processes or act as a food supply. Due to fungal diversity, the unequivocal identification of these organisms is crucial to increasing their practical applications and decreasing their adverse effects.

The Genus Candida auris
C. auris has unprecedently emerged as a multi-drug resistant fungal pathogen considered a serious global threat due to its potential to cause nosocomial outbreaks and deep-seated infections with staggering transmissibility and mortality, that has put in check the health authorities and institutions worldwide for more than a decade now. Due to its unique features not observed in other yeasts, it has been categorized as an urgent threat by the Centers for Disease Control and Prevention and the rest of international agencies. Moreover, epidemiological alerts have been released in view of the increase of healthcare-associated C. auris outbreaks in the context of the COVID-19 pandemic. This review summarizes the current evidence on C. auris since its first description, from virulence to treatment and outbreak control, and highlights the knowledge gaps and future directions for research efforts.
