Maize-Fusarium associations and their mycotoxins: Insights from South Africa.

For maize, a staple food in South Africa, there is a lack of comprehensive knowledge on the mycotoxin-producing fungal diversity. In this study, a fungal community profile was established using culture-dependent methods for 56 maize seed samples that were also analysed for 13 mycotoxins. The fungal isolates were identified by morphology and DNA sequencing.

Sporothrix and Sporotrichosis: A South African Perspective on a Growing Global Health Threat.

Sporotrichosis is a disease that arises from a fungal infection caused by members of the Ascomycete genus Sporothrix. The disease has a unique history in South Africa, due to an association with gold mines, where large numbers of mine workers were infected in the 1930s and 1940s. This was likely driven by hot humid conditions and timber supports used in these mine shafts.

A new from wooden utility poles in South Africa.

During a survey of fungi on electricity utility poles in South Africa, a diverse range of fungi were discovered. was frequently isolated, with five species identified using ITS and β-tubulin () sequences. These were , , , and a potential new species.

New and Interesting Fungi. 7.

Two new genera, 17 new species, two epitypes, and six interesting new host and / or geographical records are introduced in this study. New genera include: (based on ) and (based on ). New species include: (from hypersaline sea water, Qatar), (from mycangia of , USA), (on leaves of , Brazil), (from pre-stored , South Africa), (from soil, South Africa), (from dead capsule of , Germany), (from house dust, Canada), (from soil, South Africa), (on ascomata of ascomycete on twigs of , South Africa), (on leaf litter, Spain), (on larva, Thailand), (from soil, South Africa), (from pasture mulch, South Africa), (from soil, South Africa), (on stem, bark of living tree of sp.

Cultures as types and the utility of viable specimens for fungal nomenclature.

The debates over the requirement of the International Code of Nomenclature for algae, fungi, and plants (ICNafp) for a viable specimen to represent the name-bearing type material for a species or infraspecific taxon have a long history. Taxonomy of fungi commonly studied as living cultures exemplified by yeasts and moulds, strongly depend on viable reference material. The availability of viable cultures is also particularly useful for several groups of filamentous and dimorphic fungi.

IMA Genome - F19 : A genome assembly and annotation guide to empower mycologists, including annotated draft genome sequences of Ceratocystis pirilliformis, Diaporthe australafricana, Fusarium ophioides, Paecilomyces lecythidis, and Sporothrix stenoceras.

The pace at which Next Generation Sequence data is being produced continues to accelerate as technology improves. As a result, such data are increasingly becoming accessible to biologists outside of the field of bioinformatics. In contrast, access to training in the methods of genome assembly and annotation are not growing at a similar rate.

Novel species of fungi described in this study include those from various countries as follows: , on whitefly, on bark of , from soil under , on leaf spot of , and on leaf spot of . , on fully submersed siliceous schist in high-mountain streams, and on the lower part and apothecial discs of on a twig. , on decaying wood, from moist soil with leaf litter, on a trunk of a living unknown hardwood tree species, and on dead twigs of unidentified plant.

Fungal Species and Mycotoxins Associated with Maize Ear Rots Collected from the Eastern Cape in South Africa.

Maize production in South Africa is concentrated in its central provinces. The Eastern Cape contributes less than 1% of total production, but is steadily increasing its production and has been identified as a priority region for future growth. In this study, we surveyed ear rots at maize farms in the Eastern Cape, and mycotoxins were determined to be present in collected samples.

Blastobotrys nigripullensis, a new yeast species isolated from a fungal outbreak on an ancient Roman shipwreck in the Netherlands.

A new species of the yeast genus Blastobotrys was discovered on ancient ship timbers in the Netherlands. The species had developed on the wood of a river barge dating to the Roman period. The growth occurred after the preservative polyethylene glycol (PEG 4000) was washed out of some of the timbers due to an undetected leak in the storage unit.

New Resinogalea species from Araucaria araucana resin in Chile and reclassification of the genus in the Cryptocaliciomycetidae.

Araucaria araucana is an ancient conifer, native to the mountain ranges in Chile and Argentina. These trees host a large number of organisms, mainly insects, strongly or even exclusively associated with them. The recent emergence of a novel canker disease on A.

A monograph of section .

section encompasses white- or yellow-sporulating species mostly isolated from indoor and cave environments, food, feed, clinical material, soil and dung. Their identification is non-trivial due to largely uniform morphology. This study aims to re-evaluate the species boundaries in the section and present an overview of all existing species along with information on their ecology.

diversity from the Gcwihaba Cave in Botswana and description of one new species.

A fungal survey of the Gcwihaba Cave from Botswana found to be one of the more common fungal genera isolated. The 81 strains were identified using sequences and comparing these to a curated reference dataset. Nineteen species were identified representing eight sections (sections and ).

This species is phenotypically and phylogenetically closely related to and . The phylogenetic and morphological analyses of 37 strains previously identified as , and revealed that this clade incudes eight species: the accepted species , and , the newly proposed species , and , and the new combinations (basionym ) and (basionym ).

: more than a node or a foot-shaped basal cell.

Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family . Thus, an alternate hypothesis, namely a very broad concept of the genus was proposed. In doing so, however, a significant body of data that supports distinct genera in based on morphology, biology, and phylogeny is disregarded.
