Chytridiomycetes is a class of fungi. Members are found in soil, fresh water, and saline estuaries. They are first known from the Rhynie chert. It has recently been redefined to exclude the taxa Neocallimastigomycota and Monoblepharidomycetes, which are now a phylum and a sister-class respectively.
The Clavulinaceae are a family of fungi in the order Cantharellales. The family is not well defined, but currently comprises species of clavarioid fungi as well as some corticioid fungi. These species are nutritionally diverse, some being ectomycorrhizal, others wood-rotting saprotrophs, others lichenized, and yet others lichenicolous.
Eucalyptus gomphocephala, known as tuart, is a species of tree, one of the six forest giants of Southwest Australia. Tuart forest was common on the Swan coastal plain, until the valuable trees were felled for export and displaced by the urban development around Perth, Western Australia. The wood is dense, hard, water resistant and resists splintering, and found many uses when it was available. Remnants of tuart forest occur in state reserves and parks, the tree has occasionally been introduced to other regions of Australia and overseas. Remaining trees are vulnerable to phytophthora dieback, an often fatal disorder, including a previously unknown species discovered during analysis of dead specimens.
Armillaria luteobubalina, commonly known as the Australian honey fungus, is a species of mushroom in the family Physalacriaceae. Widely distributed in southern Australia, the fungus is responsible for a disease known as Armillaria root rot, a primary cause of Eucalyptus tree death and forest dieback. It is the most pathogenic and widespread of the six Armillaria species found in Australia. The fungus has also been collected in Argentina and Chile. Fruit bodies have cream- to tan-coloured caps that grow up to 10 cm (4 in) in diameter and stems that measure up to 20 cm (8 in) long by 1.5 cm (1 in) thick. The fruit bodies, which appear at the base of infected trees and other woody plants in autumn (March–April), are edible, but require cooking to remove the bitter taste. The fungus is dispersed through spores produced on gills on the underside of the caps, and also by growing vegetatively through the root systems of host trees. The ability of the fungus to spread vegetatively is facilitated by an aerating system that allows it to efficiently diffuse oxygen through rhizomorphs—rootlike structures made of dense masses of hyphae.
The Pleosporales is the largest order in the fungal class Dothideomycetes. By a 2008 estimate it contains 23 families, 332 genera and more than 4700 species. The majority of species are saprobes on decaying plant material in fresh water, marine, or terrestrial environments, but several species are also associated with living plants as parasites, epiphytes or endophytes. The best studied species cause plant diseases on important agricultural crops e.g. Cochliobolus heterostrophus, causing southern corn leaf blight on maize, Phaeosphaeria nodorum causing glume blotch on wheat and Leptosphaeria maculans causing a stem canker on cabbage crops (Brassica). Some species of Pleosporales occur on animal dung and a small number occur as lichens and rock-inhabiting fungi.
Ruhlandiella is a genus of fungi within the family Pezizaceae. Ruhlandiella species are exothecial hypogeous fungi, which are essentially truffles that lack the outer layer or peridium. Ruhlandiella species are widely distributed in Nothofagaceae forests in South America and near Eucalyptus or Melaleuca plants in Australia, North America, and Europe.
Muscinupta is a fungal genus that produces small white delicate fan-shaped to cupulate fruitbodies on mosses. It is monotypic, containing the single species Muscinupta laevis. The type species is better known under the name Cyphellostereum laeve but Cyphellostereum is a basidiolichen.
An ectomycorrhiza is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota. Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture.
Neofusicoccum australe is a fungus species in the genus Neofusicoccum. It is responsible for a grapevine trunk disease.
Eonema is a fungal genus in the family Hygrophoraceae. It is monotypic, consisting of the single corticioid species Eonema pyriforme. This fungus was previously classified in the genus Athelia until molecular analysis demonstrated that it was unrelated to the Atheliales and instead nested within the Hygrophoraceae.
Dothiorella moneti is an endophytic fungus that might be a canker pathogen, specifically for Eucalyptus gomphocephala. It was isolated from said trees in Western Australia.
Dothiorella santali is an endophytic fungus that might be a canker pathogen, specifically for Eucalyptus gomphocephala. It was isolated from said trees in Western Australia.
Neofusicoccum pennatisporum is an endophytic fungus that might be a canker pathogen, specifically for Eucalyptus gomphocephala. It was isolated from said trees in Western Australia.
Trichoderma paucisporum is a species of endophytic fungus in the family Hypocreaceae. It was first isolated in Ecuador from cacao pods infected with frosty pod rot, Moniliophthora roreri. It produces a volatile antibiotic that inhibits development of M. roreri.
Fusicoccum ramosum is an endophytic fungus that might be a canker pathogen, specifically for Adansonia gibbosa (baobab). It was isolated from said trees, as well as surrounding ones, in the Kimberley.
Dothiorella longicollis is an endophytic fungus that might be a canker pathogen, specifically for Adansonia gibbosa (baobab). It was isolated from said trees, as well as surrounding ones, in the Kimberley.
Ceratocystis obpyriformis is a plant-pathogenic saprobic fungal species first found in Africa, infecting Acacia mearnsii and Eucalyptus species.
Ceratocystis tanganyicensis is a plant-pathogenic saprobic fungal species first found in Africa, infecting Acacia mearnsii and Eucalyptus species.
Ceratocystis polyconidia is a plant-pathogenic saprobic fungal species first found in Africa, infecting Acacia mearnsii and Eucalyptus species.
Diplodia allocellula is an endophytic fungus that might be a latent pathogen. It was found on Acacia karroo, a common tree in southern Africa.
