Phyllachora banksiae is a species of fungus in the family Phyllachoraceae. Originally named Plectosphaera banksiae by Harry Swart, [1] it was placed in the genus Phyllachora in 2001. [2] The type collection was made from a Banksia integrifolia plant in Lake Tyers, Victoria (Australia) in May, 1986. Infection is characterised by leaf spots that have a greyish central area spotted with black ostioles (pores) through which spores are expelled. The mycelium of the fungus grows in the double-layered epidermis of the leaf of the host plant, and penetrates the mesophyll tissue in the center of the colony. Perithecia are up to 400 μm in diameter and are the same thickness as the leaf. The asci (spore-bearing cells) are up to 180 μm long and 15 μm wide. Ascospores are hyaline (translucent), and measure 20–25 by 10 μm. [1]
Rusts are fungal plant pathogens of the order Pucciniales causing plant fungal diseases.
Banksia coccinea, commonly known as the scarlet banksia, waratah banksia or Albany banksia, is an erect shrub or small tree in the family Proteaceae. Its distribution in the wild is along the south west coast of Western Australia, from Denmark to the Stokes National Park, and north to the Stirling Range, growing on white or grey sand in shrubland, heath or open woodland. Reaching up to 8 m (26 ft) in height, it is a single-stemmed plant that has oblong leaves, which are 3–9 cm (1.2–3.5 in) long and 2–7 cm (0.8–2.8 in) wide. The prominent red and white flower spikes appear mainly in the spring. As they age they develop small follicles that store seeds until opened by fire. Though widely occurring, it is highly sensitive to dieback and large populations of plants have succumbed to the disease.
Hemileia vastatrix is a multicellular basidiomycete fungus of the order Pucciniales that causes coffee leaf rust (CLR), a disease affecting the coffee plant. Coffee serves as the obligate host of coffee rust, that is, the rust must have access to and come into physical contact with coffee in order to survive.
Banksia marginata, commonly known as the silver banksia, is a species of tree or woody shrub in the plant genus Banksia found throughout much of southeastern Australia. It ranges from the Eyre Peninsula in South Australia to north of Armidale, New South Wales, and across Tasmania and the islands of Bass Strait. It grows in various habitats, including Eucalyptus forest, scrub, heathland and moorland. Banksia marginata varies widely in habit, ranging from a 20-centimetre (7.9 in) shrub to a 12-metre (40 ft) tree. The narrow leaves are linear and the yellow inflorescences occur from late summer to early winter. These flower spikes fade to brown and then grey and develop woody follicles bearing the winged seeds. Originally described by Antonio José Cavanilles in 1800, further collections of B. marginata were designated as several separate species by Robert Brown in 1810. However, all were reclassified as a single species by George Bentham in 1870. No distinct subspecies have been recognised by Banksia expert Alex George, who nonetheless concedes that further work is needed.
Banksia speciosa, commonly known as the showy banksia, is a species of large shrub or small tree in the family Proteaceae. It is found on the south coast of Western Australia between Hopetoun (33°57′ S) and the Great Australian Bight, growing on white or grey sand in shrubland. Reaching up to 8 m (26 ft) in height, it is a single-stemmed plant that has thin leaves with prominent triangular "teeth" along each margin, which are 20–45 cm (7.9–17.7 in) long and 2–4 cm (0.8–1.6 in) wide. The prominent cream-yellow flower spikes known as inflorescences appear throughout the year. As they age they develop up to 20 follicles each that store seeds until opened by fire. Though widely occurring, the species is highly sensitive to dieback and large populations of plants have succumbed to the disease.
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.
Omphalotus nidiformis, or ghost fungus, is a gilled basidiomycete mushroom most notable for its bioluminescent properties. It is known to be found primarily in southern Australia and Tasmania, but was reported from India in 2012 and 2018. The fan or funnel shaped fruit bodies are up to 30 cm (12 in) across, with cream-coloured caps overlain with shades of orange, brown, purple, or bluish-black. The white or cream gills run down the length of the stipe, which is up to 8 cm (3 in) long and tapers in thickness to the base. The fungus is both saprotrophic and parasitic, and its fruit bodies are generally found growing in overlapping clusters on a wide variety of dead or dying trees.
Silver leaf is a fungal disease of trees caused by the fungal plant pathogen Chondrostereum purpureum. It attacks most species of the rose family Rosaceae, particularly the genus Prunus. The disease is progressive and often fatal. The common name is taken from the progressive silvering of leaves on affected branches. It is spread by airborne spores landing on freshly exposed sapwood. For this reason cherries and plums are pruned in summer, when spores are least likely to be present and when disease is visible. Silver Leaf can also happen on poming fruits like apples and pears. Plums are especially vulnerable.
Zymoseptoria tritici, synonyms Septoria tritici, Mycosphaerella graminicola, is a species of filamentous fungus, an ascomycete in the family Mycosphaerellaceae. It is a wheat plant pathogen causing septoria leaf blotch that is difficult to control due to resistance to multiple fungicides. The pathogen today causes one of the most important diseases of wheat.
Mycena galopus, commonly known as the milky mycena, milking bonnet or milk-drop mycena, is an inedible species of fungus in the family Mycenaceae of the order Agaricales. It produces small mushrooms that have grayish-brown, bell-shaped, radially-grooved caps up to 2.5 cm (1 in) wide. The gills are whitish to gray, widely spaced, and squarely attached to the stem. The slender stems are up to 8 cm (3 in) long, and pale gray at the top, becoming almost black at the hairy base. The stem will ooze a whitish latex if it is injured or broken. The variety nigra has a dark gray cap, while the variety candida is white. All varieties of the mushroom occur during summer and autumn on leaf litter in coniferous and deciduous woodland.
Macrolepiota clelandii, commonly known as the slender parasol or graceful parasol, is a species of mushroom-forming fungus in the family Agaricaceae. The species is found in Australia and New Zealand, where it fruits singly or in small groups on the ground in eucalypt woodlands, parks, and roadsides. It is a tall mushroom up to roughly 20 cm (8 in), with a broad cap covered with distinctive rings of dark brown scales. The whitish gills on the cap underside are closely spaced and free from attachment to the slender stipe, which has a loose ring on its upper half, and a bulbous base. The edibility of the mushroom is not known with certainty, but closely related parasol mushrooms are edible and some are very sought after.
Banksiamyces is a genus of fungi in the order Helotiales, with a tentative placement in the family Helotiaceae. The genus contains four species, which grow on the seed follicles of the dead infructescences or "cones" of various species of Banksia, a genus in the plant family Proteaceae endemic to Australia. Fruit bodies of the fungus appear as small, shallow dark cups on the follicles of the Banksia fruit. The edges of dry fruit bodies fold inwards, appearing like narrow slits. The first specimens of Banksiamyces, known then as Tympanis toomansis, were described in 1887. Specimens continued to be collected occasionally for almost 100 years before becoming examined more critically in the early 1980s, leading to the creation of a new genus to contain what was determined to be three distinct species, B. katerinae, B. macrocarpus, and B. toomansis. A fourth species, B. maccannii, was added in 1984.
Phyllachora is a genus of fungi in the family Phyllachoraceae. An Outline of Fungi in 2020 listed up to 1513 species.
Lineostroma is a genus of fungi in the family Venturiaceae; according to the 2007 Outline of Ascomycota, the placement in this family is uncertain. A monotypic genus, it contains the single species Lineostroma banksiae.
Westea is a genus of fungi in the class Dothideomycetes. The relationship of this taxon to other taxa within the class is unknown. A monotypic genus, it contains the single species Westea banksiae, which grows on Banksia trees in Australia. Described by South African botanist Haring Johannes 'Harry' Swart, it was originally collected from the leaves of Banksia integrifolia in Victoria.
Noosia is a fungal genus in the division Ascomycota. The genus is monotypic, containing the single anamorphic species Noosia banksiae. The fungus is associated with brown leaf spots on the wallum banksia, an Australian shrub of the family Proteaceae. The conidia of the fungus are dimorphic. They are initially spherical, smooth and somewhat hyaline; later they become fusoid to ellipsoidal, brown, and covered in small warts. The generic name Noosia refers to the town Noosa, where the type collection was made, in Noosa National Park; the specific epithet refers to the generic name of the host plant.
Septoria musiva, correct taxonomic name: Sphaerulina musiva, is an ascomycete fungus responsible of a leaf spot and canker disease on poplar trees. It is native on the eastern cottonwood poplar Populus deltoides, causing only a leaf spot symptom. On susceptible hybrid poplars, S. musiva causes necrotic lesions on the leaves which lead to premature defoliation, and cankers on the stem and branches which can reduce growth, predispose the tree to colonisation by secondary organisms, and cause stem breakage.
Brunneocarpos is a fungal genus in the family Mycocaliciaceae. It is a monotypic genus, containing the single species Brunneocarpos banksiae. The fungus grows on the cones of Banksia plants in Australia.
Trabutiella is a genus of fungi in the family Phyllachoraceae.
Linochora is a genus of fungi in the family Phyllachoraceae.
