Question: What is the scientific name of the fungus studied byby Ann Gravatt?

full_context: Document 1: Cyttaria gunnii: Cyttaria gunnii, commonly known as the myrtle orange or beech orange, is an orange-white coloured and edible ascomycete fungus native to Australasia. It is a specific parasite of myrtle beech ("Nothofagus cunninghamii") trees.
Document 2: Cenangium: Cenangium is a genus of fungi in the family Helotiaceae. The genus contains 25 species. The type species "Cenangium ferruginosum" causes dieback of pines.
Document 3: Ruth F. Allen: Ruth Florence Allen (1879–1963) was an American botanist and plant pathologist and the first woman to earn her Ph.D. in Botany from the University of Wisconsin. Her doctorate research focused on the reproduction and cell biology of ferns, particularly the phenomenon of apogamy (formation of an embryo without fertilization) (Allen, 1914). Later in her career, Dr. Allen shifted her focus to plant pathology. Her major contribution to the field of mycology was furthering the understanding of rust fungi, a group of economically important plant pathogens. Dr. Allen completed many studies on "Puccinia graminis", once considered a catastrophically damaging disease-causing agent in cereal crops before the discovery of current management measures (Schumann and Leonard, 2000).
Document 4: Bothia: Bothia is a fungal genus in the family Boletaceae. A monotypic genus, it contains the single species Bothia castanella, a bolete mushroom first described scientifically in 1900 from collections made in New Jersey. Found in the eastern United States, Costa Rica, China, and Taiwan, it grows in a mycorrhizal association with oak trees. Its fruit body is chestnut brown, the cap is smooth and dry, and the underside of the cap has radially elongated tubes. The spore deposit is yellow-brown. The edibility of the mushroom is unknown. Historically, its unique combination of morphological features resulted in the transfer of "B. castanella" to six different Boletaceae genera. Molecular phylogenetic analysis, published in 2007, demonstrated that the species was genetically unique enough to warrant placement in its own genus.
Document 5: Grosmannia clavigera: Grosmannia clavigera is a species of sac fungus that causes blue stain in wood. It spreads to lodgepole pine, ponderosa pine, Douglas-fir, and whitebark pine trees from the body and a special structure in the heads of mountain pine beetles. The blue stain fungus has evolved a relationship with mountain pine beetles that allow them to travel from tree to tree on a special structure in the beetle’s heads and stops the tree from producing resin to pitch out or kill the beetle, encouraging the pine beetle infestation occurring all along the Rocky Mountains from Mexico into Canada. The beetles are able to mine and lay eggs while avoiding the tree’s defenses. The 33 Mb genome of this fungus was sequenced in 2009.
Document 6: Chestnut blight: The pathogenic fungus Cryphonectria parasitica (formerly "Endothia parasitica") is a member of the Ascomycota (sac fungi) taxon, and is the main cause of chestnut blight—a devastating disease of the American chestnut tree that in the early 1900s caused a rapid, widespread die-off of this once plentiful tree from its historic range in the eastern United States.
Document 7: Annie Gravatt: Annie Gravatt (Annie Evelyn Rathbun) was an American forest pathologist. Her areas of research included plant physiology and white pine blister rust. She also studied Chestnut blight, the fungus that devastated American chestnut trees in the early 20th century. Along with her husband, George Gravatt, she founded the community of Scientists' Cliffs, Maryland.
Document 8: Effie A. Southworth: Effie Almira Southworth Spalding (1860–1947), was an American botanist and mycologist, and the first woman plant pathologist hired by the United States Department of Agriculture (USDA). Her most important discovery was the 1887 identification of the fungus "Colletotrichum gossypii" as the cause of cotton cankers, a disease which killed thousands of acres of cotton and was a major economic threat. She taught botany at several institutions, worked at the Desert Botanical Laboratory with her husband, and established the Botany Department Herbarium at the University of Southern California.
Document 9: Phytophthora kernoviae: Phytophthora kernoviae is a plant pathogen that mainly infects European beech ("Fagus sylvatica") and "Rhododendron ponticum". It was first identified in 2003 in Cornwall, UK when scientists were surveying for the presence of "Phytophthora ramorum". This made it the third new "Phytophthora" species to be found in the UK in a decade. It was named "Phytophthora kernoviae", after the ancient name for Cornwall, Kernow. It causes large stem lesions on beech and necrosis of stems and leaves of "Rhododendron ponticum". It is self-fertile. It has also been isolated from "Quercus robur" and "Liriodendron tulipifera". The original paper describing the species, stated it can infect "Magnolia" and "Camellia" species, "Pieris formosa", "Gevuina avellana", "Michelia doltsopa" and "Quercus ilex". Since then many other plants have been identified as natural hosts of the pathogen. Molecular analysis has revealed that an infection on "Pinus radiata", recorded in New Zealand in 1950, was caused by "P. kernoviae".
Document 10: Cryphonectria: Cryphonectria is a fungal genus in the order Diaporthales. The most well-known and well-studied species in the genus is "Cryphonectria parasitica", the species which causes chestnut blight. The genus was, for a time, considered synonymous with "Endothia", but the two are now recognised as distinct. Taxonomic studies in 2006 limited the genus to four species, but a fifth, "Cryphonectria naterciae", was described in 2011 from Portugal.
Document 11: Dryocosmus kuriphilus: Dryocosmus kuriphilus is a species of gall wasp known by the common names chestnut gall wasp, Oriental chestnut gall wasp, and Asian chestnut gall wasp. It is native to China and it is known in many other parts of the world, particularly the Northern Hemisphere, as an introduced species and an invasive horticultural pest. It attacks many species of chestnut (genus "Castanea"), including most cultivated varieties. It is considered the world's worst pest of chestnuts.
Document 12: Leucostoma canker: Leucostoma canker is a fungal disease that can kill stone fruit ("Prunus" spp.). The disease is caused by the plant pathogens "Leucostoma persoonii" and "Leucostoma cinctum" (teleomorph) and "Cytospora leucostoma" and "Cytospora cincta" (anamorphs). The disease can have a variety of signs and symptoms depending on the part of the tree infected. One of the most lethal symptoms of the disease are the Leucostoma cankers. The severity of the Leucostoma cankers is dependent on the part of the plant infected. The fungus infects through injured, dying or dead tissues of the trees. Disease management can consist of cultural management practices such as pruning, late season fertilizers or chemical management through measures such as insect control. Leucostoma canker of stone fruit can cause significant economic losses due to reduced fruit production or disease management practices. It is one of the most important diseases of stone fruit tree all over the world.
Document 13: Sphaeropsis blight: Sphaeropsis blight is a disease that affects pines worldwide. This disease was previously known as Diplodia tip blight. Sphaeropsis blight is considered to be a "disfiguring disease" that attacks pine trees that are growing under stressful conditions. Sphaeropsis blight does not typically kill the tree, but will significantly disfigure the tree if not properly cared for or controlled. Most commonly, Sphaeropsis blight attacks Austrian ("Pinus nigra"), Scots ("P. sylvestris"), and red ("P. resinosa") pine trees. This disease is a problem in the United States, nationwide, from coast to coast, and can be found worldwide.
Document 14: Chestnut: The chestnut group is a genus (Castanea) of eight or nine species of deciduous trees and shrubs in the beech family Fagaceae, native to temperate regions of the Northern Hemisphere.
Document 15: Pine-pine gall rust: Pine-pine gall rust, also known as western gall rust, is a fungal disease of pine trees. This plant disease is caused by Endocronartium harknessii (asexual name is "Peridermium harknessii"), an autoecious, endocyclic, rust fungus that grows in the vascular cambium of the host. Pine-pine gall rust is found on pine trees ("Pinus" spp.) with two or three needles such as ponderosa pine, jack pine, and scots pine. The disease is very similar to pine-oak gall rust, but its second host is another "Pinus" species. The fungal infection results in gall formation on branches or trunks of infected hosts. Gall formation is typically not detrimental to old trees but has been known to kill younger less stable saplings. Galls can vary from small growths on branch extremities to grapefruit sized galls on trunks.
