Echinopsis is a large genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. One small species, E. chamaecereus, is known as the peanut cactus. The 128 species range from large and treelike types to small globose cacti. The name derives from echinos hedgehog or sea urchin, and opsis appearance, a reference to these plants' dense coverings of spines.
Goodyera repens, an orchid in the genus Goodyera, is called by the common name creeping lady's-tresses in Anglophone Europe and dwarf rattlesnake plantain or lesser rattlesnake plantain in North America.
Damping off is a horticultural disease or condition, caused by several different pathogens that kill or weaken seeds or seedlings before or after they germinate. It is most prevalent in wet and cool conditions.
Herpsilochmus is a genus of insectivorous passerine birds in the antbird family (Thamnophilidae). They are found in forest, woodland and shrub in South America, although a single species the rufous-winged antwren also occurs in Panama. All are relatively small antbirds that are sexually dichromatic. In most species males are essentially light grey with a black crown and black-and-white wings, while females are more buff or rufous with black-and-white crown.
Liriope spicata is a species of low, herbaceous flowering plant from East Asia. Common names include creeping lilyturf, creeping liriope, lilyturf, and monkey grass. This perennial has grass-like evergreen foliage and is commonly used in landscaping in temperate climates as groundcover. Creeping lilyturf has white to lavender flowers which produce single-seeded berries on a spike in the fall. It is one of the most popular groundcovers in the southeastern United States and areas with a similar climate.
Ancylostoma braziliense is a species of hookworm belonging to the genus Ancylostoma. It is an intestinal parasite of domestic cats and dogs. Severe infection is often fatal to these pets, especially in puppies and kittens. The infection is particularly endemic in the southern United States. It is most often confused with the zoonotic hookworm species Ancylostoma ceylanicum because of their uncanny resemblance.
Lindquistomyces is a fungal genus in the family Amphisphaeriaceae. This is a monotypic genus, containing the single species Lindquistomyces antarcticus. This species was originally described as Ophiobolus antarcticus by Carlos Luigi Spegazzini in 1887.
Liriope muscari is a species of low, herbaceous flowering plants from East Asia. Common names in English include big blue lilyturf, lilyturf, border grass, and monkey grass. It is a perennial with grass-like evergreen foliage and lilac-purple flowers which produce single-seeded berries on a spike in the fall.
Cosmopterix is a large genus of moth in the family Cosmopterigidae.
Oudemansiella is a genus of fungi in the family Physalacriaceae. According to the Dictionary of the Fungi, the genus contains about 15 species that are widely distributed in tropical and temperate regions. Yang and colleagues revised the genus in a 2009 publication, describing several new species and several varieties. They classified species in the genus into four sections based on the structure of the cap cuticle: Oudemansiella, Mucidula, Dactylosporina, and Radicatae.
Neonothopanus nambi is a poisonous and bioluminescent mushroom in the family Marasmiaceae. The genetic and molecular mechanisms underlying this species' bioluminescence were published in 2019, the first to be elucidated for a fungus. In 2020, genes from this fungus were used to create bioluminescent tobacco plants.
Pseudocercospora is a genus of ascomycete fungi. An anamorphic version of the genus Mycosphaerella, Pseudocercospora species are plant pathogens. The widely distributed genus has been estimated to contain over 1100 species, concentrated predominantly in tropical regions. Pseudocercospora was circumscribed by Italian-Argentinian botanist Carlos Luigi Spegazzini in 1910.
Ceratobasidium is a genus of fungi in the order Cantharellales. Basidiocarps are effused and the genus is sometimes grouped among the corticioid fungi, though species also retain features of the heterobasidiomycetes. Rhizoctonia-like anamorphs of Ceratobasidium species are placed in the genus Ceratorhiza. Species are saprotrophic, but several are also facultative plant pathogens, causing a number of commercially important crop diseases. Some are also endomycorrhizal associates of orchids.
Dollar spot is caused by the four species in the genus Clarireedia, in the family Rutstroemiaceae. The pathogen blights leaf tissues but does not affect turf grass roots or crowns. The disease is a common concern on golf course turf, but is rare in sports turf and professional landscapes. Disease symptoms commonly result in poor turf quality and appearance. The disease occurs from early spring through late fall, but is most active under conditions of high humidity and warm daytime temperatures 59–86 °F (15–30 °C) and cool nights in the spring, early summer and fall. The disease infects by producing a mycelium, which can be spread mechanically from one area to another.
Pestalotiopsis microspora is a species of endophytic fungus capable of breaking down and digesting polyurethane. Originally identified in fallen foliage of common ivy in Buenos Aires, it also causes leaf spot in Hypericum 'Hidcote' shrubs in Japan.
Coccomyces dentatus is a species of fungus in the family Rhytismataceae. A widespread species, particularly in temperate areas, it colonizes the dead fallen leaves of vascular plants, particularly oak and chestnut. The fungus apothecia, which form in the epidermal layer of the leaf host, resemble dark hexagonal spots scattered on a multi-colored mosaic pattern bounded by thin black lines. When mature, the apothecia open by triangular flaps to release spores. The anamorph form of C. dentatus is Tricladiopsis flagelliformis. Lookalike species can be distinguished by the shape of the apothecia, or by microscopic characteristics.
Oudemansiella mucida, commonly known as porcelain fungus, is a basidiomycete fungus of the family Physalacriaceae and native to Europe.
Necrotic ring spot is a common disease of turf caused by soil borne fungi that mainly infects roots (4). It is an important disease as it destroys the appearance of turfgrasses on park, playing fields and golf courses. Necrotic Ring Spot is caused by a fungal pathogen that is an ascomycete that produces ascospores in an ascocarp (6). They survive over winter, or any unfavorable condition as sclerotia. Most infection occurs in spring and fall when the temperature is about 13 to 28°C (5). The primary hosts of this disease are cool-season grasses such as Kentucky bluegrass and annual bluegrass (6). Once turf is infected with O. korrae, it kills turf roots and crowns. Symptoms of the disease are quite noticeable since they appear as large yellow ring-shaped patches of dead turf. Management of the disease is often uneasy and requires application of multiple controls. The disease can be controlled by many different kind of controls including chemicals and cultural.
Lentinula guarapiensis is a species of agaric fungus in the family Marasmiaceae that is found in Paraguay. Originally described by Carlos Luigi Spegazzini in 1883 as Agaricus guarapiensis, it was moved to the genus Lentinula by David Pegler in 1983. It is only known from the type collection.
Iris acutiloba is a species in the genus Iris, it is also in the subgenus of Iris and Oncocyclus Section. It is a rhizomatous perennial, from the mountains of the Caucasus and found in Turkey, Armenia, Azerbaijan, Turkmenistan, Dagestan in the North Caucasus, and Iran. It is a dwarf species, with narrow, falcate or curved leaves, it has one flower in spring or early summer, that comes in shades from cream, creamy white, whitish, pale brown, light grey, to pale violet. It is heavily veined or streaked and pointed, with 2 dark spots and brown, purple, dark purple, or black short beard. It is cultivated as an ornamental plant in temperate regions. There are two subspecies, Iris acutiloba subsp. lineolata and Iris acutiloba subsp. longitepala.
