Within the United States, approximately 13,000 species of microfungi on plants or plant products are thought to exist. Specimens of microfungi are housed in the U.S. National Fungus Collections and other institutions like herbaria and culture collections that serve as reservoirs of information and documentation about the nation's natural heritage.
White mold affects a wide range of hosts and causes sclerotinia stem rot. It is known to infect 408 plant species. As a nonspecific plant pathogen, [2] diverse host range and ability to infect plants at any stage of growth makes white mold a serious disease. The fungus can survive on infected tissues, in the soil, and on living plants.
S. chartarum is a slow-growing mold that does not compete well with other molds. It is only rarely found in nature, sometimes being found in soil and grain, but is most often detected in cellulose-rich building materials, such as gypsum-based drywall and wallpaper from damp or water-damaged buildings.
A. niger growing on potato dextrose agar. A. niger is a strict aerobe; therefore, it requires oxygen to grow. [11] The fungus can grow in a range of environmental conditions; it can grow at temperatures ranging from 6 to 47 °C. [12] As a mesophile, [13] its optimal temperature range is 35-37 °C. [11] It can tolerate pH ranging from 1.5 to 9.8 ...
Species in the genus are commonly found in soil, plant litter (hay, straw, cereal grains, and decaying plant debris) and air and a few species have been found from damp paper, cotton, linen, cellulose-based building materials water-damaged indoor buildings, and air ducts from both aquatic and terrestrial habitats (Izabel et al. 2010; [6 ...
Sooty mold is commonly seen on the leaves of ornamental plants such as azaleas, gardenias, camellias, crepe myrtles, Mangifera and laurels. Karuka is affected by sooty mold caused by Meliola juttingii. [6] Plants located under pecan or hickory trees are particularly susceptible to sooty mold, because honeydew-secreting insects often inhabit ...
Cladosporium fulvum is an Ascomycete called Passalora fulva, a non-obligate pathogen that causes the disease on tomatoes known as the tomato leaf mold. [1] P. fulva only attacks tomato plants, especially the foliage, and it is a common disease in greenhouses, but can also occur in the field. [2] The pathogen is likely to grow in humid and cool ...
Peronospora hyoscyami f.sp. tabacina is a plant pathogen infecting tobacco that causes blue mold. It is an oomycete (a fungus-like organism) that is highly destructive toward seed plants. It is very prevalent in humid farming zones, like the southeastern and Eastern U.S. , Canada , and countries bordering the Caribbean .
