Bovista Yasudae
''Bovista'' is a genus of fungi commonly known as the true puffballs. It was formerly classified within the now-obsolete order Lycoperdales, which, following a restructuring of fungal taxonomy brought about by molecular phylogeny, has been split; the species of ''Bovista'' are now placed in the family Agaricaceae of the order Agaricales. ''Bovista'' species have a collectively widespread distribution, and are found largely in temperate regions of the world. Various species have historically been used in homeopathic preparations. Description Fruit bodies are oval to spherical to pear-shaped, and typically in diameter with a white or light-colored thin and fragile exoperidum (outer layer of the peridium). Depending on the species, the exoperidium in a young specimen may be smooth, granular, or finely echinulate. This exoperidium sloughs off at maturity to expose a smooth endoperidium with a single apical pore (ostiole). The fruit bodies may be attached to the ground by fi ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Calbovista
''Calbovista'' is a fungal genus containing the single species ''Calbovista subsculpta'', commonly known as the sculptured puffball, sculptured giant puffball, and warted giant puffball. It is a common puffball of the Rocky Mountains and Pacific Coast ranges of western North America. The puffball is more or less round with a diameter of up to , white becoming brownish in age, and covered with shallow pyramid-shaped plates or scales. It fruits singly or in groups along roads and in open woods at high elevations, from summer to autumn. Although the puffball was originally described as new to science by Elizabeth Eaton Morse in 1935, it was not published validly until 60 years later. The species is named for its resemblance to ''Calvatia sculpta'', from which it can be usually distinguished in the field by its less prominent pyramidal warts, and microscopically by the antler-like branches of its capillitium (thread-like material among the spores). ''Calbovista subsculpta'' is a g ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Capillitium
Capillitium (pl. capillitia) is a mass of sterile fibers within a fruit body interspersed among spores. It is found in Mycetozoa (slime molds) and gasteroid fungi of the fungal subdivision Agaricomycotina The subdivision Agaricomycotina, also known as the hymenomycetes, is one of three taxa of the fungal division Basidiomycota (fungi bearing spores on basidia). The Agaricomycotina contain some 20,000 species, and about 98% of these are in the cla .... In the fungi, the form of the capillitia, including shape, size, branching patterns, presence or absence of slits or pores, thickness of the walls, and color, are features that can be used to identify certain species or genera.

Tumbleweed
A tumbleweed is a structural part of the above-ground anatomy of a number of species of plants. It is a diaspore that, once mature and dry, detaches from its root or stem and rolls due to the force of the wind. In most such species, the tumbleweed is in effect the entire plant apart from the root system, but in other plants, a hollow fruit or inflorescence might detach instead. Xerophyte tumbleweed species occur most commonly in steppe and arid ecosystems, where frequent wind and the open environment permit rolling without prohibitive obstruction. Apart from its primary vascular system and roots, the tissues of the tumbleweed structure are dead; their death is functional because it is necessary for the structure to degrade gradually and fall apart so that its seeds or spores can escape during the tumbling, or germinate after the tumbleweed has come to rest in a wet location. In the latter case, many species of tumbleweed open mechanically, releasing their seeds as they swell wh ...

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new s ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 µm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. The S ...

Mycelial Cord
Mycelial cords are linear aggregations of parallel-oriented hypha, hyphae. The mature cords are composed of wide, empty vessel hyphae surrounded by narrower sheathing hyphae. Cords may look similar to plant roots, and also frequently have similar functions; hence they are also called rhizomorphs (literally, "root-forms"). As well as growing underground or on the surface of trees and other plants, some fungi make mycelial cords which hang in the air from vegetation. Mycelial cords are capable of conducting nutrients over long distances. For instance, they can transfer nutrients to a developing fruiting body, or enable wood-rotting fungi to grow through soil from an established food base in search of new food sources. For parasitic fungi, they can help spread infection by growing from established clusters to uninfected parts. The cords of some wood-rotting fungi (like ''Serpula lacrymans'') may be capable of penetrating masonry. The mechanism of the cord formation is not yet precise ...

Ostiole
An ''ostiole'' is a small hole or opening through which algae or fungi release their mature spores. The word is a diminutive of "ostium", "opening". The term is also used in higher plants, for example to denote the opening of the involuted syconium (fig inflorescence) through which fig wasps enter to pollinate and breed. Sometimes a stoma In botany, a stoma (from Greek ''στόμα'', "mouth", plural "stomata"), also called a stomate (plural "stomates"), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange.

Echinulate
The following is a glossary of scientific terminology, terms used in the description of lichens, composite organisms that arise from algae or cyanobacteria living among Hypha, filaments of multiple fungus species in a Mutualism (biology), mutualistic relationship. Until the end of the 18th century, only a couple of lichen-specific terms had been proposed. Johann Jacob Dillenius, Johann Dillenius introduced ' in 1742 to describe the cup-shaped structures associated with genus ''Cladonia'', while in 1794 Michel Adanson used ' for the furrowed fruitbodies of the genus ''Graphis (lichen), Graphis''. Erik Acharius, the "father of lichenology", conceived many new terms to describe lichen structures in several of his seminal publications in the early 1800s. Examples include , , , , , , and . In 1825, Karl Friedrich Wilhelm Wallroth, Friedrich Wallroth published the first of his multi-volume work ''Naturgeschichte der Flechten'' ("Natural History of Lichens"), in which he proposed an alte ...
