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. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants.
A sporangium ; pl.: sporangia) is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. Virtually all plants, fungi, and many other groups form sporangia at some point in their life cycle. Sporangia can produce spores by mitosis, but in land plants and many fungi, sporangia produce genetically distinct haploid spores by meiosis.
Ipomoea corymbosa is a species of morning glory, native throughout Latin America from Mexico as far south as Peru and widely naturalised elsewhere. Its common names include Christmasvine, Christmaspops, and snakeplant.
Phytophthora is a genus of plant-damaging oomycetes, whose member species are capable of causing enormous economic losses on crops worldwide, as well as environmental damage in natural ecosystems. The cell wall of Phytophthora is made up of cellulose. The genus was first described by Heinrich Anton de Bary in 1875. Approximately 210 species have been described, although 100–500 undiscovered Phytophthora species are estimated to exist.
A sorus is a cluster of sporangia in ferns and fungi. A coenosorus is a compound sorus composed of multiple, fused sori.
Vauquelinia, commonly known as the rosewoods, is a genus of the rose family, Rosaceae. It consists of two species of shrubs found in the southwestern United States and northwestern Mexico. The genus was named for French chemist Louis Nicolas Vauquelin (1763-1829). The nectar provided by these plants is commonly fed on by wasps such as Polistes instabilis.
Maranthes corymbosa is a tree in the family Chrysobalanaceae. The specific epithet corymbosa is from the Greek meaning "cluster", referring to the clustered inflorescences.
Tubifera is a genus of slime moulds from the subclass Myxogastria. The genus comprises 12 species.
Ceratiomyxa is a genus of plasmodial slime mould within the Eumycetozoa, first described by Pier Antonio Micheli. They are widely distributed and commonly found on decaying wood.
Hedeia is a genus of early land plants of uncertain affinity. It comprises erect axes terminating in corymbose clusters of erect sporangia.
Phytophthora plurivora is a very aggressive soil-borne plant pathogen, with worldwide distribution and a wide variety of hosts.
Daviesia corymbosa, also known as narrow leaf bitter pea, is a species of flowering plant in the family Fabaceae native to the state of New South Wales in eastern Australia. A shrub to 2 m (6.6 ft) high, it grows in sandstone soils in open eucalyptus woodland or heath. It produces showy flowerheads of red and yellow flowers in the spring and early summer.
Pennantia corymbosa, commonly known as kaikomako, is a small dioecious forest tree of New Zealand.
Barbeyella minutissima is a slime mould species of the order Echinosteliales, and the only species of the genus Barbeyella. First described in 1914 from the Jura mountains, its habitat is restricted to montane spruce and spruce-fir forests of the Northern Hemisphere, where it has been recorded from Asia, Europe, and North America. It typically colonises slimy, algae-covered logs that have lost their bark and have been partially to completely covered by liverworts. The sporangia are roughly spherical, up to 0.2 mm in diameter, and supported by a thin stalk up to 0.7 mm tall. After the spores have developed, the walls of the sporangia split open into lobes. The species is one of the smallest members of the Myxogastria and is considered rare.
Lobophyllia corymbosa, also known as lobed cactus coral or brain root coral, is a species of large polyp stony coral in the family Lobophylliidae. It occurs on reefs in shallow waters in the Red Sea, off the coast of East Africa, and in other parts of the tropical Indo-Pacific.
Cyathea arborea is a plant of the family Cyatheaceae in the order Cyatheales.
Tubifera ferruginosa, more commonly known as raspberry slime mold or red raspberry slime mold, is a species of slime mold in the class Myxogastria. It is one of the most widely known and distinct slime molds, being found throughout temperate regions of the world, primarily in Europe and North America.
Tubifera applanata is a species of slime mold in the class Myxogastria. It forms 2 to 7 cm wide "pseudoaethelia" that are rust-red in color. They are found growing on damp, dead wood in temperate forests, including where it was first documented, which was on a log of Pinus sylvestris in Ukraine.
Tubifera dudkae is a species of slime mold in the class Myxogastria. Unlike its relatives, T. dudkae does not form pseudoaethelia with distinct sporangia, or at least the sporangia are not visibly distinct or rod-shaped like other members of Tubifera. They are found growing on damp, dead wood in temperate forests, including where it was first documented in Ukraine. T. dudkae is found in mixed and coniferous forests across Europe and Asia
Rhynchospora corymbosa, known by the common names of golden beaksedge and matamat, is a member of the sedge family, Cyperaceae. It is a perennial herb, found globally throughout the tropics. It grows up to 2 meters tall in riverbanks, shallow pools, and swamps.
