They have few septa and lack clamp connections. Fusiform skeletal hyphae are the second form of skeletal hyphae. Unlike typical skeletal hyphae these are swollen centrally and often exceedingly broad, hence giving the hypha a fusiform shape. Binding hyphae are thick-walled and frequent branched. Often they resemble deer antlers or defoliated ...
Although the mycelia and the aerial hyphae that arise from them are amotile, mobility is achieved by dispersion of spores. [16] Spore surfaces may be hairy, rugose, smooth, spiny or warty. [ 17 ] In some species, aerial hyphae consist of long, straight filaments, which bear 50 or more spores at more or less regular intervals, arranged in whorls ...
Mycelial cords are linear aggregations of parallel-oriented 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 ...
Hyaloperonospora parasitica: hyphae and haustoria Haustoria of creeping mistletoe in a scribbly gum A coconut sprout, the edible haustorium of germinating coconut seeds. In botany and mycology, a haustorium (plural haustoria) is a rootlike structure that grows into or around another structure to absorb water or nutrients.
Nocardia colonies have a variable appearance, but most species appear to have aerial hyphae when viewed with a dissecting microscope, particularly when they have been grown on nutritionally limiting media. Nocardia grow slowly on nonselective culture media, and are strict aerobes with the ability to grow in a wide temperature range.
Mycelium (pl.: mycelia) [a] is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. [1] Its normal form is that of branched, slender, entangled, anastomosing, hyaline threads. [2] Fungal colonies composed of mycelium are found in and on soil and many other substrates.
Hyphae that lack septa and are multi-nucleate; seen in Zygomycota and Oomycota. From Gr. kytos, cell. Distinct from a synctium, a multinucleate structure resulting from fusion of protoplasts. [69] colony A massed group of hyphae and spores of a single species, especially if all are grown from a single spore (e.g. in a lab). [70] columella. pl ...
Some bacteria, while still reproducing asexually, form more complex reproductive structures that help disperse the newly formed daughter cells. Examples include fruiting body formation by myxobacteria and aerial hyphae formation by Streptomyces species, or budding. Budding involves a cell forming a protrusion that breaks away and produces a ...
