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 ...
Aerial photograph interpretation is a method of extrapolating geological details of the ground surface from aerial images. [1] It allows geologists to analyze the distinguishing geological features and structures , plant cover , past history of the site, soil properties, and topography of the study area.
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.
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
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 ...
[4] [7] [6] Conidia are typically produced only at the interface of the medium surface and the air, and are rarely present on submerged or aerial hyphae. [ 4 ] [ 7 ] Phialemonium obovatum grows optimally between 24–33 °C (75–91 °F) although it can grow at temperatures as low as 15 °C (59 °F) and as high as 40 °C (104 °F).
A more precise definition has been suggested by Aptroot and Lücking, who propose that the term applies to ascomata and pseudostromata that are more than 1/2 to 3/4 above the level of the thallus. [181] esorediate Also esorediose. Lacking soredia. [182] eucortex Plural eucortices or eucortexes. A cortex made of well-differentiated tissue. [183]
