What does Arthrospore mean?
What does Arthrospore mean?
sporelike cell
arthrospore. / (ˈɑːθrəˌspɔː) / noun. a sporelike cell of ascomycetous fungi and some algae produced by a breaking of the hyphae. a resting sporelike cell produced by some bacteria.
Do Arthrospores carry asexual spores?
Most molds are capable of both sexual and asexual reproduction. Asexual reproduction can occur either by central constriction of a parent cell to form two daughter cells or by spore formation. There are several types of spore formation. When hyphal fragementation occurs, the resulting spores are termed arthrospores.
Is the hyphae septate or Unseptate?
Hyphae that have walls between the cells are called septate hyphae; hyphae that lack walls and cell membranes between the cells are called nonseptate or coenocytic hyphae), As hyphae continue to grow, they form a tangled network called a mycelium.
Does Coccidioides immitis produce Arthrospores?
The laboratory diagnosis of Coccidioides immitis revolves around differentiation of the fungus from other species that produce arthrospores by hyphal segmentation. These include most notably Malbranchea, Geotrichum candidum, Oospora, and Gymnoascaceae species.
What is Phaeoid?
Phaeohyphomycosis refers to infections of skin, subcutaneous tissues, and internal organs caused by dematiaceous (phaeoid) fungi. These fungi produce pigmented hyphae and/or yeast-like cells in culture and frequently in the infected tissue.
Do mushrooms form arthrospores?
Most of the basidiomycetes (mushrooms) form arthrospores as part of their mycelial phase; these arthrospores are not distinctive and are for the most part not an aid in identification. Colonies isolated on Andersen samples with aerial mycelia and many arthrospores are most probably the result of germinating basidiospores from mushrooms.
Do all basidiomycetes fruit on laboratory media?
Most Basidiomycetes will not fruit on laboratory media. Many will form arthrospores or sterile mycelia on laboratory media. Most basidiospores have a distinctive asymmetrical attachment point. Many basidiomycetes have recognizable spores.
Can basidiospores be found on tape lifts?
Except for the occasional finding of Serpula (above), basidiospores are rarely found on tape lifts, except as a part of normal influx of outdoor spores.
How many types of fungi are there in the Basidiomycota?
The Basidiomycota division branches off into three subdivisions and two classes. The subdivision Agaricomycotina contains around 20,000 species of fungi, nearly 90% of which belong to the class Agaricomycetes. Types of fungi found in Agaricomycotina: Gilled Mushrooms, Polypores, Corals, Chanterelles, Crusts, Puffballs, and Stink Horns.
