In addition to having septate basidia, heterobasidiomycetes also frequently possess large irregularly shaped sterigmata and spores that are capable of self-replication – a process where a spore, instead of germinating into a vegetative hypha, gives rise to a sterigma and a new spore, which is then discharged as if from a normal basidium. In ...
Aseptate (non-septate) or coenocytic (without septa) Non-septate hyphae are associated with Mucor , [ 9 ] some zygomycetes , and other fungi. Pseudohyphae are distinguished from true hyphae by their method of growth, relative frailty and lack of cytoplasmic connection between the cells.
The hyphae of Cladosporium sphaerospermum are thick walled, septate, and olivaceous-brown in colour. [5] Colonies of the fungus are velvety in texture and flattened (i.e., rarely raised, fluffy, or radially furrowed). C. sphaerospermum conidiophores are branched, septate, and dark, up to 150–300 μm long and 3.5–4.0 μm wide. [5]
In some smuts such as Mycosarcoma maydis the nuclei migrate into the promycelium that becomes septate (i.e., divided into cellular compartments separated by cell walls called septa), and haploid yeast-like conidia/basidiospores sometimes called sporidia, bud off laterally from each cell. In various smuts, the yeast phase may proliferate, or ...
Dark septate endophytes are plant root-colonizing fungi that are often darkly-pigmented, with septate hyphae, and form structures inside plant root cells such as microsclerotia. However, there is great variation in morphology within this group. Dark septate endophytes are observed more frequently in mature parts of the root system. [3]
Structure of a septate (right) and aseptate (left) eugregarine Gregarina garnhami is a gregarine that belongs to the septate eugregarines , meaning its cell is separated into parts. In G. garnhami , three parts can be seen: epimerite, protomerite, and deutomerite, but their visibility depends on the lifestage of the organism.
The Glomeromycota have generally coenocytic (occasionally sparsely septate) mycelia and reproduce asexually through blastic development of the hyphal tip to produce spores [2] (Glomerospores,blastospore) with diameters of 80–500 μm. [9] In some, complex spores form within a terminal saccule. [2]
In the aseptate (or acephalate) species the cell is not divided. In the septate (or cephalate) species the body is divided into at least 2 parts: a posterior portion which contains the nucleus (the deutomerite) and an anterior portion (the protomerite), which forms the epimerite. In some species the deutomerite may be further subdivided.
