The yeast-to-hyphae transition (filamentation) is a rapid process and induced by environmental factors. Phenotypic switching is spontaneous, happens at lower rates and in certain strains up to seven different phenotypes are known.
The yeast has a negative effect on the bacteria that normally produce antibiotics to kill the parasite, so may affect the ants' health by allowing the parasite to spread. [41] Certain strains of some species of yeasts produce proteins called yeast killer toxins that allow them to eliminate competing strains. (See main article on killer yeast ...
A branched system of slender hyphae, called the trichogyne, extends from the tip of the ascogonium projecting beyond the sheathing hyphae into the air. The sexual cycle is initiated (i.e. fertilization occurs) when a cell (usually a conidium) of opposite mating type contacts a part of the trichogyne (see figure, top of § ).

The genus Filobasidiella forms basidia on hyphae but the main infectious stage is more commonly known by the anamorphic yeast name Cryptococcus, e.g. Cryptococcus neoformans [19] and Cryptococcus gattii. [18] The dimorphic Basidiomycota with yeast stages and the pleiomorphic rusts are examples of fungi with anamorphs, which are the asexual ...
Candida albicans growing as yeast cells and filamentous (hypha) cells. A dimorphic fungus is a fungus that can exist in the form of both mold [1] and yeast.As this is usually brought about by a change in temperature, this fungus type is also described as a thermally dimorphic fungus. [2]
Blastobotrys elegans exhibits yeast like growth consisting of very dense, outwardly growing hyphae. [1] [5] It is a feminine, anamorphic ascomycete that reproduces asexually, through conidia. [5] It has no known recorded teleomorphic state. [6]
The teleomorph was first described in 1975 by K.J. Kwon-Chung, who obtained cultures of the type species, Filobasidiella neoformans, by crossing strains of the yeast Cryptococcus neoformans. She was able to observe basidia similar to those of the genus Filobasidium, hence the name Filobasidiella for the new genus. [3]
