C. albicans exhibits a wide range of morphological phenotypes due to phenotypic switching and bud to hypha transition. 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.
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]
Cryptococcus is a genus of fungi in the family Cryptococcaceae that includes both yeasts and filamentous species.The filamentous, sexual forms or teleomorphs were formerly classified in the genus Filobasidiella, while Cryptococcus was reserved for the yeasts.
In the environment it is found growing as filamentous hyphae. In host tissue it is found as a yeast. The transition between the hyphal and yeast forms is temperature dependent making S. schenckii a thermally dimorphic fungus. [1]
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).
Malassezia furfur is a fungus that lives on the superficial layers of the dermis.It generally exists as a commensal organism forming a natural part of the human skin microbiota, but it can gain pathogenic capabilities when morphing from a yeast to a hyphal form during its life cycle, through unknown molecular changes.

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 ...
A blastoconidium (plural blastoconidia) is an asexual holoblastic conidia formed through the blowing out or budding process of a yeast cell, which is a type of asexual reproduction that results in a bud arising from a parent cell. [1] [2] The production of a blastoconidium can occur along a true hyphae, pseudohyphae, or a singular yeast cell. [3]
