In most fungi the vegetative system for exploitation of the substrate is composed of thread-like filaments called hyphae.  In Yeast  fungi, however, the vegetative system is composed of single cells.  These reproduce by a method called budding.  A blip at one or both ends (and sometimes from the sides) of a cell grows out and enlarges until it is as large as the parent cell;  then it breaks away.   The process is repeated again and again.   Yeasts do best in free water or in very moist environments.
