=Types of Fungi=

There are two principle types of fungi, the moulds and the yeasts. fungal '''hyphae''' are the branching tubular structures of moulds which become entwined as the fungi grows to form a '''mycelium'''. Hyphae are divided by cross walls into '''septa'''. There are arial (above the surface) and surface hyphae. The aerial hyphae produce spores which are reproductive fungal cells. There are two main types of spore produced,  '''conidiospores''' and '''sporangiospores'''. These produce asexual spores called '''conidia''' which are relatively resistant to physical and chemical agents.

The yeasts range from 3µm to 5µm and are oval or spherical cells. '''Pseudohyphae''' are produced by some yeasts which are chains of irregular yeast cells. '''Dimorphic fungi''' change from the mycelial form into yeasts in certain conditions, e.g. 37°C or when inside animal tissue.
