CHARACTERISTICS OF FUNGI Spores are formed from aerial hyphae in various ways, and can be sexual or asexual.  a. Asexual spores—formed by the hyphae of one organism. When these germinate, the organism  they produce is genetically identical to the original. They are produced by mitosis and cell  division. Types: 1) Conidiospores—unicellular or multicellular spores not enclosed in a sac. They are produced in  a chain at the end of a stalk-like conidiophore.  Aspergillus  is an example. Two special types of  conidiospores: a) Arthrospore—fragmentation of a septate hypha into single cells.  Coccidiodes immitis  is an  example. b) Blastoconidia—special type of conidiospore that consist of buds coming off the parent cell.  Candida albicans  and  Cryptococcus  are examples. 2) Chlamydospores—thick-walled spore formed by rounding and enlargement within a hyphal  segment.
