Dimorphism of sporangia in Albuginaceae (Chromista, Peronosporomycetes)

Constantinescu O. & Thines M. (2006)

Sydowia 58 (2): 178 - 190

By using light- and scanning electron microscopy, the dimorphism of sporangia in Albuginaceae is demonstrated in 220 specimens of Albugo, Pustula and Wilsoniana, parasitic on plants belonging to 13 families. The presence of two kinds of sporangia is due to the sporangiogenesis and considered to be present in all representatives of the Albuginaceae. Primary and secondary sporangia are the term recommended to be used for these dissemination organs.

Key words: Albugo, morphology, sporangiogenesis, Pustula, Wilsoniana.
