Abstract

A new aerophytic species of the xanthophycean genus Excentrochloris Excentrochloris fraunhoferiana Hofbauer, Gärtner, Rennebarth, Sedlbauer, Mayer et Breuer from a building surface is described. Light microscopically investigation and sequence analyses showed a clear relationship of the new alga to Botrydiopsis constricta Broady. Cytomorphology and reproduction of the new species was investigated on cultures. E. fraunhoferiana differs from the type species E. gigas by bigger size of adult vegetative cells with obligate thickening of wall, and none amoeboid zoospores with one chloroplast. Adult zoospores are peripherically arranged in the sporangia. The relation to Botrydiopsis constricta is discussed in comparison with characters of E. fraunhoferiana.
