''Apophlaea'' is a genus of thalloid algae comprising two species, both from the high intertidal zone on New Zealand's coasts. Specimens can reach around 15 cm in size. The thalli take a crustose form, but also contain upright, branching frond-like protrusions that reach 5–8 cm in height. Secondary pit connections and secondary pit connectionsare present in the organisms. ''Apophlaea'' reproduces by means of conceptacles; it produces tetraspores. It is notable for its symbiotic relationship with certain fungi. Despite its unusual morphology, molecular systematics, along with its zoned tetrasporangia borne in conceptacles with a single opening, place it within the Hildenbrandiales. The algae are resistant to both U-V radiation and desiccation, allowing them to thrive in intertidal settings. Indeed, they can resume almost full photosynthesis just minutes after losing 95% of their tissue water. == External links == * Images are available at : * http://thinkoholic.com/pic.php?l=de&resize=1&s=396&img=4194 * http://www.seafriends.org.nz/enviro/habitat/rsred.htm 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Apophlaea」の詳細全文を読む スポンサード リンク
