Blastocladia is a genus of aquatic fungi.
Blastocladia species have a thallus that consists of a single, branched basal cell or trunk with rhizoids at one end and sporangia at the other. They are not able to use oxygen, although its presence does not inhibit growth.[1]
Members of Blastocladia grow on submerged twigs and fruit.[1]
Blastocladia was circumscribed by German scientist Paul Friedrich Reinsch in 1877, who included a single species, Blastocladia pringsheimii.[2] Roland Thaxter added a second species, B. ramosa in 1896. He placed the genus provisionally in the Pythiaceae owing to its resemblance of its resting spores to the conidia of some members of the genus Pythium.[3] Joseph Schröter (1897) included it with the water mold family Leptomitaceae.[4]
As of December 2015, Index Fungorum accepts 30 species in Blastocladia:[5]

芽枝霉屬(學名:Blastocladia)為芽枝黴門下的一個屬,為水生真菌。
芽枝霉屬的菌體型態為一端以單個主幹基礎上產生分支並具有假根,另一端則為孢子囊所組成,形似一棵樹。芽枝霉屬是耐氧生物,無法利用氧氣,但氧氣的存在不會抑制牠們的生長。[1] 菌體無隔板及假隔板,以假根附著在基質上,細胞壁成分為聚糖-幾丁質。動孢子(英语:zoospore)於囊上的單一乳突釋放,游走孢子具後生單一鞭毛,並有核冠。[2]
芽枝霉屬一般生長於在沉入水中的樹枝或果實上,營養方式為腐生。[1]
芽枝霉屬於1877年由德國生物學家保羅·弗里德里克·芮恩施(英语:Paul Friedrich Reinsch)發表,當時只包含一個物種布寧芽枝黴(Blastocladia pringsheimii)[3]。而後美國真菌學家羅蘭·瑟斯特(英语:Roland Thaxter)於1896年加入第二個物種多枝芽枝黴(B. ramosa),他因本屬物種的休眠孢子(英语:Resting spore)與部分腐霉属(英语:Pythium)物種的分生孢子相似,而將本屬歸入腐霉科(英语:Pythiaceae)之下[4]。德國真菌學家約瑟夫·梭羅德(英语:Joseph Schröter)於1897年則將其歸類於水黴菌的一科根壶菌科(英语:Leptomitaceae)中。[5]
截至2015年12月 (2015-12)[update],Index Fungorum中共記載了本屬的30種物種[6]
