湖北大学校园内的气生和亚气生绿藻

THE AERIAL AND SUBAERIAL ALGAE FROM THE CAMPUS OF HUBEI UNIVERSITY, WUHAN, HUBEI

作者近两年(1989～1991)在本校校园中采得气生和亚气生藻类标本25号(及另一些未列号者),其中采自10种树木树皮上的,和采自潮湿地面、石块、砖块、水泥台阶、墙壁及花盆外壁的约各占一半。本文先报道已经鉴定过的绿藻14属21种,其中我国新记录共9种。 这些绿藻的名称如下:钝顶纤维藻(Ankistrldesmus oldusus),虚幻球藻(Apotococcus Woatus),土生绿球藻(Chlorococum humicola),小球藻(Chorella vulgaris),椭圆小球藻(C.ellipsbidea),光滑鼓藻(Cosmarium laeve)钝鼓藻(C.oblastum),柱胞鼓藻(Cylindrocystis lrelissunii),链丝藻(Hormiduum flaocidum),深裂链丝藻(H.dissecrum)纤细链丝藻(H.subtile)溪生链丝藻(H.rivulare),中带鼓藻(Mesvtaenium eudlitherianum),集球藻(Palmellococcus miniatus),袋形藻(Physolinum monile),针丝藻(Raphidonema navile),孤枝根枝藻霍氏变种(Rhizoclonium heiroglyphicym var.husfordii),孤枝根枝藻长节变种(R.hieroglyphcum var.Longiarticylata),裂丝藻(Stichococcus fragilis),环轮桔色藻(Trentepohlia anmulata),和葫芦桔色藻(T.lagernifera)。

In the purpose of providing the floristic materials for the successive editions of the 'THE FLORA OF THE FRESHWATER ALGAE OF CHINA',the senior author tries to collect and study the aerial and subaerial algae, as well as those inhabited in other environments, firstly from the campus of Hubei University, Wuhan, Hubei Province. The names of 21 species ,including 2 varieties, belonging to 14 genera are given below. In addition , the ecological and taxonomical considerations are also stated as possible as the author can do for the further references. The names of the algae concerned are: (1)Chlorococcum humicola, (2)Palmellococcus miniatus, (3) Chlorella ellipsoidea, (r)Ch. vulgaris, (5) Ankistrodesmus obtusum , (6) Hormidium dissection, (7)H. flac-cidum, (8)H. rivulare, (9)H. subtile, (10)Stichococcus fragilis, (11)Raphidonema nivale, (12)Apatococcus lo-batus ,(13) Trentepohlia annulata, (14) T. lagenifera, (15) Physolinum monile,(16) Rhizoclonium heiroglyphicum var. hosfordii, (17)R. heiroglyphicum var longiarticulatum, (18)Cylindrocystis brebissonii, (19)Mesqtanium endlicherianum,(20)Cosmarium laeve, and (21) C. obtusatum. Among the above 21 taxa, 11 species including the 2 varieties are the new records in china.
