Deskripsi

Correct identity of a   fungus   absolutely   free   from   ambiguities   is   vital   for   i ts   employment   in   applied   disci- pline.  The  weeds  and  forest  plants  serve  as   reservoirs  of   leaf   spot   pathogens  which   on  getting  opportunity may  spread  to  agricultural   and  horticulture  plants.  Keeping  this  view  in  mind  the  authors  during  January  9- 12,  2088  while  in   Mahabaleshwar,  surveyed  the  lush   green  vegetation   for  folicolous  fungi  on   Jan  10,   2008. The authors collected eleven host  plants  being parasitized  with  none  fungi.  out  of  these  two hosts  Syzygium  sp. Linn.  (Myrtacear;  HClo-  48269)  and  Flacourtia  indica  Merrill  (Flacourtiaceae;  HClO-   48270)  were   found infected with novel species of Meliola syzygineaSingh and Mall sp. no. and M. flacourticola Sing and Mall sp. nov. respectively. The fungal  diversity  of  Phyllosphere  mycoflora  of  the  above  said  two  hosts  were  worked  out following standard  methods.  On  Syzygium sp.  Linn.,  Meliola syzginea Singh  and  Mall  sp.  no.  only was  represent- ing frequency class D where as Aspergillus niger Van Tiegh, A. flavus L., Curvularia sp. (Waker) Boedifin was representing class  C; A.  Terreus Thom,  Scoratia sp.,  Mucor sp.  class  B;  Fusarium sp.  Sheldon and Penicillum  sp. class A. No fungus was found representing  frequency class  E. On  Flacourtia  indica Merrill,  Aspergillus niger Van Tiegh only was found representing frequency class E where as Meliola flacourticola Singh and Mall  sp. nov.  and ustus Thom and Church represented class D; Trichoderma verdi  Pers.  ex Fr.,  Fusarium  sp. Sheldon.  class  C; Rhizopus sp. Ehrenb ex Corda,  Scoratia sp. class B and Trichoderma sp.,  Penicillium globarcum class A.
