Fungi Found on Orchid Leaves 



The following are fungi found by Hennings* on 

 dead orchid leaves : 



Physalospora orchidearum Henn. This fungus is 

 found on dead stems of orchids of Tainiae stellatje 

 and Laelia schilleriana. It is probable that the fun- 

 gus Physalospora herbarum (Pers.) Rab. found on 

 dead stems of Fhajuswallichii is the same as P. 

 orchidearum. 



Pleospora orchidearum Henn. This fungus is 

 found on dried-up stems of Fhajuswallichii. 



Nectria (Dialonectrid) bolbophyli Henn. This 

 fungus is found on dead pseudo-bulbs of orchids of 

 Bolbophyllum lobbii. 



Nectria hehnickiana Heim. This was found on 

 orchids imported from Brazil. 



Macrophama oncidii Henn. This fungus was 

 found on dead leaves of Oncidium pulvinatum. 



Macrophoma cattleyicola Herm. This fimgus was 

 found on pseudo-bulbs of Cattleya labiata. 



Diplodia sobralia (Henn.) Taub.t Found on 

 dead leaves of Sobralia sessilis. 



Other Fungi Found on Orchids 



Stibella bulbicola Henn. is found on pseudo-bulbs 

 of Gomeza plantifolia, Stanhopea spec, Sarcanthus
