Fungi Found on Orchid Leaves 



The following are fungi found by Hennings* on 

 dead orchid leaves : 



Physalospora orcliidearum Henn. This fungus is 

 found on dead stems of orchids of Tainise stellatse 

 and Laelia schilleriana. It is probable that the fun- 

 gus Fhysalospora herbarum (Pers.) Rab. found on 

 dead stems of Phajuswallichii is the same as P. 

 orcliidearum. 



Pleospora orchidearum Henn. This fungus is 

 found on dried-up stems of Phajuswallichii. 



Nectria {Dialonectrid) bolbophyli Henn. This 

 fungus is found on dead pseudo-bulbs of orchids of 

 Bolbophyllum lobbii. 



Nectria behnickiana Henn. This was found on 

 orchids imported from Brazil. 



Macrophama oncidii Henn. This fungus was 

 found on dead leaves of Oncidium pulvinatum. 



Macrophoma cattleyicola Henn. This fungus was 

 found on pseudo-bulbs of Cattleya labiata. 



Diplodia sobralice (Henn.) Taub.t Found on 

 dead leaves of Sobralia scssilis. 



Other Fungi Found on Orchids 



Stibella bulbicola Henn. is found on pseudo-bulbs 

 of Gomeza plantifolia, Stanhopea spec, Sarcanthus 

 pugioniformis, Epidendrum spec, and on Oncidium 

 pulvinatum.
