| Holotype of |  Opegrapha luzonensis Sérusiaux | 
| Verified by | E. Serusiaux (LG) | 
| Determination Remarks | [Serusiaux put a label with the information 'Holotype' on the specimen and cites FH for having the holotype; However, in his publication he cites Elmer 19963 as being the holotype and this specimen has the number 16963! I assume it is a misprint in the publication] M. Schmull, March 2009 |
