17. Ramularia hordei, n.sp. 



Forming whitish patches not very conspicuous on brownish 

 lenticular spots, which may run together and become dark brown. 

 Hyphse ramifying in leaf, septate, branched, and bearing at surface 

 the conidia. Conidia straight or fusoid, hyaline, acute or blunt 

 at ends, 1-septate when mature, not constricted at septum, 

 15-17x3^. 



New South Wales (Farrer); on leaves of Barley; Oct., 1900. 



There is only one species of Ramularia recorded on Graminese, 

 viz., R. graminiGola^ Peck, on living leaves of Poa serotiita, Ehrh., 

 but the conidia are 25-35 /x long, and spuriously 1-septate, whereas 

 in this species they are decidedly 1-septate. 



18. Ramularia PRiMULiE, Thuem. 



Armadale, Vic; on leaves of Primula sinensis^ Sabine; July, 

 1902. 



It forms large pallid areas, with more or less orbicular centres. 

 The spots on the Primrose leaves are very common in the winter 

 months, but the fructification of the fungus is rarely obtainable 

 except from perfectly fresh specimens. 



19. Septoria STBLLARiiE, Rob. & Desm. 



Armadale, near Melbourne, Vic. ; on languishing leaves of 

 Stellaria mediay Cyrill; July, 1900. 



The spots were distinct at first, and then became confluent. 



20. Valsa ambiens (Pers.), Fr. 



Perithecia usually 5-6 imbedded in stroma. Spermogonial 

 stage [Cytospora carphosperma) with sporules escaping in tendrils 

 of a whitish to yellowish colour.
