378 AUSTRALIAN FUNGI, 



14. PflYLLOSTICTA GROSSULARIiE, SaCC. 



Armadale, Vic; on Gooseberry leaves; Jan., 1899. 

 Towards the margin of the leaves large areas become blotched 

 by the spots running together, and the leaves soon fall. 



15. Phyllosticta myrticola, Speg. 



Orbost, Vic. (Pescott); on living leaves of Eugenia smithii, 

 Poir.; July, 1900. 



This species has only hitherto been recorded on the living leaves 

 of a species of Eugenia in Brazil, and is new to Australia. 



16. Pleospora asclepiadearum, n.sp. 



Hyphfe adjoining perithecia sooty-brown, septate, branched, 

 twisting and anastomosing, up to 7-9 fx broad. Perithecia some- 

 what gregarious, at first covered by epidermis, then partially 

 naked, minute, black, punctiform, globose, ostiolum minute, 

 190-225 fi diam. Asci cylindrical-oblong, rounded at apex, 

 tapering into a slightly dilated knob at point of attachment, about 

 100 X 17-19 /x: paraphyses hyaline, about length of asci, slightly 

 swollen at apex (H /x broad), stained pale red by potassium 

 iodide-iodine. Sporidia distichous usually at base and monosti- 

 chous at apex, dark olive-green, ellipsoid, 5-septate, constricted 

 at septa, generally with four longitudinal septa, and occasionally 

 slightly muriform, 28-30 x 10-12 ^. 



South Australia (Molineux); on leaves of Hoya carnosa, R.Br.; 

 July, 1898. 



This disease has a very characteristic appearance. The upper 

 surface of the leaves has a large milk-white blotch, sometimes 

 occupying fully one-half the entire surface. 



F. diiylosjwra, Ell. & Ev., found on dead stems of Asclejnas 

 incarnata, L., in America, has much broader asci, and the straw- 

 coloured to brown sporidia may be 7-septate. 



The Phyllosticta asclepiadearum^ West., is probably an early 

 stage of this species, and, therefore, I have given it the same 

 specific name.
