subglobose, at first thickened at apex, 4-8-spored, aparaphysate, 

 22-35 X 20-28/i. Sporidia conglobate, ellipsoid or subclavate, 

 straight or slightly curved, obtuse at both ends, hyaline or pale 

 yellowish, transversely 3-septate, more or less constricted at septa, 

 imperfectly muriform, 10-18 x i-6fx.

 1902 (Hobinson) — Near Mt. Falkiner, Tasm.; September, 1896

 Nees; July, 1901 (Pritzel). 



Dr. Hennings kindly forwarded a portion of the original 

 material on which the species was founded, and there is no doubt 

 of the identity of the Victorian and Tasmanian specimens. In 

 these the stromata occur on the young branches, the leaves and 

 the flower-stalks, and in the West Australian specimens they 

 occurred on the calyx-leaves as well. The stromata have their 

 base narrowed and inserted in the matrix, and although the 

 branches are not deformed still it is a very injurious parasite. 



The genus Myriangium^ Mont. & Berk., was formerly classed 

 among the lichens, but the absence of spermogonia and gonidia 

 exclude it. In Hooker's London Journal of Botany (Vol, iv., 

 p. 73, 1845), Berkeley records M. duricni from near Swan River, 

 "West Australia, but it was omitted from Cooke's ' Handbook of 

 Australian Fungi,' on account of its lichenoid nature. 



77. Phyllosticta marrubii, n.sp. 



Perithecia minute, black, punctiform, erumpent, prominent, 

 scattered, depressed-globose, golden to olivaceous by transmitted 

 light, membranaceous, of parenchymatous texture, with round 

 apical pore, 120-130/Lt diam., on both surfaces of pale brown 

 irregular spots, but mostly on upper. Sporules hyaline, oval, 

 5|-6 X 2J-3, occasionally reaching a length of 8/x.

At first the irregular pale brown spots are isolated, but ulti- 

 mately they coalesce and form large withered patches, often 

 towards the tip of the leaf. The spots usually occur on leaves
