36 PBTCH ; 



mounted show a netted structure, which merges at the margin 

 into a thin sheet of hyaline hyphse running over the leaf. The 

 hyphse are about 4 [i. diameter, sometimes constricted at the 

 septa, and^ do not bear hyphopodia. Older examples are 

 elevated in the centre, and show a developing perithecium 

 about 0'3 mm. diameter, with a parenchymatous "wall, 

 surrounded by a dense weft of hyphee, which merges into the 

 hyahne hyphse as before. The ostiolum is about 30 ^ diameter. 

 Unfortunately all the specimens in the type appear to be 

 immature. 



270.— Phoma Lobelise B. & Br. 



This species was described by Berkeley and Broome in Fungi 

 of Ceylon, No. 802, from Thwaites 301, on Lobelia nicotianee- 

 folia. Their description is " PustuJis epidermide alba tectis, 

 demum emersis ; sporis ellipticis. Spores 3 '75 jji, long." 

 The fungus grew on the dead flowering stalks of the Lobelia. 



The pycnidia are lenticular, immersed in the cortex ; they 

 are oval in plan, up to 0*5 mm. long and 0*3 mm. diameter, 

 and 0-15 to 0-2 mm, high. They remain covered by the 

 whitened epidermis, as a rule. The ostiolum is broadly 

 conical, or subcylindric, short, and protrudes through the 

 epidermis. The wall of the pycnidium is stout, black, and 

 parenchymatous. The spores are oblong with rounded ends, 

 5-9 X 1 • 5-2 \x, and show a blue band across the middle on 

 staining with Cotton Blue ; with these are flexuose or uncinate 

 spores, tapering towards the ends, 14-24 X 1 [i.. In modern 

 classification this is a Phomopsis, and will stand as Phomopsis 

 Lobelise (B. & Br.). 



The co-type in Herb. Peradeniya contains principally an 

 entirely different fungus. This forms stromata between the 

 wood and the cortex, usually superficial on the wood, but 

 sometimes sHghtly immersed in it, becoming free when the 

 outer tissues weather off. They are small, black, irregularly 

 pulvinate, scattered, either circular, 0*5 mm. diameter, or 

 oval, 0*6 X 0*4 mm., often ridged, with broadly conical, 

 obtuse ostiola, which penetrate the epidermis but scarcely 

 project. Internally they are dark brown and parenchy- 

 matous, and contain* a few, distant, globose perithecial
