The synonymy of the species is as follows : — 

 Dothidasteroma maculosum (B. & Br.) v, H., Fragm., X., 

 No. 498 ; Rhytisma maculosum B. & Br., Jour. Linn. Soc, 

 XIV., p. 130 ; Rhytisma Pterygoid B. & Br., ibid., p. 131 ; 

 Dothidasteroma Pterygotse (B. & Br.) v. H., Fragm., IX., 

 No. 443 ; Marchalia maculosa (B. & Br.) Sace., Syll. Fung., 

 VIII., p. 737 ; Marchalia Pterygotse (B. & Br.) Sacc, ibid. 



The specimen on Cansjera Rheedii is not Dothidasteroma. 

 According to von Hohnel, it bears a Meliola, closely allied to 

 Meliola amphitricha (Fr.), and two species of Asterina, one 

 with smooth spores and the other with spinulose spores. The 

 latter has been described by him as Asterina echinospora, 

 Fragm., X., No. 508. 



222.— Rhytisma fllicinum B. & Br. 



Berkeley and Broome described this from a specimen on 

 Alsophila gigantea (= Alsophila glabra Hk.), Thwaites 453, 

 collected in May, 1856. It was included under Marchalia by 

 Saccardo. After examination of the type in Herb. Kew, von 

 Hohnel transferred it to Hysterostomella, as H.fiUcina (Fragm., 

 No. 447). Theissen and Sydow (loc. cit., p. 220) have instituted 

 for it a new genus Monorhizina. It now stands as — 



Monorhizina fiUcina (B. & Br.) Theiss. & Syd. ; Rhytisma 

 filicinum B. & Br., Jour. Linn. Soc, XIV., p. 130 ; Marchalia 

 filicina (B. & Br.) Sacc, Syll. Fung., VIII., p. 738 ; Hysterosto- 

 mella filicina (B. & Br.) V. H., Fragm., IX., No. 447. 



223. — Rhytisma Pongamise B. & Br. 



Described by Berkeley and Broome from Thwaites 492, on 

 Pongamia glabra, and included in Saccardo under Cryptomyces. 

 It was re-described as Phyllachora in Ann. Perad., V., p. 291, 

 and now stands as — 



Phyllachora Pongamise (B. & Br.) Fetch ; Rhytisma Ponga- 

 mise B. & Br., Jour. Linn. Soc, XIV., p. 130 ; Cryptomyces 

 Pongamise (B. & Br.) Sacc, Syll. Fung., VIII., p. 708. 



224. — Rhytisma placenta B. & Br. 



This was described by Berkeley and Broome from Thwaites 

 409, on leaves of Symplocos spicata, and Thwaites 420, on 

 Pavetta indica. They stated that it was possible that the two
