mm. wide. They are rather more pvJvinate than is usual, and 

 up to 0"45 rani, thick. Some are flattened-iiulvinate, with 

 scattered pycnidia, others are almost horseshoe-shaped, with 

 circularly-arranged pycnidia. The paraphyses attain a Isngth of 

 120 [I, and some show light and dark lengths. Tiie pycnospores 

 are narrow -lanceolate, 10-13 X 2-2 • 5 ^. The specimen is marked 

 *' 589, on leaves of Ficus asp?ra, Brisbane." A specimen in Herb. 

 British Museum, marked SelenosporO. hypocreoidea Cke. & Mass., 

 from Linstead, Jamaica, Mrs. E. M. Swainson, is Aschersonia 

 basicysUs. 



The type specimen of Aschersonia Zenkeri, on an undetermined 

 leaf from Bipindi, Cameroons, Zenker No. 43, is in Herb. Berlin; 

 as some of the stromata bear developing perithecia at the margin 

 it is evidently the Aschersonia stage of a Hypocrella approaching 

 H. Bacihorskii ; the paraphyses show well marked light and dark 

 lengths. Aschersonia paraphysata forma Balanseana Sacc, ex 

 Herb. Saccardo, on leaves of Boehmeria, Tonkin, is A. hypocre- 

 oidea. Parkin's specimen A5, p. 37, on Aleyrodes sp. on leaves of 

 Flemingia strohilifera, Peradeniya, is this species ; the light and 

 dark lengths are well-marked in some paraiJhyses, but not in 

 others inthe same pycnidium ; this collection contains, in addition 

 to the usual thin forms, minute pulvinate specimens with a few 

 central pycnidia. In another Ceylon gathering on Aleyrodes sp. 

 on Argyrcia populijolia, the stroma is sometimes a mere film, 

 with scattered superficial spore masses. Specimens ex Herb. 

 Raciborski, on Unona sp., Depok, Java, have also been examined. 

 The specimens issued in Sydow, Fungi exotici exsiccati. No. 192, 

 as Aschersonia novo-guineensis, onlesivesoi Ficus ulmijolia, Philip- 

 pines, are A. hypocreoidea. 



The pycnidial stage of Hypocrella Raciborskii differs in its 

 pulvinate stroma, shorter paraphyses, and red-brown spore 

 masses. 



. Distribution. — Ceylon, in Herb. Peradeniya. Tonkin, in 

 Herb. Saccardo. Java, in Herb. Raciborski. West Africa, 

 in Herb. Berlin. Philippines, in Sydow, Fungi exotici exsiccati, 

 No. 192. Formosa, in Herb. Sapporo {sub A. Aleyrodis). 

 Australia, in Herb. Kew {Fusarium hypocreoideum). 



Figures. — Plate 3, fig. 41, Ceylon specimen, x 8 ; Plate 5, 

 fig. 45, section, x 10. The processes at the margin of the stroma 

 in fig. 41 are due to the growth of the stroma over the hairs of 

 the leaf, and are not a normal feature of the fungus. 



Aschersonia Goldiana Scacc. & Ellis, Sylloge Fungorum, 

 XIV., p. 990 (1899). — Stromata up to 6 mm. diameter, oval or 

 circular, flattened-pulvinate, up to 1*5 mm. thick, minutely 

 tomentose, white or pale yellow, sometimes surrounded by 

 a membranous hypothallus. Pycnidial orifices scattered or 

 circularly arranged, ultimately hidden by the orange-yellow
