258 PETCH : 



A. flavocitrina. The spores of A. aleyrodis also average a little 

 smaller than those of A. flavocitrina. Measurements of Florida 

 specimens show that the spores of A. aleyrodis are about 9-14 

 X 2-3 jjt, while those of A. flavocitrina measure about 12-16 

 X 2-3 [X." The paraphyses of A. Goldiana are slightly longer, 

 and the stromata are thinner and do not exhibit the oblique 

 ostiola of A. aleyrodis. 



In Herb. British Museum there is a specimen from Venezviela : 

 "Plantes du Haut-Orenoque, Recueillies en 1887 par A. Gaillard. 

 No. 230 de la collection. Fusarium salmonicolor B. & C, sur 

 feuilles de Psidium, village d'Atures, 9. Aout "; this is Aschersonia 

 Goldiana, approaching in form Ascnersonia hypocreoidea. 



Distribution. — Florida, in Herb. Peradenij^a. Brazil, in Herb. 

 British Museum and Herb. Berlin {A. paraensis). Trinidad, in 

 Herb. Thaxter. Porto Rico, in Herb. Thaxter. Venezuela, in 

 Herb. British Museum (Gaillard, 230, sub Fusarium salmonicolor).

Aschersonia australiensis P.Henn., Hedwigia(1903),p,87.— 

 Stromata circular or oval, up to 2 mm. diameter, flattened- 

 pulvinate, up to 1 mm. thick, surrounded by a broad mem- 

 branous hypothallus, waxy and subtranslacent ; orange- 

 yellow or grayisli-yellow. Pycnidia scattered or arranged 

 circularly ; ostiola yellow ; i^ycnidia ovoid, or more or less 

 flask-shaped ; pycnospores narrow-oval or fusoid, ends 

 pointed but not produced, 5-10 X 1-1 "5 (x ; paraphyses up 

 to 70 \K long. 



The type specimen, from Queensland, Pritzel, 79, in Herb. 

 Berlin, is on an Aleyrodcs on Callistemon lanceolatus. In the 

 same cover is a gathering on Icerba brexoides, Diels, 6,444, which 

 is Hypocrella duplex. The type contains pulvinate, subtrans- 

 lucent stromata, sometimes depressed in the centre and displaying 

 the scale insect ; its spores are 5-8 x 1-1 • 5 ^. It resembles 

 pulvinate forms of A. placenta, some of which, e.g., those named 

 A. javanica, become subtranslucent, but differs in its smaller 

 spores. But the available material is scanty. In Herb. Kew, 

 sub A. oxyspora, there is a Queensland gathering on Cinnamomum 

 Olivieri which is, in part, this species ; some of these stromata 

 are more opaque ; the spores measure 5-10 x l-l'Sjjt. 



Distribution. — Queensland, in Herb. Kew and Herb. Berlin.
