HYPOCRELLA AND ASCHERSONIA. 259 



or suberect, columnar processes, pale yellow, minutely 

 pruinose, total height about 0'7 mm., usually with a scarious 

 hypothallus ; processes cylindric, often laterally compressed, 

 up to 0* 5 mm. high, 0' 6 X 0* 4 mm, in cross section ; pycnidial 

 orifices at the apices of the processes, usually solitary, oval, 

 rarely two and circular , mass of pycnospores usually brownish- 

 yellow, sometimes red-brown ; pycnidia regular, shortly 

 cylindric, about 0*2 mm, broad and deep ; pycnospores fusoid, 

 ends pointed but not produced, 14-20 X 2-2*5 {x ;paraphyses 

 linear, up to 130 [x long. On an Aleyrodes on Ilex dahoon, 

 Florida. 



This species was included in a collection forwarded by Mr. 

 H. S. Fawcett. At first siglit, the stromata resemble small 

 specimens of Aschersonia turhinata, from which it especially 

 differs in the presence of paraphyses. It resembles the Ascher- 

 sonia stage of Hypocrella tuhulata, but has a different pycnidium 

 and longer pycnospores. From Aschersonia acutispora, from 

 Australia, it differs in the shape of the pycnospores. No 

 other species resembling this has been seen from the Western 

 Tropics. 



Aschersonia acutispora Fetch, n, sp, — Stromata yellowish, 



opaque, simple, cylindric, about 0'8 mm, high, 0'6 mm. 



diameter, with a broad scarious hypothallus, up to 1 mm, 



wide, or (?) botryose, with clustered processes up to 0*5 



mm, high and 0*3 mm, diameter; pycnidia (in the simple 



forms) single, central, flattened-globose, about 0*3 mm, 



high and 0*4 mm. diameter; pycnospores narrow-oval, 



tapering abruptly towards the ends, 10-14 x 2-2*5 [;,; 



paraphyses up to 180 [>. long. On an Aleyrodes on Cinrmmo- 



mum Olivieri, Queensland, in Herb, Kew, 



In the cover of Aschersonia oxyspora in Herb. Kew there is a 

 gathering from Queensland, which is in part Aschersonia australi- 

 ensis, and in part the present species, which differs from Ascher- 

 sonia australiensis in the shape of the stroma and the spores. 

 The fertile stromata are all simple, but botryose forms are also 

 present, which appear to be the same species. Unfortunately, 

 the botryose forms examined were immature. Aschersonia 

 duplex has a similar pycnidium, but its paraphyses are shorter, 

 and its spores a different shape. The spores of Aschersonia 

 acutispora resemble those of Aschersonia oxystoma, but the 

 latter does not possess paraphyses, and its pycnidia are different. 



The material is scanty, but it cannot be included in any other 

 known species.
