REVISIONS OF CEYLON FUNGI. 289 



hyaline, elliptic conidia, 5-6 X 3 (jl. The conidia are borne 



singly on the tips of the hyphai, not in chains. 



According to von Hohnel's account, Ustulina zonata differs 



completely from Ustulina vulgar is in its conidial stage. This 



is completely at variance with the experience of numerous 



cultivations of the Ceylon species, and if it is correct the latter 



is evidently not Ustulina zonata. But in view of the close 



resemblance of the Ceylon and Javan forms in other respects, 



it would seem more probable that the Gh-aphium is a parasite 



on the Ustulina, not a conidial stage of it. It may be pointed 



out that one would not expect to obtain the conidial and 



ascigerous stages of Ustulina on the same stroma at the same 



time.

Sphceria (CcBspitosce) lignyodes B. & Br., Journ. Linn. Soc, 

 XIV., p. 128. 



Perithecia superficial, scattered, or crowded in large groups, 

 covering several centimetres , on a thin stroma, clavate, up to 2 

 mm. high and 0*8 mm. diameter, fleshy, black, minutely 

 roughened, ostiolum not elevated. The lower half of the 

 " perithecium " forms a solid " parenchymatous " stalk ; the 

 cavity in the upper half is oval, about 0*8 x 0*5 mm., with a 

 wall about 0-1 mm. thick. Asci clavate, apex truncate, 

 pedicel long and tapering, sporiferous part 80-90 X 12-16 ^, 

 eight-spored : spores at first obliquely uniseriate, then 

 biseriate above, uniseriate below. Paraphyses numerous, 

 filiform. Spores varying from narrow-oval to subcymbiform 

 and slightly curved, ends rounded, at first greenish hyaline 

 and three -guttulate, finally fuscous and one- to three-septate. 



The immature, or just mature, perithecia become cup- 

 shaped when drying ; the perithecia which have extruded 

 their spores do not collapse.

100. — Fracchiaea brevibarbata (B. & C.) Sacc. 



In Grevillea, XX., p. 113, Cooke states that Fracchicea brevi- 

 barbata (B. & C.) Sacc. " was found on Acer rubrum, in South 

 Carolina, on bark in CJeylon, and Rhus copallina, Santee 

 Canal, S. Carolina.' In response to my inquiry the Kew
