HORNE : A NEW SPECIES OF LeMBOSIA 



thecia irregularly scattered in the spots, straight or variously- 

 curved, or forked, about 1 60// broad by 350// to I mm. long or 

 more, continuous below with the mycelium, usually a little 

 broader than high, black. Asci broadly clavate to elongated 



ovate, narrowed and often curved at base, 

 at maturity thickly coated, 20-40 by 8-1 5 /i, 

 the apex becoming produced into a sac-like 

 extension 10 to 15/i long which is col- 

 lapsed and brown about the ruptured apex 

 after the escape of the spores. Paraphyses 

 abundant, somewhat irregular, the tips a 

 little broader and clavate, separating with 

 difficulty, 2-3 fJt broad, not exceeding the 

 expanded tips of the asci. Sporidia most 

 commonly 6 in an ascus (probably 8 in 

 uninjured asci), biseriate or irregularly

brown and nearly black with one or two 

 small oil-drops in each cell, and the darker spores mostly a little 

 smaller, 10-16 by 4-5 a. 



On green stems of Vam7/a planifoUa Andr., the cells of the host 

 below the mycelium becoming gradually filled with brown gran- 

 ular material, and groups of brown vesicles appearing irregularly

 into the intercellular spaces for a short distance. The significance 

 of these structures was not made out. The superficial mycelium 

 was not seen to penetrate below the cuticle in a larcre number of
