specimens to support that view, and it would therefore appear 

 that their description, ' Turning the whole contents of the 

 seed into a black powder,' was a mistake. According to 

 the specimens . the species must be known as Cerehella inquinans 

 (B. &Br.). 



Thecaphora Berkeieyana Fischer. 



This was recorded by Berkeley and Broome as Polycyslis 

 mncularis B. & Br. ' Soris brevibus spicicolis ; sporis globosis 

 paucicellulosis. On Andropogou perforatum , Damboul, March, 

 1868." 



Fischer, in "Apercu systematique des Ustilaginees," p. 38, 

 refers to it as Urocystis macnlaris (B. & Br.) Fischer, and 

 mis-translates '' Soris brevibus spicicolis "' as " en sores courts 

 et pen pointus."' In " Les Ustilaginees et leurs plantes 

 nourricieres " he names it Thecaphora Berkeleyarw . and giv-es 

 a I'e -description based upon a specimen sent by Berkeley. 

 Finally, in Grevillea, XVII., p. 19, Cooke states that it is 

 identical with Cerebdla andropogonis Ces. 



It is evident that the name Andropogon perforatiis is an 

 (?rror, smce that grass does not grow in Ceylon. Th(* name 

 has been queried on the specimen in Herb. Kew, and some one 

 has added Andropogon favcolaliis Delile. which again is not a 

 Ceylon sj)ecies. An examination of the Andrnpogov shows 

 that it is Andropogmi pcrluMis Willd., '' pirforntvs" being 

 apparently a sUp on Thwaites' part, since the name is in his 

 handwriting. 



The type specimen in lierb. Kew contains Andropogon 

 prriustLs Willd. and ? Pasjxiluvi sp., while the packet of 

 duplicates contains, in addition, ? Eragrontw sp. The fungus 

 on AndrnptHjon pcrluHus is immature ; it is prol)ably immature 

 Cerebdla andropogonis , but it has not reached the stage at 

 which the brain-like structure of the latter is evident ; it 

 forms very minute firm stromata on the cxtenor of the fruits, 

 with spores uj) to 10[x diameter. The ? Pa,spalum bears an 

 undoubted ('rrebrlla. which is probably Cercbelfa inqvinan^'< 

 ( H. & Br.). Very little is left of the specimen on / Kragrodis, 

 and what there is might be immature Cerehella or Balansin, 

 &c. ; I was not able to Hnd any spores.
