coloured, or sometimes ^vith a purple tinge intemally, with 

 yellowisli-green spores. It is evident therefore that all this 

 synon>iny is incorrect, and that while Spficeria lenta Tode 

 may perhaps be the same as Hypocrea Schweinitzii (Ft.) 

 E. & E., the latter is certainly not the same as the " Hypocrea 

 lenia Fr." of Berkeley and Broome. \Vhat the latter really 

 is has not been determined ; it appears to be undescribed. 

 But it seems scarceh' worth while to institute new species of 

 Hypocrea \\hile there exist so many doubtful descriptions of 

 tropical species Avith hyaline spores most probably based on 

 immature specimens. 



98. — Ustulina zonata Lev. 



This species was originally recorded from Java on a dead 

 palm stem. The specimens were apparently immature, since 

 no spore measurements have been made on the type specimen ; 

 and hence all recent determinations of the species are based 

 on macroscopic characters only. It was collected again in Java 

 by Penzig and still more recently by von Hohiiel. Von 

 Hohnel states that it has not been found elsewhere, but it has 

 for some years been well known as the cause of root disease of 

 several plants in Ceylon. Thwaites sent numerous specimens 

 to Herkelcy, who referred them all to Ustulina vulgaris Tul. 

 Whether it is really distinct from that species is a matter of 

 (l()ul)t : but there seems no doubt that the various recorded 

 collections of Ustulina vulgaris from South America are 

 the same as what is known in the East as Ustulina 

 zoiKtta. 



Ill (.V?ylon it attacks the roots of tea, Albizzia inoluccana, 

 Citrus sp . , Cassia nodosa , and Lafamsia Vandelliana . In the case 

 of tea, it (Iocs not attack the roots directly, but only through 

 the agency of a neighbouring tree stuni]), usually Grevillea. 

 iiTcvillm rohu^la is jilanted among tea as a wind-break or for 

 green manuring ; when these trees are cut down Ustulina 

 develops upon the stump and spreads along the roots to the 

 roots of the surrounding tea bushes. On the other plants 

 named, howcvci-. IIk- attack is direct. Ustulina zonata is 

 commonly found on dead coconut palms, but only, so far as 

 baa been ascertained, as a saprophyte.
