Nectria bieolor B. & Br. 



This was described by Berkeley and Broome in Fungi of 

 Ceylon, No. 1023, as " Csespitosa, pallide coccinea vel ochracea, 

 isevis ; sjjoridiis minoribus oblongo-ellipiticis uniseptatis. 

 Sporidia 8*75 ;x long, 2'5 ^j, broad." The type is Thwa^fes 

 647 in part. The co-type in Herb. Peradeniya is marked 

 647 (29 part), and is on the same sheet as N. Bambusae and 

 N. stenos2iora. 



The perithecia are conoid, 0*2 mm. diameter, apex acute, 

 minutely pruinose ; when immature they are reddish-brown 

 and somewhat translucent, but when mature they are pale 

 ochraceous and opaque. In the type they are seated in groups 

 on a horny-looking stroma, which sometimes extends beyond 

 them. The asci are clavate, eight-spored, with spores biseriate 

 above, about 40 x 8 ^jl. The spores are narrow-oval to 

 subfusoid, one -septate, not constricted, minutely rough, ends 

 rounded, sometimes acuminate, usually 9-12 X 3-4 ^, 

 sometimes 10-14 x 4-5 [k. 



In a recent gathering, which developed on the cut cross 

 section of a Hevea log, the perithecia are scattered or crowded, 

 without any evident stroma (3067 in Herb. Peradeniya). 



Nectria rigidiuscula B. & Br. 



This was described by Berkeley and Broome in Fungi of 

 Ceylon, No. 1024, as " Csespitosa ; peritheciis ovatis palUde 

 coccineis vix coUabentibus ; sporidiis submetulseformibus 

 quadrinucleatisj demum 3-septatis. Allied to N. ochraceo- 

 pallida, but of a very different colour and appearance. 

 Sporidia 25 [k long." The type specimen was Thwaites 173 c. 

 In Saccardo this species was listed as Calonedria. The type 

 specimen is not in Herb. Kew, but in Herb. British Museum, 

 from Broome's herbarium. Examination shows that it is 

 identical with the later Calonectria sulcata Starb. and Calo- 

 nedria Melix Zimm. von Hohnel has recorded Ceylon speci- 

 mens from the type of Nectria stenospora B. & Br. 



This is one of the commonest Ceylon Nectria s, and occurs in 

 abundance on dead cacao, Hevea, &c., with Nectria haemalo- 

 cocca. The perithecia are scattered or crowded, amber to
