former measured 8-13 X 4-5 |ji,, while the latter, from the 

 same perithecium, were 11-13 X 2-2*5 \k. A fmrther exami- 

 nation, of these specimens, and a comparison with a number 

 of others, in connection with the present revision, has con- 

 vinced me that these are only nearly bald specimens of Nectria 

 flavolanata. The tjrpical hairs can be found in many cases 

 near the base of the perithecia. 



It would seem probable, in view of the foregoing, that 

 Berkeley and Broome examined a nearly smooth specimen of 

 Nectria flavolanata for their spore measurement of Nectria 

 stenospora. These are the only spores I have seen in a Ceylon 

 Nectria Avhich would warrant the name stenospora. 



There is, however, another species ex Thwaites 647, which 

 has claims to be considered Nectria stenospora. It occurs 

 in the cover of Nectria bicolor in Herb. Kew, and again, 

 evidently part of the same collection, in the cover of Nectria 

 sanguinea. The latter specimen is marked Ceylon, but is not 

 numbered. In Herb. Peradeniya it is included in the sheet, 

 Thwaites 647. 



The perithecia of this last species may occur singly, in 

 which case they appear superficial, but they are usually 

 densely congregated on an erumpent stroma, in pulvinate 

 masses up to 5 mm. diameter. The perithecia are at first 

 bright red, but when old they become dark red. They are 

 subtranslucent, and smooth, without warts or hairs. The 

 stroma is parenchymatous, with small thick-walled cells, or 

 somewhat sclerotioid. It is paler than the perithecia, being 

 orange red above, and yeUow internally, sometimes almost 

 hyaline at the base. When some of the perithecia have 

 been broken away, the specimen appears bicolored, the 

 perithecia showing dark red, and the surface of the stroma 

 orange red. 



When young, the perithecia collapse laterally. The older 

 specimens apparently do not collapse. In most of the Kew 

 specimens the perithecia are collapsed laterally if perfect, but 

 many have been broken, and only the lower part is left as a 

 cup. In Herb. Peradeniya one part of the specimen shows fully 

 mature, unbroken perithecia . The immature perithecia appear 

 conoid ; the mature perithecia are ovoid or suburceolate,
