CKYLON Pimoi. ^ 63 



one-celled, about 7x5 ^,. The perithecia have the usual 

 stellate appearance of Asterina : they are minute, crowded, 

 flattened, about 80 ^ in diameter, and rupture at the apex. The 

 spores are elhptic or pear-shaped, 19-28 x 12-14 /i, blackish 

 brown with a pale zone in the middle. I have examined a large 

 quantity of material, but have not been able to find any septate 

 spores, nor any asci : the immature spores are borne singly 

 on short basidia. 



It appears therefore that the Ceylon fungus is a Capnodias- 

 trum. Cooke's description of the spore of his Asterina agrees 

 with the usual spore of Capnodiastmm except that he states 

 that it is finally one-septate. The Ceylon species will be 

 known as Capnodiastrum congesium, as it is most probably 

 the same fungus as that examined by Cooke. An exact state- 

 ment on this point must depend on an examination of Cooke's 

 type specimen, which is probably in England.

" 798. Aschersonia mellea, B. & Br. Pulvinata, mellea, 

 glabra, cellulis demersis, sporis sub-ellipticis nucleatis (No. 730). 

 On dead bark. South of the Island, July, 1868. A line or 

 more across." (Journ. Linn. Soc. XIV., p. 89.) 



Thwaites' specimen No. 730, bearing the inscription 

 " South of the Island. July, 1868," consists of two pieces of 

 bark bearing forty-six examples of this supposed Aschersonia, 

 and two detached specimens. They are yellow brown, 

 pulvinate, glabrous, faintly ridged, irregular^ oval. The 

 two detached specimens are inverted, and bear gills. Those 

 on the bark are attached only at one edge, and sections show 

 that they are all a small sessile, excentric agaric {Pleurotus ?) 

 in various stages of development. '^The largest specimen is 

 5x3 mm.
