REVISIONS OF CEYLON FUNGI. 427 



straight or slightly curved, 72-110 x 11-13 /*. Paraphyses 

 linear, short, in a dense fringe, about 30 ^ long. 



Berkeley and Broome state that the spores are • 003 inches 

 long, i.e., 75 /^ long. In Saccardo, Sylloge Fungorum, they are 

 said to be 7 • 5 ft long. Tlie measurements given above were 

 obtained from extruded spores, aU from the same stroma. 

 Specimens recently collected agree with the type in Hei'b. 

 Peradeniya. It grows on dead stems of Amomum spp.

Berkeley and Broome's type of Hypoxylon ceramichroum in 

 Herb. Peradeniya contains twenty-one specimens, measuring 

 from 1"5 to 9 mm. in diameter. The larger are almost 

 spherical, the smaller about two-thirds of a sphere. The colour 

 is red-brown externally, with the exception of one example 

 which is somewhat clay coloured, becoming black. Internally 

 •the colour is pale yellow to brownish-red. They are attached 

 to the stem of a Smilax, but it is easy to see that the stem 

 was quite sound when collected and that the fungus could not 

 have developed at the expense of its tissues. The specimens 

 are superficial and easily detaclied, as stated by Berkeley and 

 Broome, and when detached they leave an oval scar, or 

 rather discolouration, on the stem. Examination of the base 

 of the specimens proves that they grew, not on the stem, but 

 on a scale insect, and there is sufficient left of the latter to 

 show that it is Lecanium nigrum. 



Berkeley and Broome cut sections of the largest specimen, 

 but unfortunately size is no criterion of development in Hypo- 

 crella ; the perithecia in that particular example are all 

 immature, and abnormally arranged somewhat regularly near 

 the periphery. Still, it is possible to find in them asci wilii 

 parallel spores. The smaller examples bear perithecia and 

 pycnidia at varying depths, and the asci contain large numbers 

 of smaU spores, identical with those described below. There is 

 no doubt that the fungus is a Hypocrella. I have had no 

 opportunity of consulting Cooke's later description in Grevillea.
