MYCETOZOA OF CEYLON. 369 



the Ceylon and Australian gatherings. P. depressa is very 

 common in C/eylon. A gathering from Badurehya consists 

 partly of flattened, clustered, polygonal sporangia, as in typical 

 P. depressa, and partly of more globose, scattered sporangia, 

 as in P. populina ; the spores are 9 to 10 yt* in diameter. In a 

 collection from Henaratgoda the capillitiuni forms a loose 

 net, with free ends about 40 a* long, swollen at the extremities. 

 In several gatherings the lids of the sporangia are pale brown 

 almost without any granular deposits, but containing scattered 

 or crowded spherical yellow granules ; and in one from 

 Hakgala, which consists chiefly of purple-brown sporangia, 

 a few sporangia have membranous, iridescent, golden lids 

 the outer layer being absent. 



Peradeniya, Badureliya, Hakgala, Pattipola, Badulla, 

 Ukuwela, &c. 



Perichgena populina, Fries. 



Rare. A small gathering from Peradeniya is typical, except 

 that the spores are rather larger than usual, 13 to 16 /^ diameter. 

 In another gathering the sporangium wall is apparently 

 single, and the hd is covered by a gray cap of acicular crystals ; 

 the spores are smaU, 11 to 13 ^t in diameter, minutely wai'ted ; 

 the capillitium threads are 2 to 3 /' in diameter, somewhat 

 nodulose. 



Peradeniya. 



Perichaena microspora, Penzig and Lister. 



Rare ; only foimd once. Plasmodiocarj)s elongated, some- 

 times sinuous, r25 to 4*25 mm. long, 0*25 mm. diameter, 

 smooth, pinkish ochraceous ; wall single, membranous, or 

 thickened with deposits of granular matter towards the base, 

 minutely and closely papillose ; capillitium and spores pinkish 

 j'ellow in mass, almost colourless when mounted ; capillitium 

 of branching tlireads with frequent irregular expansions at the 

 axils, minutely spinulose everywhere, constricted at short 

 intervals so as to appear beaded, with numerous attachments 

 to the sporangium wall ; spores almost colourless, minutely 

 spinulose, 6' to 8 ft diameter.
