MYCETOZOA OF CEYLON. 341

Didymium zeylanicum, Berk., Hooker's Journal of Botany, 

 Vol. 6 (1854), p. 230. Didymium zeylanicum, B. & Br.,

 and Broome, Fungi of Ceylon, No. 1193. 



The spores of this species vary much in size. Berkeley 

 and Broome's specimens, 754 and 1193, have pale spores, 9 

 to 10 fi diameter. In three recent Ceylon gatherings the 

 spoi'es are dark violet-brown, spinulose, and measure 11 /x, 

 11 to 12 A*, and 15 to 18 /* respectively, but there are no other 

 characters by whicli the last could be separated as a distinct 

 species. The plasmodium is grayish white, and has been 

 found on decaying Hirneola polytricha. 



On dead wood. Gangaruwa, Ukuwela, Ratnapura. 



Erionema aureum, Penzig. 



In a typical gathering of this species, from the under surface 

 of a dead Hevea log at Yatipauwa, the strands of cylindric 

 sporangia are up to 5 cm. long and 6 mm. broad, attached 

 to the substratum by a scanty white thread-like hypothallus ; 

 the sporangia are yellow or greenish- yellow ; spores 6 to 8 m 

 diameter, minutely spinulose ; capiUitium typical. Another 

 specimen, on a dead leaf, from Badureliya, consists of yellow, 

 heaped, convoluted sporangia, in a mass about 1-5 cm. 

 broad, instead of hair-like tresses ; the sporangia are irregularly 

 bolster- shaped and usually compressed laterally ; the sporan- . 

 gium wall is membranous with dense yellow lime deposits in 

 somewhat rounded lumps ; the capillitium is typical, a network 

 of rigid, hyaline or yellowish, didymium-like tlirea,ds, with a 

 few spindle-shaped thickenings and fusiform orange lime knots ; 

 the spores are 7 to 9 /i* in diameter, with a few largej spores 11 

 to 14 A*. 



BadureHya, Yatipauwa. 



Cienkowskia reticulata, Rost. . 



Plasmodium deep orange-red, on and in decaying palm 

 leaves. A plasmodium on the stalk of a decaying palm leaf kept 

 in a damp chamber in the laboratory remained on the upper 

 surface for four days, and then crawled underneath to form a 

 plasmodiocarp on the lower surface. Theplasmodiocarps were
