MYCETOZOA OF CEYLON. 327 



thinner, more flexuose branches, the whole lying horizontally 

 and interlacing. Fresh specimens of C. arbuscula have been 

 collected at Peradeniya ; the sporophores in these are 5-8 

 mm. high, and up to 1 mm. in diameter at the base ; the stalk 

 is transparent and rigid when fresh, but shrinks to a thin 

 wliite thread in drying ; some sporophores are 5 mm. in 

 diameter at the top ; the bases are rather widely separated, 

 but, owing to the repeated branching, the outer branches of 

 adjacent sporophores are in contact, and the whole group 

 forms a fleecy, white sheet, completely covering rotten wood, 

 or bamboo culms, for a length and breadth of several feet : 

 the spores measure 10-12 x 8 yt^. This is the common form 

 of Ceratiomyxa at Peradeniya (1,500 feet); at Hakgala (5.600 

 feet) genuina only occurs, with simple or sHghtly branched 

 sporophores ; while a gathering from Talawakele (4,000 feet) 

 includes both forms together.

The specimen in Herb. Peradeniya (Thwaites ' 1046) 

 consists of winding plasmodiocai'ps , 2 to 4 mm. long and • 3 to 

 •5 mm. broad, or subglobose sporangia 5 to 1 mm. diameter, 

 in one part crowded into a convoluted mass measuring 6x4 

 mm. : the spores are in clusters of 3 to 10. Four recent 

 gatherings have been made, all at Peradeniya, on sticks, and 

 on the fallen spathe of a coconut. They consist of small, 

 subglobose sporangia, and elongated, winding, and netted
