others opaque with a yellow edge ; the wliite stalks of the 

 normal specimens are brownish at the base. Another gather- 

 ing contains yellow-brown sporangia on stalks of the same 

 colour, orange-red (mature) sporangia on white stalks, and 

 yellow-brown sporangia on white stalks. From a large 

 gathering, chiefly of the normal form, sixty specimens were 

 picked out which had sulphur-yellow sporangia, white stalks, 

 and faintly yellow lime knots ; and in another set of the same 

 colour the lime knots varied white or yellow in the same 

 sporangium. A small gathering on a single dead leaf shows 

 minute yellow sporangia, 0-3 mm. diameter, sometimes with 

 orange blotches, scaly : stalks yellow-brown, fluted, sometimes 

 twisted, somewhat expanded upwards, 0*5 mm. high, 0* 1 mm. 

 diameter, not containing lime ; Ume knots generally j-ellowish, 

 but a few white. The spores are usually 8 to 9 /^ in diameter. 

 Plasmodium watery ochraceous yellow. 



Peradeniya, Talawakele, Gangaruwa, &c. Apparently not 

 at Hakgala (5,600 feet), 

 Physaruni tenerum, Rex. 



A gathering from a decaying stump at Peradeniya has pale 

 yellow stalks 1-5 ram. high, containing lime or refuse matter 

 in discontinuous lengths ; the sporangia are ■ 4 mm. diameter, 

 iridescent, or gray with white lime deposits ; capilHtium, a 

 regular network of small mesh with greenish-yellow lime knots ; 

 spores violet-brown, minutely spinulose, 8 to 10 m diameter. 

 Another gathering from Urumuwella has sporangia with white 

 or yellow hme deposits, stalks yellow or whitish, and lime knots 

 varying from yellow to white in the same sporangium. 



On decaying wood. Peradeniya, Urumuwela. 

 Physarum compactum, Lister. 



This species has been gathered on one occasion in Ceylon. 

 It occurred in fairly large numbers on small twigs cemented 

 together by earth. The sporangia are fairly typical, gray, 

 with circular white dense lime deposits ; capillitium almost 

 entirely composed of hyaline threads ; spores pale violet- 

 brown, minutely warted, 9 /x diameter. The stalks are white, 

 blackish at the base, either slender, '8 mm. high, or skoi'ter 

 and stout.
