MYCETOZOA OF CEYLON. 333 



liigh, 160 A* diameter at the base, 30 A* diameter at the apex ; 

 capillitium of hyaline threads with few lime knots ; wall 

 containing somewhat rounded, white lime deposits ; spores 8 a* 

 diameter, minutely warted. Var. hucojyhceum, from ITkuwela, 

 has cernuous stalks, typical flattened sporangia, abundant 

 white lime knots, and closely warted spores, 12 to 13 ^> 

 diameter ; another gathering of this variety, from Gangaruwa, 

 has dark furrowed stalks with white ridges. Var. robustum, on 

 moss on the trmik of a jak tree, Peradeniya, consists of plas- 

 raodiocarps with spinulose spores, 9 to 11 fi diameter. 



Peradeniya, Gangaruwa, Ukuwela, Badureliya, Pattipola, 

 Hakgala. 



Physarum calidris, Lister. 



Fairly common. Sporangia usually typical, but in one 

 instance very shortly stalked, almost sessile. Spores violet- 

 brown, 10 yu diameter. " The specimen in Broome's herbarium, 

 named Physarum elephantinum, B. & Br., MS. from Ceylon 

 (B. M. 453), is a somewhat large form, but appears to be the 

 same species, with capillitium and spores similar to those in 

 the EngHsh gatherings " (Lister, Mon., p. 52). This name was 

 not published in Berkeley and Broome's Fungi of Ceylon, and 

 there is no specimen in Herb. Peradeniya. The specimens 

 would appear to be similar to those of recent gatherings at 

 Hakgala, in which tlie sporangia are "75 mm. diameter, total 

 height up to 2 "3 mm. ; the upper two-thirds of the sporangium 

 is covered with large, dense lime deposits, the lower third being 

 smooth and dark ; spores 10 /^ diameter, minutely spinulose. 



In various locaHties, usually on twigs, at Peradeniya, Ban- 

 darawela, Hakgala, Pattipola. 



Physarum compressum, Alb. and Schw.

Thwaites' specimen No. 68, which was at first named 

 Didymium leucopus, Link., by Berkeley and Broome, and 

 which furnished the type specimens of Physarum affine, Rost.,
