MYCETOZOA OF CEYLON. 351 



This species differs from Lepidoderma tigrinum in tlie stellate 

 crystals, the stout areolated sporangium wall, the thin wall of 

 the columella, and the paler, small spores. Of three recent 

 gatherings, the sporangia are ochraceous or yellow in two, 

 and pale tawny to almost white in the third. 



Peradeniya. 



[Spumaria alba, DC. 



This species is recorded for Ceylon in Massee, Monograph, 

 p. 256, but it was not recorded by Berkeley and Broome, nor 

 are there any Ceylon specimens at Peradeniya, Kew, or the 

 British Museum.] 



SUBCOHORT II.— AMAUROCH^TINE^.

Stemonitis fusca, Roth. 



Stemo7iitis fusca, Roth., in Berkeley and Broome, Fungi of 

 Ceylon, No. 766. Stemonitis dictyospora, Rost., in Berkeley 

 and Broome, Fungi of Ceylon, No. 1195. 



A common species, with the usual amount of variation in the 

 capilhtium and spores. One Peradeniya gathering shows a 

 feebly developed net with meshes up to 80 /.t broad, resembling 

 S. splendens, but the spores are reticulated. The spores 

 of the Ceylon specimens range from 6 to 9 ^t diameter. On 

 one occasion a large development was found on the surface of 

 a recently-dug flower bed, distributed over an area measuring 

 4 feet by 3 feet ; a few dead leaves were scattered over the 

 surface, but nearly all the sporangia had developed on lumps of 

 earth and on stones. Vars. oc genuina and /3 rufescens are 

 equally common.

Fairly common. Thwaites' gathering of this species was 

 included under Stemonitis fusca ; in his specimen in Herb. 

 Peradeniya the meshes of the net are 18 to 60 a* wide, with
