MYCETOZOA OF CEYLON. 3^3 



Trichia botrytis, Pers. 



Trichia pyriformis, Hoffm., in Berkeley and Broome, Fungi 

 of Ceylon, No. 775. Trichia fragilis, Rost., in Massee, Mon., 

 p. 176. 



Berkeley and Broome's No. 775 in Herb. Peradeniya 

 consists of crushed sporangia of var. lateritia, on simple, purple 

 or red-brown furrowed stalks, 1 -5 to 2 mm. long ; the mass of 

 elaters and spores is orange-red ; the points of the elaters are 

 short, measuring 20 to 30 /^. The specimen was collected at 

 Hakgala, which is still the only Ceylon station for this species, 

 though it is quite common there. In one recent gathering the 

 stalks are 4 mm. long. All the gatherings are var. lateritia. In 

 a gathering which approaches var. genuina the sporangia are 

 purple-brown, marked with ill-defined hghter hues of dehis- 

 cence ; they are 0"4 to 0*8 mm. in diameter, shortly stalked 

 or sessile ; stalks up to 0-5 mm. high, 0*3 mm. thick, purple- 

 brown ; elaters brownish-yeUow, with irregular bands, and 

 points about 20 A' long ; spores 10 /^ diameter, minutely 

 spinulose ; in the short points of the elaters it resembles var. 

 suhjusca, but the elaters are not so yellow as in Rex's type. 

 Ceylon forms of T. botrytis are almost always simple, not 

 clustered. In some cases there is a well-developed red-brown 

 hypothallus. The sporangia are usually shining purple-black, 

 with elaters red-brown in mass. 



Hemitrichia rubiformis, List. 



Arcyria rubiformis, Mass., Mon., p. 158. 



Thwaites' 22, in Herb. Peradeniya, is this species ; it was 

 included by Berkeley and Broome under Arcyria punicea, 

 Fungi of Ceylon, No. 770 ; the sporangium wall is red-brown, 

 the orange-red capillitium has no swelhngs, and the spores are 

 spinulose, 10 ^ diameter. In two recent gatherings the spo- 

 rangia dehisce by a distinct lid, and in one the inner threads of 

 the capillitium lack spines ; the spores are 8 to 10 /< diameter. 



Peradeniya, Hunugalla. 



Hemitrichia intorta, Lister. 



A gathering from Hakgala was referred to H. intorta var. 

 leiotricha by Mr. Lister. The sporangia are shining olive 

 (rose pink when unripe), sessile, scattered, globose, 0*5 to 1 mm.
