MYCETOZOA OF CEYLON. 367 



[Arcyria incarnata, Pex-s. 



This species was recorded by Berkeley and Broome, Fungi 

 of Ceylon, No. 771 (Thwaites' 115). It is also recorded for 

 Ceylon b}^ Massee, Mon., p. 145. Thwaites' 115 is apparently 

 not in any herbarium at the present time ; it was not found 

 by iVIr. A. Lister at Kew or the British Museum. At Pera- 

 deniya, Tliwaites' Nos. 20 and 115 are .marked on one 

 packet, which contains Arcyria punicea (No. 20) only. Flesh- 

 coloured examples of Arcyria punicea are quite common, but 

 although I have examined all the numerous growths of 

 Arcyria seen dm-ing the last four years, I have not met with 

 Arcyria incarnata. I am inchned to believe therefore that 

 the Ceylon record of this species is an error.] 



Arcyria stipata, List. 



" Arcyria punicea, Fr. ," in B. & Br. , Fungi of Ceylon, No. 770 

 (Thw. 70). 



Thwaites' 70 consists of a bright scarlet mass of crushed 

 sporangia; the stalks are 075 to 1-25 mm. liigh, and the 

 sporangia 1'75 to 2*2 mm. ; the threads within the cup are 

 smooth, darker than the outer threads, and have a horny 

 appearance ; the cog-hke thickenings are almost square and 

 close set. In recent gatherings from Hakgala and Peradeniya 

 the sporangia are bright or duU scarlet ; the spiral bands 

 are only evident in a few places, generally most conspicuous 

 in the lower part of the capillitiuni, where the threads are 

 almost smooth. The capillitiuni of tliis species appears to 

 be more rigid than that of other Arcyrias. 



Peradeniya, Hakgala. 



Arcyria flava, Pers. 



Arcyria nutans, Fr. , in B. & Br., Fungi of Ceylon, No. 772. 



Not common. Thwaites' specimens have rather long stalks 

 measuring, with the cup, about 1 mm. in length. Recently 

 collected at Peradeniya and Hakgala. 



Arcyria (Erstedtii, Rost. 



A single gathering from Peradeniya. The stalks are weak, 

 up to 0'5 mm. long, and the cup is small ; the expanded 

 cylindrical sporangia are 5mm. , or more, long; there is a 

 well-developed, white or hyaline, shining, membranous
