MYCETOZOA OF CEYLON. 345 



6 cm. long and 1 cm. or more broad, with a few large oval gaps 

 and many minute perforations. In another gathering of small 

 flat elongated plasmodiocarps there is a slight white hypothal- 

 lus; the outer surface of these is rough, and lined as though 

 with a brush.

" Diderma depressum, Fr.," B, & Br., Fungi of Ceylon, 

 No. 744. 



Thwaites' No. 1044, included in Berkeley and Broome's 

 No. 744, consists of shortly stalked sporangia of C. michelii, 



07 to 1 mm. diameter, with a few sessile, in Herb. Peradeniya. 

 A fairly frequent species at Peradeniya on dead leaves ; 

 sporangia up to 1 mm. diameter ; stalk and under surface 

 sometimes chocolate-brown, or brown with white lines ; the 

 outer layer often falls off round the edge of the sporangium and 

 leaves a brown rim. 



Peradeniya. 



Chondrioderma rugosum, Rex. 



Fairly frequent on trunks of jak trees {Artocarpus integri- 

 folia), sometimes also on dead twigs. Sporangia typical, 

 grayish -white, areolated, on furrowed black stalks ; total 

 height about 0*8 mm. ; stalk and base of sporangium red-brown 

 when mounted ; columella white or yellowish ; capillitiurn 

 colourless ; spores 8 to 10^, violet-brown, minutely warted. 



Peradeniya, TalawakeUe. 



With C. rugosum, there occurs on the moss and dead bark 

 on the trunks of j ak trees a sessile form which is most probably 

 a plasmodiocarp form of that species. The plasmodiocarps 

 are small, elongated, or oval, or circular, from 0*3 mm. 

 diameter to 2 x 0*75 mm., white, strongly wrinkled, base 

 pale brown or reddish-brown internally ; capillitiurn of daxk 

 brown threads, 4 to 6 /* in diameter, often nodular, united by 

 broad perforated sheets, and terminating at the outer ends 

 in paler triangular expansions, up to 45 /^ broad; spores, 

 13 to 18 /^ diameter, violet-brown, closely and minutely 

 warted. •
