MYCETOZOA OF CEYLON. 315 



753. D. hulhillosum, B. & Br. Stipite conico albo Isevi, 

 basi bulbilloso ; peridio globoso farinaceo ; sporis floccisque 

 nigris conglameratis (No. 21 in part). On dead leaves. Pera- 

 deniya, Nov., 1867. 



There is no specimen of this in Thwaites' 21 in Herb. 

 Peradeniya. It occiu-s in British Mxisemii 592, and Kew 1514, 

 under the supposed Thwaites' number 1854. But there is some 

 error here, since Thwaites' numbers did not exceed 1250 ; 1854 is 

 probably a date. The specimens are Diachcea bulbillosa (B. & 

 Br.), List. 



704. D. zeylanicum, B. & Br. Stipite elongate, sursum 

 attenuate, rufo ; peridio globoso umbilicato candido ; capillitio 

 pallido vel candido ; sporis nigris. On dead wood. Ceylon, 

 1851 . Threads pale or entirely white : spores -0004 in diameter. 



This is one of Thwaites' earlier consignments ; it has therefore 

 no collection number, and is not in Herb. Peradeniya, The 

 specimens inxder this name in Kew 1520, and British Museinn 

 576, are Trichmnphora pezizoidea, Jungh., but through some 

 confusion they are under Thwaites' number 1046, which is B. & 

 Br. 1190, i.e., Badhamia nitens. A previous description of 

 Didyniium zeylanicum was given by Berkeley in Hooker's 

 Journal of Botany and Kew Gardens Miscellany, Vol. 6 (1854), 

 p. 230. — '^ Didymium zeylanicum. n.s. Peridio ienticulari subtus 

 umbilicato cretaceo demum fatiscente subtiliter pulverulento ; 

 stipite sursum attenuate elongate sulcato fulvo ; caj)illitio 

 candido ; sporis nigris. On dead wood. Ceylon (G. H. K. 

 Thwaites), Stem 1 line high, tawny, incrassated below, 

 attenuated above, sulcate, attached to a sliining hypothallus* 

 Peridium lenticular, umbilicate beneath, chalky, white, at 

 length cracking, delicately pulverulent. Capilitimn white, 

 branched, anastomosing here and there, stained with a fuliginous 

 tinge, very variable in thickness. Spores globose, 1/2500 of an 

 inch in diameter. This siDCcies resembles in some respects Phy. 

 nutans ; but not only is the stem sulcate, but the peridimn is 

 decidedly pulverulent, like a leaf covered with Oidium. When 

 tlie i^owdery coat is rubbed it ap2)ears rugged, like the surface 

 of an egg." There is no doubt that both descriptions refer to 

 the same gathering. 



755. D. effusum, Lk. (No. 1024). On dead leaves. Pera- 

 deniya, Jan., 1869. 



1024 is apj)arently not represented at Kew or the British 

 Museum : in Herb. Peradeniya it consists of two pieces of wood
