identity of Euroiium diphcystis was left in abeyance until the 

 Kew specimens had been examuied. Recently, however, a 

 gathering of the Sclerotium made at Peradenij-a was found to 

 contain another species as well, which might be Eurotium 

 diplocijsiis, from which it appeared probable that the same 

 thing might have occurred when Thwaites collected the latter 

 species. Examination of the tj^pe specimens of Eurotium 

 diplocijsiis at Kew has confirmed this supposition ; at least 

 six of the nine specimens agree with the species recently 

 collected in company with the Sclerotium. This species is 

 Onygeiwpsis Engleriana P. Henn. 



The type specimen at Kew is labelled Diplocysiis fiava 

 B. & Br., while the cover is labelled [Eurotium) flavum. 

 Apparently neither of these names was published. The 

 description evidently refers to the Onygenopsis, not to the 

 specimens which were returned to Peradeniya. 



As Onygenopsis Engleriana has only been described from 

 dried siiecimens, the follo\\'ing notes may be of use. This 

 species grows on dead leaves or twigs to which the fructification 

 is attached by a white basal weft of hyphae. It is sessile, 

 hemispherical or subglobose, 2-6 mm. in diameter, sometimes 

 pulvinatc, elongated, up to 6 x 3 mm., rough, white or 

 yellowish, becoming ochraceous in drying. It consists of a 

 central core of interwoven hyphae which form a loose pseudo- 

 parcnchymatous tissue, surrounded by an outer zone of asci 

 with a few hypha) intermingled. The asci are borne singly, 

 the ends of branching hyphaj ; they are oval, 30 X 45 ^, or 

 globose, 30 X 4.") [j. diameter ; most of them arc sixteen-spored , 

 but some arc eight-spored ; the spores arc smooth, hyaline, 

 internally granular, oval or globose, 13-21 X 10-10 (j.. There 

 is scarcely any peridium ; here and there a few hypha? overrun 

 the mass <if asci. The whole fructification appears rough 

 when magnified, i)ccause the individual asci are then 

 evident. The name will now stand as Onygenopsis diplocystis 

 (B. & Br.).
