210 -DECADES OF FUNGI 



474. Peziza ceruginea, n. s.; cupiilis cyathiformibus subregularibus, 

 extug serugiueo-obsciiris, intus pallidioribus ; mycelio lignum super- 

 ficialiter tingente ; sporidiis subfusiformibus majoribus. 



On dead wood. Khasia. (Hooker and Thomson.} 



Cups about 1 line across, scattered over the surface of the wood, 

 which is strongly but not deeply tinged with green ; nearly regular ; 

 dark metalUc-green externally. Stem about as high as the cups, at- 

 tenuated downwards, dark green. Hymenium paler; asci linear; spo- 

 ridia subfusiform, a-Arrt o^ ^ii iiich lonoj. 



This is closely allied to P. (Bruginom^ but not only are the cups 

 more regular and smaller, and the tint darker, and the wood stained' 

 more superficially, but the sporidia are half as long again as those of 

 that species, with a proportional increase of width. The sporidia in 

 P. cernghiom are about -5-^3^ of an inch long. 



475. Rhytwna picetim^ n. s. ; orbiculare sublobatum opacum piceum 

 centro depressum rugosum ; margine Isevi. 



On living leaves of Pieris. Tambur Valley, E. Nepal. (Dr. Hooker.) 



Orbicular, 5-6 lines broad, opake, very thin at the extreme edge, 

 where it is more or less lobed, then slightly swollen, depressed and 

 rugose in the centre. In less perfect individuals the patches are broken 

 up, and the natural order disai'ranged. 



Most resembling E, decolorans^ Schwein. Unfortunately the fruit is 



not perfect. 



* Phacidium ceuthocarpa^ Fr. 



Hab. On large poplar-leaves {Popuhis ciliata), Khabili river. 6000 

 feet. (Dr, Hooker.) 



This is no Sphceria, but more properly a Phacidium. The specimens 

 are unfortunately old, but they show a distinct naked disc, with oblong, 

 minute, subclavate spores, like those so common in some Pezizce^ which 

 I have not seen in the published specimens, in which however there 

 is not a trace of perithecia. 



476. Ader'ma aspersa^ n. s. ; subiculo tenuissimo, margine subradi- 

 ante ; ascis sporidiisque oblongis. 



Hab. On the under side of the leaves of some species of Lanriis. 



Khasia. (Dr. Hooker.) 



Spots having exactly the appearance of being formed by drops of 

 dirty water dashed upon the leaves, distinct, black, extremely thin, 

 somewhat radiating towards the margin. Peiithecia punctiform, open- 

 ing with a minute, round ostiolum. Asci and sporidia oblong.
