not form a continuous stratum. When fresh the whole plant is 

 white^ but when dry the disc acquires a yellow tinge. Asci slightly 

 clavate or obtusely lanceolate, sporidia oblong. 



This species has very much the habit of P. porioides, but differs 

 in its tomentose flat cups and scattered mode of growth. Its 

 nearest ally however is P. Chavetice, Libert, which perhaps is the 

 same species with P. casia. From both of these it differs in its 

 larger cups, pale disc, and in several other points. The cups are 

 sometimes extremely thin, crowded, and pressed very close to the 

 matrix, but this is not usually the case.

Forming a uniform stratum on decayed sticks. Cups half a 

 line broad, at first brown and pulverulent, at length rufous, 

 rather thin with a satiny lustre, subturbinate, with the margin 

 permanently inflected, at first quite closed. Subiculum granu- 

 lated, grumous, obscurely floccose. 



I have seen no other specimen of this remarkable species, which 

 has some resemblance to P. fusca, but is in reality extremely 

 different, and has rather a tropical than an European habit. If 

 the figure of P. fusca by Letellier be not exaggerated, it may pos- 

 sibly be the same species, but I am inclined to think such is not 

 the case. 



I have in vain waited to obtain further information respecting 

 this species, and am now unable to give any account of its fruc- 

 tification as I cannot find any perfect asci. 



The specimens given for P. fusca, no. 286 in the fourth Fas- 

 ciculus of ' British Fungi,' do not belong to that species, but are a 

 variety of P. Rosa growing on sycamore. They were gathered 

 at Spcke Hall near Liverpool.

 This species appears to me to be the same with Hysterium rufum, 

 Fr., but my specimens of that species are not so good as might 

 be wished.
