Orbicular, shield-like, depressed, somewhat immersed, black ; 

 asci clavate; sporidia biseriate, oblong, obtuse at either end, 

 slightly curved, 4-5-septate. 



Closely resembling P. atrata, but differing materially in the 

 fruit.

967. Phacidium simulatum, n. sp. Erumpens cupulari-linearis, 

 margine irregulari ; disco linear! rufo-fusco ; sporidiis obovatis. 



On dead stems of Clinopodium. Langridge, Somers., C. E. 

 Broome. 



Linear, but cup-shaped, erumpent, with an irregular margin ; 

 disk linear, red-brown; asci clavate; sporidia obovate, '0004 

 inch long, binucleate.

 sporidia. 



968. Ailographum maculare, n. sp. Peritheciis utplurimum 

 simplicibus subconcentricis in maculas orbiculares dispositis; 

 ascis brevibus oblongis ; sporidiis oblongo-clavatis. 



On an old mat made of Typha. Hainault Forest, May 1859. 



Forming little orbicular black patches, in which the perithecia 

 are disposed in a somewhat concentric fashion ; perithecia mostly 

 simple; asci short, oblong ; sporidia oblongo-clavate, 0*0005 inch 

 long. Mycelium matted, brown, producing here and there dark 



Very distinct in habit and in the longer asci. 



Plate XVI. fig. 21. a. Plant, nat. size; b. the same, magnified ; c. asci; 

 d. sporidia; e. threads of the mycehum. (All but the first magnified.) 



969. Cordiceps pistillariaformis, n.sp. Pusilla, clavula fusca, 

 stipite cylindrico pallido basi dilatato subsequali. 



On wych-elm twigs. Batheaston, Nov. to Feb., C. E. Broome. 



Plant 2 lines high ; head oblong-ovate, granulated from the 

 perithecia which are sunk in its substance, rather longer than 

 the pallid cylindrical stem, which is slightly swollen at the 

 base. 



This curious plant has not, at present, been gathered with per- 

 fect fruit. It grows on a sclerotioid substance ; but whether a 

 part of it or not, we are unable to say.
