somewhat irregular, soft ; substauce beneath the hymenium paler. 

 Asci cylindric ; sporidia elongated, clavate, '001 inch long, 4-6- 

 septate ; paraphyses branched, bearing at their tips one or more 

 dark bodies, sometimes arranged like the joints of a necklace. 



The fructification of this species is so remarkable that there 

 can be no difficulty in recognizing it, though its external appear- 

 ance does not differ greatly from that of some other species. In 

 an unpublished species, 2\ Ravenelii, B., there is a similar deve- 

 lopment of the tips of the paraphyses. 



775. P. livida, n. s. Gregaria ssepe congesta subhemi- 

 sphrerica sessilis olivaceo-lutea margine albido, extus subtiliter 

 sericea. 



Abundant on fallen firs, Gopsal Park, Leicestershire,Dec. 1 851 . 



Minute, gregarious, often ci'owded, olivaceous yellow, greyish 

 when dry, sessile, hemispherical, fixed by a small point, minutely 

 silky externally, margin dirty white. Hymenium plane. Asci 

 subfusiform, bulging in the centre, often geniculate; sporidia 

 oblong or elliptic, perhaps immature. 



This species has a Lichenoid aspect, but has no crust whatever 

 and is certainly undescribed. It resembles in general appearance 

 Patellaria carpinea, with which it agrees closely in fruit. P. rha- 

 barbarina also is closely allied.

Asci containing four sporidia, varying greatly in length, but 

 sometimes as much as "002 inch.

This curious production is considered by Montague a Discomy- 

 cete near Agyrium, and by Tulasne a Lichen. We are not in a 

 position to decide so knotty a point, but we have great pleasure 

 in recording the discovery of so curious an object by Mr. Piggot.

At first covered by the cuticle, then exposed, haK immersed ;

 nuclei, and with two constrictions.
