446 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 



Asci linear ; sporidia elliptic, uniseriate, hyaline, even, '001 inch 

 long, "0005 broad. 



Plate XV. fig. 19. a. asci with paraphyses, magnified; b. sporidia, 

 more highly magnified. 



1070. P. (Mollisia) Dematiicola, n. s. Gregaria, minutissima; 

 cupula hemispheerica, aquose umbrina, floccis longis hyalinis 

 ciliata; disco cinereo; ascis brevioribus; sporidiis subcymbi- 

 forrnibus, hyalinis. 



On dead wood, nestling amongst the flocci of some Helmin- 

 thosporoid Fungus ; but whether at all related to it, or not, we 

 cannot say. 



This very beautiful, though minute, species has a mixed re- 

 semblance to an Excipula and such Ascoboli as A. ciliatus. 



Plate XV. fig. 20. a. Ascus with bristles, magnified; b. sporidia, more 

 highly magnified. 



1071. P. (Calycina) minutissima, Batsch, fig. 143 (P. Helmin- 

 thosporii, Blox. MS.). Albida ; cupulis obovatis, substipitatis ; 

 margine incurvo ; hymenio concavo ; ascis clavatis, elongatis ; 

 sporidiis fusiformibus, 4-septatis, articulis tumidiusculis ; para- 

 physibus filiformibus. 



On Helminthosporia. Twycross, Rev. A. Bloxam. Batheaston, 

 Jan. 1864. 



Pallid; cups clavate, substipitate, margin incurved; sporidia 

 •0014 inch long, quadriseptate. 



This is undoubtedly the plant of Batsch, and very interesting 

 from the marked character afforded by the sporidia. 



Plate XV. fig. 21 . a. Ascus with paraphysis^ magnified ; b. sporidia, 

 more highly magnified. 



1072. P. (Mollisia) Browniana, Blox. MS. Cupula hemi- 

 sphserica, sessili, cornea ; margine pallidiore, ciliato ; disco pal- 

 lido; sporidiis breviter fusiformibus, hyalinis. 



On dead stems of Epilobium hirsutum. Twycross, Rev. A. 

 Bloxam. 



Allied to P. lacustris. That in Er. < Scl. Suec/ no. 173 has 

 sporidia '0008 inch long, uniseptate; that of Desm. no. 1064 

 has sporidia "0006 inch long ; while P. lacustris from Mr. Currey 

 has sporidia '0005-0006 long. The sporidia in Mr. Bloxam's 

 plant are -00045 long. The colour is paler, and, when perfect, 

 the ciliated margin, which consists of delicate, fiexuous, more or 

 less interwoven hairs, is characteristic. 



1073. P. (Mollisia) lacustris, Fr. Sc. Suec. no. 173.
