779. >S. (Caulicolse) F<?c^w, n. s. Subcuticularis ostiolo demum 

 nudo ; ascis brevibus cylindricis sporidiis oblongis 5-septatis, 

 articulo quarto tumido. 



On dead leaves of Iris fostidissima, Isle of Wight, Rev. A. 

 Bloxam. 



Covered by the cuticle, which is at length pierced by the black 

 ostiolum, sometimes regularly diffused, sometimes forming little 

 pale patches; asci short, curved, cylindrical; sporidia oblong, 

 •0001 inch in length, 5 -septate, the fourth joint being much 

 swollen. 



Plate XVI. fig. 16. Asci and sporidia magnified. 



^Nectria ochraceo-pallida, (B. and B.), var. corallina. On 

 elder, Gopsal, Rev. A. Bloxam. On elm, King^s Cliffe. 



Rather smaller than the paler plant and less depressed, but 

 there is so little difference in the fruit that we think it better 

 not to distinguish them. [. 



780. Nectria Ralfsii, n. s. Csespitosa ; peritheciis crassis 

 aurantiacis furfure albido dense inspersis, siccis fortiter coUapsis ; 

 ore obscuro papillseformi ; sporidiis elongatis uniseptatis. 



On dead branches, apparently of beech. Penzance. Also oi^ 

 furze, of a delicate salmon colour. ,\^ 



Csespitose. Perithecia orange, globose, but strongly collapsed, 

 when dry covered with whitish furfuraceous scales ; mouth 

 generally obscure, sometimes minutely papillseform. Asci clavate, 

 sporidia oblong, elongated, uniseptate, with one or two nuclei in 

 each division, varying greatly in size from "0006 to '001 inch in 

 length. The hymenium is sometimes exposed, apparently from 

 the circumcision of the upper portion of the perithecium. 



Allied to N. cinnabarina, but presenting many points of di- 

 stinction, especially in its generally elongated sporidia. 



781. N. Bloxami, B. and B. Sparsa cinnabarina peri- 

 theciis fortiter collapsis subglabris, sporidiis elongatis subfusi- 

 formibus quadrinucleatis. 



On dead stems of herbaceous plants, Twycross, Rev. A. Bloxam. 



Scattered, dark cinnabar red. Perithecia nearly smooth, 

 strongly collapsed. Sporidia elongated, subfusiform, quadi'i- 

 nucleate, -00065 inch long. 



This species differs from N. ochraceo-pallida and its coralline 

 variety, not only in its dark cinnabar hue and collapsed perithecia, 

 but in the far more delicate and shorter sporidia. There is 

 sometimes a single very obscure septum. 



781*. N. inaurata, n. s. Caespitosa, peritheciis globoso-de- 

 pressis quandoque rubro-tinctis fuscis, flavo-pruinosis, ostiolo 

 papillseformi demum impresso nudo atro-fusco ; ascis sporidiisque 

 biformibus, aliis clavatis sporidiis minimis innumeris curvulis,
