Under the lens the coat consists of very short flocci, intermixed 

 with minute hyaline amorphous scales. We cannot point out 

 any very near ally, except possibly P. humilis, Desm. It re- 

 sembles P. apala more closely than any other species with which 

 we are acquainted. 



771. P. (Dasyscyphse) aspidiicola, n. s. Nivea, sicca sub- 

 alutacea, stipite brevissimo; cupula concava subhemisphaerica 

 extus furfuraceo-floccosa. On dead stems of Aspidium filix mas. 

 Orton, Leic, Nov. 1851, Rev. A. Bloxam. 



Very minute, gregarious, white, rather buflF when dry. Stem 

 extremely short, gradually passing into the subhemispherical cup, 

 which is clothed externally with minute pellucid scales, mixed 

 with a few obscure hyaline flocci. Asci very short and slender. 

 Sporidia •0002 inch long, oblong, subclavate. 



Resembling in its investing coat P. Berkeleii, but diiFering in 

 colour, in the distinct stem, more open disc, and in the more 

 minute sporidia. P. Aspidii, Libert, is a more minute species, 

 of a purer more persistent white, and with a more tomentose 

 coat. 



772. P. (Fibrina) siparia, n. s. Cupulis subsessilibus extus 

 furfuraceis ochraceis, hymenio fuscescente ; sporidiis lineari- 

 oblongis cm-vis. 



On decorticated elm branches, Elmhurst, Oct. 1, 1853. 



Accompanied by a floccose stratum, which is however possibly 

 not constant. Cup at first subglobose, then cyathiform, scarcely 

 stipitate, but fixed by a broad base with the margin free, externally 

 ochraceous, furfuraceous ; hymenium ochraceous, at length 

 brownish ; sporidia linear-oblong, '00045 inch long, curved, often 

 with a nucleus at either extremity. 



This has at first some resemblance to P. firma, but the sporidia 

 of that species are subelliptic, pointed at either end, and '0007 

 inch long, not to mention other distinctive characters. 



773. P. (Mollisia) micrometra, n. s. Minutissima sessilis sub- 

 turbinata villo albo affixa bninneola, ore subcontracto subtiliter 

 striato. 



On dead stems of Juncus, Twycross, Rev. A. Bloxam. 



Extremely minute, punctiform, subturbinate, attached by 

 strong \-illoud hairs, smooth above ; orifice somewhat contracted, 

 marked with close parallel lines, horn-brown ; hymenium plane. 

 Asci clavate ; sporidia filiform. A very singular though extremely 

 minute species, to which we can point out no close ally. 



774. Patellaria clavispora, n. s. Mollis, junior sparsa sub- 

 globosa, senior expansa subirregularis picea; sporidiis clavae- 

 formibus 4-^6-septatis. On twigs of privet, Luckram, Wilts., 

 Nov. 4, 1852. 



When young nearly globose, in age expanding, pitch-brown,
