 villosa; hymenio aurantio; sporidiis oblongis asperulis. 



On manured ground^ Penzance, Mr. Tracey Millett. 



Sessile, | of an inch broad, depressed, attached to the soil by 

 villous down ; margin free, clothed with delicate obtuse articulate 

 hairs ; hymenium orange. Asci subcylindrical ; sporidia oblong,

768. P.glumanim, Desm. no. 1054. On chaff in a farm-yard, 

 Batheaston, Dec. 1853. 



The following measurements of the sporidia of Pezizce may be 

 useful : — 



P. humosa, -OOOQ-'OOl inch long by •0004--0005 ; the Black- 

 heath plant mentioned in the ' English Flora.' 



P. Polytrichi, •0007--0008 inch long by '0007 wide. An ana- 

 lysis of this species is given in PI. XVI. fig. 14*, in consequence 

 of the highly developed paraphyses and the curious processes 

 which they often bear at their side. 



P. scutellata, "0008 inch long by '0005 wide. 



P. hirta, -0009 inch long by '0005 wide, from Wareham; -0006 

 inch long by '0003 wide, from Bowood. 



P. leucoloma, '0008 inch long by "0004 wide, in the plant so 

 named in ' English Flora.' 



P. trechispora, •0008 inch in diameter. 



769. P. (Tapezia) Piggotii, n. s. Media mycelio lanoso 

 candido, cupulis subhemisphsericis vel cyathiformibus leviter con- 

 cavis, hymenio pallide lateritio. 



On the plaster ceiling of a cottage, Chelmsford, H. Piggot, Esq. 



Mycelium white, downy, but not spreading very widely, running 

 up the base of the hemispherical or cyathiform cups which are 

 about 2 lines broad ; hymenium pale brick-red ; margin generally 

 acute. Asci cylindrical, paraphyses linear ; spores elliptic, with 

 a single, very distinct nucleus, in the centre of which is a bi'ight 

 point, -0005 inch long by -0003 wide. 



Allied to P. argillacea, Sow. P. dumestica is a far smaller 

 species, with spores -0006 by -0004 inch. 



770. P. (Dasyscyphse) Berkeleii, Blox. MSS. Gregaria sessilis, 

 cupulis hemisphsericis furfuraceo-floccosis quandoque pruinosis, 

 hymenio concavo fulvo. 



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



Very minute, gregarious, often crowded, hemispherical, with 

 the margin at first strongly inflected, clothed with furfuraceous 

 yellowish fliocci. In the younger specimens the orifice is distinctly 

 marked with radiating lines. Hymenium concave, tawny. Asci 

 clavate ; sporidia '0003 to -0004 inch long, oblong, subfusiform 

 or cymbiform.
