PEZIZA TRACHYCARPA, n.S. Prima state orbicularis, fere plana, et sepissime umbilicata ; 
demum irregularis, recurva et undulata; discus nigro-fuscus, asper et tuberculatus. 
Cupula 4 ad $ uncize lata, solo adpressa, extrinsecus minute granulata, substipitata, 
vel obconica. Paraphyses biformes; aliz filiformes, apicem versus aliquanto cla- 
vate; alie latze et pallide fuscæ, ascis vacuis simillimze. He fere multum corru- 
gate, hymenii sectioni aspectum mirum sub microscopio prebentes. Sporidia uni- 
seriata, penitus globosa, muricata, fusca, 00005 uncis lata. Supra solum deustum, 
Ascot com. Surrey, Nov. 1863.  Sporidia, licet sub microscopio fusca, supra chartam 
nigram demissa albo-grisea sunt. 
PEZIZA LEIOCARPA, n.s. Cupula prima setate connivens et subglobosa, extrinsecus, et 
presertim versus marginem, aspera, fusco-vinosa, tenuis, et semipellucida, basin 
versus sspe pallida, sessilis, 3 ad $ uncis lata; demum expansa et fere plana, irre- 
gularis, varie lobata et undulata. Discus olivaceo-fuscus, primum pallide, demum 
obscure. Sporidia penitus globosa, nunquam non levia, uni- vel bi-seriata, coloris 
expertia, 0*0003 ad 0:0004 unciæ lata. Paraphyses et habitat ut in P. trachycarpa. 
Prima tate heee planta figuram Batschianam P. pustulate, Fr., fere repreesentat. 
Plate LI. fig. 3 represents a small specimen of Peziza trachycarpa, of the natural size ; 
and fig. 4 an average-sized specimen of P. leiocarpa, also of the natural size. Fig. 5 
shows an aseus with sporidia of P. trachycarpa, magnified 430 diameters; and fig. 6 the 
asci and sporidia of 2. leiocarpa, similarly magnified. 
RHIZINA UNDULATA, Fr. Syst. Myc. ii. p. 33. 
In the autumn of last year (1863) beautiful specimens of a species of Rhizina were sent 
to me by the Rev. G. H. Sawyer. From these specimens figs. 7 & 8 of Pl. LI. were drawn. 
I should have felt considerable doubt as to the species but for the exact identity of the 
fruit with the figure given by Tulasne, in his * Fungi Hypogzi,’ of the fruit of R. undulata. 
The plant shown in fig. 7 agrees, except in colour, with Fries’s description of the adult 
form of R. undulata. In colour it comes nearer to R. levigata, B. pretexta. Fries seems 
to doubt whether R. undulata and R. levigata are distinct; for in speaking of the latter 
he says, * Quin prioris congener sit, nullus dubitet, potius de specifica differentia." The 
margin in fig. 8 is of a decided yellow colour, differing in this respect from both Jz. undu- 
lata and R. levigata. 
The genus has not hitherto been recorded as British. Plate LI. fig. 9 represents an 
ascus with sporidia, magnified 480 diameters. The sporidia are colourless or yellowish, 
measuring from 0:0012 to 0:0014 of an inch. 
RHIZINA NIGRO-OLIVACEA, n. S. 
Disk at first circular, 1 to 2 inch across, dark olive-green ; margin of a greenish brown, 
strongly incurved, ribbed, and granular. Disk ultimately effused, i inch or more across, 
dark olive-green, with a narrow brown margin, the latter very slightly, if at all, incurved. 
Sporidia in asci, eight in number, elliptical or slightly turbinate, of a clear tee
