On fallen oak-leaves. Common. — On almost every drv oak-leaf pale 

 spots occur, stiuldecl with minute shining black points, which arc, 1 

 presume, either the young state or perha[)s premature individuals of the 

 present species ; amongst these the perfect quadrangular plant is fre- 

 quently mixed, si)litting into about 4 laciniae from the centre to the 

 angles. The imperfect state mentioned above is the Sph. punctiforuiis 

 of Purton. P. Delta, Kunzc ! ap. HoU. Bot. Zeit. 1830. v. 1. p. 3G9, 

 appears to me merely a variety, with generally triangular perithecia.

On fallen leaves of the common Laurel. Very frequent. — Disc 

 yellowish when moist. Asci linear ; sporidia oblong, in a single row. 

 The finest and most perfect specimens I have seen were gathered by 

 Captain Carmichael and marked Peziza Lauri ; they have quite the 

 air of a true Peziza, the margin projecting greatly above the ej)idermis 

 and quite entire. I doubt whether the lacinias do not arise entirely from 

 the rupture of the epidermis. Sphccria Crattrlum and, if I mistake 

 not, Sph. Ilicis have nearly the same structure.

On trunks of trees. Conmion. — Captain Carmichael's specimens 

 have not the ainuilated sjunidia figured by Dr. (»revillc and which I 

 have verified in Fries' specimens, Scltr. Suec. u. ()1 ; though I d«» not 

 find ihcm so decidedly clavatc. They are probably the true Hi/st. 

 vnrium, Fr., but as 1 have seen no anlhentio sj)eciniens, 1 will not, in 

 this pn/./linj: genus, run the ri^k of committing an error.
