Gen. LXX XII. SPHÆRIA, Hall.
Stroma nullum vel spurium, mycelioideum. Perithecia varia, firma, verticalia, nigra vel fuliginea, sæpe
corticata. Ostiolum breve. Asci perfecti. Sporidia ut plurimum octona.
A very large genus, consisting of those species which have no stroma, and whose perithecia have a short
ostiolum. They are found in all parts of the world, but more especially in temperate regions. (Name from
<T(j>aipa, a sphere)

Densely crowded. Perithecia astomous, rugulose, at length by collapsing saucer-shaped, Asci clavate. Sporidia
biscriate, elongated, curved, quadrinucleate, ^ inch long.--This species at first sight looks very like 8. phao-

Gen. LXX X III. CERATOSTOMA, Fr.
nullum 1. myceliiforme. Perithecia membranacea, nuda, verticalia. Ostiolum insigniter elongatum,
apice penicillatum.
This genus comprises those simple Spharia which have extremely long ostiola ciliated at the tips, and of a soft
membranaceous substance. The sporidia moreover are expelled from the ostiola, and often remain attached. (Name
from Kepas, a horn, aud crropa, a mouth)
1. Ceratostoma caprinum (Fr. Summ. p. 896).
H a b . On dead wood, Archer.
It has the same white, flageUiform orifice when perfect as S. vervecina, Desm., but it has no subiculum, and the
sporidia do uot exceed inch in length, though they are frequently shorter,
Gen. LXXXIV. GLONIUM, MUhl.
Periihedum liberum, compositum e ramis radiatim excurrentibus teretiusculis prostratis, rima longitudinali
dehiscens. Subiculum byssinum.
This curious genus is distinguished from Hysterium by its free, very compound perithecia. It is a very unexpected
inhabitant of Tasmania, being hitherto confined to the United States and the north of Europe. (Name from
xAtiJviov, in allusion to the linear orifice of the perithecia.)

Gen. LXXXV. HYSTERIUM, Fr.

Approaching very near to the Opegraphoid Lichens, but distinguished by the total absence of crust. Essentially
plants of temperate regions. (Name from rarepov, in aUusion to the mode of dehiscence.)
1. Hyster ium tardum (Berk.); peritheciis ellipticis obtusis tarde apertis, ascis brevibus, sporidiis

H a b . On the under side of the leaves of Cyathodes straminea, J. I). H.
Ou the under side of the leaves. Peiitlacia flat, elliptic, very obtuse, opening principally in the centre. Asci
short, thick. Sporidia subclavate, uniseptate, inch long, with a hyaline border. This species is almost
intermediate between Hysterium and Phacidium. A few specimens only show any trace of an aperture.
