GENERIC CHARACTER.
Massa sporulifera gelatinosa, informa cyrrhorum, ex splioerulis immersis, mam-
feslis aut ohsoletis, erumpens. Cyrrhi in aqua solubilis. Sporuloe minutæ.
A gelatinous sporuliferous mass, bursting from immersed, obvious or indistinct
spherules, in the form of tendrils. Tendrils {cyrrh) soluble in water.
Sporules minute.
S PE C IF IC CHARACTER.
N æ m a s p o r a Rosarum ; Cyrrhus sporuliferus albidus, simpkx. Sphoeruloe sec-
tione horizontale sinuatoe, sub epidermide manifestoe, ore mgro margine tomen-
toso albo.
N. sp o ru life ro i tendril, white, simple. Spherules waved; when divided
horizontally, manifest under the epidermis ; mouth blackish, and furnished
with a tomentose or cottony margin.

Minute, slightly prominent, gregarious. Spherules under the epidermis chs-
tinct, soft, blackish-brown, the margin appearing much waved m a horizontal
section. Orifice black in the centre, with a whitish cottony
margin. Sporuliferous mass escaping in the form of a simp e, minute, filiform,
whitish tendril, which is sometimes short, and merely curve .
It is to be feared tbat Næmaspora maybe found eventually
to border too closely upon many species of the old genus
Sphæria; some of which have a tendency to discharge their
sporules in the form of tendrils. Until, however, the relatmn
which the individuals of so extensive a family bear to each
other can be established, Næmaspora must remain as it is.
The spherules certainly do not appear to be so regular in their
form as in the Sphoerioe in general, and to be also of a muc
less corneous nature. A t present, there are but few species
