Gen. LXI. POLYACTIS, Lk.
Flocci décolorantes, subfusci, rami versus apicem cjmosi 1. paniculati. Spora simplices.
Brownish Moulds, at first white, irregularly branched, with the ramuli mostly near the apex, and forming little
cymes or panicles, but not verticillate. (Name from ttoXvs, many, aud a x n ç , a ray)
1. P o ly a c tis v u lg a r is (Lk. Obs. i. p. 14. f. 22).
H.\b. On dead twigs. Archer.
The few perfect individuals that I have seen axe but slightly divided above, but the plaut seems a mere form
of the common P. vulgaris. The spores are slightly obovate, and about -sggg
Geu. LX II. EH IX O m iC H UM , Corda.
Flocci sursum incrassati, spiculiferi, spiculis sporiferis. Spora subglobosæ.
Distinguished from Botrytis by the swollen tips of the threads, which are studded with the spores. (Name
from pwTj, a file.)
I. RMnotrichum microsporum (Berk.); filis agglutinatis, clavulas subcylindricas efformantibus,
apicibus cylindrico-clavatis, sporis globosis minutis.
Hab. On soil. Archer.
IVhite. Mycelium at first creeping, then a^lutinated into httle fascicles, so as to fonn short Isariæform clubs,
but frequently barren ; ultimate flocci cylindrico-clavate, obtuse, studded with very minute spicules, each of which
bears a globose spore inch in diameter.—This has the habit of an Isaria, and is moreover distiuguished by its
minute spores.
Gen. LX III. MOECHELLA, B ill.
Receptaculum clavatum 1. pileatum. Hymenium costis elevatis lacunosum. Asci fixi.
Morels occur in many parts of the world, and the common species is collected in the northern Himalayas, for
food, as it is in Europe. I have seen but a single immature Tasmanian specimen. (Name Latinized from the
German, Morchel)
1. MorcRella escu len ta , S conica (Fr. Syst. Myc. ii. p. 7).
Hab. On the ground. Archer.
Gen. LXIV. HELA^ELLA, L.
Receptaculum pileatum, centro suffultum, defiexum. Hymenium læve, superum. Asci fixi.
Distinguished at once from Morels by their lobed, even receptacle. Some of the species are esculent, as is
probably the I (Name applied to some Fungus or esculent vegetable by Cicero.)
1. H e lv e lla monachella (Fr. Syst. Myc. ii. p. 18).
H a b . In the valley on the north side of Cuming’s Head, about halfway up, Nov. 1855, Archer.
This is rather larger than the European form, but differs in no other respect. The pileus is dark-brown, lobed,
deflexed, and adnate; the stem pale rufous, and smooth.
Gen. LXV. LEOTIA, Hill.
Receptaculum pileatum, orbiculare, margine revolutum, supra margineque fructiferum. Hymenium
læve. Asci fixi.
The smooth, orbicular, revolute head, with its tumid margin, characterizes this genus. The typical species
has au extremely wide range. (Name probably from Xetos, smooth)
1. L eo tia lubrica (Pers. Syn. p. 613).
Hab. On the ground, Archer.

Carnoso-mollis, capitatus. Receptaculum clavatum, infiatum, a stipite discretum. Asci fixi.— Fungi

Distinguished principally from Geoglossum by their brighter colours and different habit. (Name, a diminution
of Mitra)
1. M itn ü a vino sa (Berk.) ¡ vinoso-puipurea, graoüis, lineari-ckvata, sporidiis lineari-oblongis mi-
nutis curvis.
Hab. On dead wood. Archer.
About 2 inches high, of a vinous-purple. Stem filiform, smooth, swelling above into a cylindrical head. Sporidia
linear-oblong, curved, inch long.— Closely allied to Mitrula Berterii, M., which is of a deep-brown tint,
and has the sporidia scarcely curved.
Gen. LX V II. GEOGLOSSUM, Pers.
Carnosum. Receptaculum simplex, clavteforme, stipitatum. Hymenium clavam ambiens. Asci
elongati.— Fungi saturate colorati.
The more tjqucal species are very distinct from Mitrula; others are almost confluent with that genus. The
only Tasmauian species belongs to a Eui'opean tj-pe, and is very widely diffused. (Name from yg, the earth, and
yX<u<rcra, a tongue.)
1. Geoglossum glabrum (Pers. Syn. p. 488).

Receptaculum carnosum vel subcarnosum, marginatum, cupuleeforme, primo clausum, subtus sterile.
Asci fixi.
This large genus is amply represeuted in Tasmauia, and under a great variety of forms, which belong, however,
to Eui'opcau tjqDes. (Name from Pezica, a term used by Pliny for stemless Fimgi.)
1. P e z iza aurantia (Pers. Obs. ii. p. 76).
