A very curious genus, confiued to temperate regions, remarkable for its operculum and peculiar habit. (Name
from Kparqp, a yoblet.)
1. Crateritim minutum (Fr. Syst. Myc. iii. p, 151).
Hab. On grass, Archer.
G m. X LV III. STEMONITIS, Gled,
Pei'idium simplex, tenuissimum, membranaceum, fugax. CapUlitinm determiiiatum, stipiti intranti
adnatum. Flocd reticulati.
The genus Stemonitis is a columellate Physarum. Its species me mostly widely diffused, and some flouiish both
iu hot and temperate regions. One Tasmanian form is remarkable for its rough spores. (Name from rrrqfmv, a
thread or slem.)
1. S tem on itis fu sca (Roth, Germ. i. p. 448).
Hab. On dead wood, Gunn.
2. S tem o n itis oblonga (Fr. Syst. Myc. iii. p. 159).
Hab. On decayed wood, Archer.
8 . S tem on itis echinuluta (Berk.) ; peridio globoso columbino-clialybeo, stipite valido aterrimo
sursum attenuato semipenetrante, capülitio pallido globoso, sporis magnis eleganter echinulatis.
ILab. Ou moss. Archer.
Peridium globose, very tliin, showing dove-like prismatic hues, tliicker and persistent below. Stem longer than
the peridium, veiy dark, stout, attenuated upwards, passing halfway into the cavity of tlie peridium. Capillitium
compact, growing from the columella. Spores inch across, beautifully echinulate.—Allied to S. arcyrioides,
but remarkable for its stout stem and large spores.
Gen. XLIX. TRICHIA, Ball.
Feridinm simples. Columella nulla. Capillitium elasticum, floccis vascularibus.
The spiral threads distinguish this from aU Myxogaslres. The species are for the most part widely diffused,
but, besides common fonns, Tasmania has two very distinct species. (Name from dpi^, a hair.)
1. T rich ia rubiformis (Pers. Syn. p. 176).
Hab. On dead wood, Archer.
2. T r ich ia m e ta llic a (Berk.) ; peridio lentiformi fulvo metallicis coloribus ornato subtus umbiiicato,
stipite brevi cylindrico carneo, floccis rectis radiantibus sporisque incaruato-fulvis.
Hab. On dead wood, Archer.
Peridium lentiform, tawny, adorned with various metaUic tints, frequently disposed in little specks like granulations,
flattened or umbilicate beneath. Stem short, cylindrical, flesh-coloured. Flocci slender, radiating. Spores
inch across, reddish-ochre, like the flocci, inclining to tawny.—The most beautiful of aU tlie Trichia, though
small, and singularly distinct. Its nearest ally is Trichia fallax.
3. Trichia chrysosperma (DC. Fl. Fr. ii. 250).
Hab. On dead wood : Sassafras Valley, Archer, J. B. H.
The stem is sometimes far more distinct than usual.
4. T rich ia varia (Pers. Syn. p. 181).
Hab. On dead wood and moss, Archer.
5. T rich ia ver ru cosa (Berk.); subcæspitosa, peridio turbinato sordide ochraceo, stipite debili filiformi
decumbente sporis magnis verrucosis.
Hab. On charred wood, Archer.
Somewhat crowded or scattered. Peiidia dull-ochi-e, turbinate, seated on a filiform, weak, decumbent stem.
Spores globose, verrucose, incb across, yeUow, as well as the capülitium.—This species, which at first sight
resembles Trichia varia, is at once distinguished by its large verracose spores.
Gen. L. PERICHÆNA, Fr.
Peridium simplex, sæpe circumscissum. Flocd rari, sporis immixti.
This genus resembles Trichia, but is at once distinguished by the absence of vascular haks. (Name from
iTspi, around, and xatvoi, to gape)
1. Per ichæna contor ta (Pr. Syst. Myc. iii. p. 192).
H a b . On dead wood, rfrc/ier.
Paler than usual, and with no trace of capillitium.
Gen. L I. LICEA, Schrad.
Peridium tenue, irregulariter dehiscens. Spora laxæ. Flocd nulli.
Distinguished by the utter absence of flocci fi-om all Myxogaslres, except one or two of the more obscure Peri-
chance. The only Tasmanian species is a strictly European form. (Origin of name unknown.)
1. L ic ea fragiformis (Fr. Syst. Myc. iii. p. 196).
Hab. On dead wood : Penquite, Gunn.
Gen. L IL CYATHUS, Pers.
Peridium primum obovatum vel fusiforme, obtusum, apice demum centrali dehiscens, et velo candido
tympani instar clausum, e membranis tribus arete invicem applicatis composiium. Sporangia plana, umbi-
licata, funiculo parietibus addicta. Sporce sporophoro innatæ.
Of this ciu-ious genus there is but one Tasmanian speeies, identical with one of the two New Zealand forms,
and resembling the European C. vernicosus. (Name from cyathus, a cup.)
1. Cyathus C o len so i (Berk, in Fl. N. Zeal. p. 192).
Hab. On cowdung, etc., Gunn, Archer.
Gen. L II I. SPHÆROBOLUS, Tode.
Peridium duplex, interius demum elastice itiversuin et sporangium solitarium globosum ejiciens.
Spora sporophoro adnatæ.
Distinguished from Cyathus and its allied genera by the solitary sporangium which is shot out of the peridium.
by the inversion of the inner coat, like a shell out of a mortar. The structure of the sporangia is essentially tlie
same. (Name from o-<^aipa, a ball, and (¡uXKui, to cast)
1. Sphseroholus ste lla tu s (Tode, Meek. i. p. 43).
Hab. On decayed wood, Archer.
Gen. LIV. SPHÆRONEMA, Fr.
Periihedum liberatum vel omnino liberum. Spora demum exsudantes apicique perithecii adhærentes.
