except towards the base, where it is at times clothed with, cottony filaments wliich spread over the soil.

This fungus originates beneath the cuticle, in slender dull black parallel fines ; it afterwards forces itself through
to tbe surface and resembles some Puccinia. No characters exist to distinguish it as a species, tbough its habit is
very peculiar.

H a b . Lord Auckland’s group and Campbell’s Island ; on the withered stems of Clirysobactron Rossii
of tbe previous year’s growth.
Pei'ithecia parva, epidermide tecta, subprominula, atra, globosa. Spora pellucidæ, irregulares v. lanceolatæ,
utrinque acutæ, triseptatæ, quandoque breviter pedicellatæ ; endoebromio cellulis conformi.
There are no external characters by which this may be d^criminated from several other black punctiform Pu/ujl.
The structure of the spores indicates a total want of affinity with Sphæi'ia ; these, under a low power, appear multi-
septate or triguttate ; but, with a liigher lens and well adjusted light, each is seen to be furnished with three transparent
septa : their shape is that of Neottmpora.

External appearance very closely resembling the Coeorna Luzula, Libert., but the form of the spores is quite
different, and also like Uredo oblongata, which likewise grows upon Luzula, but is a very different parasite.

H ab. Lord Auckland’s group and Campbell’s Island ; on th e scapes of Chrysobactron Rossii witli Hen-
Fries says of this plant, or rather of what have heen referred to it, “ Farrago spcciernm minimarum” and un der
it two very different productions are given in the ‘ Scleromycetes Suecicse,’ (no, 38). Oi one of these, hoth a
larger and smaUer fonn occm-; the other is identical with what has been piibUshed as a smaU state of Splmria com-
plmiata. 1 have given, at nos. 267 and 288, of my British ‘ Fungi’ (Fasc. 4th), the latter as Fries’s var. minor of
Sp. lierhanm and Sp. complamta intending to fflustrate his views, and with no idea that it would prove identical
vrith any of the lai-ger or normal species, which are well distinguished by theh- sporidia. These, in the true 8. her-
barmn, are oblong, with several longitudinal and transverse dissepiments, like what are seen in Splueria labumi, in
the specimens before me from Auckland Island and in the Im-ger English form. The plant published in my ‘ Fasciculi’
is destitute ot asci, wHch is the case with 8. acuta, Hoffm. The analysis ot the latter plant as given by GrevUle,
belongs to S. coniformis which often occm-s on the same stem. I t is not properly a Sphmia but either a Splmronema
or a Septoria, as extended hy Desmazibres, or finaUy, if Sphceria he remodeUed according to the plan upon which De
Notaris has revised the Italian species, it wiE come under some new generic name.
On carefuUy removing the cuticle of the Chrysobactron, I find that in the specimens before me the perithecia
give out a few stout filaments which creep for a short distance; this I beUeve to be a common oocun-ence with
the suhcuticular species. On the same stalks, individuals having the same external characters oceiu-, in which the
sporidia are imiseptate. This form I ot first believed to be a distinct species, but am now satisfied tliat it is an
imperfect state of S. herharnni; especiaUy since thi-ee septa are sometimes visible.

I know' of no species at aU resembling the present. Tlie change in the fonn of the asci and sporidia is very
instnictive and confirms me in my opinion, that Splueria herbarmu and its accompanj'ing imiseptate state belong to
the same species (vid. supra). It is worthy of observation, that the sporidia exMhit these changes whilst stiU
colom-loss. Septa are how'evor sometimes formed as in the genus Fiplcdia after the spores have acquued their
colom-.
