58 CRYPTOGAMIA ANTARCTICA, [Auckland and 
gathered, belongs to the species quoted above. The stem is either equal or attenuated upwards, generally smooth, 
except towards the base, where it is at times clothed with cottony filaments which spread over the soil. 
2, CLADOSPORIUM, Link. 
1. CLADOSPORIUM herbarum, Link, Obs. ll. p. 37. 
Has. Lord Auckland’s group and Campbell’s Island; on the leaves of Carex appressa, Br. 
This fungus originates beneath the cuticle, in slender dull black parallel lines ; it afterwards forces itself through 
to the surface and resembles some Puccinia. No characters exist to distinguish it as a species, though its habit is 
very peculiar. 
3. HENDERSONIA, Berk. 
1. HENDERSONIA microsticta, Berk.; peritheciis sparsis punctiformibus atris globosis minutis, sporis 
lanceolatis acutis triseptatis. (Tas. LXVIII. Fig. I.) 
Has. Lord Auckland's group and Campbell’s Island; on the withered stems of Chrysobactron Rossi 
of the previous year’s growth. 
Perithecia parva, epidermide tecta, subprominula, atra, globosa. Spore pellucide, irregulares v. lanceolate, 
utrinque acute, triseptate, quandoque breviter pedicellate ; endochromio cellulis conformi. 
There are no external characters by which this may be. discriminated from several other black punctiform Fungi. 
The structure of the spores indicates a total want of affinity with Spheria; these, under a low power, appear multi- 
septate or triguttate; but, with a higher lens and well adjusted light, each is seen to be furnished with three trans- 
parent septa: their shape is that of Neottiospora.

4. UREDO, Pers. 
1. Urzo antarctica, Berk. ; amphigena, maculis oppositis purpureis, soris bullatis, sporis majusculis 
levibus late obovatis fuscis. (Tas. LXVIII. Fig. IL) 
Has. Campbell’s Island; on leaves of Luzula erinita. 
Amphigena; maculis parvis, oppositis, subrotundatis, purpureis, subtus pallidioribus. Sori bullati. Spore 
obsoletissimz, pedicellatee, obovate v. subglobosiz, leves, guttula centrali oleosa preediti. 
External appearance very closely resembling the Cæoma Luzule, Libert., but the form of the spores is quite 
different, and also like Uredo oblongata, which likewise grows upon Luzule, but is a very different parasite.

very highly magnified. l 
5. SPHARIA, Hall. 
1. Spmzrıa herbarum, Pers. Synops. p. 19. (quoad var. y, tectam), Fr. Syst. Myc. vol. ii. p. 511. Notaris 
in Act. Acad. Turin. vol. vii. p. 30. cum analysi optima. (Tas. LXVIII. Fig. III.) 
Has. Lord Auckland’s group and Campbell’s Island ; on the scapes of Chrysobactron Rossii with Hen- 
dersonia microsticta.
