Campbelts Islands. .] FLORA ANTARCTICA. 171 



Fries says of this plant, or rather of what have been referred to it, " Farrago specierum mhiimarum" and un- 

 der it two very different productions are given in the ' Scleromycetes Suecicae,' (no. 38). Of one of these, both a 

 larger and smaller form occur ; the other is identical with what has been published as a small state of Spkana com- 

 planata. I have given, at nos. 267 and 288, of my British 'Fungi' (Fasc. 4th), the latter as Fries' s var. minor of 

 Sp. herbanim and Sp. eomplttnata intending to illustrate his views, and with no idea that it would prove identical 

 with any of the larger or normal species, which are well distinguished by then- sporidia. These, in the true S. her- 

 barum, are oblong, with several longitudinal and transverse dissepiments, like what are seen in Sp/iaria Lab/trni, in 

 the specimens before me from Auckland Island and in the larger English form. The plant published in my ' Fasciculi' 

 is destitute of asci, which is the case with S. acuta, Iloffni. The analysis of the latter plant as given by Greville, 

 belongs to S. coniformis which often occurs on the same stem. It is not properly a Sp/iaria but either a Spheeronema 

 or a Septoria, as extended by Desinazieres, or finally, if Splimria be remodelled according to the plan upon which De 

 Notaris has revised the Italian species, it will come under some new generic name. 



On carefully removing the cuticle of the Clirysobactron, I find that in the snecimens before me the nerithera'a

I know of no species at all resembling the present. The change in the form of the asci and sporidia is very 

 instructive and confirms me in my opinion, that Sp/iaria Iterbarum and its accompanying uniseptate state belong to 

 the same species (vid. supra). It is worthy of observation, that the sporidia exhibit these changes whilst still 

 colourless. Septa are however sometimes formed as in the genus Diplodia after the spores have acquired their 

 colour.
