On rotten wood, accompanying Merulius lacrymans. aA 
Forming olive patches, about an inch broad. Flocci of two 
kinds; some irregularly branched, forked or trifid, often 
paler, irregular, and ending in two or three little tubercles, 
others finer, sparingly branched, sometimes septate, giving € off 
short erect threads, which bear the spores. Spores compo 
consisting of a number of globose slightly-scabrous lobes 
In an early stage of growth, they consist of a single row of 
cells, which gradually becomes double; ultimately, the. cells 
swell out and become globose. It does not appear that the 
lobes separate, as the old decayed spores are to be found 
amongst the flocci. 
The habit of this plant is exactly that of Helico snm 
vegetum. 
Tab. II. f. 9. Mystrosporium pulchrum, magnified ; a. spores 
highly magnified. 
Amongst the spores of the plant occur others, predi 
like those of Helicoma, Corda, but without any flocci belong- 
ing to them. Itis possible that they are more nearly of tht 
nature of Helicosporium, and are parasitic on the threads 
of the Mystrosporium. J have not, however, sufficient data to 
determine this point. 
* Fusarium lateritium, Nees.—Drumm. n. 192. (in part 
* Antennaria scoriadea, Berk. in Bot. of Ant. Voy. in 
Drumm. n. 192 (in part). 
On branches of shrubs, with F. lateritium. 
A description of this will shortly be given from good § 
cimens, in the Botany of the Antarctic Voyage. he Swan 
River specimens are very imperfect.
