AUSTRALIAN FUNGI, NEW OR UNRECORDED. 



DECADES I.-II. 



By D. McAlpine, Corresponding Member. 



Although a considerable amount of attention has been given 

 to the Fungus-flora of Australia, a large number of species still 

 remain to be described, at least among the micro-fungi. 



These are either new to science or have not hitherto been 

 recorded for Australia, and since numbers of such are continually- 

 coming under my notice, it is desirable to render the descriptions 

 available for other workers. 



The introduction and cultivation of economic plants is no 

 doubt responsible for many of these, but the native vegetation is 

 likewise rich in new forms, and it will be my aim to record the 

 indigenous species as well as those which are already known. In 

 these two decades eleven new species and twelve different genera 

 are represented. 



1. AnTHOSTOMELLA DANTHONIiE, n.Sp. 



Minute, black, gregarious pustules on leaves and leaf-sheaths. 

 Perithecia covered, densely crowded and running in lines, opening 

 at surface by pore, surrounded by pale ruddy tissue, and occupy- 

 ing entire depth of leaf, always much compressed. Asci cylindrical 

 or bulging, slightly pointed and rounded at apex, tapering into 

 short stalk at base, 8-spored, 140-150 x 19-20 /u, but may reach a 

 breadth of 28 [x when sporidia are partially two-rowed. Sporidia 

 monostichous, occasionally distichous, dirty brown, very thick- 

 walled, elliptical, 20-26 x 15-17 n; paraphyses hyaline individually 

 but pink in the mass, longer than asci, very slender (0-5-1 /u) with 

 highly refractive granular contents.
