A contribution to an inventory of lichens from South Sister, northeastern Tasmania

A lichen survey at South Sister, northeastern Tasmania, has yielded 234 taxa. The following 16 are recorded from Tasmania for the first time: Acarospora veronensis A. Massal., Arthothelium macounii (G. Merr.) WJ. Noble, Austrolecia antarctica Hertel, Bacidia wellingtonii (Stirt.) D.J. Galloway, Buellia griseovirens (Turner & Borrer ex Sm.) Almb., Coccocarpia pellita (Ach.) Mull. Arg., Hafellia subcrassata Pusswald, H xanthonica Elix, Hypocenomyce scalaris (Ach.) M. Choisy, Illosporium carneum Fr., Lecidella pruinosula (Mull. Arg.) Kantvilas & Elix comb. nov., Lecidella sublapicida (Knight) Hertel, Lepraria eburnea J .R. Laundon, Micarea denigrata (Fr.) Hedl., Mycoblastus campbellianus (Nyl.) Zahlbr. and Mycoporum antecellens (Nyl.) R.C. Harris. The survey represents the first of its kind for any dolerite peak in Tasmania, and serves as a benchmark for future studies. Aspects of the distribution and ecology of the flora, the occurrence of rare, threatened or otherwise unusual species, and significant range extensions are discussed. The effect of metal-rich run-off from galvanised structures is identified as a potential threat to the flora values of the site.
