Rogers, R.W. 1982: The nomenclature of some Australian lichens described as Lecanora and Placodium by Müller-Argoviensis. - Muelleria 5(1): 31-34. [RLL Suppl. Rec.# 971]
Keywords: LECANORA/ PLACODIUM
Abstract: J. Müller (Müll.Arg.) described a large number of lichens from Australia. When examining specimens in his herbarium it became apparent that some of the material he described as Lecanora and Placodium was in need of revision. Placodium flavostramineum Müll.Arg. is reduced to synonymy with Dirinaria applanata (Fée) Awasthi. Lecanora connivens Müll.Arg. and L. subimmersa Müll.Arg. (non Vainio) are reduced to synonymy with L. atra (Huds.) Ach. while the varieties L. atra var. serialis Müll.Arg. and L. atra var. virens Müll.Arg. are considered unworthy of formal taxonomic recognition. The new combinations Canderaliella xanthostigmoides (Müll.Arg.) R.W.Rogers, Lecidea glaucoflavens (Müll.Arg.) R.W.Rogers, L. hyalinescens (Müll.Arg.) R.W.Rogers, Ochrolechia macrosperma (Müll.Arg.) R.W.Rogers, Cladonia glaucolivida (Müll.Arg.) R.W.Rogers, and Xylographa permunuta (Müll.Arg.) R.W.Rogers are made. Lecanora albellaria Müll.Arg. and L. glebularis (Müll.Arg.) Zahlbr. are presented as correct names for two common Australian taxa.
