Myelorrhiza, a new Australian Lichen genus from North Queensland.

Abstract

The new lichen genus Myelorrhiza has been described to accommodate two new species from north Queensland: Myelorrhiza antrea Verdon & Elix, the type species of the genus, growing on walls of caves or cave-like cavities on Bishop Peak in the Cardwell Range, and Myelorrhiza jenjiana Verdon & Elix, growing on rainforest trees in the Windsor Tableland, Walter Hill Range and Lannercost State Forest. Myelorrhiza has stipitate apothecia and some affinity with the genus Gymnoderma of the Cladoniaceae.
