The Teloschistales are an order of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. According to one 2008 estimate, the order contains 5 families, 66 genera, and 1954 species. The predominant photobiont partners for the Teloschistales are green algae from the genera Trebouxia and Asterochloris.

The Arthoniales is the second largest order of mainly crustose lichens, but fruticose lichens are present as well. The order contains around 1500 species, while the largest order with lichenized fungi, the Lecanorales, contains more than 14000 species.

The Pertusariales are an order of fungi in the class Lecanoromycetes, comprising 8 families, 31 genera, and over 600 species, many of which form lichens. This diverse group is characterized by complex taxonomic history and ongoing phylogenetic revisions. Originally proposed by Maurice Choisy in 1949 and later formally published by the lichenologists David L. Hawksworth and Ove Eriksson in 1986, Pertusariales has undergone significant reclassification due to molecular phylogenetics studies. The order includes well-known genera such as Pertusaria and Ochrolechia, as well as families like

Verrucariales is an order of ascomycetous fungi within the subclass Chaetothyriomycetidae of the class Eurotiomycetes. Although most of the Verrucariales are lichenised, the family Sarcopyreniaceae consists of 11 species of lichenicolous (lichen-dwelling) fungi. Phylogenomic analysis suggests that the divergence between the lichenised Verrucariales and nonlichenised Chaetothyriales occurred about 131 million years ago.

Rytidosperma tenuius, or purplish wallaby grass, is an Australian species of wallaby grass found in south eastern Australia, usually on clay or sandy soils in the drier eucalyptus woodlands. The grass is perennial, and it may grow up to 1.2 m tall. It is native to the Australian states of Queensland, New South Wales, Victoria, South Australia and Tasmania, and it has been introduced to New Zealand. The inflorescences have a characteristic reddish colouration, and the attractive purplish bracts of young flowers can also aid in identification. The specific epithet tenuius is derived from the
