“…is a genus of foliose to fruticose lichens that had long bewildered taxonomists owing to its lack of ascomata and highly variable morphology and chemistry. Advances in the knowledge of the group over the last 50 years have seen the clarification and description of new species, mainly from New Zealand and Tasmania (Galloway 1983; Kantvilas 1987, 1994, 1996, 1998), mainland Australia (Kantvilas 2004), South-East Asia (Obermayer & Kantvilas 2003; Kantvilas et al 2005), southern Africa (Mathey 1971; Kantvilas et al 2003) and South America (Kantvilas & Elix 2002; Marcano 2021 a , b ). The first investigations of the phylogenetic position of Siphula (Platt & Spatafora 2000; Stenroos et al 2002) placed it in the Icmadophilaceae .…”

The term ‘siphuloid’ is introduced for a suite of distinct lichen genera with a superficially similar foliose to fruticose morphology, notably Siphula, Siphulella, Siphulopsis, Parasiphula and Knightiellastrum. Three new species are described: Parasiphula squamosa Kantvilas (from Tasmania and New Zealand), characterized by a whitish grey, squamulose or minutely foliose thallus lacking lichen substances or containing traces of atranorin; Siphula capensis Kantvilas (from southern Africa), containing baeomycesic and squamatic acids, and characterized by robust, broadly flattened, rounded lobes with thickened apices; and S. crittendenii (from the Caribbean but with an outlying collection from Queensland, Australia), an epiphytic species containing thamnolic acid, with fragile, flattened lobes mostly to 10 mm long and 1−5 mm wide, with ragged or much-divided apices. Salient features of the species of Parasiphula are summarized and a first key for this genus is presented. Infrageneric problems in Siphula are also discussed briefly.

“…3B). Siphula torulosa is chemically identical but has more slender, erect or ascending lobes, 4-12 mm tall and 0.3-0.8 mm wide, that form relatively dense tufts or swards (see also Mathey 1974). Although many species of Siphula are very widespread geographically and very variable morphologically (see Kantvilas 2002), S. torulosa is a very welldefined, localised taxon.…”

Kantvilas, G. (2004). New Australian species in the lichen genus Siphula Fr. Austrobaileya 6 (4) 949-955. Two species of Siphula are described and illustrated: S. australiensis Kantvilas sp. nov. from the Central and Southern Tablelands of New South Wales, and S. parhamii Kantvilas sp. nov. from the humid wet tropics of Queensland. Their relationships with other taxa in the genus are discussed. An unusual, peltate form of Siphula coriacea Nyl. from Central Queensland is briefly noted and illustrated.

“…Approximately 25 species of Siphula have been described to date (Hawksworth et al 1983), with centres of diversity apparent in southern Africa (Mathey 1974), South America, Hawaii (Magnusson & Zahlbruckner 1945), and Tasmania and New Zealand (Galloway 1985;Kantvilas 1987 Lobafic acid (major) and conlobaric acid (trace).

Siphula elixii, a new lichen from Tasmania and New Zealand

Galloway (1992) records eight species from New Zealand, with five of these also present in Tasmania (Kantvilas 1989). However, there are several additional undetermined taxa in these regions, one of which is described below as new. AbstractThe new lichen, Siphula elixii Kantvilas, is described from Tasmania and New Zealand. It is related to S. fragilis (J.D. Hook. & Taylor) J. Murray but is characterised chiefly by the presence of lobaric acid, which is recorded from the genus Siphula for the first time.
