“…Licea succulenticola was described as new to science by Mosquera et al (2003) based on material collected on the Canary Islands. It has since been reported from a number of other desert localities where it is often abundant, including Mexico (Estarda-Toress et al 2009), Argentina (Lado et al 2011) and Peru (Lado et al 2019). Although the most common substrates for this species are dead portions of succulent plants, it also occurs on bark, as was the case for the first report from mainland Africa (Stephenson et al 2019).…”

“…Didymium iridis, like the preceding species, has been reported from surveys of deserts (e.g. Estrada-Torres et al 2009;Wrigley de Basanta et al 2013;Stephenson et al 2019) but most of the substrates on which it occurred were derived from non-succulent plants. The species has been reported from a range of habitats in Australia (White et al 2020;Stephenson 2021).…”

“…However, a number of other species (e.g. Estrada-Torres et al 2009;Lado et al 2009Lado et al , 2013Lado et al , 2019 have been described since then. Some of these succulenticolous myxomycetes are not yet known from any other substrate.…”

Context Cacti are endemic to North and South America, but numerous species have been spread all over the world after Europeans visited the Americas. Their global spread has impacted various aspects of terrestrial ecosystems, including the distributions of succulenticolous myxomycetes. Aims In this study, we examine the association of myxomycetes (also known as plasmodial slime moulds or myxogastrids) with three introduced species of cacti in Australia. Methods Using the moist chamber culturing technique we prepared 33 cultures from dead portions of three species of cacti collected in New South Wales and Queensland. Key results Eighty-eight percent of moist chamber cultures yielded evidence of myxomycetes (either plasmodia or fruiting bodies). A total of 12 species representing six genera were recorded. Physarum compressum was the most abundant species (appearing in 20 of the 33 cultures), with species such as Perichaena depressa also relatively common. We also report the first records of Perichaena luteola in Australia. Conclusions This is the first study to investigate the assemblages of myxomycetes associated with members of the Cactaceae in Australia, and we highlight the occurrence of succulenticolous myxomycetes on the continent. Implications This study leads to a better understanding of the biogeography, distribution and ecology of succulenticolous myxomycetes. We also add a new species record for Australia.
