Araucaria araucana is an ancient conifer, native to the mountain ranges in Chile and Argentina. These trees host a large number of organisms, mainly insects, strongly or even exclusively associated with them. The recent emergence of a novel canker disease on A. araucana has emphasised the importance of fungi associated with these iconic trees and has resulted in the discovery of various new species. In this study, we considered the identity of an unknown calicioid fungus consistently found on resin on the branches of A. araucana. Preliminary phylogenetic analyses placed isolates in the recently described sub-class Cryptocaliciomycetidae, closest to Cryptocalicium blascoi. However, the morphology of the ascomata and its occurrence in a unique niche suggested that the closest relative could be Resinogalea humboldtensis (Bruceomycetaceae, incertae sedis), a fungus with similar sporing structures found on resin of Araucaria humboldtensis in New Caledonia. There are no living cultures or sequence data available for either R. humboldtensis or its supposed closest relative, Bruceomyces castoris, precluding sequence-based comparisons. Morphological comparisons of the sporing structures on A. araucana confirmed that the ascomatal morphology of our unknown calicioid fungus and R. humboldtensis are almost identical and resemble each other more so than B. castoris or Cr. blascoi. A phylogenetic analysis based on the small subunit (SSU), internal transcribed spacer (ITS) and large subunit (LSU) rDNA regions resolved our strains into two clades with Cr. blascoi as its closest relative. Further analyses applying the Genealogical Concordance Phylogenetic Species Recognition (GCPSR) based on ITS, mini chromosome maintenance protein complex (MCM7), RNA polymerase II second largest subunit (RPB2) and translation elongation factor 1-alpha (TEF) gene regions, confirmed that strains represent two new species. Based on our morphological observations and phylogenetic analyses, we introduce two new Resinogalea species, R. araucana and R. tapulicola, and reclassify the genus in the subclass Cryptocaliciomycetidae.

Trade in services has grown more rapidly than trade in manufactured goods in recent decades. Countries from the Global South are chiefly responsible for this shift. The research note draws attention to service investment that originates in Southern economies and is directed at markets of the same (sub)continent. Such dynamics have been neglected by academic debates focussed on global value chains and offshored, largely generic services. The authors argue that direct integration into global markets is often disadvantageous for firms from the South, as they tend to play a subordinate role, face the risk of disinvestment and hardly upgrade. Regional markets offer better opportunities. These ideas are applied to Argentina and South Africa. The fDi Markets database and qualitative information from secondary sources are used to get a better grasp of the expansion of Argentinean and South African providers of advanced services into Latin America and sub-Saharan Africa, respectively. It is shown that regional markets matter. It appears that they allow companies from Argentina and South Africa to be lead firms, internationalize their business activities and achieve various forms of upgrading. [ABSTRACT FROM AUTHOR]
