Phylogeny, morphology and culture growth for two novel fungal species from resin-covered branches of Araucaria araucana in Chile

The datasets included in this article compile those used for the description of two new species of fungi found in Araucaria araucana in Chile. Both species isolated from resin covered branches of these trees in their natural range. Items include a list of isolates, with their original codes, location of isolation and preliminary grouping (putative species 1 or 2). Phylogenetic analyses, done for seven different gene regions, concatenated for the ITS, LSU and SSU and individually arranged, including also the RPB2, MCM7, TEF1 gene regions. A list of the taxa utilized for this purpose is included with their accesion numbers. Additionally, the results of morphological studies are included: morphological and anatomical analyses of sexual fruiting structures on branch samples, including a table for the comparison of the measured features with those of potentially closely related taxa. Lastly, the results for the study of the morphology and growth rate at different temperatures of fungal colonies for two groups of isolates (putative species) are included.

The results included in these files constitute strong evidence that the fungi found on Araucaria araucana in Chile represent two new species of fungi, belonging to the recently described subclass Cryptocaliciomycetidae, and potentially to the family Cryptocaliciaceae. However, the morphology of its sexual stage is more similar to that of Resinogalea humboldtensis, a fungus described without sequence data, and located in an unresolved family within the Ascomycota, the Bruceomycetaceae. Datasets support that our fungi and R. humboldtensis are closely related and should probably reside in the same genus, and therefore under the same higher taxa.
