Our goals were to explore the relationship between biogeography and the evolution of fire-adaptive syndromes in the genus Pinus. We used a previously published time-calibrated phylogeny and conducted ancestral trait reconstruction to estimate the likely timing of diversification in Pinus, and to determine when fire-adaptive syndromes evolved in the lineage. To explore trait conservation among fire syndromes and to investigate historical biogeography, we constructed ancestral state reconstructions using the program RASP and estimated the degree of conservatism for fire-adapted traits in the program BaTS. Our reconstructions suggest that the Bering land bridge, which connected North America and Asia, probably played …

Hebeloma ifeleletorum is described as a new species from American Samoa. Based on analyses of ITS and combined nLSU-ITS datasets H. ifeleletorum clusters with but is distinct from described species that have been placed in the genus Anamika by some. The phylogenetic relationship of H. ifeleletorum to the genus Anamika from Asia and to other species from Australia and New Caledonia suggests that H. ifeleletorum has origins in the western Pacific.
