New species of Septobasidium from southern Costa Rica and the southeastern United States

New species are described in Septobasidium, a genus of urediniomycete parasites on scale insects. One new species, S. gomezii, is described from Costa Rica, and another, S. meredithiae, is described from Louisiana. S. gomezii is most similar to S. septobasidioides, but macroscopic and microscopic differences support it being a distinct species. S. meredithiae is similar to S. alni and S. castaneum but differs from these species in several macroscopic and microscopic characters, especially when the species are observed on the same host tree and insect species. Another species collected only once in Costa Rica is listed with observations but it is not formally described here. This Septobasidium species shares some key characteristics with S. ramorum but combines a dense, compact, nearly black thallus and pigmented probasidia-like structures with spindle-shaped haustoria. Implications for taxonomy, morphological evolution and host specificity in Septobasidium are discussed.     

Molecular phylogeny suggests a single origin of insect symbiosis in the Pucciniomycetes with support for some relationships within the genus Septobasidium

In the Pucciniomycetes, a class of fungi that includes the plant pathogenic rust fungi, insect parasitism is restricted to a single family, the Septobasidiaceae. The Septobasidiaceae form a variety of symbioses with scale insects and have remained largely unstudied since the 1930s. Transitions between plant and animal parasitism and between mutualism and parasitism cannot be fully addressed in the Basidiomycota without a clear phylogenetic hypothesis for the Septobasidiales. Here, molecular phylogenetic methods were applied to understand the origin of scale insect parasitism, test the monophyly of the order Septobasidiales, and evaluate the infrageneric concepts in the largest genus of scale insect parasites, Septobasidium. DNA sequence data from rRNA genes were used to infer higher-level relationships within the Pucciniomycetes, and data from translation elongation factor 1-alpha (tef1) were added for phylogenetic inference within the Septobasidiaceae. Data from tef1 revealed different intron arrangements within Septobasidium, but the molecule did not provide much additional phylogenetically informative data. Likelihood-model-based phylogenetic analyses of 44 Pucciniomycotina taxa provided moderate support for a single origin of insect parasitism. Within the Septobasidiaceae, there was little or no support for a monophyletic Septobasidium, and well-resolved subclades of Septobasidium species contradict previous morphological delimitations of groups within the genus.     

Three new species of Sphaerosyllis (Polychaeta, Syllidae) from mangrove habitats in Belize

Notes on Neotropical Selaginella (Selaginellaceae), including new species from Panama

Three new species ofSelaginella from Panama are described and illustrated:S. correae, S. salazariae, andS. taylorii. In addition, a new name,S. smithiorum, is proposed forS. velutina A. R. Smith (nonS. velutina Cesati), and eleven new distribution records are reported. The relationships of the species are discussed and keys to some of the species are provided.

The Central AmericaS. apaloblastum andS. barnesii are new combinations.Sematophyllum galipense, S. amnigenum, andS. cochleatum are briefly discussed.

Genome stability: a new member of the RFC family

Three distinct forms of replication factor C are known to play vital roles in genome replication and integrity in eukaryotic cells. A fourth such complex has recently been identified; initial results suggest that this new family member plays an important role during S phase.
