Rust HUBB: DNA barcode-based identification of Pucciniales.

Rust fungi (Pucciniales, Basidiomycota) are a species-rich (ca. 8000 species), globally distributed order of obligate plant pathogens. Rust species are host-specific, and as a group they cause disease on many of our most economically and/or ecologically significant plants.

Insects and their Laboulbeniales (Ascomycota, Fungi) of Lake Eustis and Emeralda Marsh Conservation Area: A case study on urbanization and diversity.

A rapid biodiversity assessment of insects and associated Laboulbeniales fungi was conducted over the course of five nights in August, 2018, at two central Florida lakes: Lake Eustis and the nearby protected and restored National Natural Landmark, Emeralda Marsh Conservation Area (EMCA), which encompasses a portion of Lake Griffin. Lake Eustis was surveyed for Laboulbeniales in 1897 by mycologist Dr. Roland Thaxter but has not since been investigated.

New species of (Laboulbeniales, Ascomycota) on Heteroptera (Hemiptera, Insecta) from South America.

Four new species of are described, adding substantially to the known species recorded from Heteroptera hosts. Previously, only 12 species of and only 96 of the approximate 2325 known species of Laboulbeniales have been recorded on the Heteroptera. The addition of these four new species of , occurring on two genera within Veliidae, brings the total number to 100 species.

New species of Laboulbenia (Laboulbeniales, Ascomycota) on Gerridae (Hemiptera, Insecta), a new host family.

Four new species of (Laboulbeniales, Ascomycota) occurring on Gerridae (Hemiptera, Insecta), a new host family, are described from six Central and South American countries: Bolivia, Brazil, Ecuador, Panama, Peru, and Venezuela. The new species are , and .

New species of Prolixandromyces (Laboulbeniales) from South America.

Four new species of Prolixandromyces (Laboulbeniales, Ascomycota) found on Veliidae (Heteroptera) from Bolivia, Brazil, Peru, and Venezuela are described and illustrated. These four species, Prolixandromyces anseris, P. tritici, P.
