Abstract:
Studies of Trochila (Leotiomycetes, Helotiales, Cenangiaceae) are scarce. Here, we describe two new species based on molecular phylogenetic data and morphology. Trochila bostonensis was collected at the Boston Harbor Islands National Recreation Area, Massachusetts. It was found on the stem of Asclepias syriaca , representing the first report of any Trochila species from a plant host in the family Apocynaceae. Trochila urediniophila is associated with the uredinia of the rust fungus Cerotelium fici . It was discovered during a survey for rust hyperparasites conducted at the Arthur Fungarium, in a single sample from 1912 collected in Trinidad. Macro- and micromorphological descriptions, illustrations, and molecular phylogenetic analyses are presented. The two new species are placed in Trochila with high support in both our six-locus (SSU, ITS, LSU, rpb1 , rpb2 , tef1 ) and two-locus (ITS, LSU) phylogenetic reconstructions. In addition, two species are combined in Trochila : Trochila colensoi (formerly placed in Pseudopeziza ) and T. xishuangbanna (originally described as the only species in Calycellinopsis ). This study reveals new host plant families, a new ecological strategy, and a new country record for the genus Trochila . Finally, our work emphasizes the importance of specimens deposited in biological collections such as fungaria.
