Abstracts |
Aside from a variety of arthropod remains, Dominican amber also contains an assortment of leaves, flowers, and seeds. An orchid seed with a developing embryo in Dominican amber is described as Mycophoris elongatus gen. et sp. nov. Cells of the developing embryo were infected with a fungus that is described as Synaptomitus orchiphilus gen. et sp. nov. The fungus represents a Basidiomycota that was probably serving as an orchid mycorrhiza (OM), based on its morphology and the formation of pelotons inside infected embryo cells. The single piece of amber containing the fossil was obtained from a mine in the Dominican Republic and is at least 15–20 Ma. |
