Abstract:
Three species of fossil epiphyllous coelomycetes are described from Dominican and Mexican amber in the new genera, Asteromites gen. nov., Leptostromites gen. nov. and Leptothyrites gen. nov. Characters of the pycnidia and spores most closely resemble members of their extant respective genera, Leptostroma, Asteromella, and Leptothyrium, respectively. A. mexicanus sp. nov. occurs on a petal (possibly from a caesalpinoid legume such as Peltogyne) in Mexican amber. Leptostromites ellipticus sp. nov. occurs on a dicot leaf in Dominican amber, and Leptothyrites dominicanus sp. nov. on a monocot (grass?) leaf in Dominican amber.
