Type: UG-1157
Category: Fungi
Taxonomical identification: Rosellinia sp.
First publication: Gelorini, V., Verbeken, A., van Geel, B., Cocqyt, C. and Vershuren, D. (2011) Modern non-pollen palynomorphs from East African lake sediments. Review of Palaeobotany and Palynology 164, 143–173
Other publication/s: Petrini, L.E. (1993) Rosellinia species of the temperate zones. Sydowia 44, 169–281
Description: Ascospores ellipsoid to fusiform, inequilaterally one-celled, brown to dark brown, 25 × 6 μm, smooth, thick-walled and with tapering ends; germ slit sigmoid and running about 3/4 of the spore-length. This morphotype resembles Rosellinia dingleyae L.E. Petrini, a new Rosellinia species encountered in New Zealand (Petrini, 2003), but the East African ascospores are slightly smaller and may thus represent an unknown tropical Rosellinia species.
(Sub-) Fossil occurence: No information
Co-occurence: No information
Modern occurence: Rosellinia is widespread in temperate and tropical regions, and commonly found on decaying herbaceous stems andwood. In the tropics some species (such as Rosellinia necatrix Berl. Ex Prill.) are particularly known as root pathogens, exclusively in plantations of cultivated trees and shrubs (Petrini, 1993).
Palaeoenvironmental indication: No information
