Sporoschisma spp.Type: UG-1002

Category: Fungi

Taxonomical identification: Sporoschisma spp.

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: Goh, T.K., Ho, W.H., Hyde, K.D. and Umali, T.E. (1997) New records and species of Sporoschisma and Sporoschismopsis from submerged wood in the tropics. Mycological research 101, 1295–1307

Description: Conidia cylindrical with flattened ends, unequally and subsymmetrically 4- or 6-celled, 50–61×12–14 μm, smooth, thick-walled, slightly constricted at the septa; Central cells pale to dark brown, almost of equal size; End cells paler, short, discoid or somewhat truncate, flattened or slightly rounded at free ends (often absent). Cells light brown 4- or 6-celled, smooth, thick-walled. These conidia probably belong to Sporoschisma saccardoi. Specimens of which the end cells are missing, are possibly fragmented conidia of the same species (due to decay) or 3-septate conidia of other Sporoschisma species (e.g., S. juvenile Boud., S. mirabile Berk. & Broome).

(Sub-) Fossil occurence: No information

Co-occurence: No information

Modern occurence: Sporoschisma saccardoi is distributed in tropical (e.g., Indonesia, Taiwan, Ecuador, and South Africa) and more temperate regions (e.g., Europe). It is mainly found on submerged wood in freshwater habitats (Goh et al., 1997).

Palaeoenvironmental indication: No information
