NAME Reduviasporonites catenarius
AGE Late Devonian (Late? Frasnian).   AGE span: 385.3...374.5 mya
K&J CLASSIFICATION (2000) Fungi imperfecti, Phragmosporae.

FIGURE REFERENCE
SPECIES, AUTHORITY R. catenarius (Playford) Kalgutkar & Jansonius 2000
LOCATION Carnarvon Basin, Western Australia.
ORIG DESCRIPTION* Compound palynomorph structures consisting of two to ten spherical bodies or vesicles linked uniserially. Individual vesicles average 12 µm in diameter (subequal within a given series); outline subcircular (shape originally ± spherical); wall 0.3 - 0.5 µm thick, psilate to faintly scabrate, usually displaying conspicuous and irregular (marginal to transverse) compression folds. Amount of overlap of one vesicle with its neighbour is variable: 1.5 - 5.0 µm. No definite excystment opening observed, though vesicle walls often show irregular fissuring. Vesicle diameter 9 (12) 17 µm. Length of holotype, with five vesicles, 50 µm.
COMMENTS* Dissociated vesicles not uncommon, but the uniserial arrangement is believed to be a fundamental feature of this species, which could well represent a fungal multicellular structure.

K&J REMARKS Kalgutkar and Jansonius (2000) became aware of this species only after the plates were formalized, making it not possible to illustrate it. However, the specimens illustrated by Playford appear to be virtually identical to R. catenulatus Wilson. Playford did not compare with Wilson's species, but assigned his species to Synsphaeridium Eisenack 1965, a genus of spheroidal leiospheres closely associated to form more or less planar aggregations ("linear arrangements were not excluded").
