...C.B. FOSTER; M.H. STEPHENSON; C. MARSHALL; G.A. LOGAN; P.F. GREENWOOD Abstract Geochemical analyses of specimens of Reduviasporonites suggests that it is most likely of algal, rather than fungal origin. As probable alga, Reduviasporonites is unlikely to be integral to the process of mass extinction...

...William C. Elsik Abstract The fungal form-genus Reduviasporonites includes the range of morphology found in type and other material from Oklahoma and numerous well-preserved specimens from Italy and elsewhere. Chordecystia Foster 1979 and Tympanicysta Balme 1980 are both junior synonyms...

...Gordon D. Wood; William C. Elsik Abstract Specimens of the fungus Reduviasporonites stoschianus (Balme 1980) Elsik 1999 were recovered from the Copacabana Formation of Peru. Biostratigraphic data from smaller foraminifera, fusulinids and associated calcareous microfossils indicate that occurrences...

...Henk Visscher; Mark A. Sephton; Cindy V. Looy Abstract Throughout the world, latest Permian records of organic-walled microfossils are characterized by the common presence of remains of filamentous organisms, usually referred to the palynomorph genus Reduviasporonites . Although generally regarded...
