Reproductive organs and in situ spores isolated from early land plant Tichavekia grandis from the Kosov, Přídolí, upper Silurian of the Prague Basin are described in detail. Subspherical to reniform sporangia are 2.2–3.0 mm wide and 1.6–2.0 mm long, and are formed by a thick layer of coaly matter showing a marginal rim. Trilete crassitate in situ spores 17–32 µm in diameter have microgranulate, microspinate to rugulate sculpture of proximal surface and are not comparable with any dispersed and in situ Silurian spore taxa and, therefore, it may represent a new spore taxon. Palynological comparison with other cooksonioid taxa is made.
