Material. SMF 23.022– SMF 23.027.
Description. Encrusting, partly multilayered colony, separate sheets 1.0– 1.5 mm thick. Autozooecia growing from thin epitheca, bending at their bases to the colony surface. Autozooecial diaphragms rare to absent, thin. Autozooecial apertures circular to oval. Lunaria well-developed, rounded, disappearing in deeper sections; ends of lunaria not indenting into autozooecia. Vesicles small to medium, high, separating autozooecia in 2–4 rows, 9–16 surrounding each autozooecia aperture, with rounded to flat roofs, polygonal in tangential section. Autozooecial walls granular prismatic, 0.005 –0.015 mm thick. Small maculae consisting of vesicular skeleton present, 1.0– 1.3 mm in diameter.
Remarks. Fistulipora guttata Trizna and Klautzan, 1961 differs from F. milleporacea Bassler, 1929 from the Lower Permian of Timor in smaller autozooecial apertures (average aperture width 0.28 mm vs. 0.35 mm in F. milleporacea ). Fistulipora guttata differs from F. enodata Gorjunova, 1970 in smaller apertures and larger distances between aperture centres (average aperture width 0.28 mm vs. 0.30 mm in F. enodata ; average aperture spacing 0.66 mm vs. 0.58 mm in F. enodata ), and in vesicles separating autozooecia.
Occurrence. Lower Permian (Artinskian) of Urals. Zhongba Formation, Permian (upper Cisuralian – Guadalupian); Zhongba area of southwestern Tibet .
