Fistulipora pavimenta Bigey, 1988 ( Fig. 3A, B ).— Two cystoporate colonies were collected at Laskowa Quarry. The upper Givetian age of Holy Cross specimens corresponds well with the type horizon of this species in the upper Givetian of Ferques, northern France (Couderousse Member of Blacourt Formation, Bigey 1988a) .

Canutrypa francqana Bassler, 1952 ( Fig. 3C–F ).—Middle Frasnian marly−organodetrital Wietrznia Beds (set C at Górno) have provided very abundant zoaria of this species. In addition, this fistuliporid occurs in uppermost Givetian strata at Łgawa Góra (Jaźwica Mbr.) and Chęciny (Zamkowa Góra, lower Chęciny Beds), as well as in the basal Famennian Kostomłoty limestones at Kostomłoty. The species was previously described only from the middle Frasnian strata of France (Ferques Formation, Bassler 1952; Bigey 1988a, b; see also Bassler 1953; Utgaard 1983) and Belgium ( Dessilly 1961).

Eridopora orbiculata ( Kiepura, 1973) .— The cystoporate species occurs in upper Givetian Laskowa Góra Beds at Górno, but was originally described from the uppermost Eifelian Skały Beds at type locality (Łysogóry Region) by Kiepura (1973) with the generic assignment to Ceramoporella .
