W obrębie podrzędu Phillipsastraeacea autorka ustanawia nową rodzinę Marisastridae, obejmującą formy kolonijne o masywnych koloniach, bądź formy osobnicze. Cechą charakterystyczną nowej rodziny jest obecność wyraźnej epiteki, wrzecionowatych septów dwojakiej długości, złożonych tabul oraz brak podkówek. Do nowej rodziny zaliczono Marisastrum n.gen. i Ceratophyllum Gürich, 1896.
Famennian corals of the south-western part of the Holy Cross Mountains (Góry Świętokrzyskie) from Kadzielnia, Zaręby, Łagów (Dule), Gałęzice (Besówka), Kowala and Jabłonna are described in the present work. About 3,000 specimens have been collected and 55 species and 5 subspecies of 36 genera - described. A new family, Kielcephyllidae, two new subfamilies, Friedbergiinae and Guerichiphyllinae, 9 new genera, 36 new species and 5 subspecies have been erected. On the basis of a lithological analysis of beds, faunal assemblages and the preservation state of corallites, it has been concluded that in the Lower Famennian a shallow sea existed at Kadzielnia. It was temporarily connected with the open sea. The corals are mostly preserved there in a life-time place. At Zaręby, there was a lagoon with the remains of plants but with a normal salinity of water. In the Upper Famennian of Gałęzice, the sea water was well aerated and connected with the open sea. Fossils are broken but not worn off and, therefore, they were not transported. At Kowala, the sea was probably calm, not deep and well aerated. Index species for the Lower and Upper Famennian have been determined among the coral fauna examined. The age of individual zones has been determined by conodonts and where such were lacking, climeniids or trilobites. The history of the research of Famennian corals, which in general occur rarely and in monotonous assemblages, has been presented. To settle their generic assignment, the ontogeny of corals has been studied and the results were a basis for changes introduced to the classification. A few phyla have been distinguished and their phylogenetic relationships discussed.

On Upper Devonian habitats of rugose corals

100%
Frasnian deposits in Poland are mostly organogenic, forming biostromes and bioherms. The latter should be considered as reefs, because they are rigid, continuous structures, elevated above the sea floor. In the Holy Cross Mts they form a chain along the Dyminy anticline. Some communities of these bioherms are preserved in situ. The fauna in biostromes is mostly redeposited a short distance from the site of life. Depositional environments changed in the uppermost Frasnian becoming more terrigenous. The lower Famennian is characterized by intercalations of marly limestones and shales containing small horn-shaped corals, blind trilobites and small bivalves. Upper Famennian depositional environments were variable. External morphology of corals, shape of their calices, ornamentation of septa and arrangement of skeletal elements reflect their habitats.
In order to investigate the process of blastogeny and individual variations in tetracoral colonies, comparative studies have been made of t he following forms from the Middle and Upper Devonian strata of Poland: Disphyllum geinitzi L. & S., Hexagonaria laxa Gurich, Hexagonaria laxa jurkowicensis n. subsp., Peneckiella minor kunthi (Dames) and Sudetia lateseptata n. gen., n.sp.
Corals with horse-shoe dissepiments and resting on them trabecular fans , formerly included by the writer in the subfamily Pachyphyllinae Stumm, are now referred to the family Thamnophyllidae Soshkina. The systematic division of this family is given. An analysis of correlation between the number of septa and the diameter of calice or of tabularium (n/d or n/t) in genera Thamnophyllum Penecke, Macgeea Webster , Pexiphyllum Walther and Pachyphyllum Edward & Haime has made possible the determination of the range of individual variability and the elucidation of evolutionary tendencies within the quoted genera. The coefficient of correlation for particular species is of diagnostic value and may constitute their stratigraphical index . It has been established that species previously described and referred (Różkowska, 1953, 1956) to the genera - Pseudoacervularia Schluter and Pachyphyllum Edwards & Haime should be assigned to genus Pachyphyllum. Within this genus four groups of species , with peculiar, similar coefficients of correlation, should be differentiated. Conclusions concerning speciation have been deduced from biometrical treatment and from ontogenic and morphological studies. A description is given of the phyletic and chronological evolution of Thamnophylliae. In addition to material from the Holy Cross Mts. specimens collected at Dębnik and in the Sudeten were used by the writer for the present work.
11 species and subspecies of the genus Disphyllum de Fromentel are described from the Devonian of Poland, two of them, D. wirbelauense bonae and D. w. reaulare, are new. The geological structure of the Disphyllum-bearing localities from the Holy Cross Mts and Sudetes is discussed. The profiles of deep boreholes from Silesian-Cracow anticlinorium and Pomerania are presented. The coral's blastogeny and intraspecific variability are characterized. The septal index and pattern of internal structure are regarded as taxonomical criteria for specific identifications. It was noted that the microstructure is characterized by coarse monacanths distributed horizontally or in the form of half fans. Distribution of Disphyllum in Poland and in the world, the moment of its appearance and its biostratigraphical value are discussed.
