In other terms, no sterile secondary laterals would exist, a situation found, for example, in the Recent Bornetella nitida.

According to Barattolo et alii "Although the kind of reproduction endosporous or cladosporous is a high taxonomic character, their evidence is lacking in most of fossil taxa Consequently, the diagnosis of Triploporellaceae ought to include both endosporous and cladosporous reproduction.

Of them only two, S. Genus Clypeina Michelin, Fig. Excerpts of the description are as follows: Whorls made up of primary and secondary branches.

Primaries, long and cylindrical tubularsometimes slightly dilated distally; they are perpendicular or more or less inclined to the axial cavity. Secondaries, shorter and widening distally; they occur as a bush around the distal end of primaries. Sometimes the branches may be coalescent either proximally or les algues vertex a longer part of their tract Due to the les algues vertex calcification of the axial cavity, the alga is fragile and may be found only as fragments representing branches or part of them.

Short, phloiophorous secondary laterals are clustered at tip of the primaries. These values do not widely differ from the known species of Rajkaella.

Nearly transversal section of Rajkaella? Only two orders of laterals are found in these species, instead of the three in Linoporella. The diagnosis in Bucur et alii is as follows: The tubular secondary laterals enlarge towards the distal end phloiophorous typethat most probably, formed a cortex at the outer les algues vertex of the thallus.

Reproductive structures were situated very probably inside the central stem endosporate. Such a minor difference is considered significant only at the species level. Conversely, when les algues vertex the species recently assigned to Steinmanniporella, e.

Spaced out whorls of numerous, slender, acrophorous primary laterals, perpendicular to or slightly tilted upward from the main axis.
