clavate

Included in both these genera were short, rectilinear borings with 'clavate' ends and elongate, curvilinear borings with or without swollen terminations.

It is very similar in form in that the labellar trichomes are unicellular and 'clavate' with ‘stalks’ of varying lengths.

Apart from size, the two specimens agree in all respects with the possible exception of the disposition of the 'clavate' laterals.

Mature thalli of both taxa have structures with a 'clavate' form located along the upper part of the main axis, and in both taxa these are preceded by multiple verticils of long, branched, hairlike sterile laterals.

All were united in having a characteristically 'clavate' glabellar shape.
