Corallum encrusting on dead coral of same kind; growing edge free, slightly upturned, around 2 mm thick, lined with small corallites. Upper surface with prominent nodules of various height, one open at the top producing a small cup, 3 cm across at mouth..

Corallite very unevenly dispersed, without consistent plan on one vertical surface they are more than a calicinal diameter apart while on another of similar situation they are almost touching each other; generally within deep depression, corallites smaller, very crowded, slightly, protruding or level with surface but there are corallites of the same construction situated on place vertical surfaces - in latter situation the corallites are not crowded. Big corallites vertical, low truncated cones or cylinders, 3.5 mm diameter at base with calice 2 mm across, elevated up to 1 mm only. Smaller projecting corallites measure 2 to 2.5 m across at base, their calices correspondingly less than 2 mm. Flush corallites within deep depression only 1.5 mm or less in diameter. Those on peripheral area very distant, flush, 1-1.5 mm across. Calices mostly round; few oval. Fossa shallow.

Septa 16-24 in protruding corallites (usually 22-24 in big ones); wide, almost filling up calicinal space, reaching beyond radius midpoints before dropping into small oval calicinal fossa; edge almost entire, slightly crinkled, surface sparsely, finely granulate. Loculi not sharply cut from peritheca.

Columella quite prominent, oval, a tangle of tubercles, produced into keel (central ridge); in small level corallites, columella a single row of tubercles or a single small lamella.

Peritheca velvety in texture; very fine ridge and furrow system discernible, gyrating around corallites, the very thin ridges surmounted with very fine sharp spines. Tiny pores can be recognized on close examination with a lens.

Remarks:This species somewhat resembles T. tubifera. Its characteristic features are its growth and habit, its irregularly dispersed corallites, their diversity in size and height, and the calices appearing full because of the wide septa.
