We know only ESPER 'S descriprion and figures of this species. According ro rhar rhe corallires are of
different size and form , usually polygo nal, mostly pentagonal, 6 ro 8 mm in dia merer. Septa 30 ro 36,
alternating in length. 12 ro 16 reach the columella and bear paliform lobes.
A specimen wirhom label in rhe ESPER collection was designared by WIJSMA -BEST (1972 : 28) as
F. pentagona. But it has characrerisrics which we amibute now ro F. 11leliceru11l.
EC 68 is a speci men, co llected by KLUNZI NGER at Koseir. Corallum f1ar, surface irregular. Corallires
cerioid, polygonal, 6 ro 7 mm long and 5 ro 6 mm broad. Calices polygonal , rounded or oval. Wall up ro
1 mm , edges acute , Sepra continuous over rhe wall, larger ones fusing wirh smaller ones of the opposite
side, Sepra 24 ro 35 in number, 12 ro 17 reaching the co lumella, the remaining ones very small. Paliform
lobes conspicuous. Edges of septa fine ly dentate,
X2 : 1- 7 is an encrusting specimen with somewhat smaller corallites as in EC 68, on an average 4 x 6 mm ,
or 5 mm in diamerer. Dentarion of septa stronger, palifo rm lobes very distinct.
I 5 5889 has a hillocky growrhform, corallires 6 ro 9 mm in length, On flattened parts ca licular
snuctures correspond wirh rhe above description. Th e corallites ar rhe hillocks have more exsert and
srronger dentate sepra, thus the paliform lobes become inconsp icuous.
SLR 824, NS 8676 and NS 1913 are intermediare fo rms between EC 68 and NS 5889.
