Abstract:
A new species, Chylocladia wynnei sp. nov., is described
from the Mediterranean Sea. It consists of 2-4 terete,
unbranched erect axes, 5-10(-13) mm high, arising from
a discoid holdfast. Axes, covered by a thick mucilaginous
layer, are hollow throughout. They are divided into segments
by monostromatic diaphragms and are constricted
at the diaphragms. Axes have a unilayered cortex and
longitudinal filaments lining their inner surface; gland
cells are cut off from these filaments. Gametophytic
plants are dioecious and consist of only two segments.
Male thalli have spermatangia in superficial sori located
between the two segments. One or two spherical sessile
cystocarps are borne on the distal part of the basal segment.
Tetrasporic plants comprise 45 segments; tetrahedrally
divided tetrasporangia are scattered throughout
the thallus. These sporangia are transformed from larger
cortical cells and, when mature, they protrude into the
thallus cavity. Diminutive stature and unbranched erect
axes covered with a thick mucilaginous layer clearly distinguish
C. wynnei from previously described species of
Chylocladia.
