MycoBank No.: MB 844732.
Etymology
:—
Named after Safaga city, where the
holotype
was collected.

FIGURE 1
. Phylogram generated from maximum likelihood analysis (RAxML) based on a combined SSU and LSU rDNA sequences dataset for
Safagamyces marinus
with related genera in the
Halosphaeriaceae
. Representatives of
Xylariales
were used as outgroup. Bootstrap support on the nodes represent ML and MP ≥ 50%. Branches received Bayesian pp ≥ 95% are in bold. The new species is in blue.
Notes:—
Molecular phylogenetic analyses of SSU and LSU rDNA placed
Safagamyces
as a basal branch to a node that contains the three asexual marine genera:
Cirrenalia
,
Cucurbitinus
and
Pseudolignincola
. However, its molecular position along with its morphology warrant a generic separation. Morphologically,
Safagamyces
shares common characters with
Cirrenalia
and
Cucurbitinus
in having conidial cells constricted at the septa and increasing in size and pigmentation from the base to the apex (
Meyers & Moore 1960
,
Liu
et al
. 2020
). However,
Safagamyces
differs from the two genera by having branched conidia with sympodial conidial proliferation.
Pseudolignincola
is different from
Safagamyces
in having unicellular, dark-brown conidia and its teleomorphic stage have clavate asci with truncate, thickened apex, a pore and plasmalemma retraction and cylindrical ascospores without appendages (
Jones
et al
. 2006
).
