Notes.
Aspergillus doliiformis
represents a new lineage within the subgenus
Polypaecilum Polypaecilum
, series
Canini
, forming a fully supported clade (ML = 100%; PP = 1.0).
A. doliiformis
is phylogenetically closely related to
A. limoniformis
and
A. cylindricus
. However,
A. doliiformis
can be distinguished from
A. limoniformis
by their sequence similarity (93% 502/539; 99% 847/853; 87% 370/423; 91% 762/834; 92% 724/791 similarity of ITS, LSU,
TUB
,
RPB2
and
TSR1
in
A. limoniformis
CGMCC 3.19323). Morphologically, the conidia of
A. limoniformis
are limoniform or subglobose, rather than lantern, subglobose to globose, obpyriform in
A. doliiformis
(
Zhang et al. 2021a
). In addition, the distinction between
A. doliiformis
and
A. cylindricus
is shown in the notes of
A. cylindricus
.
