Taxonomy of
Pseudohydnum gelatinosum
and its sister taxa is revised via morphological data and a four-gene dataset (ITS, nc LSU rDNA,
TEF1
,
RPB1
). Identity of
P. gelatinosum
and
Tremellodon pusillus
is re-established based on newly collected and sequenced material from their type localities.
Pseudohydnum alienum
from Europe;
P. umbrosum
from temperate East Asia;
P. cystidiatum
,
P. meridianum
, and
P. placibile
from Vietnam; and
P. omnipavum
from North America are described as new to science;
P. translucens
and
P. brunneiceps
from East Asia are redescribed. Most
Pseudohydnum
collections from North America belong to
P. gelatinosum
ssp.
pusillum
. A significant divergence of
TEF1
sequences in
P. gelatinosum
is discussed.
