In the Kupa River, the species was growing in small patches, on periodically flooded, slightly inclined and not particularly shaded limestone rocks on riverbanks.The moss was well developed, but without capsules. The accompanied species were
Brachythecium rutabulum
,
Cratoneuron filicinum
,
Fissidens crassipes
Wilson
ex
Bruch & Schimp.
,
Hygrohypnum luridum
(Hedw.) Jenn.
,
Marchantia polymorpha
L.and
Palustriella falcata
(Brid.) Hedenäs
, while in the running water only
Cinclidotus riparius
(Host
ex
Brid.) Arn.
,
Fontinalis antipyretica
Hedw.
and
Rhynchostegium riparioides
(Hedw.) Cardot
were present. In the Čabranka River the species was scarce, also growing on periodically flooded limestone rocks on the riverbank, but in comparison to the previous locality the habitat was shaded by trees (
Alnus glutinosa
(L.) Gaertn. and
Salix alba
L.). The specimens were without capsules. Other species found were
Brachythecium mildeanum
(Schimp.) Schimp.
,
B. rivulare
,
Cratoneuron filicinum
and
Fissidens crassipes
. In the watercourse, bryophyte flora consisted of
Cinclidotus aquaticus
(Hedw.) Bruch & Schimp.
,
Fontinalis antipyretica
and
Rhynchostegium riparioides
.
Both localities are not situated in the Mediterranean part of
Croatia
. All examined specimens had acute, sharply and irregularly toothed leaf apex, weak teeth on dorsal surface of nerve and weak papillae on lamina cells, all of which are characteristic for
D. flavescens
(
Werner 2002
)
. On the other hand, ratio of leaf length and width was 4.0-4.2, which is close to values for
D
.
pellucidum
(
Werner 2002
)
. Although many authors have recognized it at species level (see
Werner 2002
), others have treated it as a variety of
D. pellucidum
(
Frey
et al.
2006
)
, or placed it in the synonymy with the latter (
Brugués & Ruiz 2015
), due to the uncertain delimitation of these taxa.
D. flavescens
is a Suboceanic Montane species (
Düll 1984
), present in Western, Central and Northern Europe (
Hodgetts 2015
). In SE Europe it is known only from
Montenegro
(
Papp & Erzberger 2011
) and
Romania
(
Stefănuţ & Goia 2012
), in latter being VU (
Stefănuţ & Goia 2012
). From neighbouring countries it is known from
Italy
(
Aleffi
et al.
2008
).
