Abstract:
On the basis of field and culture investigations,
five species of the genera
Trentepohlia
and
Printzina
were found to occur in urban habitats in western Ireland:
Trentepohlia abietina
(Flotow) Hansgirg,
T. aurea
(Linnaeus) Martius,
T. iolithus
(Linnaeus) Wallroth,
T.
cf.
umbrina
(Kützing) Bornet, and
Printzina
lagenifera
(Hildebrandt) Thompson et Wujek. These
species formed perennial populations on a variety of
substrata.
T. abietina
occurred on bark of trees;
T.
cf.
umbrina
occurred on stone walls; and
P. lagenifera
grew on several substrata, mainly cement and asbestos
sheeting.
T. aurea
and
T. iolithus
were found on
old concrete and cement walls; in particular, the latter
species formed characteristic, extensive, deepred
patches on many buildings. In culture, best
growth and reproduction of these species were observed
at 10 and 15 C, 16:8 h light:dark. Both in culture
and in the field, reproduction took place by release
of biflagellate swarmers behaving as asexual
spores, germinating to produce new plants without
any evidence of sexual fusion; release of biflagellate
swarmers in the field was generally observed in all
seasons throughout a whole annual cycle. Confirmation
of the occurrence of sexual reproduction in
Trentepohlia
was not obtained.
