“…Some discussion is also needed in regard to the possible occurrence in Ireland of another species of Trentepohlia with globular cells, Trentepohlia monilia De Wildeman, for which Printz (1921, , p. 23) erected a separate genus, Physolinum. This species, described by De Wildeman (1891, , p.140) for corticolous plants from Chile, has been reported for several tropical (Printz 1921, Nielsen 1954, Flint 1959) and warm‐temperate localities (Handa and Nakano 1988, Davis and Rands 1993, Noguerol‐Seoane and Rifón‐Lastra 1997). Khan (1951) recorded growth of this species in an agar plate inoculated with material scraped from a bark of tree in Wimbledon, England, and subsequently De Valéra and Ó Séaghdha (1968) used the same name for plants from Galway.…”

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 Њ 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.
