Lichens-L at [emailaddress email=”lichens-l@HAWAII.EDU”] is an email circulated to all lichenologists world wide. Within reason, lichenological questions can be asked and someone may answer.

Aptroot A. and Honegger R. 2006. Lichens in the New Botanical Garden of the University of Zürich, Switzerland. Bot. Helv. 116: 135 – 148.
The lichen flora of the 30 years old New Botanical Garden of the University of Zürich was investigated. In total 149 species of lichen-forming ascomycetes were found, including Red Listed species like Arthonia dispersa and Parmotrema perlatum. The following species were recorded for the first time in Switzerland: Bacidia adastra, Flavoparmelia soredians and Lecanora xanthostoma. 18 species of lichenized and 2 species of non-lichenized ascomycetes are new records for the Canton of Zürich. Our data are compared with published inventories of the epiphytic, foliose and fruticose lichens of the city of Zürich from the first and second half of the 20th century. A range of Peltigera spp. was transplanted to the most humid and shady part of the alpine garden and their growth and development monitored. Spontaneously growing and introduced lichen species in the relatively small Zürich Botanical Garden amount to almost 10% of all lichen species known from Switzerland.
