23 species found in the Hornsund area and Sorkapp I'and are<br />
reported from spitsbergen tor the fitst tine. References<br />
are given to the Tichenological Titerature of spitsbergen.<br />
The lichenflora of Spitsbergen is rather well known through numerous<br />
studies carried out during nore tban 200 years. Lindblorn<br />
(18{O) listed 63 species so far recorded fron the area and Lynge<br />
(1938) gave a survey of the lichens published by then including<br />
his own coll.ections of nacrolj.chens. Unfortunately he died before<br />
he could finish bis treatment of the nricrolichens- t{attick (1950)<br />
gave a detailed survey of the tristo<strong>ry</strong> of exploration- Ho$tever, the<br />
lack of a recent checklist nakes it a little risky to report species<br />
new to the area. as smaI1 contributions can easily be over-<br />
Looked, and we apologize for any nistake in our list. In tbe present<br />
nork we list the nrain contributions and all recent works }te<br />
know dealing specifically with the lichenology of Spitsbergen' and<br />
furthernore we have checked several revisions of genera and identification<br />
keys, e. g. Lanb (19??) and Poelt (1959)-<br />
The first author collected the lichens reported here as part<br />
of phytosociological work during two expeditions of the ilagief,lonian<br />
University in 1982 and 1985. Tbe second author assisted with<br />
sone of the identifications and made the literature survey. The<br />
col.lections have been deposited at KRA.<br />
