Journal article (peer-reviewed)abstract
- A list of lichens collected on two field trips to Estonia by botanists from the universities of Stockholm and Lund in 1989 is presented. 74 species are reported for the first time from Estonia. Several other species have previously been reported only a few times. From the 11th to the 20th of June 1989 nine botanists from Stockholm visited Estonia and Latvia, and four lichenologists from Lund visited Estonia from the 8th to the 15th of July. The aim of the visits was to st udy the vascular plants and the lichens. Prof. Hans Trass, Tartu University, arranged both excursions in Estonia. Both botanist groups visited the western part of Estonia only, and most of the time was spent on and near the island of Saaremaa. Since some interesting lichens were collected during the two excursions, a list of the collected species from the localities in Estonia i9 presented here. The collections from Latvia will be dealt with in a separate publication.

Doctoral thesis (other academic/artistic)abstract
- The delimitation and nomenclature of the genus Chiodecton (16 spp.) and five related genera, Ancistrospora (1 sp.), Dichosporidium (6 spp.), Erythrodecton (2 spp.), Graphidastra (2 spp.) and Streimannia (1 sp.), are revised. The genera Ancistrospora, Erythrodecton and Streimannia are described and Graphidastra is erected as genus. Also, two new Chrysothrix species are described. A key of all species is given as well as typification and photos. A hypothesis of the cladistic relationships of all species but Chrysothrix granulosa and C. placodioides is presented and discussed.
