<strong>PART</strong> 2 THE 10¢ TOUR OF THE PYRENOLICHENS A TWENTY-YEAR PERSPECTIVE In 1975 I submitted my thesis which, while dealing primarily with Arthopyrenia s. lat., also included a primitive attempt to break away from Zahlbruckner's system, then in use. Over the ensuing 20 years my mistakes as regards Arthopyrenia and the more general system have become evident, new ideas and information have become available, critical specimens have been examined and a large number of new records have accumulated. This anniversary seems an appropriate time to try again. The system proposed is not intended in any way to be final but only an interim report. As noted in the introduction the title "tour" is given to this part so that I am free to pick and choose what is treated. This is not the proverbial 50¢ tour, only the 10¢ version, since I badly miscalculated the amount of errors, changes and specimens to be waded through. The most interesting part, the higher categories, is left undone. They naturally fall at the end of such a project since I have worked from the bottom (species) upwards. I do not like the current tendency to assign new genera, etc., to "incertae sedis". This conveys absolutely no information. It is useless. It is an admission of failure, of lack of general knowledge, of laziness, which one is surely forced to admit to on occasion but should not become a way of life. Given a choice, I have chosen to err on the side of controversy. This, I 50
hope, leads to more intensive study and ultimately to a better result. Nothing is set in stone. I do not consider some of the groups treated here to be lichens. Not only do I feel there is no consistent association with a photobiont, they fail the basic definition that requires some visible morphological evidence of interaction between fungus and photobiont. I have omitted for now perithecoid forms belonging to the Gyalectales s. lat. and Lecanorales. Also the non-lichen Mycoglaena, Micropeltidaceae, is omitted. The following table shows the changes over 20 years in the systematic arrangement of the corticolous pyrenolichens. Due to time constraints I have not been able to work through the mostly saxicolous Verrucariaceae nor the perithecioid genera of parasites/ parasymbionts, some of which probably are confamilial with lichen-forming taxa.
