Compendium of All Fungi Known to Date

rarely has it happened, as mentioned, that species were assigned to a section not their own because their characters were not fully defined. Therefore, species must be searched for broadly under the various sections of a genus.

VII. I have appended less certain species to the end of each individual genus; indeed, I have added entirely doubtful species to the end of each suborder or order, not wishing to neglect any forms, because even fungi that are poorly defined today might be rediscovered and correctly described in the future.

VIII. Regarding secondary or metagenetic fungi (pertaining to the Ascomycetes sac fungi), I have generally only cited the names; the diagnoses, however, will be found under their own proper order.

IX. A few things should be noted regarding the systematic arrangement used. In each order, I have preferred that which seemed to me more correct and simpler among the systems of authors. Regarding the Pyrenomyceteae, Sphaeropsideae, Melanconieae, and Hyphomyceteae, I have used my sporological system combined with the vegetative [system] of the authors, having corrected what needed correction. If there is anything good, simple, and natural in this system, this universal mycography will surely demonstrate it.

X. If I deemed it necessary to add certain observations departing from those of the authors, I took care to have these printed between the signs « ».

XI. The index of mycological books (in truth, of almost all published to date) from which I excerpted the diagnoses is placed at the beginning of the Sylloge. If I have omitted certain books and therefore the diagnoses contained therein, it will then be easily apparent to mycologists.

*) I candidly confess that some errors, which were very easily avoided, have already crept in. Thus, species no. 881 is most evidently the same as no. 847; species no. 2171 is entirely the same as no. 2196. But readers will grant pardon, I hope, when they wish to remember that the nearly innumerable and multiform slips of diagnoses had to be arranged, selected, and ordered into a system by me through very long labor.
