The spores are uniseriate, colourless, 3-septate, fusiform, tapering towards the tips, 3—4 µ wide, 16—20µ long, with cubic cells. Pycnidia are not present. The species under consider- ation differs from Thelidium in its gonidia and the fusiform spores; from Porina in its goni- dia and the diffluent paraphy- ses. It represents, it would seem, a new genus. Although Pyreno- trichaceae have Scytonema-go- nidia the genus may be pro- visionally assigned to this family. Cyanoporina Groenh., gen. nov.

DONK * SUMMARY 1. The present paper is the first of a series intended to deal from a nomen- clatural point of view with all the generic names proposed for Hymenomycetes. For each name the following items are considered: (i) its etymology and gender, (ii) the original scope of the corresponding genus, and, in case of the name being- an isonym, also of the group covered by its basinym; (iii) the type species, which when not originally designated, is selected; (iv) its basinym, synisonyms, homonyms, typonyms, and variant spellings, if any, are indicated; (v) its status under the Rules is determined; and (vi) supplementary remarks are given when these are deemed useful. 2. This first instalment deals with "Cyphellaceae," a group defined in a con- ventional, rather descriptive, manner, not as a taxonomic unit. 3. A new generic name, Stromatoscypha Donk, is introduced for Porothelium (Pr. ex Fr.) Fr. 4. The following new combinations are made: Aleurodiscus digitalis (A. & S. ex Fr.) Donk [basinym: Cyphella digitalis (A. & S.) ex F r . ] , and Stromatoscypha fimbriata (Pers. ex Fr.) Donk [basinym: Polyporus fimbriatus (Pers.) ex F r . ] . INTRODUCTION TO THE SERIES.—A few words may be said about the origin of the present series. For about twelve years before World War II hit Java, I was engaged in the preparation of a "Genera of Hymeno- mycetes." It soon appeared that the application of many generic names was uncertain and rather than using them in a haphazard manner I tried to find out more about them in order to apply them as correctly as possible. This proved an arduous task. When it was completed, the "Genera" were sent to the printer's. As a consequence of the war, the text that went to the printer's, the already printed sheets, as well as the trunk containing the carbon-copy, nearly all of the notes on which the manuscript was based, and about 500 especially prepared illustrations were destroyed. However, a carbon-copy of the nomenclatural part, abandoned several years before the book was finished, was retrieved. It lacked, of course, all the corrections and additions made between its storing-away and the finishing-of the final manuscript. I have not seriously tried to cover once more the entire * Keeper of Herbarium Bogoriense, Kebun Raya Indonesia, — 199 — Binder5 Rein Vol 1, Part 2 pp 66 -220_Page_67 Rein Vol 1, Part 2 pp 66 -220_Page_68 Rein Vol 1, Part 2 pp 66 -220_Page_69 Rein Vol 1, Part 2 pp 66 -220_Page_70 Rein Vol 1, Part 2 pp 66 -220_Page_71 Rein Vol 1, Part 2 pp 66 -220_Page_72 Rein Vol 1, Part 2 pp 66 -220_Page_73 Rein Vol 1, Part 2 pp 66 -220_Page_74 Rein Vol 1, Part 2 pp 66 -220_Page_75 Rein Vol 1, Part 2 pp 66 -220_Page_76 Rein Vol 1, Part 2 pp 66 -220_Page_77 Rein Vol 1, Part 2 pp 66 -220_Page_78
