196 REINWARDTIA [VOL. 1 I have examined the type of P. andaiense at Kew. It consists of two detached pinnae, which agree in all characters with Christensen s de- scription. This species approaches Pleocnemia in venation, owing to the narrow lamina of the pinnules (which admits of little anastomosis of veins), but there can be no doubt that it belongs to Arcypteris and not to Pleocnemia, owing to its close resemblance to A. brongniartii. It differs from all species of Pleocnemia in its adnate pinnules, and in their shallow lobes. . The sinus-teeth (as seen in the type of P. andaiense), occurring m the distal sinuses only, are short and broad. The spores have a folded perispore, with rather much anastomosis of the folds.

GROBNHART ** CYANOPORINA GROENH., AN INTERESTING LICHEN FROM JAVA Amongst the lichens sent by the late Mr C. C. Schroter at Tjibodas (West Java), a peculiar blue-grey species drew my attention. At first sight I intended to assign it provisionally to Collemaceae indeterminatae, but on closer examination I doubted whether it was really a species of Collemaceae. Therefore. I examined it more carefully, with the following result. The granular thallus grows in smaller to larger patches over mosses, lichens, and detritus on bark. Soredia and isidia are absent and the thallus is not surrounded by a dark hypothalline line. The granular appearance of the thallus is caused by the relatively large gonidia, which belong to Stygonemataceae. The yellowish green cells are rounded, angular to semilunate, 8—12µ, wide and 10—15 µ long; one or more of them are enclosed within a gelatinous, colourless to pale citrine sheeth 4—6 µ thick. These clusters of gonidia are held together by the thalline hyphae constituting in this way a homoiomeric thallus. There is some resemblance with the thallus of Moriolaceae but in this family the gonidia are totally surrounded with a network of short hyphae lying close together. In the thallus of Cyanoporina, as I call this new lichen, such a network does not exist. The hyphae lie irregularly around the gonidia and cover them but partly. These gonidial hyphae are 2—3µ thick and possess very short cells. The thalline hyphae are 3 µ, thick, with inconspicuous lumen. Even with the aid of a dissecting microscope the perithecia are almost* invisible. Most of them are covered by the granules of the thallus. Yet the thallus is abundantly fruiting and in sections perithecia are always present. They are globose, 110—130µ in diameter, pale fulvescent to yellowish, with a pseudoparenchymatic wall 10—12 µ thick, composed of densely interwoven hyphae. I could, not discover a pore. The paraphyses are diffluent and only fragments were found.

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 — Binder3 Rein Vol 1, Part 2 pp 66 -220_Page_66 Rein Vol 1, Part 2 pp 66 -220_Page_67
