| When Dr. Cunningham died in 1962 the manuscript of this monograph was still uncompleted. Miss J. M. Dingley, with the assistance of her staff, undertook to make it ready for publication. The result is a well-edited companion-volume to the previously published “The Thelephoraceae of Australia and New Zealand”. Only species are included ‘authentic’ specimens of which were examined. Under a section “Unknown and Rejected Species” a long list of names is given “of species listed by earlier workers but of which specimens have not been available for study, are not in the region, or which were based on faulty identifications”. |

| Referring to the author’s own words (A monograph of Cantharelloid fungi, 1966: 2) one is perfectly justified in qualifying the present book as “another need ... fulfilled.” It is a rare accomplishment for a botanist, after having spent a full life in the tropics and occupying himself there with a variety of subjects, to offer the mycological world his third monograph. The author is to be congratulated on the completion of this work. |

| There are few groups, even among the notorious pyrenomycetes, that have been the source of new species to such an extent as the one covered by this monograph. Its author recognizes a big central and rather heterogeneous genus Pleospora (with 100 species) and some affiliated smaller genera, Platyspora, a new genus (3 species), Clathrospora (8 species), and Pyrenophora (7 species). 71 species are excluded from these genera. Dr. Wehmeyer had very profitable hunting, judging from the vast number of synonyms he admits and discusses under the accepted species. One would conclude that quite a number of the species as he defines them are broadly conceived or very variable. In the Chapter “Nomina dubia, confusa, nuda, etc.” 62 specific names are treated; and in the... |

| During the manufacture of paper living organisms may be the cause of undesirable slime deposits (consisting of bacterial colonies and fungus hyphae) in the machines. An extensive literature on this subject has accumulated and many of these fungus species have been isolated and described. The aim of Mrs. Wang's investigation is not only to determine the species and their frequency in pulp and paper mills in New York State, but also to provide a compendium describing and illustrating the fungus species in order to facilitate their recognition by workers in this field of microbiology and mycology. Following a “Review of Literature” and a chapter on “Materials and Methods” there is a chapter entitled “Results and discussion”. The bulk of the contents, however,... |

| The genus Hygrophorus is perhaps one of the most attractive among the genera of the Agaricales. It is surprising, therefore, that no full treatment of this genus in Europe has ever been published. Doubtless, European mycologists will be strongly stimulated by this American monograph in which 244 taxa are described and 116 illustrated by excellent black and white photographs. Of these 244 taxa, 41 are new to science: about 65 occur also in Europe. The European mycologist will be astonished by the strikingly high number of taxa in this monograph. The “Flore analytique” of Kühner & Romagnesi covers 80 species and varieties of Hygrophorus and there are 86 in the second edition of Moser’s “Die Röhrlinge, Blätter- und Bauchpilze”. Though the actual number of... |

| In dieser Arbeit gebe ich den zweiten Teil einer Revision der niederländischen Heterobasidiomyceten und Homobasidiomyceten -Aphyllophoraceen. Der erste Teil, der in holländischer Sprache erschien (Mededeelingen Nederl. Myc. Vereeniging Bd. 18—20, 1931), war in Anlage und Behandlung kürzer gehalten. Auch diesmal beruht die Bearbeitung auf denselben Sammlungen, wie die Revision usw. von Oudemans und die darauf folgenden Veröffentlichungen hauptsächlich von der Hand von Frl. C. Cool in den Mededeelingen van de Nederlandsche Mycologische Vereeniging. Es stellte sich nämlich heraus, dass ein grosser Teil des Materials, auf dem diese Arbeiten basieren, in mehr oder weniger gutem Zustande erhalten geblieben war. Ausserdem habe ich selber im Laufe der Jahre, in... |

| The family is taken in a broad, artificial sense, but exclusive of the Boletaceae and ‘Meruliaceae’ sensu lato. Of the generic names treated 229 are considered validly published, 37 not validly published, and 6 are excluded. Of each name details are given on various nomenclatorial aspects such as valid publication, typification, homonymy, status (legitimacy). The new combinations Flaviporus brownei (Humb. per Pers.) Donk and Xerotinus afer (Fr.) Donk are proposed. Attention is drawn to brief remarks made in connection with Elmerina cladophora (Berk.) Bres., Polyporus scabrosus Pers., Chaetoporus tenuis P. Karst., Polyporus medulla-panis (Jacq.) per Fr.; to the synonymy listed of Merulius alveolaris DC. and Hexagonia mori Pollini; to the valid publication... |

| After a distinguished career as a collaborator of Prof. Hugo de Vries, the famous geneticist, Karel Bernard Boedijn (born June 29, 1893, at Amsterdam) became a mycologist, and it is in this latter capacity that he will be primarily remembered. He had already started to pay attention to the fungi during his Amsterdam period when C. van Overeem, Miss D. M. G. de Haas (who later married van Overeem), and Boedijn banded together and called themselves the “Mycologisch Museum te Weesp”. They started building up a collection which, however, never became very big. After some years van Overeem accepted a position in the Herbarium of the Botanic Gardens at Buitenzorg (now Bogor) in Java, where he died after a short but active period (1921-1927). The collections on... |
