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... |

This is, I believe, the most important single contribution in the field of Hymenomycetes for years. The author was attracted to the group commonly known as Clavariaceae as early as 1925 when in England; he continued his studies when working on the staff at the Singapore Botanic Gardens and after his return to England. He got the conviction that before science could undertake a wholesale revision of the present classification of Hymenomycetes, the larger constituent groups should be worked over, one at a time, and ‘their particular kind of fruit-body described in terms of hyphal properties’, and that to omit the tropical element would mean certain failure. Thus, the aims of this admirable volume become clear: a large number of species of “Clavariaceae“ are... |

The terminology of the basidium became complicated when Neuhoff (1924: 256) introduced the term epibasidium for various extensions (exclusive of sterigma-tips) from basidia. Such diverse organs as (i) extensions from probasidia, like the four-celled body producing the sterigmata in Auricularia Bull, ex Mérat, and (ii) extensions from metabasidia, like the sterigmata (minus tips) of Tremella Fr. and Tulasnella J. Schroet., all became epibasidia. Neuhoff’s views were enthusiastically defended by Rogers (1934), then a pupil of Dr G.W. Martin, and they have been upheld by Martin himself (1938) and other mycologists of his school, which concerns itself particularly with the Heterobasidiae. Neuhoff’s terminology has been rejected or criticized by various... |

The author regards the Cyphellaceae as an artificial family. He redefines it for practical purposes, suggesting the gradual removal of those elements that show relationship with other groups; several elements are referable to the Corticiaceae or the agarics. A list of the ‘cyphellaceous’ generic names tentatively included is given. The genera to be excluded from the family as defined are briefly discussed. The same applies to a long series of specific names that had or have been included. A historic chapter reviews some important developments in regard with some of the older genera, Solenia, Cyphella, Aleurodiscus, as well as the rise of the family. Some species are transferred to Aleurodiscus Rab. ex J. Schroet.; Cytidia Quél. is redefined and... |

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... |

The author introduces two new genera, Mniopetalum Donk & Sing, (based on a new species, M. globisporum Donk) and Episphaeria Donk (based on Cyphella fraxinicola Berk. & Br.). Three other genera in an emended circumscription are discussed: Stigmatolemma Kalchbr., Phaeosolenia Speg., and Cyphellopsis Donk. Rhodocyphella W. Cooke is reduced to the synonymy of Stigmatolemma; and Maireina (Pilát) W. Cooke, to the rank of a section of Cyphellopsis, which is tentatively considered to consist of a single complex species for which the name Cyphella monacha Speg. apud Roum. is temporarily used. New combinations are made in Mniopetalum (1), Episphaeria (1), Stigmatolemma (3), Phaeosolenia (2). Most of these names are used (but not validly published) in a... |

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... |

1. The conidiophores which caused the publication of the genus Tomentella J.-Olsen apud Bref. bear no relation to the basidiferous states with which they were associated. They belong to Ostracoderma Fr. The names based on these associations are nomina confusa. — 2. Peniophorella P. Karst. is an other instance of a nomen confusum: it was based on Hyphoderma puberum to which species foreign spores were ascribed. These two-celled spores induced the introduction of the genus. Some additional species are referred to Hyphoderma Wallr. emend. (two new combinations). — 3. The name Phanerochaete P. Karst. is re-introduced for an as yet not sharply delimited genus, the possible characters and limits of which are discussed. — 4. It would appear that the correct name... |

The author gives a recapitulation of the families of the Aphyllophorales. He is inclined to recognize 21: the families he is not (yet) prepared to uphold are discussed. The synonymy of the order and the families above the rank of genus is listed, but it is avowedly incomplete. The treatment of each family does not go further than the mention of the included genera, but through selected references cited for each genus in a special list, an introduction to the separate genera is provided. An introductory chapter contains some general remarks and discusses a number of terms used in connection with the treatment of the families. New taxa are, Brachybasidiales, Hericiaceae, Punctulariaceae, Asterostromatoideae, Pteruloideae, while the name Septobasidiales Couch... |

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... |

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... |

A suitable subtitle for this paper would have been “The rise and fall of a family”. What is usually called the Cyphellaceae is an instructive example of a situation not uncommonly encountered in the current systematics of mycology: a family retained in a traditional sense by some mycologists and considered by them as good a family as any, while others are convinced that it is nothing but a handy bin from which part of the contents has already been taken out and disposed of by scattering it over various groups, but which is still needed for keeping what remains. We do not yet know what to do with this considerable remainder, mainly because the published accounts are inadequate and the species have not yet been scrutinized anew in the light of present-day... |

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”. |

In an attempt to bring the nomenclature of several European polypores up to date Datronia gen. nov. is published to obtain a correct name for Antrodia P. Karst. sensu Murrill; and several new specific combinations are made, viz. with Datronia (2), Antrodia P. Karst. emend. (6), Rigidoporus Murrill (3), Oxyporus (Bourd. & G.) Donk (1), Phellinus Quél. (1). In a few cases annotations are attached to names in current use or to recombinations. Cartilosoma Kotl. & Pouz. is reduced to the synonymy of Antrodia. |

With this check list an attempt is made to account for the recorded European species of those Basidiomycetes that Patouillard called the “Hétérobasidies”, excluding, however, the Uredinales and Ustilaginales. Therefore, it covers the Septobasidiales, Tremellales (comprising the Auriculariineae and Tremellineae), Tulasnellaceae (Corticiaceae with repetitive basidiospores), Dacrymycetales, and Exobasidiales. Of each species admitted the synonyms at the specific level are listed as are also references to selected descriptions and illustrations. Notes on taxonomy, synonymy, and nomenclature are appended to a considerable number of entries. A final chapter not only recapitulates alphabetically the names appearing in the check list proper: it also deals briefly... |

(62). In some respects Tremella encephala is even more variable than other species of the genus, for instance, as to colour, there are at least three principal shades. First, hyaline-whitish, the white colour being mainly due to the white kernel that shows through. It was this condition, I believe, that received the name Tremella alabastrina. A delicate flesh colour is very common. Neuhoff (1936b: 23) has suggested that Tremella fragiformis Pers. (which Persoon called ‘ruber’) was annotated by its German collector as stawberry (fraise) coloured and that Persoon misunderstood the information: “in der deutschen Tuchindustrie bedeutet fräsfarben ein milchiges Fleischrosa, das dem Farbton der T. encephala vollkommen entspricht.” It may be pointed out that when... |

A note on lampro- and skeletocystidia and the introduction of the new term ‘gloeoplerous hyphae’ for the hyphal system that often produces the gloeocystidia in the hymenium is followed by a historical survey of the generic names proposed for resupinate and effused polypores (the so-called porias) and by an enumeration of these names and their type species together with a key to these species as far as they occur in Europe. Emended descriptions are given for Chaetoporellus Bond. & S., Chaetoporus P. Karst., and Schizopora Velen., while the name Perenniporia Murrill is re-introduced for the group of Poria medulla-panis sensu Pers., the species now often taken as type of the name Poria Pers. per S. F. Gray. It is proposed that this last-mentioned name be... |
