| The generic names for fungi used by Maratti in his ‘Flora romana’ must be accepted as validly published. Notes are given on the validly re-published names. Of these Agaricum and Coralloides may cause some difficulties. Conservation of Fomes (Fr.) Fr. against Agaricum [Mich.] Maratti is proposed. To the nomina rejicienda of the conserved name Ramaria (Fr.) Bon. Coralloides [Tourn.] Maratti should be added. |

| 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... |

| Paullicorticium curiosum Parm. werd beschreven als een primitieve vertegenwoordiger van de Corticiaceae. Een nauwgezette studie van de beschrijving en de figuren liet echter weinig twijfel, dat het hier ging om een conidiaal stadium van een soort van Hyphoderma Wallr. emend. Donk, waarschijnlijk H. populneum (Peck) Donk of een nauw verwante soort. De nieuwe combinatie Oedocephalum curiosum (Parm.) Donk wordt voorgesteld. |

| 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... |

| 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... |

| Racodium Pers. per Fr. 1821 (starting-point date of nomenclature, 1821) has to be typified by Racodium cellare Pers., which makes it a genus of imperfect fungi (Deuteromycetes). Even if Racodium Fr. 1829 is accepted as a genus nomenclatively distinct from Racodium Pers. per Fr. 1821 and as such is referred to the (imperfect) lichens (starting-point date, 1753), it still must be rejected as a later homonym. Zasmidium Fr. 1849 is another name for Racodium Pers. ex. Fr. 1821 and a later synonym of it. For the lichen genus Racodium Fr. 1829 the substitute name Rhacodiopsis Donk, nom. nov. is introduced and for its type species the name Rhacodiopsis rupestris (Pers. per. S. F. Gray) Donk, comb. nov. |

| Cantharellus sect. Leptocantharellus Peck is an earlier name for Cantharellus subgen. Phaeocantharellus Corner. The European species fall apart in two groups (Lepto-Plicati and Lepto-Phlebini) on the basis of the hymenophoral configuration. Most of the older names provided in profusion for the few European species of the section are scrutinized for the correctness of their application. The author prefers the name Cantharellus tubaeformis Fr. 1821 for what is often treated as two (or more) species, C. tubaeformis and C. infundibuliformis; he selects the name C. xanthopus (Pers.) Duby for Craterellus lutescens sensu Fr. Attention is drawn to what may appear to be a distinct species, viz. C. melanoxeros Desm. |

| 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... |

| 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”. |

| 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... |

| 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. |

| For the most part the species or specific names discussed belong to the genus Polyporus sensu stricto; a few of them belong to Albatrellus S. F. Gray and Coltricia S. F. Gray. It appears not only that the taxonomy of many species is far from settled but also that quite a number of protologues have never been scrutinized with care. Here an attempt is made to emend the names of a number of species. Further studies are needed before some of these species can be definitively delimitated and their nomenclature determined. Polyporus agariceus (König) ex Berk. sensu Bourd. & G. is called P. anisoporus Mont.; P. picipes Fr., P. badius (Pers.) ex S. F. Gray; P. lentus Berk, and allied forms are referred to P. floccipes Rostk., &c. A recapitulation at the... |

| 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... |

| 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... |

| This continuation of the “Check list of European hymenomycetous Heterobasidiae” (published in Persoonia 4: 145-335. 1966) contains supplementary matter as well as corrections. — Ypsilonidium (Donk) Donk is published as a new genus. Two new specific combinations are made with this generic name. — Muribasidiospora Rajendren is at least tentatively reduced to Exobasidium. — Following Parmasto, Exobasidiellum Donk is removed from the Tulasnellales. |

| 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... |
