SABIIA - Sistema Aberto e Integrado de Informação em Agricultura (Sabiia)

In an analysis of the history of the names Polyporus frondosus (Dicks.) per Fr. and P. intybaceus Fr. the author delves back as far as 1552; he concludes that the two taxa were introduced for a single species. — The genus Oligoporus Bref. is restored and its type species ( O. farinosus Bref.) identified with both Polyporus rennyi B. & Br. and Ptychogaster citrinus Boud. — One new specific combination is made in each of the following genera: Oligoporus Bref., and Pycnoporellus Murrill. — 15 specific names are discussed for different reasons.

Notes on Cantharellus sect. Leptocantharellus

Ano: 1971

URL: http://www.repository.naturalis.nl/record/531937

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.

Notes on ‘Cyphellaceae’—II

Ano: 1969

URL: http://www.repository.naturalis.nl/record/531681

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...

Notes on resupinate Hymenomycetes—VI

Ano: 1962

URL: http://www.repository.naturalis.nl/record/531957

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...

Notes on European polypores-III. Notes on species with stalked fruitbody

Ano: 1962

URL: http://www.repository.naturalis.nl/record/532039

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...

Check list of European Hymenomycetous Heterobasidiae

Ano: 1969

URL: http://www.repository.naturalis.nl/record/532400

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...

Notes on ‘Cyphellaceae’.—I

Ano: 1966

URL: http://www.repository.naturalis.nl/record/531991

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...

Revision der niederländischen Homobasidiomycetae-Aphyllophoraceae

Ano: 1959

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...

A reassessment of the Cyphellaceae

Ano: 1933

URL: http://www.repository.naturalis.nl/record/534993

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...

Matatti’s generic names for fungi

Ano: 1966

URL: http://www.repository.naturalis.nl/record/534953

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.

Check list of European hymenomycetous Heterobasidiae. Supplement and corrections

Ano: 1975

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.

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.

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,...

Racodium Pers. not a genus of Lichenes

Ano: 1967

URL: http://www.repository.naturalis.nl/record/531998

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.

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...

Donk, M.A.; Maas Geesteranus, R.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...

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.

Book reviews

Donk, M.A.; Jansen, P.; Wit, H.C.D. de.

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...
