A conspectus of the families of Aphyllophorales Naturalis
Donk, M.A..
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...

A reassessment of the Cyphellaceae Naturalis
Donk, M.A..
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...

Book reviews Naturalis
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...

Check list of European Hymenomycetous Heterobasidiae Naturalis
Donk, M.A..
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...

Check list of European Hymenomycetous Heterobasidiae [Cont’d] Naturalis
Donk, M.A..
(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...

Check list of European hymenomycetous Heterobasidiae. Supplement and corrections Naturalis
Donk, M.A..
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.

Four new families of Hymenomycetes Naturalis
Donk, M.A..
Four new families are proposed, viz. Bankeraceae, excluded from the Thelephoraceae trib. Hydnelleae; Echinodontiaceae; Gomphaceae, for the Clavariaceae trib. Ramarieae in an emended circumscription; and Clavulinaceae, a former tribe raised in rank.

Matatti’s generic names for fungi Naturalis
Donk, M.A..
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.

Notes on Cantharellus sect. Leptocantharellus Naturalis
Donk, M.A..
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’.—I Naturalis
Donk, M.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...

Notes on ‘Cyphellaceae’—II Naturalis
Donk, M.A..
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 European polypores-I Naturalis
Donk, M.A..
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.

Notes on European polypores-II. Notes on Poria Naturalis
Donk, M.A..
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...

Notes on European polypores-III. Notes on species with stalked fruitbody Naturalis
Donk, M.A..
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...

Notes on European Polypores—VIII Naturalis
Donk, M.A..
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 resupinate Hymenomycetes—VI Naturalis
Donk, M.A..
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 the basidium Naturalis
Donk, M.A..
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...

Paullicorticium curiosum, presumably an imperfect state Naturalis
Donk, M.A..
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.

Racodium Pers. not a genus of Lichenes Naturalis
Donk, M.A..
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.
