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... |

(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... |

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. |

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... |

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 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... |

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”. |

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... |
