| In the present paper Irpex is maintained as a monotypic genus, while Steccherinum is accepted with 17 species. Of these S. ethiopicum, S. galeritum, S. gilvum, S. lanestre, and S. willisii are described as new species, S. hydneum is proposed as a new combination. A considerable proportion of the paper is devoted to all the species (and a few subspecific taxa) that have been wrongly described in or transferred to Irpex and Steccherinum. Some of the specific epithets are transferred to other genera, such as Beenakia (p. 555), Climacodon (p. 546), Dentipellis (p. 551, 558) and Hyphodontia (p. 567). |

| A revision of the genera Geoglossum, Microglossum, and Trichoglossum as represented by collections made in West Pakistan, India, Nepal, Sikkim, and Tibet is given. Several species from this area are recorded for the first time. Geoglossum glabrum, albeit not indigenous, is discussed and shown to be a nomen dubium; the name as used in the sense of Nannfeldt is replaced by G. sphagnophilum. The name Geoglossum nigritum is a misapplication, so that for it G. umbratile is re-introduced. Geoglossum umbratile var. heterosporum is a new combination. |

| In 1949 a trip was made to Kenya Colony, British East Africa, with the aim of collecting Phanerogamic plants and Ferns. The intention was to collect 12 sets of each number which I managed to do for about 70 %. Except for the first set which will be incorporated in the Rijksherbarium, the plants will be sold to those institutes in Europe, S. Africa and America which had subscribed in advance. It is expected, however, that a few more sets in excess of the 12 aforementioned will be available. It should be noted that these will prove rather incomplete, numbering less than 30 % of the total amount. |

| The first edition of the present book, entitled “British cup fungi and their allies,” was welcomed among others with the words “. . . the only reasonably complete synthesis of modern thought on Ascomycete classification known to this reviewer.” (Korf in Mycopath. Mycol. appl. 16: III. 1962). These words have lost nothing of their truth and could have been written with equal justification to greet the second edition; for it continues to be the best general book we have on Ascomycete taxonomy. But is it the kind of book that leaves nothing to be desired? Certainly not. The following may seem, and probably will be considered by some, to be mere details, but I have yet to meet the author who would maintain that details do not matter. Date of publication. —... |

| Atlas van de Nederlandse bladmossen, door J. LANDWEHR, met medewerking van Dr. J. J. BARKMAN. Bibl. van de Kon. Ned. Natuurhistorische Ver., uitgave no. 15, Amsterdam, 1966, 504 p., 394 platen met ongeveer 4500 detailtekeningen, 38 figuren. Prijs ƒ 29.50 voor niet-leden en ƒ 24.50 voor leden van de K.N.N.V. Reeds lang bestaat bij de Nederlandse belangstellenden voor de mossenstudie de behoefte aan een boek met illustraties, dat naast de Mossentabel van Margadant kan worden gebruikt. Dank zij het lofwaardig initiatief en het doorzettingsvermogen van de heer Landwehr, en de medewerking van Dr. Barkman en de K.N.N.V. beschikken wij thans voor de bladmossen over zo’n plaatwerk. Zoals Barkman schrijft in zijn „ten geleide” is dit een uniek werk, dat de... |

| Habitu coloreque Mucronellae flavae Corner similis, ab hac tamen diversa subiculo manifesto, proventu caespitoso, sterigmatibus longioribus, sporis majoribus, cystidiis hymenialibus. Holotypus in GZU, fragmentum typi in L. Fungus resembling by its habit and colour Mucronella flava Corner, from which it differs in possessing a well-developed subiculum, caespitose growth, longer sterigmata, larger spores, and hymenial cystidia. |

| Some genera of Geoglossaceae, characterized by colourless spores and positive iodine reaction of the ascus pore, are compared with respect to the structure of the stipe. Ochroglossum is reduced to the synonymy of Microglossum. Mitrula is regarded as a monotypic genus. The generic name Heyderia is restored. Thuemenidium is reintroduced to replace Corynetes. Nothomitra is proposed as a new genus to accomodate N. cinnamomea, a new species. |

| The genus Tulostoma as occurring in the Netherlands is represented by T. brumale, T. melanocyclum, and T. fimbriatum. Practically all finds have been reported from the calciferous sands of the coastal area. A fourth species — T. squamosum — may be expected to occur in the extreme southeastern part of the country. A key to the species is given together with brief macroscopic descriptions which should help in the identification. Tulostoma melanocyclum, thus far unrecorded for the Netherlands, seems to be the commoner species. |

| 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”. |

| When revising the indigenous species of the genus Lecidea, I came across a case in which Körber’s Lecidella carpathica appeared to have been misunderstood. As the original description is insufficient for a good understanding of what its author had in hands, a redescription of the type specimen would not seem out of place. For the supply of some material for comparison my thanks are due to Dr R. Santesson, Uppsala. |
