| With the death on 3 September 1995 of Dr. E. Kits van Waveren, the Dutch mycologists lost one of their most prominent, internationally known amateurs, a specialist on the taxonomy of the genus Psathyrella and an ardent collector. Dr. Kits van Waveren, honorary staff member of the Rijksherbarium at Leiden since 1970 and honorary member of the Dutch Mycological Society since 1983, will be most of all remembered as the author of the monograph ‘The Dutch, French and British species of Psathyrella’ published in 1985 as Supplement 2 of the mycological journal Persoonia. In this book of 300 pages about 100 species of Psathyrella are extensively described and illustrated, 10 of which were new to science. This publication, together with 7 later papers between 1986... |

| In the second and last part of this paper the genus Pseudobaeospora is redefined, its taxonomic position is discussed, and the possibilities of a formal infrageneric classification are considered. Because of the recent discovery of another new species, viz. P. mutabilis Adamčík & Bas, emendations of the key published in the first part of this paper (Bas, 2002), are proposed. Descriptions and drawings of all European taxa known are presented. Extralimital species are discussed and compared with European species. With the rapid increase in the number of species of the genus Pseudobaeospora in Europe from one or two ‘classical’ ones before 1995 to 14 to 16 species at present, also the morphological diversity of the genus has increased considerably.... |

| One of us (Bas, 1969: 436) described a mediterranean member of Amanita section Lepidella under the name A. gracilior, however, without validating this name because of scanty material and incomplete information on the fruit-bodies in fresh condition. Meanwhile, both the present authors have collected and extensively annotated this species, so that time has come to give it legal status. |

| Full descriptions of Agrocybe pusiola (Fr.) Heim and A. putaminum (Maire) Sing. are given. The following items may be stressed: (i). Pleurocystidia and cheilocystidia of both species appear to contain many nuclei when coloured with aceto-carmine. (ii). Agrocybe pusiola most probably has a gelatinized veil. (iii). Agaricus laevis Pers. is not conspecific with Agrocybe pusiola as was claimed by Fries. (iv). Agrocybe putaminum has, in addition to the normal pleurocystidia, a remarkable type of cystidia with yellowish contents. (v). The habitat of A. putaminum is not confined to fruit-stones. |

| Amanita grallipes, a new species from the State of Parand in southern Brazil, belonging to Amanita sect. Lepidella subsect. Vittadiniae, is extensively described and illustrated. It is well-characterized by a long, slightly rooting stipe with a non-bulbous base and scattered remnants of the universal veil, a dark brown pileus with dark brown warts, lamellae turning maize yellow, ellipsoid spores shorter than 9.5 µm and the presence of clamp-connections. |

| Eight species of Amanita from tropical lowland forests around Manaus, Brazil, are described, seven as new and one under a provisional name: A. campinaranae, A. coacta, A. craseoderma, A. crebresulcata, A. lanivolva, A. phaea nom. prov., A. sulcatissima, and A. xerocybe. Information is given on the types of Amanitopsis plumbea Rick and Collybia sulcatissima Rick, both remaining insufficiently known taxa. A very sketchy grouping of South American Amanitas on ecological grounds is discussed. |

| 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”. |

| With the death on 24 September 1986 of Drs. H.S.C. Huijsman the Dutch mycologists lost one of their ablest and internationally known fellow members as well as a rich source of agaricological information and inspiration. In the early beginning of his professional medical life as an oculist, Huijsman became spellbound by agarics and boleti and their wealth of taxonomical, morphological and biological problems. By dedicated studies in the field and at home with microscope and rapidly growing library, he soon became the leading agaricologist in the Netherlands. Frequently he put his increasing knowledge to the test at mycological forays abroad, particularly in France, where he got acquainted with several of the great mycologists as Maire, Heim, Konrad,... |

| Six species of Amanita (Amanitaceae, Basidiomycota, Fungi), collected in the Pakaraima Mountains of Guyana, are described; four as new and two as new records for Guyana: A. aurantiobrunnea spec, nov., A. calochroa spec, nov., A. cyanopus spec. nov., A. perphaea spec. nov., A. lanivolva Bas, and A. xerocybe Bas. All six species have been collected in forests dominated by Dicymbe (Caesalpiniaceae) and are assumed to be ectomycorrhizal. Amanita perphaea is commonly eaten by Patamona Indians and is called ‘Pulutukwe’. |

| A historical survey of the delineation of the genus Amanita and its infrageneric classification is given. Morphological and other characters of Amanita are discussed, with emphasis on the characters and the behaviour of the volva. The term ‘pileipellis’ is proposed to replace Fayod’s term ‘cuticula’. In the taxonomic part synonymy and descriptions are given of the genus Amanita and its subgenus Lepidella, together with a key to the subgenera and the sections. Section Lepidella is provisionally monographed on the base of exhaustive examinations of type material, as far as available, and a usually limited number of additional collections. Of the 93 species recognized, sixteen are described as new, and seven provisionally as new species; three new names and... |

| In 1965 the late Mr. J. Daams, an ardent and acute fungus collector, discovered in a greenhouse at ’s Graveland, the Netherlands, a baffling small agaric with a very dark red-brown pileus, dark brown (sub)decurrent lamellae, a whitish veil partly covering pileus and stipe and a bitter to even acrid taste. The microscopic characters soon revealed that a rather aberrant species of Galerina was involved. In later years this species has been repeatedly found in greenhouses, but also outdoors in orchards, in the same region, always on compost or blackish soil, but after 1971 it has not been recorded again. A recent scanning of the literature on Galerina has shown that none of the nearly 300 species of this genus recognized in the world combines the characters... |
