| About 40 collections of Pseudobaeospora species from all over Europe have been studied. A key is presented to the 13 species recognised and two provisionally defined ones. Latin diagnoses of six new species, one new variety and one new forma are given. Part one of this paper contains an introduction, a key to the taxa studied and Latin diagnoses of the new taxa. Part two will contain the description of the genus, full descriptions and figures of all taxa treated, and discussions. |

| 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.... |

| For several years now a very striking agaric is known to occur in the Netherlands that baffles every mycologist who has the luck to see it. As one of us (P.H.) never had this luck, the present study is based on thorough examinations of the material by the other author, while for the rather precarious taxonomic decisions both authors are to be held responsible. At first sight the present species resembles a large Agaricus bitorquis, but on closer examination the differences are obvious and manifold. There is however no doubt about the fact that it belongs to the Agaricaceae. It combines microscopical characters of the (sub)tropical genus Micropsalliota with a type of basidiocarp like that of the heaviest species of Agaricus. We think, however, that it... |

| 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. |

| The area of distribution of Amanita inaurata Seer, appears to fall almost completely within the Fluviatile district as distinguished by phanerogamists. There seems to be a number of other calciphilous species with a similar pattern of distribution. Others, however, occur in the Fluviatile district and at the same time along the inside of the calcareous coastal dunes. Also the latter pattern is well-known in phanerogams. In general the number of records in fungi is still too low for definite conclusions. |

| A few weeks ago a reprint was distributed of an interesting paper on the formation of spores by metamorphosis of basidia in fruiting bodies of Mycocalia and Scleroderma. That in itself was not so remarkable. But it is really a small miracle that this paper was written by Dr. A.F.M. Reijnders at the age of 99 and that it appeared in the outstanding international mycological journal ‘Mycological Research’ (1999). It may take another 100 years before a mycologist will equal this impressive performance. Mycology has much to thank Dr. Reijnders for. Soon after he started to publish mycological papers in 1930, his first work on the development of the fruiting body in Agaricales appeared (1933). This publication, in the Dutch language, is to be seen as an... |

| 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... |

| This special issue of Persoonia is dedicated to Dr. R. A. Maas Geesteranus who celebrated his 80th birthday on January the 20th 1991 in good health and spirits. Dr. Maas Geesteranus retired in 1976. On this occasion a biographical note and a list of his publications were published (Persoonia 8: 335-343. 1976). What only could be hoped then has fortunately come true: he intensively continued his excellent research in the taxonomy of macromycetes. In the last fifteen years an uninterrupted stream of more than 50 papers were published. |

| 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,... |

| 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... |

| 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... |
