| Soon after the foundation of the Rijksherbarium in 1829 King Willem I of the Netherlands presented the herbarium of C. H. Persoon to this institute. The fungi in this famous herbarium, along with some other collections, among which the tropical fungi collected by F. W. Junghuhn and H. Zollinger, formed the basis for the mycological herbarium. But in the early period of the Rijksherbarium, owing to a shortage of funds and the absence of a curator for the cryptogams, the collections of fungi and lichens were badly neglected and remained in disorder for a long time. It was the third director of the Rijksherbarium, W. F. R. Suringar (director from 1871 to 1898) who became aware of the omissions in the collections of cryptogams and who took measures to fill the... |

| Surprisingly little is known about New Zealand’s fungi, of which many are believed to be unique to New Zealand. The authors estimate that about 2/3 of the expected 22,000 species are unrecorded. This first volume seeks to provide a foundation for understanding New Zealand’s fungi, including taxonomic, ecological, historical and cultural knowledge, along with inventories of recorded species. It is a cooperative initiative by several New Zealand mycologists and a Swiss mycologist (Horak). The next volumes will provide monographic treatments of selected taxonomic or ecological groups of fungi. The book starts with an abstract in English and Maori, and 16 coloured plates which illustrate some of the more conspicuous, colourful and distinctive species found in... |

| The structure of the top of the ascus in live Ascozonus woolhopensis has been studied by phase-contrast and interference-contrast microscopy, and by ordinary light microscopy after glutaraldehyde-OsO4-fixation. New information was obtained from stained 0.5 μm-sections of asci embedded in epoxy resin. Electron micrographs have been made of median sections of asci that were first fixed in 1.5% sodium permanganate and postfixed with osmium tetroxide. Light and electron microscopy have given concordant information on the organization of the top of the ascus in Ascozonus. In the ascoplasma no structures of an apical apparatus have been found. After meiosis the wall of the ascus consists of a broad, electron-transparent inner layer and a thin, electron-dense... |

| With the publication of volume 15 (1) Persoonia has undergone a number of changes, both in the team of managing editors and in the lay-out. Dr. C. Bas retired in March 1991 from his post at the Rijksherbarium, and turned over his editorial duties to his successor, Dr. M.E. Noordeloos, after finishing volume 14, part 4, the ‘Festschrift’ dedicated to Dr. R.A. Maas Geesteranus. Dr. Bas has been an editor of Persoonia since 1972, and the present editors wish to thank him most sincerely for his efforts to maintain and improve the standard of our journal. |

| The ultrastructure of the ascus and the ascospore wall of Eleutherascus lectardii, E. tuberculatus, E. peruvianus, Ascodesmis nigricans, and A. microscopica is studied and compared. Especially the development of the primary and the secondary spore walls is exactly the same in Eleutherascus and Ascodesmis. Eleutherascus is placed as an extremely simple fungus in the Ascodesmidaceae (Pezizales). |

| Genera that have been included in the family Thelebolaceae Eckblad are considered for the structure of the apical apparatuses of their asci. In the absence of such information, other characters could sometimes be used to clarify their most likely taxonomic position. The affinities of Cleistothelebolus, Coprobolus, Coprotiella, Dennisiopsis, Lasiobolidium, Lasiothelebolus, Leptokalpion, Mycoarctium, Ochotrichobolus, and Zukalina are discussed. The ultrastructure of ascus tops has been studied in Thelebolus microsporus, T. coemansii, T. caninus, T. crustaceus, T. polysporus, T. nanus, T. stercoreus, Caccobius minusculus, Lasiobolus pilosus, L. cuniculi, L. monascus, Ascozonus woolhopensis, A. solmslaubachii, Ramgea annulispora, Coprotus lacteus, and... |

| The present paper, which is the first of a series of studies on Discomycetes, is concerned with type material of Ascobolus and Saccobolus from Spegazzini's herbarium, deposited at La Plata (LPS). The author is indebted to Dr. J. C. Lindquist, for sending the herbarium specimens on loan. The work for this paper was facilitated by a grant from the Netherlands Organization for the Advancement of Pure Research (Z.W.O.). |
