Reijnders, centenarian
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.

Studies in Coprinus V – Coprinus section Coprinus, revision of subsection Lanatuli Sing.
A key is given to the species of subsection Lanatuli known from the Netherlands or to be expected in the Netherlands on account of records from neighbouring countries. For a key to the subsections in Coprinus section Coprinus see Uljé & Noordel., Persoonia 16 (1997) 267. Coprinus bicornis and C. spelaiophilus are described as new species. In addition the following species are fully described: C. ammophilae, C. calosporus, C. cinereus, C. erythrocephalus, C. geesterani, C. jonesii, C. krieglsteineri, C. lagopus, C. macrocephalus, C. ochraceolanatus, C. pachydermus, C. pseudoradiatus, C. radiatus and C. scobicola.

Type specimen studies in Pleurotus
An epitype specimen is designated for Pleurotus cornucopiae. Morphological examination of Mexican material and the type specimen of P. opuntiae showed that the distribution of this species includes North Africa and the highlands of Mexico. The type specimen of Lentinus (Pleurotus) eugrammus reveals that Singer based his proposal of Nothopanus on a mistaken interpretation of L. eugrammus, and that the concept of Nothopanus requires a new name and type species. Neonothopanus is proposed to solve this problem. Morphological reports are supplemented with data on mating systems.

Notulae ad Floram agaricinam neerlandicam XXXIII – Notes on Agaricus section Spissicaules
The subsection Spissicaules of Agaricus section Sanguinolenti is raised to section level. It is mainly characterised by the simple annulus, the presence of yellowing rhizomorphs, yellow discolouration of the context or surface at the base of the stipe and a positive Schaeffer-reaction, and the slightly reddening context in the higher part of the stipe. Section Spissicaules comprises three species in the Netherlands, viz. Agaricus lanipes, A. litoralis, and A. bresadolanus. Both A. maskae and A. spissicaulis are considered synonymous with A. litoralis; A. romagnesii is regarded as conspecific with A. bresadolanus. A new species is described from the Netherlands and Great Britain, A. rufotegulis, which is tentatively placed in subgenus Lanagaricus on account of the covering of the pileus and stipe.

Further new species of Mycena from Spain – II
In this paper, again, three new species of section Fragilipedes are described, Mycena olivaceoflava, M. rubidofusca and M. vicina. Mycena hepatica is a new species of section Rubromarginatae. The circumscription of section Insignes is slightly altered, as a result of which Mycena quinaultensis, M. conspersa, M. mitis and M. corrugans are transferred to section Fragilipedes.

Notulae ad Floram agaricinam neerlandicam XXXIV – Further notes on Psilocybe
A key to the species is given of Psilocybe subgenus Stercophila (Romagn.) Noordel., with a full description of Psilocybe dorsipora, new to the Netherlands, and the status of subgenus Stercophila is discussed. Within subgenus Hypholoma section Psilocyboides four new subsections are presented, viz. subsect. Elongatae, subsect. Marginatae, subsect. Tuberosae, and subsect. Ericaeae. A key is given to the species of subsect. Elongatae, with comments on the species and full descriptions of Psilocybe olivaceotincta Kauffm., new to Europe, and a still unnamed dark-coloured species. New combinations within subgen. Stropharia and Melanotus are given.

Notes on type materials of Tulostoma (Tulostomataceae),T. macrosporum, T. meridionale and T. utahense
A study of the macroscopic and microscopic characters of type materials of Tulostoma macrosporum, T. meridionale and T. utahense is presented. The synonymy of the two latter species, that was proposed some years ago, is now verified. Tulostoma macrosporum is very close to them, but shows enough differential features to be maintained as an autonomous species. SEM photographs of the spore ornamentation are provided.

A new species of Boubovia (Pezizales) from the Hvaler Archipelago in Norway
Boubovia vermiphila spec. nov. (Pezizales) is described from the mycologically interesting Hvaler archipelago in southern Norway, occurring on casts of earthworms. The relationship with Pulvinula and Boubovia luteola is discussed. Some distinctive characters between Pulvinula and Boubovia are considered.

Contributions towards a monograph of Phoma (Coelomycetes) III – Supplement. Additional species of section Plenodomus
This supplement deals with the diagnostic characteristics and literature data of three species of Phoma sect. Plenodomus: Phoma korfii spec. nov. (synanamorph Sclerotium orobanches Schwein.: Fr.), Phoma pimpinellae spec. nov. (teleomorph Leptosphaeria pimpinellae Lowen & Sivan.) and Phoma etheridgei L.J. Hutchison & Y. Hirats. (only known from isolates). They are filed into the key of section Plenodomus and the indices of the section are supplemented.

Contributions towards a monograph of Phoma (Coelomycetes) IV – Supplement. An addition to section Heterospora: Phoma schneiderae spec. nov., synanamorph Stagonosporopsis lupini (Boerema & R. Schneid.) comb. nov.
Study in vivo and in vitro of the ‘Ascochyta’-pathogen of lupin, indigenous to America, showed its conidial dimorphism. The phomoid phenotype developing in vitro and sometimes also in vivo is described as a new species of Phoma sect. Heterospora. The ascochytoid-stagonosporoid phenotype commonly occurring in association with disease symptoms is transferred to Stagonosporopsis.

Amanita dryophila (Amanitaceae) spec. nov. and the species of the section Vaginatae with a semifriable universal veil and ellipsoid spores
Amanita dryophila spec. nov. is described. The differential features of the new species with respect to A. beckeri as well as its delimitation from the other species of the section Vaginatae with a semifriable universal veil and ellipsoid spores are discussed.

Notulae ad Floram agaricinam neerlandicam XXXV – On the typification of Lactarius necator
Lactarius necator is neotypified with a collection from Sweden that fits well with the sanctioning description. The plate of Bulliard representing the original concept of Agaricus necator, is excluded from the type diagnosis. It is demonstrated that A. plumbeus is not conspecific with A. necator, and the alternative use of the name Lactarius plumbeus (Bull.: Fr.) Gray, as recently proposed by Heilmann-Clausen et al. (1998) is rejected.

Notulae ad Floram agaricinam neerlandicam XXXVI – Tricholoma
The genus Tricholoma contains several taxonomically difficult groups. During the revision of the genus Tricholoma for the Flora agaricina neerlandica, vol. 4 (Bas et al., in press) some of these groups have been tackled. Detailed studies are presented of sect. Lasciva and sect. Atrosquamosa subsect. Terrea with keys, descriptions, and comments. Where possible neotypes or epitypes have been designated. In addition two new varieties are described in other sections, viz. Tricholoma psammopus var. macrosporum and T. equestre var. populinum. Notes are given on some nomenclatural problems within the genus Tricholoma.
