In Persoonia 2: 389. 1962, the new combination Hydnellum piperatum (Coker) Maas G. was proposed, but it escaped my attention that the basionym, Sarcodon piperatus, had not been provided with a Latin description, rendering the new combination invalid. The following diagnosis, taken from Coker’s description and augmented with a few notes of my own, should validate the name.

Boekbesprekingen

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...

Clamp connections at the cheilocystidia in Mycena

Ano: 1967

URL: http://www.repository.naturalis.nl/record/527948

Clamp connections at the cheilocystidia in Mycena are invariably correlated with their presence in other elements of hymenium and subhymenium. In some species of the genus clamped cheilocystidia occur in both the four- and two-spored forms; in others, the cheilocystidia are clampless in the two-spored form. Two of the sections examined are shown to comprise species with clamped and species with clampless cheilocystidia, suggesting that the presence of clamps at the cheilocystidia is a character of specific rather than sectional importance. Two examples are given to illustrate the value of clamps at cheilocystidia as a distinguishing character Mycena jacobi and M. niveipes, long regarded as being identical, are here considered to represent two separate...

Corrections

Some bad errors crept into my work ‘Die terrestrischen Stachelpilze Europas’ and I am indebted to Dr. V. Demoulin, Liège, for having rapped my knuckles. Sarcodon regalis Maas G. in Verh. K. Ned.

De lange weg

Peziza alpina (Fuck.) Cooke (1876) and Peziza alpina (Fuck.) Oud. (1885) are recombinations based on Humaria alpina Fuck. (1874), and have no relation with Peziza alpina Sauter (1878). While the identity of Fuckel’s species is left out of consideration (as it will be discussed in a future paper), the fungus described by Oudemans appears to represent Cheilymenia coprinaria (Cooke) Boudier.

De Nederlandse Tulostoma-soorten

Ano: 1968

URL: http://www.repository.naturalis.nl/record/527707

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.

With the death of Dr. M. A. Donk on 2 September 1972 the mycological world has lost one of its great personalities. Born on 14 August 1908 at Situbondo, Java, of Dutch parents, Donk went to a secondary school at The Hague and entered the University of Utrecht in 1927. He received his doctor’s degree on 7 July 1933.

Further Mycenas from the State of Paraná, Brazil

Ano: 1973

Maas Geesteranus, R.A.; Meijer, A.A.R. De.

Seven new species of Mycena from the State of Paraná, Brazil, are described in section Sacchariferae, one species each in sections Nigrescentes and Granuliferae, and complementary notes are given of one species in section Polyadelphia. A key is provided for the species of section Sacchariferae thus far found in Paraná.

Further new species of Mycena and a new section from Spain

Villarreal, M.; Heykoop, M.; Esteve-Raventós, F.; Maas Geesteranus, R.A..

This short note directs the attention towards a new section and its type species, and two new species of section Fragilipedes (Fr.) Quél. Hydropus flocculinus is transferred to the genus Mycena.

Further new species of Mycena from Spain — II

Villarreal, M.; Heykoop, M.; Maas Geesteranus, R.A..

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.

Geoglossaceae of India and adjacent countries

Ano: 1999

URL: http://www.repository.naturalis.nl/record/531905

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.

Hyphal structures in Hydnums

In this paper descriptions are given of the hyphal structure in the hydnaceous genera Climacodon P. Karst., Creolophus P. Karst., Donkia Pilát, Hydnellum P. Karst., Mycoleptodonoides Nikol., Mycorrhaphium Maas G. (which is introduced as a new genus), Phellodon P. Karst., Sarcodon P. Karst., and Steccherinum S. F. Gray. The following new combinations are proposed: Hydnellum piperatum (Coker) Maas G., Mycorrhaphium adustum (Schw.) Maas G., M. pusillum (Brot. ex Fr.) Maas G., and Steccherinum murashkinskyi (Burt) Maas G.

Itinerary in Kenya colony and the union of South America

Ano: 1962

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.
