Bryologisch verslag voorjaarsexcursie Chaam 30 april tot en met 2 mei 1993
H.M.H. van Melick & J.A.W. Nieuwkoop

4-19

During the spring field meeting 1993 the bryologically relatively unknown region south of Breda (North Brabant) has been investigated. Although 136 species of bryophytes have been found during the meeting, among these 14 red data list species, the area appeared to be a poor area for bryophytes. The find of Nardia insecta was the first record in The Netherlands.

Verslag najaarsexcursie Walcheren

35-44

During the autumn field meeting in 1986 the region of lake 'Veerse Meer' has been visited. Some sand plates which came above water level only since 1961, appeared to be rich places for bryophytes. The find of Helodium blandowii was the first record in our country during this century.

Lichenen en mossen op begraafplaatsen in en rond Zwolle

Seven graveyards in and around Zwolle (Prov. Overijssel) were examined for graves of lichenological or bryological importance. In total 71 lichens and 29 mosses were noted, all from graves and walls. Interesting records include saxicolous Lecanora horiza, Trapeliopsis flexuosa, Polyblastia albida, Sarcopyrenia gibba and Porpidia soredizodes with apothecia.

Het voorkomen van Rhytidiadelphus triquetrus, R. loreus en Thuidium tamariscinum in Nederland
B.F. van Tooren & M.J.H. Kortselius
|
51-60
|
Distribution maps of Rhytidiadelphus triquetrus, R. loreus en Thuidium tamariscinum in The Netherlands are presented. Rhytidiadelphus triquetrus has become a rare species in the pleistocene part of The Netherlands whereas the presence of this species seems to be more or less stable in coastal areas. However, even here the species has become less common although this is not apparent on maps based on a 5x5 km2 grid. Indirect effects of air pollution form a possible explanation for the reduced number of accounts, at least in coastal areas where scrub and tall grasses replaced the low vegetation in which R. triquetrus has its optimum. The occurrence of Rhytidiadelphus loreus and Thuidium tamariscinum did not change very much during the last decennia. However, in the center of The Netherlands recent accounts of both species are rather rare. This might be a result of a lack of bryological excursions to this area.

Thuidium tamariscinum in Friesland
J. Koopman & K. Meijer
|
61-66
|
A preliminary distribution map of Thuidium tamariscinum in Friesland is presented. This map has been based on a 1x1 km2 grid. During this project, which is still in progress, one plant with two sporophytes has been discovered; in this century this is the only Dutch record of fertile T. tamariscinum documented with a herbarium collection.
