Lichen herbaria in The Netherlands
The Dutch lichen herbaria contain
about 261,000 specimens from all over the world. Most recent
herbaria are owned by the lichenologists themselves, whereas the
university herbaria (Nationaal
Herbarium Nederland) are not being
revised anymore after 1980, due to absence of lichenological
staff. The NHN herbaria are still very important for their
historical information, safety and continuity. Therefore, type
specimens of some species recently described species from the
Netherlands are stored in L. In addition to lichens, many
lichenicolous fungi have been collected in recent years are stored in private
The table below shows the number of specimens in the Dutch lichen herbaria
(all figures x 1,000).

The BLWG manages a
database with circa 500,000 field records from the
Netherlands (maps on
verspreidingsatlas.nl). The lichen herbarium
in Leiden (L) is currently being digitised by the curators, but
due to the use of old nomenclature a thorough revision of that
database and the related specimen labels will be necessary in
future. Recent epiphytic lichen monitoring data (> 1979) is
owned by several Dutch provinces (1,000,000 records).
Smaller herbaria are owned by e.g. B. Oving, P.
Eenshuistra (Venlo), R. Ketner-Oostra (Bennekom),
PWN/Hubert Kivit (Castricum), B. Torenbeek (Nuenen), D. Wolfskeel
(Schagen) and some provinces.
Curators of foreign herbaria with numerous specimens from Dutch origin are e.g.
F. Daniëls (Münster), P. Diederich (Luxembourg)
and H. Sipman (Berlin).
The KNBV, RIN,
WAG-W and AMS herbaria are
transferred to L. The lichens from herbarium V.
Westhoff are stored in ABL. The herbarium of A.K. Masselink (1940-1999) is
currently being revised by Dr. I. Masselink-Beltman and
will be transferred to L.
