Botanical collections in Slovak National Museum-Natural History Museum in Bratislava (acronym BRA) comprise cryptogams – i. e. non-vascular plants and fungi (including lichenized fungi), and vascular plants. The collection of cryptogams includes algae, bryophytes, lichens and fungi, fungal models and illustrations by A. Dermek, K. Cigánová, F. Procházka, J. Herink and freeze-dried fungi too. The collection of bryophytes includes specimens of renowned botanists (e.g. E.Bauer, Z. Pilous, V. Nábělek). Due to the long-term absence of a curator – bryologist, this group is currently unattended and not expanding. The lichenological collection, built and gathered by I. Pišút, is one of the largest and most well-known lichen collections in Central Europe in terms of quality and scope. P. Lizoň was dedicated to building an extensive mycological collection. This collection contains specimens of A. Kmeť, K. Kalchbrenner, F. Haszlinsky, J. Ľ. Holuby, V. Vraný, V. Greschik, and contemporary mycologists. The collection of vascular plants includes historical herbaria of Cyprián, A. Tagányi, M. Čulen, A. Kmeť, D. Sloboda, the reedition of Mattioli‘s herbarium, a sample book of grasses by I. Textorisová, botanical illustrations by K. Cigánová, the herbarium of M. Horváthová-Runkovičová and many important botanists and collectors. In addition, there is a collection of fruits and seeds, a large collection of archival materials, manuscripts and correspondence of prominent botanists (V. Greschik, S. Kupčok, G. Grodkovszky, J. Scheffer, E. Schidlay, J. Dvořák and V. Hodoval). The collection funds are expanded and supplemented every year. Key words: cryptogams, Herbarium BRA, Slovakia, Tracheophyta.
