Bart Horvers is a Dutch field researcher and nature photographer from the Tilburg region, specialising in myxomycetes (slime moulds) and coniocarps. A founding member of the fungi and lichen working group of KNNV Tilburg, he intensified his focus on slime moulds after 2016 - organisms that sit taxonomically between fungi and amoebae. In July 2021 he discovered three species new to the Netherlands in the forests around Oisterwijk and Tilburg. Together with Klaas van Dort he co-authored the bilingual reference work 'Coniocarpen, regenschaduwspecialisten' (2022), which attracted international attention.
Bart Horvers gives a lecture on myxomycetes and coniocarpous fungi in September 2026 at De Nieuwe Burght in Oisterwijk.
The book 'Coniocarpous fungi, rain shadow specialists' by Horvers and Van Dort was reviewed in the international journal 'The Lichenologist' by Cambridge University Press.
Horvers gave a lecture on coniocarpous fungi and slime moulds for IVN De Waerdman in Waalwijk.
The bilingual book 'Coniocarpous fungi, rain shadow specialists', written by Klaas van Dort and Bart Horvers, was published on 15 January 2022.
KNNV published the research report in which Horvers' discovery of three slime mould species new to the Netherlands in July 2021 was documented.
