Updates to the list of Estonian lichenized, lichenicolous and allied fungi
Sixteen species are reported as new for Estonia. Among these species, ten are lichenized and six are lichen-habiting fungi. One lichen-habiting species – Bryostigma molendoi (Heufl. ex Arnold) S.Y. Kondr. & Hur (= Arthonia molendoi (Heufl. ex Arnold) R. Sant.) and one lichenized species – Lecania nylanderiana A. Massal. should be excluded from the Estonian list of lichenized and allied fungi as misidentifications. New locality data are given for two critically endangered (CR) lichens last found more than 45 years ago – Hypogymnia vittata (Ach.) Parrique and Nephroma bellum (Spreng.) Tuck. (Lõhmus et al., 2019). Additional information on the distribution in Estonia is provided for recently described Toniniopsis separabilis (Nyl.) Gerasimova & A. Beck (Gerasimova et al., 2021).
