Abstract
Lamprospora sylvatica is described as a new species based on finds from Ukraine, Slovakia, Germany and Norway. It is characterised by the combination of the following features: pinkish, orange to reddish-orange apothecia with a fimbriate margin, globose ascospores with more or less regular areolate ornamentation, infecting strong rhizoids of Dicranummontanum with an infectious structure consisting of a one-celled appressorium surrounded by a multi-layered cluster of thick-walled cells and haustorium within the rhizoids. The apothecia were always found on rotten wood, which is an unusual habitat for hosts of bryophilous Pezizales. The new species is compared to similar taxa morphologically and by means of DNA sequencing. In the phylogenetic analysis based on LSU and ITS regions, L. sylvatica forms a well-supported clade close to L. feurichiana (on Ceratodonpurpureus), L. kristiansenii (also on C. purpureus) and L. campylopodis (on Campylopus spp.).
