Résumé (anglais) : Lamprospora angularis sp. nov. is described and illustrated from finds in four different Tenerifan localities. The new species is characterised by a combination of the following features: orange to reddish-orange apothecia with a conspicuous fimbriate to shaggy margin, globose ascospores with distinctive regular areolate ornamentation, and infection of the rhizoids of its bryophyte host Campylopus pilifer. Phylogenetic analysis of SSU, LSU and EF1-α gene sequences show that the studied collections of this species form a well-supported monophyletic clade and clearly differ from all other sequenced species of bryophilous Pezizales. Comparisons have been made with similar members of Lamprospora that infect species of Campylopus, namely L. australis, L. campylopodis and L. verrucispora.
The Canary Islands are hotspots for biodiversity and contain many interesting and endemic species, including bryophytes (mosses, liverworts, and hornworts), and the fungi associated with them. The bryophilous Pezizales represent a relatively conspicuous group of ascomycetes frequently found on or beside bryophyte host patches in a variety of habitats though these fungi are under-studied outside of Central Europe […]
