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 reddishorange 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.
