Abstract: Octospora sulcatispora is described as a new species based on five collections from three different locations in Spain (Andalucía, Castilla y León and La Rioja). It is unique due to the sulcate ornamentation of its ascospores, a trait otherwise completely unknown in the bryophilous Pezizales. Furthermore, it is the first species of bryophilous Pezizales known to infect the moss Aschisma carniolicum from the family Pottiaceae. Phylogenetic analyses of the LSU, SSU, ITS, and EF1-α sequences showed that the collections of this new species form a well-supported monophyletic group and clearly differ from all other sequenced species of Octospora.
The study of the bryophilous Pezizales genera Octospora Hedwig, Lamprospora De Not., Neottiella (Cooke) Sacc., Octosporella Döbbeler, Filicupula Y.J. Yao & Spooner and Octosporopsis U. Lindemann & M. Vega has increased considerably in recent years (Eckstein et al., 2022; Janošík et al., 2023). This has primarily been at the European level, but more specific studies have considered the occurrence of bryophilous Pezizales in the Iberian Peninsula, the Balearic Islands and Macaronesia […]
