Two new species of Sphaerophorus (Caliciales) from New Zealand

Abstract The new species Sphaerophorus whakapapaensis Wedin and S. ohlssonii Wedin (Sphaerophoraceae, Caliciales, lichenised ascomycetes) are described from New Zealand. The ascospore ontogeny is described. The spore ornamentation of both species consists of mazaedial material added to the spore wall after the spores have teen released from the asci. Concentric bodies occur in young ascospores. The conidiophores are branched and produce conidia both acrogenously and pleurogenoesly. The conidiophores thus correspond to Vobis' type V. The conidia are bacilliform in S. whakapapaensis and ellipsoidal in S. ohlssonii. The distribution of the species and their taxonomic position in the genus are commented upon.
