Abstract

Zakeri, Z., Divakar, P. K. & Otte, V. 2017 Taxonomy and phylogeny of Aspiciliella, a resurrected genus of Megasporaceae, including the new species A. portosantana. — Herzogia 30: 166–176.

The genus Aspiciliella M.Choisy (type: A. intermutans) is resurrected to accommodate two species previously placed in Aspicilia, and a new species, A. portosantana Sipman & Zakeri. The new combination A. cupreoglauca (B.de Lesd.) Zakeri, Divakar & Otte is proposed. Molecular investigation based on three genetic markers, the nuclear ribosomal internal transcribed spacer 1, 5.8S and internal transcribed spacer 2 (ITS) region, the nuclear large subunit (nuLSU) and the mitochondrial small subunit (mtSSU) ribosomal DNA, of samples from a wide geographical range including Iran, Caucasia, Greece and Macaronesia revealed a strongly supported clade in a sister position to the other genera of the family Megasporaceae (PP = 1.00; MP/ML BS = 100/100). Morphological and chemotaxonomic surveys showed that the genus is characterized by a thallus that is crustose, rimose-areolate, partially continuous, K+ red; a green, olive-green to greenish-brown N+ light green epihymenium; 8-spored asci, ellipsoid, colourless, simple ascospores and very small (7–11μm long) conidia. An identification key to the species of the genus is provided.
