A new non-isidiate Leptogium species with transverse septate ascospores from Southeastern Brazil

Abstract

A non-isidiate Leptogium species with transverse septate ascospores is described as new. The species was collected in Serra da Mantiqueira and initially identified as L. megapotamicum; but the study of the type specimen demonstrated differences in the tissues of the apothecia; which supported the observed morphological variations of the thalli and apothecia found by our descriptive protocol.
