New insights into Stilbocrea (Hypocreales, Bionectriaceae): recognition of S. colubrensis, a new species from Martinique (French West Indies), and observations on lifestyle and synnematous asexual mor

Abstract

Stilbocrea colubrensis sp. nov. is described and illustrated based on a collection on Bambusa vulgaris in Martinique. The placement of this species in Stilbocrea is supported by morphological characters and analysis of ITS and LSU sequences. This species differs from known species of Stilbocrea in having ascomata immersed in a prosenchymatous stroma composed of verrucose hyphae. In addition, morphological characteristics of synnemata of S. gracilipes and S. macrostoma are illustrated and discussed and S. macrostoma is shown to have only one type of synnemata
