XVI International Botanical Congess
Podostroma was described as a genus in the Hypocreales having ascospore characters of Hypocrea, i.e. bicellular ascospores that disarticulate at the septum, but differing from the type species, H. rufa, in having a club-shaped or stalked stroma. The generic limits of Podostroma defy definition given that stroma morphology is the only distinguishing character. The stroma of the type species, P. alutacea, is a simple, erect club in which perithecia are embedded. The variation in depth to which perithecia are embedded and their location on the stroma has not been well-documented for P. alutacea . The anamorphs of Podostroma are Trichoderma, as in typical Hypocrea. Morphometric analysis will be conducted to more clearly define the relationship of P. alutacea to Hypocrea rufa.
