XVI International Botanical Congess
Podostroma was described as a genus in the Hyupocreales 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 locationion the strom has not been well documeted 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.
