Observations on the anamorphs of six species ofDiatrypeandDiatrypella

摘要

Cultures and anamorphs of six species ofDiatrypeandDiatrypellaare described.Diatrypella favaceaproduces conidia from sympodially proliferating conidiogenous cells, whereasDiatrype stigmaproduces conidia from percurrently proliferating (annellated) conidiogenous cells. Both of these types of conidiogenous cell proliferation were found inDiatrypella verrucaeformis, Diatrypella pulvinata, Diatrype virescens, andDiatrype albopruinosa. Both the sympodial and percurrent modes of conidiogenous cell proliferation appear to be associated with holoblastic conidiogenesis.
