detail

Buerenia inundata: ascogenous spore

a single spore; the size amounted to 55-74 x 58-88 µm.

gall

Several mm sized bulges, mainly on the leaves; they change from whitish over yellowish to brown. In the tissue many, almost 0.1 mm large “spores” are formed, technically called ascogenous cells. In related genera the spores, after a resting stage, germinate and form a synascus, that is a bladder containing a number of asci that immediately loose their wall, leaving but a mass of ascospores. In Buerenia exceptionally there is no resting stage, and the synascus is formed within the spore.
