AW: BRYONET: [spores or gemmae?]


Dear Maaike,

your objects are spores of fungi as Wolfgang told you. We find them often in
peat samples during pollen analyses. You can see pictures in several
publications of B. van Geel. There you can find pictures of other objects
which could be very useful for your work.

For instance:
Van Geel, B. (1972): Palynology of a section from the raised bog
"Wietmarscher Moor" with special reference to fungal remains. Acta Bot.
Neerl., 21: 261-284.
Van Geel, B. (1986): Application of fungal and algal remains and other
microfossils in palynological analyses. In: B.E. Berglund (Editor), Handbook
of Holocene Palaeoecology and palaeohydrology. Wiley, Chichester, pp.
Van Geel, B., Coope, G.R. and Van der Hammen, T. (1989): Palaeoecology and
stratigraphy of the lateglacial type section at Usselo (The Netherlands).
Review of Palaeobotany and Palynology, 60, 25-129.

Our samples are treated with KOH and subsequently acetolysed according to
Faegri and Iversen (1975). So the pictures are clearer and the cell walls
can be seen much better.

Best wishes und good luck
