Lichen Index

Here an ascus is shown with a full compliment of 8 elongated needle-like spores, each of which are multi-septate. The ascus tip stains blue with certain preparations. When thin sectioned, asci of this genus separate easily and are clearly visible. This is not always the case with many other lichens. Frequently, various methods have to be used to coax asci into the open.
