Key 1. Ascomycota

1 Ascoma either globose to flask shaped, usually with an

easily observable pore or neck (PERITHECIUM or

PSEUDOTHECIUM, figs 16, 18, 19, 22, 27, 30, 32, 34-37),

or discoid (APOTHECIUM, figs 1, 3, 4, 7, 11-14). Spores

usually 8 in each ascus (less frequently 4, 16, 32, 64,

128 etc.). Asci ellipsoid to cylindrical, borne in a

distinct hymenium, thus appearing in fascicles or

distinct groups when the fruit body is squashed. 2

- Ascoma globose to subglobose, lacking a definite pore

or neck (CLEISTOTHECIUM or GYMNOTHECIUM, figs 38, 39,

46). Asci globose to subglobose, 8-spored, not in a

distinct hymenium, appearing quite free when the fruit body

is squashed. KEY 2, 148 (p. 45)

2(1) Ascoma a PERITHECIUM or PSEUDOTHECIUM, usually dark in

some part, not opening to a disc but remaining globose

or flask shaped. Asci unitunicate, not operculate but

often with an apical pore, which may stain blue in

iodine, or bitunicate. KEY 2, 1 (p. 24)
