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) - Ascoma an APOTHECIUM, white or lightly coloured, soft fleshed, opening out to a disc or cushion shape when mature. Asci unitunicate. 3 3(2) Asci opening by an operculum (fig. 8), a bilabiate vertical split down to a subapical ring of thickening (fig. 15), or apparently just bursting. 4 - Asci inoperculate, with an apical pore. 96
