64(62) Spores 14.5-16 × 8-9µm, epispore lines not densely crowded. _Ascobolus cervinus_ - Spores smaller, epispore with densely crowded, rarely anastomosing cracks. 65 65(64) Apothecia greenish yellow, furfuraceous, with crenulate margin. Spores 9.5-15 × 6-8µm. _Ascobolus crenulatus_ (fig. 9) - Apothecia brownish yellow to brown, smooth, with undifferentiated margin. Spores 12.5-14.5 × 7-8.5µm. _Ascobolus minutus_ 66(45) Asci 4-spored. Spore clusters 42-58 × 14-20µm. Spores 16.5-23 × 9.5-12µm, smooth to finely punctate, but with a thick cap or girdle of reticulated or warted pigment. _Saccobolus quadrisporus_ - Asci 8-spored. 67 67(66) Spore clusters ± globular, 17-26(39) × 15-20µm. 68 - Spore clusters elongated, 2-3 times as long as wide. 69 68(67) Spore clusters compact, subglobose, with only the exposed surface of spores pigmented, ornamented with small and coarse warts. _Saccobolus dilutellus_ - Spores loosely united in cluster, ornamented with small isolated warts covering most of their surface. _Saccobolus globuliferellus_ 69(67) Apothecia yellow. Spores in 4 rows of 2 longitudinally arranged spores (fig. 10). 70 - Apothecia hyaline or violaceous (some mature darker). Spores in 2 rows of 3 and 1 row of 2 (fig. 10). 73 70(69) Spore clusters 40µm or longer. 71 - Spore clusters up to 40µm long. 72 71(70) Spore clusters 50-71 × 16-25µm. Spores 22-29 × 8.5-14.5µm, smooth or rarely finely punctate, with distant irregular cracks. _Saccobolus glaber_ (fig. 10) - Spore clusters 43-51 × 14-17µm. Spores 16-22 × 7.5-9µm, with fine isolated warts. _Saccobolus citrinus_ 72(70) Spores 14-17.5(19.5) × 7.5-8.5(10)µm, easily separated at maturity. Spore clusters becoming shorter and more rounded with maturity. Apothecia up to 300µm diam., inconspicuous due to their solitary nature and the predominantly brownish colour due to the mature spores. _Saccobolus truncatus_ (fig. 10) - Spores 11.5-13.5 × 5.5-6.5µm. _Saccobolus minimus_
