145(143) Perithecia hairy, globose, 350-500µm diam., stromatal strands up to 25mm long. Spores ellipsoid, flattened on one side, 9-12 × 6-8µm. _Wawelia octospora_ - Perithecia villose with conidiophores, globose, 230-420µm diam., produced laterally on stromatic filaments 20-30 × 0.1-0.3mm. Filaments pink at first, with a white pointed tip, becoming brown, velvety with conidiophores. Spores ellipsoid to flattened on one side, 7.5-9.5 × 3-4.5µm. _Wawelia_ sp. (fig. 37) [Illustration: FIG. 37. _Wawelia_ sp., stromatic filaments with perithecia growing from a rabbit pellet, ascospores, and conidiophore and conidia.] 146(141) Asci 8-spored. Spores 20-31 × 9.5-15µm. _Bombardioidea bombardioides_ - Asci 4-spored. 147 147(146) Spores 24-34 × 15-19(20)µm. Basal germ pore less distinct than the apical one. _Bombardioidea serignanensis_ - Spores 34-43 × 16-22µm. Distinct germ pore at each end of spore. _Bombardioidea stercoris_ 148 Fruit bodies solitary or in small groups, each a (key 1,1) subglobose, fertile, light brown head on a slender sterile stalk. Head soon bursting to expose the yellow ochraceous spore mass. On mixtures of bird droppings, cast pellets and decaying animal material. 149 - Fruit bodies superficial, lacking a distinct stalk. 150 149(148) Spores 5-8 × 2-3µm. Head 1-2mm diam. _Onygena corvina_ (fig. 38) - Spores 7-9 × 4-6µm, 4-5µm. Head 2-4mm diam. _Onygena equina_ 150(148) Fruit bodies with an external wall of loosely anastomosing and interwoven hyphae, and with ± specialised terminal cells (GYMNOTHECIA, fig. 39). 151 - Fruit bodies with a well defined parenchymatic wall (CLEISTOTHECIA, fig. 46). 161 151(150) Gymnothecia with simple thin-walled, ± uniform and poorly developed hyphae constituting the outer hyphal sheath. 152 - Gymnothecia with thick-walled hyphae modified at their ends into appendages, or if thin-walled then always accompanied by appendages (i.e. curled, toothed or pointed hyphae). 155 [Illustration: FIG. 38. _Onygena corvina_, habit sketch, ascus and ascospore.]
