Description: Subiculum evanescent, extension restricted to stromata, chocolate brown, felty, covering completely young stromata, absent in mature material. Stromata (475)617 ± 99(750) µm high, (425)602 ± 78(675) µm wide (n = 10), subglobose to cupulate, brown when young, black at maturity, sometimes seated on a disk, solitary or 2-3 fused together, crowded, during development gradually emerging from the subiculum. Ostioles pointed to papillate. Ectostroma 25-50 µm thick, black. Entostroma brown. Perithecia detached in older material. Ascus apical rings (6.7)7.5 ± 0.5(8.1) µm high, upper and lower width 4.8-5.7 µm (n = 5), J+, dark blue. Ascospores (26)30.7 ± 2.6(36) µm long, (6.7)8.8 ± 0.6(10) µm wide (n = 60), inequilaterally ellipsoidal, often with pinched ends, brown to dark brown, with sigmoid germ slit about 2.3 of the spore length, both extremities and flat side surrounded by a slimy sheath.
Culture on OA cream-coloured, felty to velutinous, sterile.
Habitat: HOST: Macropiper excelsum.
MATRIX: Decorticated wood.
Notes: ETYMOLOGY: In honour of the New Zealand mycologist J. M. Dingley, who collected the type specimen and several other Rosellinia specimens deposited at PDD.
NOTES: Rosellinia dingleyae differs from R. chusqueae and R. franciscae by its larger ascospores (Fig. 9B). Ascospores of R. dingleyae have a shorter germ slit than those of R. chusqueae, but larger than that of ascospores of R. franciscae.
