Rosellinia dingleyae L.E. Petrini 2003

ADDITIONAL SPECIMEN EXAMINED: NORTH ISLAND: NORTHLAND: Hokianga County, vic. Mangamuka Bridge, Mangamuka Gorge Track, on indet. wood, 14 Apr 1982, G. J. Samuels & P. R. Johnston, PDD 44329, culture on OA.
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.
HOST: Macropiper excelsum.
MATRIX: Decorticated wood.
Subiculum evanescens, circa stroma restrictum, badium, lanosum, primo stromata juvena omnino tegens, aetate provecta abest. Stromata (475)617 ± 99(750) µm alta, (425)602 ± 78(675) µm lata, subglobosa ad cupulata, brunnea dum juvena, nigra aetate provecta, interdum in disco insita, singularia ad 2-3 connata, conferta, paulatim e subiculo emergentia. Ostiola acuta ad papillata. Annulus apicalis asci (6.7)7.5 ± 0.5(8.1) µm altus, parte superiore et inferiore 4.8-5.7 µm latus, iodo valde coerulescenti. Ascosporae (26)30.7 ± 2.6(36) µm longae, (6.7)8.8 ± 0.6(10) µm latae, asymmetrice ellipsoideae, apicibus obtuso-acuminatis, brunneae ad atrobrunneae, fissura germinativa sigmoidea, duas e tribus partibus ascosporae totae recurrenti praeditae, utrisque apicibus et parte plana vagina mucosa circumdatae.
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.
HOLOTYPUS (hic designatus): New Zealand, North Island, Auckland: Piha, on Macropiper excelsum, J. M. Dingley, 17 Dec 1963, PDD 23199.
