Specimen notes
Public Note:
Appears to fit Ameghiniella sensu Zhuang (1988), the excipular tissues appearing not to be particularly gelatinous when rehydrated (although the discs shrink dramatically when dried), and the outside of the receptacle is coarsely lumpy. Does not obviously key to anything in Zhuang. Lacks the gelatinous caps on the paraphyses of the Australian Ionomidotis australis. Could be the South American Ameghiniella australis, but the paraphyses of PDD 99209 are quite regular in shape, slightly swollen and usually gently curved, compared to the variably swollen and branched paraphyeses described by Gamundi & Romero (1998) for A. australis. PDD 99209 in places has phialide-like locules forming conidia on the outer excipular cells. Apothecium in tight group, about 25 mm across when fresh, appear to be thick-fleshed and highly gelatinous, when dry individual apothecia shrunken, 10 mm diam., cup-shpaed. Excipulum loosely tangled, thin-walled, pale brown hyphae 2-4 µm diam., outermost cells becoming swollen up to 8 µm diam. and arranged more or less perpendicular to margin of receptacle; paraphyses 1.5 µm diam, swelling suddenly to 2.5-3.5 µm diam. at apex, usually nodding or bent at apex, not gelatinous; asci 35-40 x 4-5 µm, J-, 8-spored; ascospores 6-7 x 1.5 µm, allantoid, hyaline.
