Specimen notes
Public Note:
17th Fungal Foray of New Zealand; The tapering, pointed setae emerging from the peridium are simple, very dark, thick-walled, smooth and one celled \endash measuring between 75 and 100 µm in length. Pseudoparaphyses are abundant as are fertile asci. Asci are thick-walled (bitunicate) and contain ca 8 ascospores in a multiseriately arranged fascicle. Ascospores are cylindrically fusiform, often slightly curved and taper gradually to ca symmetrical, narrowly rounded ends. They are hyaline, smooth, with up to 14 to 15 (perhaps more) transverse septa and measure 52.5-70 X 6 µm (n=7), The ascospores of our specimen are broader than those of the A. scopulum described by Reblova & Barr [Sydowia 52: 258-285 (2000)] and slightly more septate, but are very similar in length and in their resemblance to curved ascospores in Fig. 7b of their article. The greater width is like that of A. minutum (Fuckel) Sacc., (5-)6-7(-7.5) µm which they describe as a closely related species with shorter 40-55(-63) µm, less-curved ascospores. Despite the greater width and more numerate septa of ascospores in our specimens, other features seem to favor A. scopulum.
