I suspected that it was something along the lines of G. marginata after seeing the microscopy from other Asutralasian collections, but wasn’t sure whether we had any other species with similar features. I don’t have journal access any more so couldn’t check out Wood’s paper. Thanks again.

Well…

Well, looking at the paper “Studies in the Genus Galerina in Australia”, A. E. Wood… with the pleuro and cheilocystidia, and the roughened spores, it really looks like the best match is just G. marginata. With the pleurocystidia, and the stipe that is covered in off-white surface hyphae, these do look clearly to be in section Naucoriopsis. And in that section, in Austrailia in that paper, you don’t get too many choices. Without the branched cystidia on the ends, mostly you get G. marginata.

I checked these out under the scope and didn’t find any biforcate cheilocystidia so that rules out G. patagonica. I’m not sure what the microscopy does point to but maybe someone will know.
