Not Oudemansiella mucida based on pleurocystidia shape

The specimen had large, hyaline, globose spores and fusoid-ventricose pleurocystidia, so this is Oudemansiella and not a genus in the Agaricaceae. We did not examine the structure of the pileipellis, which is diagnostic for separating canarii and O. platensis. Oudemansiella mucida does have an annulus, so it resembles this, but the pleurocystidia are saccate (long-ovoid) in that species whereas the pleurocystidia in this specimen were fusoid. It could be either O. canarii or O. platensis, a neotropical species described from Argentina, or could be a new species.
