This specimen was growing isolated in an old concrete wall, now dilapidated and invaded by vegetation, which surrounds a property. When I saw it I was immediately reminded of a species that found a couple of months ago -Plectania rythidia. Both the macroscopic and microscopic features that I managed to get match with this species originating from Oceania: spores of ellipsoidal shape, as it streaked across, with an average size of 21.8 - 24.9 x 10.1 - 11.8 µm (Qe = 2.2, N=52), paraphyses very long and thin. Only habitat (at first sight) does not coincide, since I do not remember having seen nearby trees of the genus Eucalyptus with which this species is normally associated.
