A brief overview of the genus Septobasidium in Switzerland During field work, Stefan Blaser found Septobasidium cf orbiculare on hazel and Septobasidium quercinum on oak. A good reason to take a closer look at this genus. A (transient) heart in the distribution atlas In the SwissFungi distribution atlas, a heart can be found on the page of spruce needle cast (Lirula macrospora). The reason for this is not a love for this species, but a bias in the data.
