NOTES

Unlike mature stromata of S. moelleri, those of S. quisquiliarum have not been observed to bear synnematal remnants in nature. The synnemata of S. quisquiliarum in culture are fragile and those formed in nature probably deteriorate rapidly. Compared with the synnemata of S. moelleri that are produced in culture, those of S. quisquiliarum are composed of hyphae that are less compact.

Our decision to include this fungus in Stilbohypoxylon could be questioned, given the ephemeral nature of the synnemata compared with those of the other species. Colonies in nature and in culture, however, have a striking resemblance to S. moelleri, especially in their yellowish aspect and in the yellow perithecial scales. We are convinced that it is well-placed here.

Miller (1961) considered Hypoxylon quisquiliarum and H. rosellinioides to be distinct species. We have examined type materials of both names and several specimens identified as H. rosellinioides by Miller. They appear to be conspecific.
