Euryachora the stroma is broadly effused and punctulate, whilst in Homostegia the stroma is plane or hemispherical, and the species are parasitic upon Lichens. In Rlwpographus the stroma is elongated and linear, suggesting a resem- blance to some Hysteriaceous perithecia. Species of Phyl- lachora are common on cori- aceous leaves in tropical coun- tries, and are sometimes difficult to distinguish at first from some of the Rhy- tismoideae. In common with the latter the stroma is often present for some time before the fructification is developed, hence they are often met with in a sterile condition. The subfamily Rhytis- moideae is included by some authors with the Discomyceteae, on account of the mode of dehiscence, which is usually by gaping fissures, so that the hymenium is more or less exposed; but this dehiscence does not take place until the sporidia are fully mature, and sometimes not until disintegration has commenced. In external appearance the species are very similar to Phyllachora and Eury- achora, and yet in texture of the stroma, and often in the fructification, appear to be more closely allied to the Dothideaceae than to any family of the Discomyceteae. Practically, the only genus is Rhytisma, for the sporidia of so many described species are unknown that no proposals have been possible to divide them into genera based upon the fructifi- cation. Such a species as Rhytisma acerinum, which is common Fig. 97.—Daldinia, globose stroma and section. Oard. Fig. Hypoxylon. sporidia. Globose stroma of with asoi and.
