Internally these peritheciacontain numerous asci closely packed together, each ascus con-taining eight sporidia, of an elliptical shape, divided across thecentre into two cells, and known as Melanconis stilhostoma, one ofthe compound Sphaeriacei of which the Melanconium bore thenaked conidia, so that we have the same stroma yielding nakedstylospores, and afterwards sporidia enclosed in asci. Anendless variety might be adduced of ascosporous Sphaeriaceihaving also a preceding crop of stylospores on tlie samemycelium. Here we may cite two examples of another kind which aredescribed in another chapter. These are—the Mucors, whichbear erect fertile branches surmounted l)v inflated vesicles. 68 INTRODUCTION TO THE STUDY OF FUNGI containing spores and producing from the same myceliumbranches which conjugate and form a zygospore ; also Perono-spora, the branched carpophores of which sustain zoosporangia,and from the mycelium produce, sexually, resting spores oroospores. Dead box leaves are often to be met with bearing on theirunder surface little pink tufts of a delicate mould arising froma creeping mycelium. Sometimes the fertile hyphae are effused,and not tufted. The conidiophores are shortly branched, withthe branches in whorls, bearing at the tips of the branchletsrather spindle-shaped conidia, and then called Verticilliumh(xi. Subsequently from the same mycelium erect branchesform fertile threads, which are themselves sparingly branched,and bear at their apices small globose sporangia, each enclosingseveral minute gonidia. This condition is Mucor hyali
