. The fungi which cause plant disease . Plant diseases; Fungi. Fig. 107.—Cenangium, habit sketch, asci and paraphyses. After Tulasne. Conidia (= Brunchorstia destuens Erikss.) in pyc- nidia which are partially embedded in the host, the smaller simple, the larger compound, 1-2 mm. in diam.; spores 30-40 x 3 n, tapering-rounded at each end, 2 to 5-septate. A second conidial phase (=Dothichiza ferruginosa Sacc.) has simple spores. C. vitesia occurs in conidial form as Fuckelia on Ribes. In many Dermatea Fries (p. 151) A genus of over sixty species some of them parasitic species conidia in pycnidia are known. Ascocarps scattered or clustered, stromate, sessile or not, black or brown; asci small, thick- walled, 8 or 4-spored; spores el- lipsoid or spindleform, 1-celled, becoming 4 to 6-celled, brown, 2-ranked; paraphyses septate, api- cally enlarged and colored. D. carpinea (Pers.) Rehm. is a wound parasite on the horn- beam and beech; D. cinnamomea (Pers.) Rehm. on oaks; D. acerina Karst, on maple (Acer pseudo- platanus); all in Europe. D. pninastri (Pers.) Fr., with its conidial form Sphaeronema spurium Fr. is found on Bark of various species of Prunus, in Europe and America. Bulgaria Fries (p. 151) The gelatinous apothecium is rather large and dark colored; asci 4 to 8-spored; spores 1-celled, elongate, brown. There is one species worthy of mention.. Fig. 108.—Dermatea.
