“…Another fungus found on the type specimen of Meliola balsamicola Peck, and indeed taken by Hahn (1947) to be its juvenile form, was recently described and illustrated by Farr (1963) under "a new asterinaceous fungus" related to Asterina or Clypeolella. Farr did not feel that the specimens at her disposal were sufficiently mature to allow accurate determination of the fungus.…”

“…sp." This state of affairs, complicated further by the presence of other organisms on the type material, led to a proliferation of literature on the subject and resulted in much confusion (see Hahn 1947;Farr 1963). In 1965 Shoemaker showed that M. balsamicola is based on two fungi : Dimerium balsamicola (Peck) Shoem.…”

“…This mistake would account for her treatment of Dimerosporiz~m abietis as a synonym of Dimeriella balsamicola. The inclusion of three additional species as synonyms (Farr 1963) does not seem to be warranted. The main distinctions for the recognition of four congeneric species are given in the key.…”

“…Rather unexpectedly, a portion oi the type of Dimeriella balsamicola (Peck) Petrak mas found in the Dearness Herbarium. Exalnination of it and other critical specimens supported a different taxonomic treatnlellt from that put forxvard recently (Farr 1963). The results are given below, preceded by a key that outlines the n u i n macroscopic and lnicroscopic distinctions of the species treated.…”

Study of the type of Di~nerospoii~rnz balsa?nicola (Peck) Ell. I% Ex-. ( = illcliola balsa~~zicola Peck) revealed that this species is a lnelioline hyperparasite. The fungus is transferred to Dinzerizlvz, redescribed, illustrated, and distinguished from Phacoc,,yptopzls nzrdzls (Peck) Petralc, Asterigza sp., and from Epipolaeum abietis (Dearness) n. comb. ( = Di,nerosporiunz abielis Dearness), which also occur on Abzes i n North America. In all, four species of Epipolae~r~iz that occur on conifer needles are treated: Epipolaezl?lz abzetis on Abies grandis (Dougl.) Lindl. and Abies a~nabilis (Dougl.) Forb. in western North America, on Abies alba Mill. in France, and on Iielel~eria davidiana Beiss. in Formosa; Epipolaeum tsugae (Dearness) n. comb. on Tszrga canadensis (L.) Carr. in eastern Nortli An~erica, and on Tszlga helerophylla (12af.) Sarg. and Tszrga rnert~nsiana (Bong.) Carr. in western North America; Epipolaeurn pseudotsugae (V. M . Miller & Bonar) n. comb. on Psezldotszlga talifolia (Poir.) Britton from western Nortli America; Epipolaeum terrieri (Petrak in Terrier) 11. comb. on Abies alba in Switzerland.

The Mycosphaerellaceae represent thousands of fungal species that are associated with diseases on a wide range of plant hosts. Understanding and stabilising the taxonomy of genera and species of Mycosphaerellaceae is therefore of the utmost importance given their impact on agriculture, horticulture and forestry. Based on previous molecular studies, several phylogenetic and morphologically distinct genera within the Mycosphaerellaceae have been delimited. In this study a multigene phylogenetic analysis (LSU, ITS and rpb2) was performed based on 415 isolates representing 297 taxa and incorporating ex-type strains where available. The main aim of this study was to resolve the phylogenetic relationships among the genera currently recognised within the family, and to clarify the position of the cercosporoid fungi among them. Based on these results many well-known genera are shown to be paraphyletic, with several synapomorphic characters that have evolved more than once within the family. As a consequence, several old generic names including Cercosporidium, Fulvia, Mycovellosiella, Phaeoramularia and Raghnildiana are resurrected, and 32 additional genera are described as new. Based on phylogenetic data 120 genera are now accepted within the family, but many currently accepted cercosporoid genera still remain unresolved pending fresh collections and DNA data. The present study provides a phylogenetic framework for future taxonomic work within the Mycosphaerellaceae.
