1 Phylogeny of Erysiphe, Microsphaera, Uncinula (Erysipheae) and Cystotheca, Podosphaera, Sphaerotheca (Cystotheceae) inferred from rDNA ITS sequences - some taxonomic consequences U w e B r au n & S usu m u T akam atsu Abstract: B raun, U. & T akamatsu, S. 2000: Phylogeny of Erysiphe, Microsphaera, Uncinula (Erysipheae) and Cystotheca, Podosphaera, Sphaerotheca (Cystotheceae) inferred from rDNA ITS sequences - some taxonomic consequences. Schlechtendalia 4: 1-33. The very close relationship between the genera Erysiphe s.str. (= Erysiphe sect. Erysiphe), Microsphaera, and Uncinula, which are connected by numerous intermediate taxa, is strongly supported by light as well as scanning electron microscopical features and has recently been confirmed by examinations of nucleotide sequences of rDNA internal transcribed spacers (ITS). Erysiphe s.str. and Microsphaera did not group into separate monophyletic lineage, but formed several small mixed clusters. It turned out that the formation of branched ascoma appendages does not have any taxonomic value on generic level. Therefore, Microsphaera is reduced to synonymy with Erysiphe s.str., and the new combinations, which are necessary, are introduced. Uncinula spp. form a basal subclade of the Erysiphe s.str./Microsphaera (Pseudoidium) clade, but since some species of Erysiphe s.str. belong in this subclade, it is necessary to reduce Uncinula to synonymy with the latter genus, too. Erysiphe emend, is formally divided into sections for nonphylogenetical, but morphological groups of species, viz. Erysiphe sect. Erysiphe, E. sect. Microsphaera, and E. sect. Uncinula. Furthermore, examinations of nucleotide sequences of rDNA ITS regions of numerous taxa belonging to tribe Cystotheceae showed that Podosphaera and Sphaerotheca did not form separate monophyletic clades. Taxa of Sphaerotheca sect. Sphaerotheca and sect. Magnicellulatae grouped together with two different sets of Podosphaera spp. in two separate subclades of a single Podosphaera/Sphaerotheca clade. Based on these results and since Podosphaera and Sphaerotheca are morphologically only distinguished by having appendages which are branched and simple, respectively, it is proposed to merge the two genera. New combinations for Sphaerotheca spp. under Podosphaera are introduced. Podosphaera is formally divided into sections and subsections for non-phylogenetical, but morphological groups of species, viz. Podosphaera sect. Podosphaera, P. sect. Sphaerotheca subsect. Sphaerotheca, and subsect. Magnicellulatae. Furthermore, some changes of the classification of the Erysiphaceae are proposed. The following new combinations are introduced: Erysiphaceae tribe Cystotheceae subtribe Sawadaeinae, Erysiphaceae tribe Golovinomyceteae, Erysiphaceae tribe Golovinomyceteae subtribe Arthrocladiellinae and subtribe Neoerysiphinae. Zusammenfassung: B raun, U. & T akamatsu, S. 2000: Phylogeny of Erysiphe, Microsphaera, Uncinula (Erysipheae) and Cystotheca, Podosphaera, and Sphaerotheca (Cystotheceae) inferred from rDNA ITS sequences - some taxonomic consequences. Schlechtendalia 4: 1-33. Die enge Verwandtschaft zwischen den Gattungen Erysiphe s.str. (= Erysiphe Sektion Erysiphe), Microsphaera und Uncinula, die durch zahlreiche morphologisch untermediäre Taxa verbunden sind, wird stark durch licht- und elektronenmikroskopische Merkmale unterstützt und durch neue Untersu­ chungen der Nukleotidsequenzen der rDNA-ITS-Region bestätigt, da diese Gattungen nicht zu verschie­ denen monophyletischen Linien gehören. Erysiphe s.str. und Microsphaera bilden jedoch verschiedene kleine, gemischte Gruppen. Es hat sich herausgestellt, dass die Bildung verzweigter Fruchtkörperanhängsel keinen taxonomischen Wert auf Gattungsebene hat. Deshalb wird vorgeschlagen, Microsphaera als Sy­ nonym von Erysiphe zu betrachten. Die notwendigen Neukombinationen werden eingeführt. Uncinula- 2 Schlechtendalia 4 (2000) Arten bilden ein „Subclade” an der Basis des ,£rysiphe s.strJMicrosphaera (PseudoidiumyCladcs”. Da auch einige Erysiphe s.str.-Arten in dieses „Subclade” gehören, ist es notwendig, diese beiden Gattungen zu vereinigen. Erysiphe emend, wird formal in folgende morphologisch, aber nicht phylogenetisch be­ gründete Sektionen gegliedert: Erysiphe Sektion Erysiphe, E. Sektion Microsphaera und E. Sektion Uncinula. Untersuchungen von Nukleotidsequenzen ribosomaler DNA (ITS) zahlreicher Taxa der Cystotheceae zeig­ ten, dass Podosphaera und Sphaerotheca keine getrennten „Clades” bilden. Taxa von Sphaerotheca Sektion Sphaerotheca und Sektion Magnicellulatae bilden zusammen mit zwei verschiedenen Gruppen von Podosphaera-Axttn getrennte „Subclades”. Auf Grundlage dieser Befunde und da Podosphaeraund Sphaerotheca-Ait&n morphologisch nur durch verzweigte und einfache Fruchtkörperanhängsel un­ terschieden sind, wird vorgeschlagen, beide Gattungen zu vereinigen. Neukombinationen von Sphaerotheca-Arten unter Podosphaera werden eingeführt. Podosphaera wird formal in folgende mor­ phologisch, aber nicht phylogenetisch begründete Sektionen und Subsektionen gegliedert: Podosphaera Sektion Podosphaera, P Sektion Sphaerotheca Subsektion Sphaerotheca und Subsektion Magnicellulatae. Weiterhin werden einige Änderungen der Klassifizierung der Erysiphaceae vorgeschlagen. Folgende Kom­ binationen werden eingeführt: Erysiphaceae Tribus Cystotheceae Subtribus Sawadaeinae, Erysiphaceae Tribus Golovinomyceteae, Erysiphaceae Tribus Golovinomyceteae Subtribus Arthrocladiellinae und Subtribus Neoerysiphinae. Comprehensive examinations of nucleotide sequences of the rDNA ITS region of powdery mildew fungi have recently been carried out (T akamatsu et al. 1998,1999,2000; S aenz & T aylor 1999; M ori et al. 2000). The results of these studies provide numerous data for a better insight into phylogenetic relationships of powdery mildew genera. Based on these molecular data as well as new SEM examinations (C ook et al. 1997), it was possible to reassess the genus Erysiphe DC. s.lat. and to re-arrange the classification of the Erysiphaceae (B raun 1999). T akamatsu et al. (1999) examined the phylogenetic relationships between Erysiphe s.str., Microsphaera L6v., and Uncinula L6v., and T akamatsu et al. (2000) dealt with Cystotheca Berk. & M.A. Curtis, Podosphaera Kunze, and Sphaerotheca L6v. Some taxonomic consequences of these molecular studies are discussed in the present paper. 1. Erysiphe s.str., Microsphaera, and Uncinula Based on new SEM examinations as well as molecular data, B raun (1999) recognized Erysiphe s.str. (= Erysiphe sect. Erysiphe), the genus Golovinomyces (U. Braun) V.P. Gelyuta (= Erysiphe sect. Golovinomyces U. Braun), and introduced the new genus Neoerysiphe U. Braun (= Erysiphe sect. Galeopsidis U. Braun). Erysiphe s.str. is morphologically very close to Microsphaera and Uncinula and connected with these genera by numerous intermediate taxa (B raun 1987). The anamorphs of the three genera are uniform and belong in Oidium subgen. Pseudoidium Jacz. (C ook et al. 1997). A clear morphological differentiation between Erysiphe s.str. and Microsphaera is hardly possible. T akamatsu et al. (1999) carried out comprehensive examinations of nucleotide sequences of the rDNA ITS region of numerous species of the genera Erysiphe s.str. and Microsphaera and some Uncinula spp. The results of these studies have been well demonstrated (T akamatsu et al. 1999: Figs 1-2) and discussed in detail, and have been supported by molecular investigations recently carried out by S aenz & T aylor (1999). Erysiphe s.str. and Microsphaera did not group into separate monophyletic lineages, but the species of these genera formed several small, mixed clusters, which cannot be phylogenetically distinguished from each other (T akamatsu et al. 1998,1999). It turned out that the formation B raun, U. & T akamatsu, S . : Phylogeny o f Erysiphe, Microsphaera,Uncinula... 3 of branched ascoma appendages does not have any taxonomic value on generic level. Thus, it is not tenable to maintain M icrosphaera as a separate genus. The latter genus must be reduced to synonymy with Erysiphe s.str. B raun (1 987) described Medusosphaera Golovin & Gamalizk. in detail, and B raun ( 1999) briefly discussed the taxonomy of this genus. The anamorph belongs undoubtedly in Oidium subgen. Pseudoidium and the formation of short bristle-like secondary appendages is hardly tenable as feature on generic level, which could be demonstrated within U ncinula/ Uncinuliella by molecular examinations (T akamatsu et al. 1999). Hence, it is proposed to reduce M edusosphaera to synonymy with Erysiphe (incl. M icrosphaera ). The anamorphs of Uncinula belong in Oidium subgen. Pseudoidium , too, and Erysiphe s.str. and Uncinula are also connected by some intermediate taxa (B raun 1987). Uncinula spp. form a basal subclade of the p se u d o id iu m clade” of powdery mildews (S aenz & T aylor 1999; M ori et al. 2000), which is composed of Uncinula as well as some Erysiphe s.str. species, e.g., Erysiphe gracilis R.Y. Zheng & GQ. Chen, E. rodgersiae (Y. Nomura) U. Braun, and E. ulm ariae Desm. (S. Takamatsu, unpublished data). Hence, Uncinula cannot be maintained as a genus of it own. There are numerous M icrosphaera spp. with apically uncinate-circinate appendages which are only distinguished from Uncinula spp. by having dichotomous branchings of the appendages. But, based on molecular examinations, it turned out that the formation of branchings does not have any taxonomic value on generic level. B raun (1995) reduced Uncinuliella R.Y. Zheng & G.Q. Chen to synonymy with U ncinula. This treatment has been fully confirmed by molecular examinations of M ori et al. (2000). Hence, the latter genus is to be considered now as a synonym of Erysiphe. Bulbouncinula R.Y. Zheng & G.Q. Chen must be reduced to synonymy with Erysiphe (incl. Uncinula), too, since its anamorph belongs in Oidium subgen. Pseudoidium (K uo 1993). Uncinula septata E.S. Salmon must be excluded from the Pseudoidium lineage, since this species takes a position at the primitive base of the whole powdery mildew clade (M ori et al. 2000). This is somewhat surprising, but, on the other hand, there are various unrelated powdery mildew genera with similar teleomorphs and quite distinct anamorphs, e.g., Uncinula/Pleochaeta and Golovinomyces/Leveillula. It is possible that Uncinula septata has to be placed in a separate new genus, but to solve this problem it is necessary to find the anamorph of this species. W ada (1 9 8 9 ) described two-celled blastoconidia for U. septata, but this very unusual feature has not been confirmed yet. Brasiliomyces Viegas and Typhulochaeta S. Ito & Hara belong in the Pseudoidium lineage, too (M ori et al. 2000), but the two genera are tentatively maintained and not reduced to synonymy with Erysiphe emend. Additional examinations are necessary. Brasiliomyces trina (Harkn.) R.Y. Zheng, the only member of this genus which has been examined molecularly, differs from the type species in having two-spored asci and is the type species of Californiomyces U. Braun. It would be useful to include in molecular studies some additional species of the genera concerned, above all the type species of Brasiliomyces. E rysiphe DC. emend. U. Braun & S. Takamatsu (incl. B u lb om icrosphaera A.Q. Wang, B u lbouncinula R.Y. Zheng & G.Q. Chen, Furcouncinula Z.X. Chen, M edusosphaera Golovin & Gamalizk., M icrosphaera L6v., Setoerysiphe Y. Nomura, Uncinula Lev., and Uncinuliella R.Y. Zheng & GQ. Chen). Anamorph: Oidium subgen. Pseudoidium Jacz. 4 Schlechtendalia 4 (2000) Teleomorph: Ascomata subglobose to somewhat depressed, non to slightly dorsiventral, peridium multilayered, pigmented, dark; with appendages, simple, irregularly to dichotomously branched, apex straight or uncinate to circinate; pluriascal; asci (2-)3-8-spored. Type species: Erysiphe polygoni DC. Since the whole Pseudoidium clade and its subclades are composed of mixed groups of E rysiphe-, M icrosphaera-, and U ncinula- like species, there is no evidence for a phylogenetic division of Erysiphe emend, into smaller units. Uncinula-like taxa occur, for instance, in the basal Uncinula subclade as well as in a distinct group together with Erysiphe gracilis, Typhulochaeta japonica, and Brasiliomyces trina (M ori et al. 2000). Hence, a separation of Erysiphe emend, in subgeneric units, founded upon phylogenetic results, is not justified, but a formal division based on morphological differentiations of the ascoma appendages (morphological groups) is possible and seems to be desirable, above all for practical purposes. Names of species can be cited then in the following way: Erysiphe ( M icrosphaera ) alphitoides, Erysiphe ( Uncinula ) necator, etc. Therefore, it is proposed to divide the genus Erysiphe emend, into three morphological sections: (1) Erysiphe sect. Erysiphe [ascoma appendages mycelioid, simple or irregularly branched; comprising species of Erysiphe s.str. and Setoerysiphe ], (2) Erysiphe sect. M icrosphaera (L6v.) U. Braun & N. Shishkoff comb, et stat. nov. (Bas.: M icrosphaera L6v., Ann. Sci. Nat., Bot., 3 Ser., 15: 154 (381), 1851) [ascoma appendages apically dichotomously branched, sometimes with a second type of short appendages; com prising B ulbom icrosphaera, M icrosphaera s.str., and M edusosphaera ], (3) E rysiphe sect. U ncinula (L6v.) U. Braun & N. Shishkoff comb, et stat. nov. (Bas.: Uncinula Ldv., Ann. Sci. Nat., Bot., 3 Ser., 15: 151 (133), 1851) [ascoma appendages simple, rarely forked, more or less setiform, apex uncinate-circinate, sometimes with a second type of short appendages; comprising Bulbouncinula, Furcouncinula, Uncinula s.str., and Uncinuliella ]. The following list contains all names of M icrosphaera spp. and Uncinula spp. and the adequate denominations under Erysiphe. Most of these species have been fully described and illustrated in Braun's (1987, 1995) monographs of powdery mildews.

Cystotheca, Podosphaera, and Sphaerotheca The genera Cystotheca, Podosphaera, and Sphaerotheca are closely allied and connected by having uniform anamorphs with catenate conidia and fibrosin bodies as well as ascomata with a single, (6-)8-spored ascus (B raun 1987). Cystotheca differs from Podosphaera and Sphaerotheca in having special aerial hyphae and an ascoma wall composed of two layers that easily separate from each other. Sphaerotheca is only distinguished from Podosphaera by having fruitbodies with unbranched appendages, which is comparable with the differentiation between Erysiphe and Microsphaera. However, molecular examinations within the Cystotheca-Podosphaera-Sphaerotheca complex (tribe Cystotheceae), recently carried out by S aenz & T aylor (1999) and T akamatsu et al. (2000), showed that die differentiation of simple and dichotomously branched ascoma appendages in this group of taxa is also not suitable as taxonomic feature at generic rank. S aenz & T aylor (1999) demonstrated that Podosphaera and Sphaerotheca do not form distinct clades and concluded that all Sphaerotheca species could be changed to Podosphaera. T akamatsu et al. (2000) carried out comprehensive examinations, based on 30 taxa of Cystotheca, Podosphaera, and Sphaerotheca, and fully confirmed the results of S aenz & T aylor (1999). The hypothesis that Podosphaera and Sphaerotheca form separate monophyletic clades has been clearly rejected by the Kishino-Hasegawa test. Tribe Cystotheceae is characterized by having two distinct clades, viz. the Cystotheca clade and the Podosphaera-Sphaerotheca clade, which is separated into two subclades. One of these subclades is composed of Podosphaera clandestina, a member of Podosphaera sect. Podosphaera and some addi­ tional taxa, including Podosphaera leucotricha which is usually placed in Podosphaera sect. Tridactyla Homma ex U. Braun, and species of Sphaerotheca sect. Sphaerotheca. The second clade consists of Podosphaera tridactyla (Wallr.) de Bary, the type species of Podosphaera sect. Tridactyla, and some other taxa on hosts belonging to the genus Prunus and species of Sphaerotheca sect. M agnicellulatae U. Braun. Podosphaera spp. take a basal position in both subclades. Hence, it is not tenable to maintain the genus Sphaerotheca in the present way. Taxa of Sphaerotheca sect. Sphaerotheca and sect. M agnicellulatae have been derived from Podosphaera- like ancestors independently from each other and 26 Schlechtendalia 4 (2000) form an intricated complex which is hardly separable into smaller units on generic level. Therefore, it is proposed to reduced Sphaerotheca to synonymy with Podosphaera. The classical separation of Podosphaera into two sections is also not tenable. Additional examinations of the structure of the two subclades within the Podosphaera-Sphaerotheca clade are necessary. Sawadaea Miyabe spp. possess conidia with fibrosin bodies, too. Based on molecular examinations, the latter genus pertains to the „fibrosin lineage“ (M ori et al. 2000) and takes a basal position within the Cystotheca clade (T akamatsu et al. 1998). However, Sawadaea and Cystotheca spp. are separated and do not form mixed groups (M ori et al. 2000). Furthermore, species of Sawadaea are clearly distinguished from Cystotheca and Podosphaera (incl. Sphaerotheca ) spp. by having polyascal ascomata with distinct appendages and a different type of conidiophores and conidia, belonging in Oidium subgen. Octagoidium R.T.A. Cook et al. Hence, Sawadaea should be maintained as a separate genus. Podosphaera Kunze emend. U. Braun & S. Takamatsu (incl. Kokkalera Ponnappa, Sphaerotheca L6v.) Anamorph: Oidium subgen. Fibroidium R.T.A.

Tidskr. 60(3): 387 (1966). Notes: N. Shishkoff (Cornell University, Long Island Horticultural Research Laboratory, Riverhead, N.Y., USA) is engaged in comprehensive examinations o f Sphaerothecafusca s.lat. and allied taxa, including morphological, host range, mating, and inoculation studies. The results o f these examinations will be published elsewhere, but taxonomical and nomenclatural consequences are discussed here. Sphaerothecafusca sensu B raun (1987) has to be divided into two species which are differentiated by the size o f the ascomata and, above all, the diameter o f the thin-walled apical part o f the asci (oculus). S. fusca was described from France on Doronicum austriacum, but Doronicum spp. are known to be hosts o f both taxa. Since type material o f Erysiphefusca is not preserved, a neotypification is urgently necessary to establish the application o f this name. Sphaerotheca is very common on various Doronicum spp., and almost all collections belong to the taxon with small ascomata and asci with small oculi, whereas the taxon with large fruitbodies and large oculi is rare. Therefore, it is proposed to neotypify E.fusca with a collection o f the common Doronicum powdery mildew, so that Sphaerotheca erigerontis-canadensis (L 6v.) L. Junell must be reduced to synonymy with this species. Sphaerotheca xanthii (Castagne) L. Junell (= Podosphaera xanthii (Castagne) U. Braun & N. Shishkoff) is the correct name for the other taxon with large ascomata and asci with large oculi. Collections on Verbena spp. {Sphaerotheca verbenae Savul. & Negru) and cucurbits {Sphaerotheca cucurbitae (Jacz.) Z.Y. Zhao) are conspecific. Podosphaera fusca and P. xanthii seem to be biologically differentiated by being homothallic and heterothallic, respectively. Sphaerotheca fuliginea (Schltdl.: Fr.)

Mikrobiol. 140: 238 (1985). S. fuliginea var. sibirica is confined to Veronicastrum sibiricum and differs from S. fuliginea s.str. in having ascomata with smaller peridial cells (B raun 1987) and a conidial germination pattern which is close to the Pannosa-type (T akamatsu et al. 2000). These features strongly support the phylogenetic placement o f this taxon between Podosphaera sect. Tridactyla and Sphaerotheca sect. Magnicellulatae (T akamatsu et al. 2000). Based on these results, this taxon has to be excluded from P. fuliginea and should be considered as a separate species. Sphaerotheca gunnerae Havryl. & U. Braun: Podosphaera gunnerae (H avryl. & U.

The classification of the Erysiphaceae - additions and corrections B raun (1999) discussed the classification of the Erysiphaceae proposed by C ook et al. (1997) and introduced some corrections and alterations. The following changes are proposed to reflect results of new molecular examinations. Since Sawadaea belongs into the „Fibrosin lineage“ of powdery mildew fungi, it is not justified to maintain tribe Sawadaeae V.P. Gelyuta. Sawadaea should be referred to tribe Cystotheceae in a separate subtribe. A rthrocladiella Vassilkov, G olovinom yces (U. Braun) V.P. Gelyuta, and Neoerysiphe U. Braun form a separate clade („Euoidium lineage“, M ori et al. 2000) which is clearly distinct from the ,,?seudoidium clade“ by having catenate conidia. Therefore, these genera should be placed in a tribe of its own. Erysiphaceae tribe Cystotheceae subtribe Sawadaeinae (U. Braun) U. Braun & S. Takamatsu comb, nov.
