Boerema, G.H.; Gruyter, J. de.

This supplement deals with the diagnostic characteristics and literature data of three species of Phoma sect. Plenodomus: Phoma korfii spec. nov. (synanamorph Sclerotium orobanches Schwein.: Fr.), Phoma pimpinellae spec. nov. (teleomorph Leptosphaeria pimpinellae Lowen & Sivan.) and Phoma etheridgei L.J. Hutchison & Y. Hirats. (only known from isolates). They are filed into the key of section Plenodomus and the indices of the section are supplemented.

Phoma Piskorzii (Petrak) comb. nov., the anamorph of Leptosphaeria acuta (Fuckel) P. Karst

Ano: 1999

URL: http://www.repository.naturalis.nl/record/532354

Boerema, G.H.; Loerakker, W.M..

The pycnidial state of Leptosphaeria acuta appeared to be identical with the lectotype of Diploplenodomus piskorzii, and belongs to Phoma sect. Plenodomus. The binomials Phoma acuta, Leptophoma acuta and Plenodomus acuta are misapplied ambiguous names often referring to the anamorph of Leptosphaeria doliolum sensu stricto.

Contributions towards a monograph of Phoma (Coelomycetes) VI — 2. Section Phyllostictoides: Outline of its taxa

Ano: 1981

URL: http://www.repository.naturalis.nl/record/531923

Gruyter, J. de; Boerema, G.H.; Aa, H.A. van der.

Thirty taxa in Phoma sect. Phyllostictoides, characterised by secondary septation of a variable number of conidia, are described in vitro. Two Phyllostictoides-like species are (re)classified in sect. Sclerophomella on account of certain pycnidial characteristics. Short notes on the ecology and distribution are added. Newly proposed taxa are: Phoma acetosellae (A. L. Sm. & Ramsb.) Aa & Boerema comb, nov., Phoma argillacea (Bres.) Aa & Boerema comb. nov. (teleomorph Didymella applanata (Niessl) Sacc.), Phoma nepeticola (Melnik) Dorenb. & de Gruyter comb, nov. (teleomorph Didymella catariae (Cooke & Ellis) Sacc.), Phoma destructiva var. diversispora de Gruyter & Boerema var. nov., Phoma heliopsidis (H.C. Greene) Aa & Boerema comb,...

Remarks on species of Phoma referred to Peyronellaea—II

Boerema, G.H.; Dorenbosch, M.M.J.; Kesteren, H.A. van.

Additional data are given on Phoma glomerata (Cda.) Wr. & Hochapf., Phoma prunicola (Opiz) Wr. & Hochapf., and Phoma jolyana Pirozynski & Morgan-Jones. The new combination Phoma indianensis (Deshpande & Mantri) is proposed and its characteristics and habitat are discussed.

Phoma exigua Desm. and its varieties

Ano: 1968

URL: http://www.repository.naturalis.nl/record/531639

Boerema, G.H.; Höweler, Louise H..

Because of its growth features in vitro, pathogenicity and host relation, together with the ubiquitous wound- and weak-parasitic strains of Phoma exigua Desm. var. exigua, three more specialized pathogenic varieties of this species are distinguished: var. linicola (Naoum. & Vass.) Maas on flax, var. foveata (Foister) Boerema on potato, and var. sambuci-nigrae (Sacc.) comb. nov. on elder. The synonymy and the collective and differential diagnostic characteristics are discussed.

Contributions towards a monograph of Phoma (Coelomycetes) — IV. Section Heterospora: Taxa with large sized conidial dimorphs, in vivo sometimes as Stagonosporopsis synanamorphs

Ano: 1967

URL: http://www.repository.naturalis.nl/record/532159

Boerema, G.H.; Gruyter, J. de; Noordeloos, M.E..

The new section Heterospora is proposed for Phoma species producing not only relatively small, mainly aseptate conidia, but also distinctly larger conidia, which may become 1- or more septate: ‘ascochytoid-stagonosporoid’. The majority of the conidia are always phomoid in vitro, but in vivo they may be predominantly large and septate, synanamorphs being therefore referred to Stagonosporopsis Died. The heterosporous species are described in vitro, with additional data on the conidial morphology in vivo. An addendum deals with eight species from other sections which display a similar conidial dimorphism. Five new species and four new combinations have been proposed: Phoma actaeae spec. nov., Phoma alectorolophi spec. nov., Phoma nigripycnidia spec. nov.,...

Contributions towards a monograph of Phoma (Coelomycetes) — III. 2. Misapplications of the type species name and the generic synonyms of section Plenodomus (Excluded species)

Ano: 1997

URL: http://www.repository.naturalis.nl/record/532060

Boerema, G.H.; Loerakker, W.M.; Hamers, Maria E.C..

Various old records of Phoma lingam (teleomorph Leptosphaeria maculans) on non-cruciferous plants proved to be based on misidentifications. In the past the fungus has also often been confused with other fungi occurring on crucifers. Forty-five species formerly classified under the generic synonyms Plenodomus, Diploptenodomus, Leptophoma and Deuterophoma were excluded from Phoma sect. Plenodomus, seventeen of them being non-scleroplectenchymatous species of Phoma. Asteromella cocogena, Asteromella pomi and Phoma versabilis are described as new species and twelve new combinations are proposed: Ascochyta aggregata (Höhnel), Cytosporella cenangium (Corda), Fusicoccum hoveniae (Gucevicz), Phacidiella hiemalis (Desm.), Phoma cruenta (Sydow), Phoma filarszkyana...

Contributions towards a monograph of Phoma (Coelomycetes) – X. Section Pilosa (taxa with a Pleospora teleomorph) and nomenclatural notes on some other taxa

Ano: 1996

URL: http://www.repository.naturalis.nl/record/532043

The two anamorphs classified so far in Phoma sect. Pilosa (‘hairy’ pycnidia in vitro) are both metagenetically related to species of the ascomycetous genus Pleospora. In addition to their characteristics in vitro and in vivo short comments on the hosts, literature data, ecology and distribution are given. The notes include additional documentation of the type specimens (dried cultures) of the recently described Phoma schneiderae Boerema et al., Phoma pimpinellae Boerema et al. and Phoma leveillei var. microspora de Gruyter & Boerema. Some excluded species are discussed as new proposed taxa: Asteromella ulmi nom. nov. (teleom. Mycosphaerella ulmi Kleb.), Microsphaeropsis fuckelii (Sacc.) Boerema comb. nov. (teleom. Leptosphaeria coniothyrium (Fuckel)...

Contributions towards a monograph of Phoma (Coelomycetes) — VII. Section Sclerophomella: Taxa with thick-walled pseudoparenchymatous pycnidia

Ano: 2003

URL: http://www.repository.naturalis.nl/record/531958

Boerema, G.H.; Gruyter, J. de.

This paper deals with ten species of Phoma, characterized by thick-walled pseudoparenchymatous pycnidia. They superficially resemble the thick-walled pycnidial phenotype in species of Phoma sect. Plenodomus, but scleroplectenchyma is lacking and teleomorphs belong to Didymella, not Leptosphaeria. Keys and indices of host-fungus and fungus-host relations are provided and short comments on the ecology and distribution of the taxa are given.

New names in Phoma

Boerema, G.H.; Gruyter, J. de; Noordeloos, M.E..

The names of two species of Phoma, discussed in our recent papers (de Gruyter & Noordeloos, 1992 and Noordeloos et al., 1993) appeared to be illegitimate as later homonyms (Art. 64). Therefore the following new names are proposed as avowed substitutes.

Contributions towards a monograph of Phoma (Coelomycetes) VIII. Section Paraphoma: Taxa with setose pycnidia

Ano: 1995

URL: http://www.repository.naturalis.nl/record/531783

Gruyter, J. de; Boerema, G.H..

In this paper eleven species of Phoma with obvious setose pycnidia, grouped in the section Paraphoma, are documented and described. Most of these species were formerly classified in Pyrenochaeta. The following new taxa have been proposed: Phoma briardii nom. nov., Phoma carteri nom. nov., Phoma glycinicola nom. nov., Phoma indica (T.S. Viswan.) comb, nov., Phoma setariae (H.C. Greene) comb. nov. and Phoma leveillei var. microspora var. nov. Indices on host/substratum-fungus and fungus-host relations are included and short comments on the ecology and distribution of the taxa are given.

Boerema, G.H.; Dorenbosch, M.M.J.; Kesteren, H.A. van.

The new combination Cheiromycella chomatospora (Corda) is proposed for the species described by Corda as Coniothecium chomatosporum, a name later often misapplied. The new combination Phoma sorghina (Sacc.) is introduced for the species discussed in a former paper under the misapplied name Phoma glumarum Ell. & Tracy.

Contributions towards a monograph of Phoma (Coelomycetes) VI — 1. Section Phyllostictoides: Characteristics and nomenclature of its type species Phoma exigua

Ano: 1973

URL: http://www.repository.naturalis.nl/record/532251

Aa, H.A. van der; Boerema, G.H.; Gruyter, J. de.

A description is given of the morphological characters of Phoma section Phyllostictoides and its taxonomical position is discussed. A key is provided for the varieties of the type species Phoma exigua Desm., followed by a host-fungus and a fungus-host index. Two new varieties are proposed: Phoma exigua var. forsythiae (Sacc.) comb. nov. and Phoma exigua var. noackiana (Allesch.) comb. nov. The synonymy, selected literature, a representative culture and data on ecology and distribution are given for all varieties.

Phoma herbarum Westend., the type-species of the form-genus Phoma Sacc

Ano: 2001

URL: http://www.repository.naturalis.nl/record/532006

The type of Phoma herbarum is selected and the characteristics of the species are redescribed from recently isolated material. Synonyms of this ubiquitous saprophytic fungus are inter alia: Phoma urticae S. Schulz. & Sacc., Phoma oleracea Sacc., Phoma violacea (Bertel) Eveleigh (described from paint), Phoma hibernica Grimes & al. (described from butter), and Phoma lignicola Rennerfelt (described from wood).

Spore development in the form-genus Phoma

Ano: 1964

URL: http://www.repository.naturalis.nl/record/531840

Diagrams drawn after electron-micrographs of the spore formation in Phoma spp. are shown. The manner in which the spores are formed, called here the ‘monopolar repetitive budding process’, is discussed.

Contributions towards a monograph of Phoma (Coelomycetes) — I. 2. Section Phoma: Additional taxa with very small conidia and taxa with conidia up to 7 µm long

Ano: 1965

URL: http://www.repository.naturalis.nl/record/532462

Gruyter, J. de; Noordeloos, M.E.; Boerema, G.H..

Twenty-seven taxa in section Phoma with conidia not exceeding 7 µm in length are keyed out and described on account of their characteristics in vitro. Four new species are introduced: Phoma aurea de Gruyter, Noordel. & Boerema, Phoma crystallifer de Gruyter, Noordel. & Boerema, Phoma flavescens de Gruyter, Noordel. & Boerema and Phoma subherbarum de Gruyter, Noordel. & Boerema. As new names are proposed Phoma chenopodiicola de Gruyter, Noordel. & Boerema, Phoma pereupyrena de Gruyter, Noordel. & Boerema and Phoma selaginellicola de Gruyter, Noordel. & Boerema. New combinations of species originally classified in Phyllosticta Auct. include: Phoma ajacis (Thümen) v.d. Aa & Boerema, Phoma arachidis-hypogaeae (Vasant Rao) v.d....

Remarks on species of Phoma referred to Peyronellaea—III

Ano: 1993

Boerema, G.H.; Dorenbosch, M.M.J.; Kesteren, H.A. van.

Additional data are given on synonymy and hosts. The ubiquitous species commonly known as Phoma prunicola (Opiz) Wollenw. & Hochapf., a later homonym of Phoma prunicola Schw., is renamed Phoma pomorum Thüm. Phoma indianensis (Deshpande & Mantri) Boerema & al. appears to be conspecific with Phoma glumarum Ell. & Tracy described earlier; its occurrence on rice seed is widespread.

Nomenclatural notes on some species of Phoma sect. Plenodomus

Ano: 1971

URL: http://www.repository.naturalis.nl/record/531988

Boerema, G.H.; Kesteren, H.A. van.

This paper deals with the synonymy of five species of Phoma formerly referred to Plenodomus: Phoma astragalina (Gonz.-Frag.) comb. nov., Phoma petrakii nom. nov., Phoma pezizoides (Ell. & Ev.) comb. nov., Phoma ruttneri (Petr.) comb. nov. and Phoma sclerotioides (Preuss) ex Sacc. (in phytopath. literature well known as Plenodomus meliloti Dearness & Sanford). Further a review is given of the synonymy of previously treated species of Phoma sect. Plenodomus.

Additional notes on Phoma herbarum

Ano: 1981

URL: http://www.repository.naturalis.nl/record/532271

The sporogenesis of Phoma herbarum Westend., and Phoma species in general, is discussed. Additional data are given on the synonymy of P. herbarum and the status of its various infraspecific taxa is revised. Most of the ‘varieties’ and ‘forms’ appear to belong to the ubiquitous species Phoma exigua. Phoma macdonaldii is proposed as a new species and Stagonospora samarorum (Desm.) as a new combination.

Contributions towards a monograph of Phoma (Coelomycetes) — III. 1. Section Plenodomus: Taxa often with a Leptosphaeria teleomorph

Ano: 1970

URL: http://www.repository.naturalis.nl/record/531750

Boerema, G.H.; Gruyter, J. de; Kesteren, H.A. van.

Twenty-six species of Phoma, characterized by the ability to produce scleroplectenchymatous pycnidia (and often also pseudothecia) are documented and described. An addendum deals with five atypical species, but which on account of literature data may be related. The following new taxa are proposed: Phoma acuta subsp. errabunda (Desm.) comb. nov. (teleomorph Leptosphaeria doliolum subsp. errabunda subsp. nov.), Phoma acuta subsp. acuta f. sp. phlogis (Roum.) comb. nov., Phoma congesta spec. nov. and Phoma vasinfecta spec. nov. Detailed keys and indices on host-fungus and fungus-host relations are provided and short comments on the ecology and distribution of the taxa are given.
