The arid Middle East extends over 9 million km² in the Eastern part of the Mediterranean Sea. Interest in the fungi of this region after the Second World War led to the discovery of species then regarded as being new to Science. A scan of the Index of Fungi issued in the period running from 1940-2000 revealed that 240 novel taxa had then been propo...

A revisit of the publication entitled ‘Fungi centro-africani’ by P. Hennings (1898) is presented and the 32 taxa reported are taxonomically re-evaluated. Most specimens were collected by G. Schweinfurth during his third trip (1868-1871) in the wide and politically unsettled region then known as Central Africa. Two additional species were collect...

The present synopsis reports on taxonomic decisions and name changes introduced in the last decades for a number of thermophilic fungi. Taxa dealt with are those most commonly cited in the literature of fundamental and applied work or concern species having complex taxonomic histories. The definition of a thermophile follows the classificatory sche...

In applied research work dealing with heat-tolerant fungi, currently classified into two groups: namely thermotolerants and thermophiles, information on levels of thermotolerance is generally scant. Cited binomials are often referred to as representatives of thermophilic taxa. The present contribution attempts to specify proper heat-tolerance level...

Leiothecium ellipsoideum Samson and Mouchacca, gen. et sp. nov., is characterized by dark, glabrous ascomata with thin pseudoparenchymatous walls and by ellipsoidal, reticulate, hyaline, one-celled ascospores. Rhexothecium globosum Samson and Mouchacca, gen. et sp. nov., has pseudoparenchymatous initials and is related to the genus Eremomyces Mallo...

The third part of this series surveys 61 coelomycetes described before 1940 with holotypes originating from the Middle East. The taxa concerned were examined in relation to their authors, dates of publication, collectors and original locality. The taxonomie positions were updated following the current taxonomy of the fungi concerned. The two major...

The present note is the first of a series surveying novel fungal taxa named before 1940 and with original localities in the arid Middle East region. The survey will consider members of the well represented taxonomic groups, i.e. non lichenized Ascomycetes, anamorphic fungi, Homo- and Hetero- Basidiomycetes. It is in line with published contribution...

Heat tolerant fungi are organisms that may perform bioconversion processes and produce industrially important metabolites. They may either be obligate thermophiles or simple thermotolerants. The present document is the continuation of a critical note on thermotolerant fungi erroneously reported in the literature as possessing thermophilic attribute...

Despite recent progress achieved in the stabilisation of the systematic of thermophilic fungi, a few names remained unassesed. Among the three zygomycetous taxa considered Mucor miehei var. minor and M. thermohyalospora are regarded as possible synonyms of Rhizomucor miehei; Mucor thermoaerospora and its variant name M. thermoaerosporus represent a...

Information on presumed marked heat tolerance levels of about 20 fungal taxa, referred to as pseudothermophilic fungi, is critically reviewed. This assessment also includes individual nomenclatural status and correct taxonomic position. For several, the assumption conveyed by their specific epithet thermophila (also thermophilus, thermoideum or the...

A critical check-list of novel fungal taxa having original localities in the arid Middle East region and introduced between 1940 and 2000 is presented. The list considers 246 taxonomic units at the species and subspecies levels. The taxa are grouped according to major Classes of Fungi. For each taxon the reference, country of origin and the nature...

Succeeding two compilations respectively of novel soil-borne fungal taxa and of novel taxa from habitats other than soil, 54 additional novel taxa similarly originating from the arid Middle East and introduced since World War II are here documented. 41 genera are represented. They concern 27 Ascomycetes (including ten lichenized and one lichenicolo...

Basic descriptive taxonomic references are documented for fungi new to science introduced over the years 1940-2000 from various localities of the Middle East. The 186 relevant titles are listed in alphabetic order of the authors' names. These titles convey the protologues of 254 taxonomic units at the species and infraspecific levels. Each title is...

The present selection of bibliography on the biodiversity and plant pathology of African fungi introduces around five hundred titles appearing up to 1994. Titles annotated are those regarded as being of marked importance in respective fields. Each comprises the relevant basic bibliographic details and, for most, a concise annotation on the scope of...

Type collections of Cercospora byrsonimatis and Ramularia ligustrina have been re-examined. Cercospora byrsonimatis is transferred to Pseudocercospora while a second hyphomycete, found on the type material, is described as Ramalia byrsonimatis sp. nov. Ramularia ligustrina is redescribed and its status as a true member of Ramularia is confirmed.

This second contribution on A. Maublanc focuses on the status of the binomials he introduced. For each binomial, basic bibliographic information with characteristics of type material are given. An extensive search was undertaken to find authentic material in the few collections comprising specimens he examined. These collections, formerly dispersed...

This note introduces the scientific contribution of Andre MAUBLANC (1880 - 1958) through a short biography and an annotated list of his writings. Over one hundred titles pertaining to the fields of phytopathology and mycology could be retreived. They focus on diseases of cultivated plants of temperate and tropical regions, on the taxonomy of their...

The type specimen of the smut fungus Ustilago andropogonis-funitimi, recently re-discovered, has been studied and described. The binomial is recombined in Sporisorium. Previously proposed synonymy is discussed and the confusion surrounding the original description is clarified.

An annotated list of publications relating to fungi of New Caledonia is presented. Over two hundreds titles were retrieved, starting from the year 1845. Interestingly more publications were issued from the start of the new European settlement in 1853 up to the first World War, than for the period between the two World Wars. For the latter only four...

The present note introduces the scientific achievements of André Maublanc (1880–1958) through a comprehensive biography, a yet unpublished list of his publications and of taxa he introduced grouped following localities of origin. Over one hundred titles pertaining to the fields of phytopathology and mycology were located. These notes of fundamental...

In the present paper, cercosporoid hyphomycetes known from New Caledonia, Vanuatu (New Hebrides), Wallis and Futuna, and French Polynesia are summarised and discussed, along with a few collections from Fiji and Samoa. New species Cercospora phaseolicola, Cladosporium nigrel‐loides, Phaeoramularia malpighiae, Pseudo‐cercospora alocasiae, P. aracearu...

Succeeding a compilation of novel soil-borne fungi, 143 new taxa described since World War II from habitats other than soil from the Middle East area are critically evaluated. The area covered includes Libya and The Sudan. Half of these taxa have collecting sites in former Palestine territory including present Israel; Egypt and Irak together share...

Fungi have the ability to grow over a wide range of temperatures. The response of fungi to this major environmental variable ranges along the downward cline from obligate thermophily through mesophily to psychrophily. In terms of species number, present data confirms that the majority of taxa known to grow in culture are mesophiles developing betwe...

An annotated check-list of plant pathogenic basidiomycetes collected mainly in New Caledonia is presented, supplemented by a few similar records from French Polynesia. The list is basically prepared from specimens present in the neocaledonian herbarium. Specimen annotations were checked with available literature. Few specimens proved not to be repo...

An annotated check-list of non-phytopathogenic basidiomycetes from the island of New Caledonia and its dependancies (Loyalty Islands and Isle of Pines) is presented. Scanning publcations stressed the necessity to also include the few early records of this group of fungi reported from French Polynesia and Samoa. The content of the list was drawn fro...

Interest in fungi of the South Pacific region dates back almost two centuries. This paper deals with ascomycetous taxa having protologues based on material collected mostly in New Caledonia and French Polynesia. Over one hundred taxa have been described from these islands. Available information suggests that the majority have not been the subject o...

A short account on the life history of the French phytopathologist Francis BUGNICOURT (1907-1991) is presented. Follows an annotated list of the author's publications and a list of taxe he proposed as being new for Science. The taxonomic status of these novel fungi has been updated. All taxa described have original localities in either Vietnam or N...

A critical reappraisal of nomenclatural status and in some cases also of taxonomic ones was undertaken for known thermophilic fungi. Distinction between thermophilic and thermotolerants follows definitions elaborated by Cooney & Emerson. Altogether less than forty species and varieties are able to achieve best development at high temperatures. Furt...

An overview of key issues that emerged at the First International Workshop on Ascomycete Systematics is presented. The value of various characters used in, and approaches to, ascomycetes in various groups are highlighted. The main challenges identified for the future are the holomorph concept, the use of supraordinal ranks, alternative terminologie...

In this session we have a formidable array of taxa to consider, many of which few of us will be personally familiar with. We propose to discuss these in turn.

A computerized listing fungus-host-plant is proposed. -from English summary

Continuous screening over 30 d of large foliar surfaces incubated in damp-chambers proved to be essential for delimitation of the various ecological groups of fungi. -from English summary
