Summary

The elicitation of perfect organs of fructification in the formgenusMicrosporon (pro parte) by means of an incidentally found bacterial symbiont, theB. weidmaniensis Benedek, 1938 is described.

Furthermore, it is reported on two strains ofMicrosporon which spontaneously yielded identical perfect organs of fructification in the primary culture without any stimulation.

A new genus is established:Veronaia Benedek (Ascomycetes, Perisporiaceae, Aspergillales) which encompasses at present, 1) the type species:Veronaia Castellanii,Benedek, 1960; 2)Veronaia (Microsporon)Audouinii Gruby and 3)Veronaia (Microsporon)felinea Fox &Blax.

The genusVeronaia is cleistocarp and homothallic.

The Latin and English diagnoses of the type species (genus) are given.

The historical importance of this discovery and its impact on future search for the perfect organs of fructification in dermatophytes is discussed.

Zusammenfassung

Die Auslösung einer typischen Schlauchfruktifikation in der Form-GattungMicrosporon (pro parte) mittels eines zufällig gefundenen bakteriellen SymbiontenB. weidmaniensis Benedek, 1938 wird beschrieben.

Ferner wird über zwei Stämme vonMicrosporon berichtet, die in der Primärkultur gleiche Schlauchfruktifikation spontan, ohne irgendeinen Reiz, geliefert haben.

Eine neue Gattung im natürlichen System wird aufgestellt:Veronaia Benedek (Ascomycetes, Perisporiaceae, Aspergillales). Sie umfasst zur Zeit 1) die Typen-species:Veronaia Castellanii Benedek, 1960; 2)Veronaia (Microsporon)Audouinii Gruby; 3)Veronaia (Microsporon)felinea Fox &Blax.

Die GattungVeronaia ist cleistocarp und homothallisch.

Die lateinische und englische Diagnose der Typen-species (Gattung) ist gegeben.

Die geschichtliche Bedeutung dieser Entdeckung und ihr Einfluss auf zukünftige Untersuchungen betreffs der Schlauchfruktifikation in den Dermatophyten wird erörtert.

Résumé

L'auteur reporte sur la découverte de la vraie forme de réproduction dans le forme-genreMicrosporon (pro parte) deSabouraud par le moyen d'un symbionte bactérien, leB. weidmaniensis Benedek, 1938, découvert incidemment.

En outre, il reporte sur deux souches deMicrosporon lesquelles ont produit la même forme parfaite de réproduction, spontanément dans la culture primaire sans aucune stimulation.

Un genre nouveau est établi:Veronaia Benedek, gen. nov. (Ascomycetes, Perisporiaceae, Aspergillales) en renfermant à présent (1) l'espèce-type:Veronaia Castellanii,Benedek, 1960; (2)Veronaia (Microsporon)Audouinii Gruby et (3)Veronaia (Microsporon)felinea Fox etBlax.

Le genreVeronaia est cleistocarpe et homothallique.

Le diagnostic latin et anglais est assigné à l'espèce-type (genre).

L'importance historique de cette découverte et son influence sur les recherches futures ont été discutées.
