A hypomycete fungus with colorless clavate conidia was isolated from soybean roots. Seven rhizosphere bacteria andAzotobacter from an alternate source induced ascocarps in culture plates. Some bacteria retarded mycelial growth rate and some promoted conidiation. The anamorph and teliomorph resembleDactylella rhopalota Drechsler andOrbilia sp. respectively. 

A review on the research of nematophagous fungal species

This review presents progress made in the field of fungal antagonists of parasitic nematodes, including trapping fungi, endoparasitic fungi, toxin-producing fungi and opportunistic fungi.

Effects of carbon and nitrogen sources on sexual reproduction of five strains from the ascomyceteOrbilia

This study examined the effects of carbon and nitrogen sources as well as the ratio of carbon to nitrogen on apothecia formation of five anamorphic strains from the genus Orbilia and found little effect of variable carbon-nitrogen ratio on aphecia formation.

Taxonomy of Dactylella complex and Vermispora. II. The genus Dactylella

The anamorph genus Dactylella is extremely heterogenous, comprising members of saprotrophic, oospore or nematode-egg parasites. In view of the vast biological differences, a subdivision into more

Orbilia laevimarginata sp. nov. and its asexual morph

By combining morphological and phylogenetic analysis, it is concluded that the three isolates of O. laevimarginata belong to a single undescribed holomorph species.



Ascocarp induction in a natural auxotroph of a predatory fungus

It is discussed that the auxotroph is essential to the initiation of sexual morphogenesis in these anamorphs.

The influence of bacteria on trap induction in predacious hyphomycetes

The induction of traps by the nematode Panagrellus silusiae in four fungal isolates of Dactylaria brochopaga and Arthro-botrys conoides was strongly influenced by several species of bacteria, which

Nemin: a Morphogenic Substance Causing Trap Formation by Predaceous Fungi

The active principle was extracted from worm-free Culture filtrates and named "nemin," and the identity of nemin remains to be established.

A natural auxotroph of a nematode-trapping fungus

The nutritional requirements of a unique predatory fungus isolated from forest soil and has an absolute requirement for histidine and methionine with a partial requirement for several other amino acids are described.

Dactylella oviparasitica, a New Fungal Parasite of Meloidogyne Eggs

Dactylella oviparasitica was isolated from root-knot nematode (Meloidogyne sp.) egg masses and is capable of actively parasitizing eggs of the nematodes.

A new nematode-capturing Dactylella and several related Hyphomycetes.

A twenty-second mucedinaceous fungus of similar predaceous character and having taxonomic kinship in the same intimate series is described herein as a new species.

Unilateral Stimulation of Microsporum Audouini by a New Species of Bacillus

During the comparative study of the genus Microsporiu,m Conant (1) found that M. Auldouini, in sharp distinction from Microsporum lanosum, does not vegetate at all on rice medium. He thus established

Influence de l'association nématodes-bactéries sur la formation des pièges chez l'hyphomycète prédateur Arthrobotrys oviformis

On compare la reaction d'un champignon nematophage en presence de nematodes phytoparasites non associes a des bacteries et en presence de nematodes libres porteurs de bacteries. Etude des mecanismes

A Dactylella with Conidia Resembling those of Dactylella Stenobrocha in Size and Shape

Several maizemeal-agar plate cultures, which, after being overgrown with mycelium of Pythium mamillatum Meurs, had been further planted with small quantities of leaf mold collected in deciduous woods

Some Hyphomycetes that Prey on Free-Living Terricolous Nematodes

In several preliminary summaries, the morphological features of 16 fungi observed to subsist by the capture of free-living nematodes infesting old agar plate cultures started from various decaying plant materials were set forth.
