TLDR
The nematophagous fungi (Arthrobotrys oligospora and Monacrosporium cionopagum) were observed under semi-natural conditions by fluorescence microscopy after fluochroming, using fluorescein-diacetate to demonstrate the formation of 3-dimensional sticky networks and the capture of nematodes inside the soil.Abstract:

Methodology for Studying Nematophagous Fungi
TL;DR: Methods for obtaining mixed cultures of the fungi from nature, for isolating taxa into pure culture, for observing living material and for making permanent microscope preparations are detailed in this chapter.

Vital staining of fungi in pure cultures and in soil with fluorescein diacetate
TL;DR: In experiments with pure cultures, good correlation was obtained between relative staining efficiency, growth rate, and respiration, and FDA appears to be a true vital stain, in that it stains only metabolically active mycelia.

Biological Control of Nematode Pests by Natural Enemies
TL;DR: This review of the status of natural enemies for control of nematode pests attempts to analyze recent studies, compile re ports of new organisms and stimulate and guide future research in this important field.

Nematode-Induced Morphogenesis in the Predacious Fungus Arthrobotrys Oligospora
TL;DR: Living nematodes induced trap formation in Arthrobotrys oligospora more rapidly than did additions of morphogenetic peptides, and ammonia was shown by gas chromatography to be excreted in nematode suspensions in amounts that could affect trap formation.

Ecological characteristics of nematode ‐trapping Hyphomycetes
TL;DR: It appears that the development of predaceous efficiency has been accompanied by a tendency to lose those characters associated with an efficient saprophytic existence in the soil; namely rapid growth rate and good competitive sa Prophytic ability.

The predaceous activity of nematode‐trapping fungi added to soil
TL;DR: Evidence suggests that fungi forming the constricting ring type of trap are more efficient in reducing soil nematode populations than fungi forming adhesive reticulate traps.
