The nematode-trapping fungus <i>D</i>. <i>flagrans</i> produces adhesive traps, spores, and chlamydospores.

(A) Formation of a three-dimensional trapping network. (B) Trapped nematode C. elegans. Chlamydospores, normal spores and traps are labelled with arrows. (C) Complete degradation of C. elegans and fungal growth inside the nematode. (D) Asexual spore. (E) Chlamydospore. (F) Conversion of single trap-compartments into chlamydospores (star) compared to the conversion of vegetative cells (arrow). (G, H) Glycogen staining with Lugol‘s iodine. (I, J) Visualization of ring-like accumulation of chitin (star) at the contact zone of trap cells with the nematode cuticle. The cell wall of the fungus was stained with calcofluor-white (CFW). Nuclei of C. elegans were labelled with GFP [78]. (K) A X. index adult trapped in multiple D. flagrans networks (stars) after 48 h of co-incubation. The nematode body is completely filled with hyphae, revealed by CFW staining. (L, M) Magnification of the framed area in (I) and turned 90 degrees counter clockwise. The star indicates the trapping network around the head region of the nematode.
