Feeding:

Classified as hyphal feeding (Yeates et al., 1993) and probably on more complex fungal structures.

Wood (1973) observed Tylencholaimus montanus feeding and reproducing on fungi in tissue culture.

Okada et al (2005) studied the biology of Tylencholaimus parvus as a representative of K-strategy fungivores. Population growth rates were determined on nine fungal species on agar and on soil-based media. Population growth rates of T. parvus on PDA were substantial on three plant-pathogenic fungi, Botrytis cinerea, Fusarium oxysporum and Phoma herbarum. On the soil-based medium, the fungi, Coprinus cinereus, Flammulina velutipes, F. oxysporum and P. herbarum also supported large population growth rates of T. parvus.

However, T. parvus always had significantly smaller population growth rates than the r-strategist fungivore Aphelenchus avenae, an r-strategic fungivorus nematode, (0-24% of those of A, avanae) on all fungal species tested..

Tylencholaimus parvus was able to avoid predation of the two nematophagous Pleurotus species. It fed on the fungal hyphae and reproduced. In contrast, A. avenae was killed and consumed by Pleurotus
