Ophiocordycepskimflemingiae inserts hyphal
projections into host muscle. In some instances, physical invasion of muscle cells by fungal hyphae is evident (A; boxed regions are shown at higher magnification in B and C; SEM images). Interconnected networks of fungal cells (A, arrows) are able to access host muscle via direct insertion of one fungal cell from the network (B,C). Scale bars: A, 2 µm; B, 1 µm; C, 200 nm. Controls, n=3; infected, n=6.
