CULTURES AND ANAMORPH

Hypocreodendron anamorph lining interior and sometimes the exterior of terminal discs, orange to bright orange, with surface at first smooth, but becoming pitted as areas senesce.

Conidiophores stout, arising from underlying tissue of textura intricata, bearing conidiogenous cells 9-20 Ám long x 1.5-2 Ám diam in digitate configuration or false whorls. Conidia produced holoblastically; conidiogenous cells proliferating percurrently.

Conidia hyaline, more or less clavate with end that seceded from conidiogenous cell often somewhat swollen or flared, 8-15 x 1.5-2 Ám.

Discoxylaria myrmecophila in culture

Colonies on PDYA incubated at ca. 20C and 12h fluorescent light covering 9 cm petri plate in 10 da, thin, whitish, producing more or less typical stromata from center of plate outward. Hypocreodendron state on discs identical to that found in nature and described earlier. Perithecial fundaments produced in stipes, but mature perithecia not observed. Conidia swelling at end opposite secession scar, but not producing germ tube.

Culture deposited in American Type Culture Collection.
