CULTURES AND ANAMORPH
Colonies on OA not reaching the edge of Petri dish, whitish first, becoming amber (47) towards the edge, hazel (88) or isabelline (65) towards the center, velvety, azonate, with diffuse margins, with citrine (13) pigments diffusing beyond colonies; reverse amber (47), citrine (13), or dark green (21).
Sporulating regions scattered over entire surface of colony, honey (64).
Conidiogenous structure Virgariella-like, hyaline, smooth to finely roughened.
Conidiogenous cells hyaline, smooth, 8-15 x 3-4.5 mm.
Conidia hyaline, smooth, ellipsoid, 5-7.5 x 3-4 mm.
The colonies described above are from cultures of typical H. crocopeplum that is mainly distributed in eastern North America and has spherical to obovoid perithecia. Colonies from specimens with long tubular perithecia grow faster than those from typical specimens, covering a Petri dish in 3-4 wk. However, among these faster-growing colonies, the colony colors and the quantity of sporulation are quite diverse: dark green, sparsely sporulating in those isolated from Mexican and Venezuelan collections, but ochraceous, heavily sporulating in those from Taiwanese collections.
