Hi,
This white hyphomycete quickly appeared within a week on a specimen of Nemania serpens from the Longshaw Estate, which was kept in an icubator. I was interested to know whether this is a parasite or an anamorph of the Nemania, as the pyrenomycete continued to produce ascopspores in profusion for a few weeks, together with the growth of the hyphomycete. However, the hyphomycete appears to be filling the empty chambers of the Nemania so I assume it's a parasite ie another species of fungus.
The conidiophores are white, bushy and about 1mm high. The hyphae septate, 2-3 um wide, with phialide-like mostly dichotomous branching. Conidia are pinched off the tips of the hyphae and are oval, hyaline, 2-4 x 2-3.
This doesn't seem to be listed as a fungus on "Hypoxylon" in Ellis and Ellis.
Kind regards,
Steve
