Hi
yes it's a hyphomycete, but it helps underline the artificiality of that (still very useful in a general sense) term. The vast majority of hyphomycetes represent the imperfect stage of ascomycete fungi; this is the anamorphic state of a
basidiomycete, a species of
Botryobasidium -
Botryobasidium aureum. This is one of the
Botryobasidium spp. without clamps, so not immediately recognisable as a basidio. I was once assured by Alick Henrici that this species and
B. conspersum can only reliably be distinguished by their imperfect states. Here is the relevant page from
Corticiaceae of Northern Europe Vol. 2; as
Oidium (
Haplotrichum in later works)
aureum:
- Haplotrichum aureum state of Botryobasidium aureum
if you haven't already you can download all the volumes of this work (and/or a unified one) for free here:
http://www.mediafire.com/monographs it's worth exploring that website, there's masses of other extremely useful free downloads on that and associated pages.
hope that helps
