Bonjour tousa collection of dead leaves of Phormium tenax (non-native, of course), following a snow thaw has produced a number of fungi, including Stictis stellata and Gyrothrix podosperma.
A Dictyosporium has also appeared: I am finding it difficult to identify, using the paper by Goh et al. in Fungal Diversity 2, pp.65-100. The characters of it being non-complanate, and non-sporodochial, combined with conidial size and number of arms (mostly 5) mean that it does not fit well with anything in that paper. Any thoughts would be very welcome. (The PDF can be zoomed to 300% without pixellation).

The paper in Sydowiav55? yes I have checked it, also:
Photita et al. Mycotaxon LXXXXII (2002)
Tzean & Chen Mycological Research v92 (1989)
Cai et al. Cryptogamie, Mycologie 24 (2003) - includes a key
Tsui et al. Fungal Diversity v21 (2006)
Cai & Hyde Mycoscience v48 (2007)
Wongsawas et al. Cryptogamie, Mycologie 30 (2009)
for anyone interested the Goh et al. paper is available online at: http://www.fungaldiversity.org/fdp/sfdp/FD_2_65-100.pdf
Although the images in that paper, and in Ellis's Dematiaceous Hyphomycetes are not entirely satisfactory, this collection will have to go down as Dictyosporium cf. oblongum
