Anamorph on Phragmites
Stefan Jakobsson, 17-06-2021 01:15
Normally I try to avoid anamorphs but this one is so special that I could not leave it alone. It was growing scattered on a culm of Phragmites australis on moist ground, southern Finland.

The sporodochia are rounded to oblong, to 0,4 × 0,7 mm, pulvinate, setose. In wet condition the slimy mass of conidia is light grey, drying to darker gray and finally dark brown. It has two kinds of setae, the acuminate type is up to at least 300 µm long, very dark, opaque, with at least some septa below. The other type with a rounded apex is up to 170 µm, smokey brown with a lighter apex, no septa. Both types have a bi- or multifurcate base. The excipulum has light brown cylindrical hairs. The conidia are 10.3 - 12.5 × 2.3 - 2.6 µm (excl. appendages), guttulate, with a 5-10 µm long filiform appendage at each end. Conidiogenous cells in the last photo.


My best guess is something in Koorchaloma but i can't find a matching species. Are there better suggestions?

Re : Anamorph on Phragmites
Hi Stefan

I do not know this type of mushroom, but Dinemasporium strigosum was noting on Phragmites?

Maybe it is worth comparing?

Re : Anamorph on Phragmites
Thank you, Dinemasporium seems to be the way to go. It has the same type of conidia and the same types of setae. I will check that later.

On this topic, an article is available on the internet:

How important are conidial appendages?
