Synnematal fungi from Fagus wood
Alex Akulov, 22-08-2010 14:35
Alex AkulovSynnemata scattered, gregarious to caespitose, gelatinose, spherical, with wide prostrate base, but without stipe, typically whitish when fresh and yellowish-brown after drying; quickly soaked and lighter in the water, but virtually no change color in KOH. Conidiophores branching 2-3-level verticillate or irregularly biverticillate, resemble those of the Stilbella flavipes. Phialides in terminal or intercalary whorls of 3-6, or lateral and terminal, cylindrical to subulate, straight or sinuous, that placed an acute angle to the conidiophore axis, sometimes with irregular constrictions, 22-38 µm long, 1.4-1.9 µm wide, Conidia ellipsoidal to ovoid, 3.1-4.1 (-5.0) x (1.7-) 2.0-2.3 µm, sometimes grouped in the tops of phialides in spherical masses.
This species is frequently detected by me on the heavily damaged wood of Fagus sylvatica in the Carpathian Mountains.
For several important features my specimen reminds Stilbella flavipes and Dendrostilbella prasinula, but me confused by complete absence of sinnematal stipes, as well as the absence of the characteristic greenish hue. Recommend that this could be and what it is worth paying attention to?

Please advise me that this could be.
Probably this species is also found on the beech trees in France.

Synnematal fungi from Fagus wood - Leucogloea compressa R. Krischner
Dear colleagues
With the help of Keith Seifert from Canada it was found that my sample probably is Leucogloea compressa R. Krischner. See Agerer et al, Frontiers in Basidiomycote Mycology, pp. 165-178, 2004. This anamorphic Basidiomycota representative, which still has not been noted in Europe till now.

Congratulations!

You have done much work with this.
