Unsichere Bestimmung (Verkrüppelte Wuchsform?): die Kombination der verschiedenen Merkmale passen nicht 100%: Marasmoider Habitus? Ca. 1 mm grosse Fruchtkörper mit fädiger Basis, bzw. ohne Füsschen lateral am Substrat angewachsen. Sporen elliptisch schmal.
"
"
Auffällig sind die vielen Rhizoiden um die Fruchtkörper (siehe Foto 1).
"
Die auffällige Form der Cheilozystiden kann ich im Moment keiner Art zuordnen.
"
"
Marasmiellus candidus hat ähnliche Zystiden, jedoch grössere Sporen, würde jedoch am ehesten passen.
"

Substrat
Morsches Holz, wahrscheinlich Picea
"
Fruchtkörperfarbe / Farbspektrum
Weiss
"
Hutoberfläche
Faserig-flaumig
"
Lamellenmerkmale
Schneiden, eher glatt, aufgrund der Winzigkeit wirken die Lamellen unter der Stereolupe dick.
"
Sporenlänge
Ca. 9-10 µm
"
Sporenform
+/- elliptisch, apfelkernförmig
"
Sporenmembran, Oberfläche, Skulptur
Glatt (mit Öltropfen)
"
Hyphen / Hyphensystem
Septen ohne Schnallen
"
Cheilozystiden
Flaschenförmig, mit langem Hals und teilweise leicht kopfig

Suchbegriffe / Tags: Pleurotellus is now a dead genus, a synonym of Crepidotus, since its type species P. graminicola, despite its smooth ± white spores, is established beyond doubt as a Crepidotus, widely known by the earlier name C. herbarum, now known by the still earlier and thus correct name C. epibryus. All the remaining Pleurotellus species that were interpretable at all and didn’t belong in Crepidotus now have new homes elsewhere. Two of these, listed in NCL (= Dennis, Orton & Hora, 1960: New Check List) as P. patelloides and P. candidissimus have become Chaetocalathus craterellus and Cheimonophyllum candidissimum. These two have both long intrigued me as I have never found either, despite statements in BFF6 (= British Fungus Flora Vol. 6, Watling & Gregory, 1989) that they are respectively “widespread in the southwest” and “rare but widespread throughout the British Isles”. I take this opportunity to add some notes on these two species and their known British distribution. But first I give a brief overview of the fate of the remaining species assigned to Pleurotellus in NCL and/or BFF6.
