Arnold BüschlenHallo, ich suche zu Cosmospora aurantiicola Lite
On a mat of dried algae/lichens, loosely attached to a herbeceous stem, I found several very small, dirty gray fruiting bodies (diameter 155 to 220 µm), sitting on the substrate.
Asci: club-shaped, thick-walled, 27 x 6.5 µm; reddish-brown in Meltzer and Baral's solution, blue-black in Lugol's solution;
Spore: needle-shaped, stretched, (21.4) 23.6 - 27.2 (27.5) × (1.4) 1.7 - 2.1 µm, no septa, only in IKI 2 septa;
Paraphyses and base asci difficult to observe;
Conidia: filiform, curved, without septa, Me = 31.5 × 1.4 µm (measured with curvature)
Textura: globulosa incrassato-imbuta
Using the key in the publication listed below, I arrive at Bacidina chloroticula.
However, my knowledge of algae/lichens is insufficient to be certain of the identification. Can anyone help me? Many thanks in advance.
