Crocicreas tomentosum?
Marcus Yeo, 24-07-2014 20:54
This Crocicreaswas growing on dead grass stems.

Apothecia are cream, <1.2 mm diam, long-stalked.


The excipulum is a textura oblita. In the upper part of the apothecium and protruding from the margin there are brown hyphal "hairs" <60-70 µm long, tending to clump together in groups.


Asci are 40-50 x 3-4 µm, 8-spored, blue tip in IKI.


Paraphyses are cylindrical, with abundant refractive VBs, about as long as or slightly exceeding asci, 2-3 µm wide.


Spores are 7-11 x 2 µm, 0-septate, with a few small OBs.


It seems closest to Crocicreas tomentosum but doesn't completely match the descriptions in Carpenter's monograph and elsewhere. For example, the hyphal "hairs" appear to be smooth (described as rough in Carpenter) and are aggregated in distinct clumps on the apothecial margin, and are absent from the lower part of the apothecium.


Any ideas welcome. Many thanks.


Marcus

Re : Crocicreas tomentosum?
It is a mess with these Cyathiculas. C. cyathoidea is a collective species but it is hardly possible without genetics to get an idea which "subspecies" it belongs. I would not exclude C. cyathoidea s.l. here.

Re : Crocicreas tomentosum?

Thanks, Zotto. I will err on the side of caution and stick with Crocicreas/Cyathicula sp for this specimen!
