Pezizellaceae (?) on Calluna vulgaris
Enrique Rubio, 27-07-2016 21:09

Hi again


These gregarious, small apothecia (150-300 micr. in diam.), translucent, broadly sessile, minutely downy apothecia were growing on a copious brownish subiculum on a branch of Calluna vulgaris at 1700 m of altitude.


The excipulum is made by cylndrical undulate hyaline hairs denesely packed, perhaps gelified, very difficult to dissociate, with smooth tips and slightly thickened walls. Ascospores with some small polar LBs. Asci IKI b, 8-spored, with croziers. Paraphyses filiform, without VBs.


Maybe could be related with the old genus Pezizella? Have you some idea for me?


Thanks again

Re : Pezizellaceae (?) on Calluna vulgaris
Dear Enrique,
yes Pezizella is most likely the genus used for this finding.
There is a Pezizella ericacea D. Read which should be a important mycorhiza partner for Calluna, unfortunately I do not have the article (Trans Br Mycl Soc 63; 381-383 1974) where cultivated apothecia are described.
good luck,
Stip

Hi Stip and Guy


The excipulum of Reid's fungus is very close to the mine, but regrettably I think the somewhat broadly ellipsoid, 5-12 x 3-4 vs the narrowly ellipsoid, subclavate, 9-11 x 2-3 ascospores of my fungus don't fit well.


Anyway many thanks to both

Re : Pezizellaceae (?) on Calluna vulgaris
Pezizella ericae is Rhizoscyphus ericae and surely different.

I remember Pezizella parasitica Velen. which has a similar excipulum. But there the spores have a high oil content and the asci without croziers. Anyhow, the two species could be congeneric.

A further sample, "parasitica-like H+" on Salix, has exactly the excipulum as yours, look sections named Helotiales on Salix wood, HB 9938-6a, KOH etc. But apothecia are much larger (1-2 mm).

All is in my folder Hyaloscypha.

Hi Zotto


Really your HB 9938 is microscopically very similar


Thanks!
