A Helvella with very small dimensions and in an unusual biotope
François Bartholomeeusen, 03-12-2017 11:53

In the middle of an alder swamp forest, in Belgium, is a dike that the last six months has been inundated by the high water level.
Ascomata was found in November, at the base of a mossy, dead poplar (populus) seemingly growing on the bark.


Apothecium: 14 x 15 mm, saddle-shaped, selliform, grey-green, the brim is not attached to the stipe except one attachment of 0.5 mm wide;
Stalk: dirty yellow, 27 mm long, at the top 6 mm and 4 mm wide at the base, the whole length ribbed, the ribs run 2 mm further on the apothecium;
Spores: elliptical, 15,23-19,43 x 10,36-12,97 µm, Q = 1.53, 1 large drop and several small ones,
Asci: 194,53-261,53 x 16.77-22,17 µm; cylindrical, IKI-;
Paraphyse: septated, filiform, branched and 5 µm wide with up to 8 µm swollen top
Ectal exipulum: textura globulosa-subglobulosa length > 50 µm
Medular exipulum: textura intricate

Could this be Hevella lacunose var. sulcata or is it a H. lacunose that suffered from the wet weather and environmental conditions? Thanks for your help!

Greetings,
François Bartholomeeusen

Re : A Helvella with very small dimensions and in an unusual biotope
Maybe Helvella phlebophora ?

Re : A Helvella with very small dimensions and in an unusual biotope
Hi Nicolas,

Thanks for your good suggestion. I have read the description of H. phlebophora in Ascomycete.org and in Coolia 27 (1) but I still have my doubts. The ribs of the stalk continue on the bottom of the cap but they become very soon furrowed. My spore sizes are also slightly larger.

Greetings,

François
