Help with this one much appreciated, on rotting Fa
I have a Hysterium on resin from bark of Picea abies. It deviates from H. pulicare found on a nearby tree. The ascomata are narrower and more upright with a slightly "sharper" apical edge, and a narrower base. Spores measure 20-26 x 6-8 microns, 3-septate without constrictions and end-cells not notably paler (only on a few of the spores). Could it be H. angustatum? (Is H. angustatum synonymous with H. acuminatum?). Or is this within the variability of H. pulicare?
Hi Edvin,
To my mind, it's definitively not H. pulicare.
H. angustatum is considered to be the most widespread species, in a variety of substrates (including Picea). But your collection, which I would link to H. angustatum, is still atypical. Perhaps a serious study would be necessary to better understand what H. angustatum really is.
Getting molecular data could be an excellent idea, as an anticipation.
