not getting hung up on it. Someone may have clicked the wrong rating.
Or, someone might have intentionally clicked the low rating, but as long
as YOU know that it is useful (which it absolutely is) who cares?
You and I and most everyone serious about ID on this site knows you do a
marvelous job of illustrating what you seen in that scope.

Okay but not so useful ?

Oluna complains that her comprehensive drawing of Dacrymyces variisporus was found “Okay but not so useful”. What more should she do? None of the illustrations we saw would have so many characters illustrated. For instance, none of the illustrations we have seen would show the apical thickening of cortical hairs, typical for this species. On the other hand, we agree that this drawing is not very useful, if you don’t use a microscope for your identifications. – Adolf

It is not Heterotextus alpinus!

Heterotextus alpinus: Spores are 3-septate at maturity, 14-16.5(18) x 4.5-5.5, cortex covered by palisade of vesicular, broadly obpyriform cells.

Dacrymyces variisporus: Spores are 3- to7-septate at maturity, (12)16-26(30.5) x 6-9.5 µm, cortex covered with thin- or thick-walled simple or branched hairs, cylindrical, subclavate to clavate [see my drawing!]. – Oluna
