Bisporella sulfurina?
William Slosse, 11-03-2017 21:28
William SlosseI always find it hard to distinguish citrina from sulfurina.
Am I right that this one is sulfurina?

° Matured spores with mostly 4 oildrops and one septated / 10.54x2.98mu
° asci with no croziers
° growing in clusters

Thx in advance,

William

Re : Bisporella sulfurina?
It is not easy to confuse these two species! What you show is clearly B. sulfurina (or now Calycina claroflava). When you apply Lugol you will not see an amyloid apical ring whereas B. citrina (Calycina citrina) reacts blue or dirty red at higher concentration.
