Sistotrema coronillaObserver
maricel-patinoDescription
Underside of deciduous bark. Park. What a surprise! The white cordons are supporting spheres that start white and as they mature, turn light brown-peach. Each sphere is made of inflated cells; one measured 74 um in diameter. There are several types of clamps.
Karen Nakasone told me that these are called bulbils and Sistotrema and Leucogyrophana s.l. produce them.

This was an old specimen, so I couldn't find living asci with alive spores.

Fir Disco (Pithya vulgaris)Observer
ikhomDescription
On Abies balsamea branches with needles still attached. The trees were uprooted 2 years ago during the spring storm.
The cups were still immature, so I couldn't find any asci.
Paraphyses filiform, septate, branching, with VBs in the top segment, 3.5-5.2um in width.
