Observation 34296: Tubulicrinis chaetophorus (Höhn.) Donk
When: 2010-01-31
Herbarium specimen reported

Notes: This resupinate came from the inside bark of a dead, burned bishop pine near the Bayview trailhead. I thought I had a spore print for it, but it turned out to be a mixed collection with a second resupinate. After some searching I found a short spore, ellipsoid spore (5.4 X 3.1) that was associated with the material and is the right size (almost) for the species. The pointy "lycocysidia’ are the main feature that suggests the species, but as with all these crusts I’m still in the learning phase and not very sure of my species calls. The presence of Lyocystidia, however, makes me pretty sure of the genus.

Nothing special here – the other two sterigmata are not visible in this plane, but were present, as was a basal clamp.

This is a closeup of the fruitingbody after it was dried showing a very loose array of hyphae. The fuzzy look to them (aside from the poor focus) is caused by the many projecting cystidia

they dissolve completely in KOH! makes you wonder how many crusts and poroids have them but are described without them due to descriptions from dried material revived with KOH.
