Observation 198453: Helotiales Nannf. ex Korf & Lizon
When: 2015-02-10
No herbarium specimen

Notes: This was growing on a well rotted leaf of umbellularia, california bay.

A number of the Observations on MO mention this growing on Eucalyptius seeds. This leaf could have been a decayed eucalypt leaf. It was among eucalypt wood chips where some huge eucalyptus globulus had been felled.

(I found others) spores are immature. Björn Wergen thinks that it’s not even a Rutstroemia. It’s a riddle this thing, I look forward to know what it is.

Neat!

Look into Rutstroemia – I dont’ remember what the microscopic features are to look for.
