Observation 160589: Nectria cinnabarina group

The fruitbodies are obviously dessicated, perhaps also damaged by frost so it is difficult to know what they originally looked like.

from https://www.ncbi.nlm.nih.gov/...:

Nectria cinnabarina s.s.

Distribution: Europe (Austria, Denmark, France, Germany, Ireland,
Netherlands, Poland, Sweden, Ukraine, UK) and North America
(Canada, USA).

Habitat: On dead woody substrata including Acer campestre, A.
, A. pseudoplatanus, A. saccharum, Acer sp., Aesculus
, Celastris scandens, Fagus sp., Gleditsia sp., Populus tremula,
Sorbus aria, Spiraea trilobata, Tilia sp., and Ulmus × hollandica.

a Florida record from the USDA Fungus Host Database indicates N. cinnabarina is associated with black cherry in the form of dieback", meaning that perithecia were probably not observed or studied, but that some plant damage attributed to that species was evident. this could be some warping/curling/mutation of wood/leaves/stems. chances are the name was misapplied, as has often and long been the case with N. cinnabarina.

Suspect #1=Yellow birch; Suspect #2=black cherry

Thanks for asking – does substrate inform identification?
