cortex lies a peculiar white-yellowish tissue, composed of transversal fibres 

 and inwardly fixed to a tough, dark axile string which as a rule will keep 

 unbroken when the clavula is broken. The asci are very long-stalked, the 

 length of the pedicel in a single case reaching 90^; most of the stalks 

 however seem much shorter because they are fragile and will easily 

 break. — On brittled wood.
