Remarks

This is a species difficult to recognize without knowing the identity of the hosts. It lacks striking characteristics and can be confused with other species showing unbranched outer appendage like L. rigida Thaxt. and L. polyphaga Thaxt. The inner appendage changes with age, and a large series of thalli in good condition is needed to obtain some undamaged thalli showing this portion of the thallus as originally described. According to De Kesel et al. (2020) proliferation of inner appendage occurs more frequently in thalli from P. diligens than in those from P. strenuus .
