NOTES

For a detailed description, see Egan (1978).

This species is characterized by the absence of salazinic acid and by a white to pale brown lower surface with sparse rhizines. The marginal cilia are sparse and short but sometimes numerous and long, up to 2 mm long ( Culberson & Culberson 1981). This species resembles H. cirrhata in morphology but differs in the absence of salazinic acid, the presence of protocetraric acid (medulla K-, KC + pale red), and a white lower surface near the tips.
