Recognizable by its peculiar pallid, sessile sporangia, as by the internal structure. Perhaps related to Hemiarcyria bucknalli Mass. Our specimens are from Mr. Morgan, of Ohio, with the statement that they were collected in the San Bernardino Mountains, California, by Mr. S. B. Parrish; collected later from Monterey south.
Common throughout south-western states to lower California.
