 Like the head , the stipe is covered in a gelatinous outer layer . The stipe itself consists of a number of anastomosing gelatinous strands , giving the structure a reticulate or spongy appearance . These strands vary in color from red to yellow @-@ brown , and fade with age . The stipe is 1 to 2 cm ( 0 @.@ 4 to 0 @.@ 8 in ) thick and 1 @.@ 5 to 4 cm ( 0 @.@ 6 to 2 in ) long , although some or all of this length may remain buried .
