Forming thin, adherent, irregular, ill-defined or fairly well-defined patches 
24 to 6 x T( to lin. (6.2 to 15 x 0.6 to 1.2 cm.) in extent. Deep Chrome (m.) or 
near Y^ellow Ochre (xv.) and Eaw Sienna (ill.) when fresh, when dry near 
Y'ellow Ochre (xv.) but dingier and darker in places, sterile edge sometimes 
grevish with a white fluffy border. Subiculum very thin, somewhat floccose, paler
