Quest 1948 Journal 37 April 28, 30 mls S E Mesquital, 600ft. Baja California. of Cirios, those present being short and stubby. The Ocotillo here is squat and highly branched, possibly a different species, and covered with what looks like Spanish Moss and is called Orchilla by Tevis. The Orchilla parasitizes everything, including the spines of the barrel cactus and the axils of the Elephanthurius. Yucca is common here, and the vegetation much more dense than but few of the regions around Punta Prieta. Found a mushroom yesterday afternoon (Coprinus comatus) that measured 13 inches from top of pileus to base of stem. The cap was as yet sealed and it was in a highly desiccated condition. Weight of specimen was 112.7 grams. Numerous lichens occur in this vicinity on rocks. The washes of the hill S.W. of Mesquital appear green because of a lichen, and isolated rocks were noticed that had a brilliant red lichen on their tops. Surrounding us are hills topped with lava cap-rock, presumably the remains of the lava plateau south-east of here. Another interesting plant parasite that occurs in this region or mainly Ocotillo looks like a spherical bird's nest and is about 8 inches in diameter.
