The perianth is inconspicuous and on the upper surface of the female receptacles are ribs alter- nating with the lobes (four or less). The peduncle is at first covered with hairs which mostly disappear except at base and apex. The spores are mature in early spring. This species is perhaps most likely to be mistaken for Marchantia because of its large size and stalked male Grimaldia GRIMALDIA. G. FRAGRANS (Balb.) Corda (G. sessilis Sulliv.) is distinguished by the peduncle, hairy at base and apex; female receptacle without alternating ribs, and antheridia in a disk im- mersed in the apex of the ihallus. The thallus also has purple margins and purple scales. Its spores mature in May, but in the autumn the spots from which the female stalk and receptacle develop are densely covered with slender white scales, forming a FlOUEB fragrans (After Bischoff.) , part of male and female whitish spot visible for several feet, plants; section of male disk; In Reboulia the scales are much female receptacle, etc. fg^er and are more like hairs!«^.
