orrugulose; within white; below black and short rhizinose. Apothecia very 
numerous, small or medium, short pedicelled, disk concave, chestnut or dark 
brown, shining or opaque, with a concolorous slightly elevated dentate or 
crenate or verrucose at times inflexed margin, the exciple at length rugu- 
lose. Spores variable in number, at times only 8 in each theke. and again 
in the same thecium affording others with 12, 16, 22. 24, 28, 32, and accord- 
ing to Schneider 50 or 100 spores. The dimensions of the spores in the plants 
of my examination are 5 ~gX 5 ~ 7 ju but Schneider records 5x4//, and states that 
the spores are ellipsoid. Within my observations the spores are as often 
rounded as ellipsoid. 
Examined from Cathlamet, Washington, A. S. Foster, found on Acer 
circinatum and Crataegits sp. ; Spokane, Wash., T. A. Bonser on Crataegus 
Douglasii. Reported from Washington, Idaho and Utah. 
There can be no question of the affinity of this plant with P . olivacect 
rather than with P. taeniata as conjectured by Schneider. P. taeniata is a 
plant of the stock of P. ( Anzia ) colpodes . Rockland, Maine.
