spores 6-11 x 2-2.5 microns, cylindric with rounded ends, slightly curved, 2-seriate; asci 8-spored, up to 120 x 7 microns, clavate with slender stem, the pore blue in iodine; paraphyses slender, swollen to 5 or 6 microns wide at tip; meal consisting of globose cells 10-15 microns wide, (Dennis), spores 9-11 x 2 microns, allantoid [curved sausage-shaped], smooth, colorless, with 1 small droplet at each end, biseriate; asci 8-spored, 90-100 x 6 microns, amyloid; paraphyses "slender, with gradual clavate thickenings toward the tips to 5 microns"; detached excipulum cells 10-15 microns wide, rounded, brown, (Breitenbach), spores 8-10 x 2-4 microns, narrow-elliptic or allantoid [curved sausage-shaped], often with two small oil drops; asci 8-spored, reaching 80 microns long and 6-7 microns wide, narrowly clavate; paraphyses filiform but slightly enlarged in upper part, (Seaver)
Notes:
Encoelia furfuracea is found from NF to ID, CA, south to IA, and PA, and also Europe, (Seaver), including the United Kingdom (Dennis). There are collections from BC at the Pacific Forestry Centre and the University of British Columbia, and a collection from WA at the latter.
Habitat and Range
SIMILAR SPECIES
In addition to Encoelia pruinosa, Encoelia fascicularis has been recorded at least from BC (collection at Pacific Forestry Centre in Victoria): both occur on Populus.Habitat
singly or in small clusters on living branches of Alnus and Corylus, December to May, (Dennis for U.K.), emerging in small dense groups from bark of "still-standing dead trunks and branches of Corylus (hazel) and Alnus (alder)", often covering entire branches, December to March, (Breitenbach for Switzerland), in cespitose [in tufts] clusters of five or six, or more rarely singly, on branches of species of Alnus, (Seaver)
