Observation 84449: Melampsora Castagne
When: 2011-12-08
Who: Byrain
No herbarium specimen
0 Sequences

Notes:
On the leaves of a Populus sp. sapling, I’m thinking something like P. nigra. Most were attached to the tree, but the leaf the specimen photographed on was found on the ground. The spores are minutely echinate are greatly vary in length, less in width.

Range = (27) 30 – 53 (69) x (13) 14 – 20 (21)
Average Spore = 39.27 × 16.33
Average Q = 2.456
Spores measured = 30
