Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. Archangelsky and J. C. Gamerro 1965 | Spore trilete. Rimosas lesuras externally outgoing and coming to Ecuador, but short in the inner layer. Equatorial outline circular to triangular circular. Distal Face convex and proximal face subconical. Cingulate slightly wider at the corners than on the sides. Esclerina composed of two layers, the outer part separate of the internal in the Ecuador and distal face more attached and thinner in the proximal face and lesuras. Outer layer forming lax and marked folds on the distal face, less conspicuous in the polar zone and more numerous and compact in Ecuador zone, giving the irregular crenulate cingulate look. Outer layer of texture alveolar in the proximal face and equatorial zone, which gives them an aspect retucylado; in lesura edges, the alveoli are elongated and parallel to it. Inner layer of uniform thickness, but with three circular thickening or elliptical of 4-5u in diameter x 2-3U, located at the proximal pole.
Total diameter 52,7-72,9 micrometers, 15 ej.; body centered diameter 40,3-58,9 micrometers, 13 ej.; Lesura length 18,6-34,1 micrometers, 8ej. Width of the cingulate: sides 4,6-9,3 micrometers, 13ej.; angles 6,2-10,8 micrometers, 11 ej.; polar diameter 31 micrometers, 1 ej. |
