Botrytis elliptica is a phytopathogenic mold from the genus Botrytis . It only attacks lilies ( Lilium ). Botrytis elliptica is an anamorphic .
description
The colonies are gray to gray-brown. Conidia carriers are plentiful. They are septate , branched and of a clear brown color. They grow to be 2 microns or a little longer.
The conidia are profuse, large, and elliptical. They are 6.5 to 12 micrometers long and 6 to 9.5 micrometers wide. In extreme cases, conidia can be nearly 30 microns long and correspondingly wide.
The sclerotia are black and smooth on the outside, but white on the inside. They reach a diameter of 1 to 1.5 micrometers.
ecology
Botrytis elliptica only thrives on lilies. There the leaves , petals and bulbs are attacked. Round or oval yellow to red-brown spots develop on the leaves that enlarge. A gray point sometimes forms in the center of the spots. These spots grow in damp weather and stagnate in drought.
Over time, the fungus spreads over the entire leaves, and the stem often breaks off at the point of infection. The sclerotia trickle from the leaves onto the ground and from there can infect plants again in the next year. Sclerotia are very rarely formed on the onions.
