This orchid was given to me by a lady, who was disposing of all her orchids. After repotting this Cattleya(?) some of the roots needed cutting away, I noticed these 2 leaves, out of about 10 on the bulbs. The second picture is the underneath of same leaves. What is this? I get paranoid about viruses, especially when I have 40 orchids myself.Name:  IMG_1269[1].jpg
