a few weeks ago, while pulling up ivy, I noticed that with each pull, a poof of "something" came up up with the ivy. it didn't burn my skin. but, it did cause some mild eye watering and moderate coughing. then, a few days ago, while trying to complete the job, the same thing happened, with the addition of what can only be contact dermatitis. however, my fear is fungus. does anyone know what this irritating poof of "something" under the ivy might be? thanks in advance.
