Mushroom like fungus growing from my phalaenopsis orchid???

There are lots of thin, mushroom like things growing in the pot with my phalaenopsis orchid. I pull them out whenever I find one. They are never too far below the surface of the moss and seem to either be growing out of the moss or out of the orchid bark, and the "root" area is like a little white fuzzball, almost like mold or something. Any ideas? Should I repot the orchid right away? I've been raising orchids for almost 5 years now, and I've had this particular one for almost 4 years; I've never seen anything like this before.... thanks for any help!

Probably more Phalaenopsis are lost to pseudomonas, a bacterial disease, than to any other disease. The reason? Most hobby growers and some commercial growers use a fungicide when the disease is bacterial. Neem oil, Physan 20 or RD20 is a good control for bacteria as well as for fungus. Pseudomonas is very infectious and can be spread even by splashing water. All suspect plants should be treated . If the diseased area of the leaf is spreading, cut the area back 1/2 inch into the non-affected area. The whole leaf may need to be removed. Be sure to spray the entire plant with neem oil, Physan 20 or RD20, especially the cut area, as well as all plants that were near the diseased plant.





Fungus:The best prevention for fungal disease problems is a combination of:





a.good air movement;


b.keeping temperatures in an acceptable range; and


c.making sure plants (not potting medium) are dry before nightfall. If plants are not dry in late afternoon, spray the leaves with 2 teaspoons Physan or RD20 mixed in one gallon of water. This should dry the leaves and sterilize the plants.





The above care should eliminate fungus problems.





IF YOU WANT TO CHANGE THE POT DO THIS





Repotting Spray. In our greenhouses we use the following mixture to thoroughly spray the complete plant, especially the roots and any cut areas. Use it to spray the entire plant after removing it from the pot, and when repotting is complete to sterilize, give the plant a boost and to help prevent transplant shock. We use the repot spray first, and follow up by spraying with Neem oil solution.





Add to one gallon of water:


2 teaspoons Physan 20 or RD20


1 teaspoon water-soluble fertilizer


1/2 teaspoon SuperThrive
Reply:check your orchid is it affected,it is probably spores from moss.its harmless to the orchid it is wild flower.Dont repot observe first.You might do damage than good to your plant.
