New member / little black growths on scaphosepalum

[Kristaz]

First time posting! I recently purchased two scaposeptalums from Andy's bare root sale. They are mounted, in my bathroom, (with my masdevallias) which has low but bright light, high humidity, good airflow and is on the cooler side. Probably 70F during the day, and about 60-65F at night. I bathe them all in large pots twice a week, and spritz when needed the rest of the time. Today, I noticed these little black "knobs" or growths at the base of my scaphosepalum. Any idea what they are? When I googled, I found nothing, and no pictures with them. Any input would be appreciated! I have about 30 orchids, but It is my first time growing this species so please be forgiving if this is an obvious growth habit ☺️
