Three new hyphomycetes, Scalecobasidium excentricum, Soloacrospora microverrucosa, and Arachnophora uberisporoides, found on leaf litter in Cuba, are described and illustrated. The first species is characterized by cylindrical to worm-like, 3-5-septate, pale brown, eccentrically inflated conidia; the second species has fusiform, 0-1-septate, minutely verrucose conidia and lacks sterile setae. A. uberisporoides has conidia with two dark brown, globose central cells, from which several hemispherical, obtuse, subhyaline, unbranched, one-celled arms arise. A new combination, Arachnophora polyradiata, is proposed for Cacahualia polyradiata Mercado & Castaneda and the six species recognized in Arachnophora are keyed out.
