Some species of Hyphodontia s.l. with encrusted cystidial elements

Some species in Hyphodontia or related genera with encrusted cystidia are discussed. The type specimens of the following species have been studied: Grandinia erikssonii, Hyphodontia heterocystidiata, H. wrightii, Hypochnicium odontioidescens, H. rickii, Palifer seychellensis, and Peniophora verecunda. All all them except P. seychellensis, belong to Hyphodontia s.l. Based on morphological characters of the generic type, Palifer could be considered a synonym of Xylodon.
