Remarks (public):Punctularia was by Talbot provisionally placed in Thelephoraceae, subfam. Merulioideae. He was well aware of the uncertainty and artificiality of the arrangement. The genus shows great resemblances to Laeticorticium, esp. in the presence of dendrohyphidia, nature of basidia and shape of spores. Also the nature of the hyphae is essentially the same. The difference remaining is the pigmentation of the dendrohyphidia, the subgelatinous consistency of the hymenial layer and the ability to form reflexed pilei of Punctularia. We leave the genera separate but consider it possible to include Laeticorticium as a subgenus in Punctularia.
