Remarks (internal):On the basis of the shape and the size of the basidiospores, this collection belongs to P. lactea (P. leiocephala). The holotype fruitbodies are imperfectly matured, which causes the basidiospores to be more globose than typical in P. lactea. In our experience, the basidiospores reach their final rounded triangular or angled shape in the last stage of development, and accordingly no taxonomic value can be assigned to subglobose basidiospores in this case. Specimens with subglobose spores have recently been included in ITS- and LSU-sequence based phylogenetic analyses. With strong support from Bayesian, Maximum Likelihood, and Maximum Parsimony analyses, they were nested in the clade formed by P. lactea specimens (Nagy et al. 2009). That study strongly suggests that subtle spore shape differences should be regarded cautiously and that spore size should be given higher priority in defining the taxa of Parasola.
According to the original description (Watling 1967), the pleurocystidia are lacking, a statement that we cannot confirm here. Numerous utriform-oblong pleurocystidia were found on the sides of the gills. A lack of pleurocystidia would be surprising, as all but one collapsing species (P. misera) of Parasola possess pleurocystidia.
Roux & Garcia (Roux 2006) recently treated P. galericuliformis (and P. leiocephala) as a variety of P. plicatilis. However, our molecular and morphological results suggest that P. galericuliformis is synonymous with P. lactea (= P. leiocephala) a species distinct from P. plicatilis (Nagy et al. 2009).

Observations on the type - The holotype, which is in a good state, contains numerous fruiting bodies in different stages of maturity.
Basidiospores [20,1,1] 10-12 x 9.8-10.9 x 5.3-7.2 µm, on average 11.68 — 10.31 x 5.96 µm, Q1 = 1.02-1.25, Q2 = 1.66-2.10, strongly lentiform, in the frontal view broadly ovoid to subglobose, more rarely angular or rounded triangular, in the lateral view ellipsoid or amygdaliform, with an up to 1.8 µm wide, eccentric germ-pore, mainly immature, medium dark reddish brown, smooth, with a moderately thick wall; basidia four-spored, clavate, 22-27 x 8.5-11 µm; cheilocystidia abundant, lageniform, utriform or subcylindrical, 19-53 x 12-30 µm; pleurocystidia utriform, oblong or cylindrical, 40-82.5 x 15-27 µm; pileipellis hymeniform; veil, pileocystidia, and caulocystidia not found
