Name: Psilocybe acutipilea
Author: (Speg.) Guzmán
Citation: Mycotaxon 7(2): 226 (1978)
Deprecated Synonyms: Deconica acutipilea Speg.
The type specimen is contaminated with molds, so it was difficult to observe all features such as pleurocystidia, subhymenium, pileocystidia, and caulocystidia. Guzmán (1978, 1983) described subrhomboid basidiospores in frontal view; however, we observe that they can be ellipsoid and hexagonal, as well as subrhomboid, and in some spores the angles are not well defined. Furthermore, we found that the pileipellis is an ixocutis, and we describe the basidia characters. As Guzmán (1978, 1983) pointed out, P. acutipilea could be a synonym of P. mexicana R. Heim, due to the similar size and shape of the basidiospores, basidia, and cheilocystidia, although the poor condition of the type specimen makes the pleurocystidia difficult to observe and does not permit us to confirm synonymy.
