83. * Hemitrichia pseudoleiocarpa Illana, G. Moreno, Lizárraga & A. Castillo , Oesterr. Z. Pilzk. 8: 64 (1999)

Specimen examined. PERU. Ancash: Huaraz, Jirac , route PE-14, km 97, 3529 m, 9º33′04.0”S, 77º40′23.9”W, 17 Apr 2013, leaves of Tillandsia sp. , Lado 22720 (MA-Fungi 94976) .

Notes. This species is difficult to differentiate from Arcyria leiocarpa , especially in the intermediate forms. The principal feature distinguishing between the two species was the orientation of the spirals in the capillitium, i.e., arranged from left to right in the specimens identified as H. pseudoleiocarpa , and in the opposite sense in those identified as A. leiocarpa .
