Hi,Collected in October 1992 on decaying petioles of Petasites hybridus:
Perithecia superficial, gregarious, subglobose, flattened upper part, 0.3-0.4(0.5) mm diam., indistinct papillate, yellow-orange, with a crown of spreading, hyaline hairs.
Asci 8-spored, 73-83x9-10 µm.
Spores narrowly ellipsoid, 18-23(25)x5.5-7 µm, 1-septate, filled with 1-2 µm diam. guttules, smooth, hyaline.
Perithecial wall of textura angularis. Processes tapering, up to 115x13 µm, composed of agglutinated 2 µm diam. hyphae, hyaline.
Only a drawing available. Any idea? Thanks in advance.
Description of ascomatal wall, colour of perithecia in KOH as well as in lactic acid are required.
If there is no changing colour, you have choice among four genera:
Lasionectria, Lasionectriella, Ijuhya and Hydropisphaera, which are separated by characteristics of the cells composing the wall.
Did you see some orange, oily droplets in ascomatal wall or in hymenium?
Good luck
Christian
