Specimen notes
Public Note:
Parasitic, ascomata developing within brown spots on living leaves, gregarious on lower leaf surface. Ascomata 0.05-0.15 mm diam., appear to be superficial, with a poorly developed lower wall, upper wall of angular to globose dark walled cells, not arranged in an abvious radiate pattern. No surface mycelium, small amount of brown walled mycelium beneath the ascomata, this extending into the cell layer below the host epidermal cells, theough stomata. Asci globose, 11-12 um diam., bitincate with thickened apex, 8-spored. Ascospores 9-10 x 4-4.5 um, 1-septate, upper cells slightly larger than the lower cell, hyaline, some at least appear to be surrounded by a gel-like sheath, the sheath with granular inclusions. No paraphyses.
Keys out to Pachypatella in Arx & Muller 1975. The genus contains fern parasites, but this specimen is quite unlike the P. alsophilae specimen in PDD.

Public Note:
Two DNA extracts from ascomatal tissue gave identical ITS and LSU sequences. Closeest BLAST match for LSU is only 90%; incorporation into LSU phylogeny from Guatimosim et al. (Persoonia 35: 2301-241, 2015, http://dx.doi.org/10.3767/003158515X688046) places it sister to Asterotexis and Inocyclus angularis. Although these authors treat Inocyclus as incertae sedis because no type material studied, their order Asterotexiales is the best taxon for this fungus. [PRJ Jan 2019
