Hypomyces subiculosus (Berkeley & Curtis) von Hohnel

Anamorph:

Cladobotryum sp.

Teleomorph in nature: Subiculum orange to deeporange, covering a part or entire surface of host hymenium; Perithecia yellowish brown, in KOH lilac to red, ellipsoid to longellipsoidal, 264-277 x 238-277 μm. Asci cylindrical, 8-spored.  Ascospores hyaline, fusiform, always equally two-celled, 14.0-17.5 (-18.5) × 5.0-5.5 μm, verrucose with prominent warts, apiculate at both ends. 

Characteristics in cultures: Colonies on MA grow rapidly to reach 90 mm in diam. after 7 days at 25oC, floccose, white; mycelium partially composes a dense mat, producing sclerotia, orange, which turn out. to be perithecia (21d); reverse orange.  Conidiogenous cells born at the laterally or as a main branch of conidiophores, solitary or in a whorl, hyaline. Conidia produced retrogressively in long imbricate chains from the apex of conidiogenous cells, hyaline 0-1(-2)septae, cylindrical to long ellipsoidal, thin-walled, smooth (12.0-)16.0-19.0(-21.5) × (3.0-)5.0-6.5 μm.Chlamydospores produced in chains laterally on the substrate hyphae or apically at the apex of the branches, subglobose to broadly ellipsoidal.
