Figure Fig. 1 5-day-old colony on PDA Fig. 2 Hormographiella aspergillata. a–c. Conidiophores. d. Sclerotia. e. Arthroconidia (Bars= 5 μm, unless otherwise specified)
Colonies Colonies on PDA growth moderate, attaining 33.5-, 50-, 55-mm at 24 °C, 28 °C and 37 °C in 10 days respectively, margins entire, cottony, reverse white to cream.
Conidiophores Conidiophore macronematous, hyaline, 25–45 × 3–4.5 µm, bearing a cluster of conidiogenous hyphae which will turn into arthroconidia later.
Conidia Conidia uni-nucleate, hyaline, smooth, cylindrical, truncated at both ends, 3–6 × 1.5–2.5 µm.
Sclerotia Sclerotia produced in old culture, spherical, brown, up to 180 µm in diameter.
Note This is the asexual state of a common mushroom Coprinopsis cinerea. Surprisingly, a mushroom can occur on rice grain. The vegetative mycelium of this species has been reported to have the clamp connection (Conen et al., 2011), which is not observed on strain 12021. This implies that this strain may be monokaryotic. Strain 12021 shares 99.82% and 100% identities in ITS and LSU regions with the ex-type strain of Hormographiella aspergillata (CBS 519.91; MH862274, MH873955).
This species can be distinguished from H. verticillata by the production of sclerotia and shorter, cylindrical conidia.
