Zopfiella erostrata
(Griffiths) Udagawa & Furuya, Trans. Mycol. Soc.
Japan
15(3): 208 (1974)
(
Plate 1
, Fig. 30)
Ascomata
non-ostiolate, scattered to gregarious, semi immersed to superficial, globose, metallic black in stereomicroscopy, dark brown to black in mounting, 300–450 μm diam.
Hairs
setose, simple, thick-walled, septate, smooth, dark brown to black, becoming less pigmented to near hyaline towards the apex, 4.8–6 μm diam. at the broadest part.
Peridium
pseudoparenchymatous, membranaceous, opaque, composed of angular (
textura angularis
), brown to dark brown, thick-walled cells.
Asci
8-spored, clavate, evanescent, irregularly biseriate, only observable in young cleistothecia.
Ascospores
1-celled, lageniform to clavate and hyaline and when young, smooth, becoming swollen and forming a transversal septum to delimit a head and pedicel.
Head cell
subglobose, ovoid or lageniform, with umbonate apex and truncated base, smooth, brown to dark brown, 7.5–12.5 × 6–8.5 μm, guttulate, with a subapical germ pore.
Pedicel
cylindrical, thin-walled, occasionally collapsing, with rounded base, 6–10 × 2.5–5 μm.
Apical caudae
absent.
Basal caudae
absent.

Notes
:—
Zopfiella
can be distinguished from other coprophilous lasiosphaeriaceous, which share similar ascospore morphology, due the presence of non-ostiolate ascomata with ascospores forming a head and a tail, occasionally with septate heads (previously allocated to
Tripterospora
Cain
).
Zopfiella erostrata
is a common representative of this genus on herbivore dung. The material from
Pernambuco
had a limited number of mature cleistothecia on the substrates, which were identified based on key characters such as ascomata with long dark brown to black, thick-walled hairs and ascospores with symmetrical head cells, differing from
Z. longicaudata
by the shorter pedicel, (6–10 × 2.5–5 μm.)
