Fig. 32 Falciformispora lignatilis<br />
(from BRIP 16972, holotype).<br />
a Section of a superficial<br />
ascoma. The peridium comprises<br />
two layers. b, c Squash<br />
mounts showing asci with wide<br />
pseudoparaphyses. The asci are<br />
cylindro-clavate with very short<br />
pedicels. d–f Hyaline multiseptate<br />
ascospores. Note the elongated<br />
appendage at the base<br />
(arrow head). Scale bars:<br />
a, b=100 μm, c=50 μm,<br />
d–f=10 μm<br />
holotype). (Note: The specimen is not in good condition,<br />
only a few ascomata left).<br />
Notes<br />
Morphology<br />
Boise (1989) formallyestablishedHadrospora to accommodate<br />
Trematosphaeria fallax and T. clarkia (Sivan.) Boise,<br />
and Hadrospora fallax (syn. T. fallax) was selected as the<br />
generic type. Hadrospora is a widely distributed species that<br />
has been reported from Belgium, China, Italy, Japan,<br />
Switzerland and the United States (Boise 1989; Fisher and<br />
Webster 1992; Shearer and Crane 1971; Tanaka and Harada<br />
2003a; Webster 1993). Hadrospora was temporarily<br />
assigned to Phaeosphaeriaceae based on its “small, thinwalled<br />
ascomata and narrow cellular pseudoparaphyses”<br />
(Boise 1989), which is distinguished from other genera of<br />
Phaeosphaeriaceae by its “large, stout ascospores that form<br />
within oblong-ovoid asci” (Boise 1989). Currently, Hadrospora<br />
includes two species, i.e. H. fallax and H. clarkii<br />
(Sivan.) Boise differentiated by ascospore size.<br />
Phylogenetic study<br />
None.<br />
Concluding remarks<br />
Hadrospora seems not closely related to Phaeosphaeriaceae.<br />

Generic description<br />
Habitat marine, saprobic. Ascomata large, solitary, gregarious<br />
or confluent, broadly conical to subglobose,<br />
flattened at the base, carbonaceous, immersed to erumpent,<br />
ostiolate, epapillate. Peridium plectenchymatous.<br />
Hamathecium of dense, long, cellular pseudoparaphyses,<br />
septate, branching. Asci 8-spored, bitunicate, cylindrical,<br />
with a short pedicel. Ascospores uniseriate, ellipsoidal,<br />
subcylindrical or obtuse-fusoid, dark brown, 1-septate,<br />
constricted at the septum.<br />
Anamorphs reported for genus: none.<br />
