Specimen notes
Public Note:
18th Fungal Foray of New Zealand; The collection was made at Eves Valley Scenic Reserve, a 15 minute drive from the Fungal Foray of New Zealand headquarters at the Teapot Valley Christian Camp on Teapot Valley Road \endash vegetation a mix of totora, beech and many other plants along several small streams.
Perithecia on dead wet decorticated totara, numerous, crowded, white mealy/floccose with a sulphur yellow centrum. Paraphyses numerous, filiform, septate. Asci clavate-cylindrical with 8 irregularly biserately/triseriately arranged ascospores (usually apically uniseriate), a small non-amyloid apical ring and a warty subapical globulus. Ascospores single-celled, hockey-stick-shaped [the apical \rquotehandle\lquote end slightly wider and more broadly rounded at its apex, the basal end (below the bend in the hockey stick) narrower and tapering to a more narrowly rounded apex], with a small tapered cauda at each end. Ascospores measured 54-64(-68) X 5 (n=10). Ann\lquotes herbarium number is 873. On 18-5-04 she isolated germinating ascospores and now has the specimen in axenic culture. It grows very restrictedly on potato carrot agar and has yet to be characterized. Miller and Huhndorf (citation below) report a Phialophora-like anamorph in culture.
Addendum: A recent publication treats Lasiosphaeria species in greater detail: Miller, A.N. and Huhndorf, S.M. 2004. Using phylogenetic species recognition to delimit species boundaries within Lasiosphaeria. Mycologia 96(5): 1106-1127. L. ovina (Pers. : Fr.) Ces. & de Not is described in detail. They place L. chrysentera Carroll & Munk among its synonyms. The primary difference between the Eves Valley Scenic Reserve specimen and Miller & Huhndorf\lquotes specimens is the length of the ascospores [54-64(-68) X 5 µm versus 35-55 (-60.5) X 3-6 µm, respectively]. The (?) that follows our species determination above is based on this size difference.
Worth noting are some comments in their Discussion section, p. 1123:
Lasiosphaeria libertiana is known from the two isotype specimens (BR and NY), which occur on decaying grass culms. This species is identical morphologically to L. ovina except it occurs on a different substrate (grass versus wood) and the ascospores are slightly longer (51-66 versus 35-55 µm) (TABLE II); the lengths of which fall within the 95% confidence interval of ascospore lengths in L. ovina. Until molecular data can be obtained for L. libertiana, it should be maintained as a distinct morphospecies distinguished from L. ovina by its unique habitat on grass and slightly longer ascospores. Ascospores of our specimen would seem L. libertiana-like yet our specimen was growing on decaying wood, not grass. An answer to whether our specimen fits into the molecular boundaries of Miller & Huhndorf\lquotes L. ovina might be better known if our axenic culture were sequenced?
