Xylodon cystidiatus (A.David & Rajchenb.) Riebesehl & Langer, Mycological Progress 16(6):645 (2017)

≡ Schizopora cystidiata A. David & Rajchenb., Mycotaxon 45:140 (1992).

Remarks.

We undertook a thorough morphological analysis of the specimen FR-0249200 ( Réunion, Plaine des Fougères, on fallen angiosperm twig, leg. E. Langer, 12 Sep 2013), because it provided the first sequences of X. cystidiatus . We are confident that FR-0249200 is X. cystidiatus , although we detected minor differences from the descriptions in David and Rajchenberg (1992) and Langer (1994). Some of the differences we noticed include: (1) the encrusted cystidia in FR-0249200 are mostly thin-walled with finer crystals; (2) the spores in our specimen were slightly broader 5-6 × 3.5-4.3 µm (L = 5.4 µm, W = 3.9 µm, Q = 1.4) than in published records 5-6 × 3-4 µm. Photographs of the basidioma (Fig. 11) and drawings of the microscopic features (Fig. 12) of FR-0249200 are provided for future identifications.
