Introduction
Following our previous contributions to the knowledge of fungi of Dominican Republic
(, 2013a, 2013b, 2014, 2015, 2016 and 2018), here are represented other 30 records
not previously annotated. The collecting and research areas in the Dominican Republic have
been described in detail in ours previous works ( , 2013a, 2013b, 2014) and on
the website “Neotropical fungi - Hongos de la República Dominicana” (www.neotropicalfungi.com).
TAXONOMY
POLYPOROID FUNGI
Hymenium poroid, rarely lamellar (and hard); basidiomata often tough and coriaceous,
resupinate to pileate, sessile or stipitate (, 1989).
Family Hymenochaetaceae Imazeki & Toki 1948
2013a)
Genus Fomitiporia Murrill
Fomitiporia is above all characterized by globose to subglobose, thick-walled, cyanophilous
and dextrinoid basidiospores. Hyphal system dimitic (pseudodimitic); setae and cystidioles
variably present. Basidiomata resupinate or pileate (et al., 2014).
4
Fomitiporia maxonii Murrill [as ‘maxoni’]
Basidiome resupinate, pulvinate, inseparable, hard woody. Margin adnate, irregular, white,
sulphurous yellow, bright yellowish, yellowish brown to yellowish orange; pore surface greyish
brown, chocolate brown when dried, the pores circular, 7-9 per mm, the dissepiments entire,
thin; tubes concolorous, up to 2 mm deep; context thin, yellowish brown. Hyphal system
dimitic. Hymenial setae absent. Basidiospores subglobose, broadly ovoid to globose, hyaline,
thick-walled, dextrinoid, 5.6-6.6 (-7.2) µm in diam.
Distribution: probably widespread in the neotropics ( et al., 2007).
Material studied: on fallen trunk in a wood long the mountain river with deciduous trees,
21 Dec. 2018 - Jassica (P.to Plata) DR. Exiccatum: JBSD131257 (Fig. 1)
Remarks
F. maxonii shares with F. langloisii Murrill and F. neotropica
R.M. Silveira, Robledo et Decock the basidiospores size; F. langloisii
shaped basidiome, a lighter pore-surface color and slightly larger pores ( et al., 2007);
the distinction among asetose specimens of F. neotropica and F. maxonii is not unequivocal by
using classical morphological characters (, 2014). Moreover in F. punctata
complex, F. punctata (P. Karst.) Murrill and F. dryophila Murrill have distinctly larger
basidiospores ( et al., 2007). On the other hand according to et al. (2011), F. maxonii
can be positively determined only after DNA sequencing.
