(2002). Goidanichiella fusiforma sp. novo from palm fronds in Brunei and Thailand. Fungal Diversity 11: 119-122. Goidanichiella fusiforma sp. novo was identified from collections of decaying palm fronds in tropical rainforests in Brunei and Thailand. The new taxon is described and illustrated, and compared with similar taxa. Key words: anamorphic fungi, palm fungi, systematics, taxonomy. Introduction We are studying the fungi occurring on tropical palm species and have described several species new to science (Yanna et al., 1998a,b, 1999; Goh et al., 1999). Collections of fungi on fronds of palms in tropical rainforests yielded a new species of Goidanichiella and this taxon is described and illustrated in this paper. Taxonomy Goidanichiellafusiforma K.D. Hyde, Yanna, Pinnoi & E.B.G. lones, sp. novo (Figs. 1-7) Etymology: referring to the fusiform conidia. Mycelium immersa et superficialia. Conidiophora macronemata, mononemata, solitaria, erecta, recta vel paulo flexuosa, simplicia, laevia, brunnea, 240-300 x 6-9 Ilm, apicem subhyalina, apicem inflata 8-12 Ilm. Cellulae conidiogenae monoblasticae, determinatae, discretae, cylindricae, hyalinae vel pallid brunnae, 11-23 x 2-3 Ilm. Conidia acrogena, aggregata, hyalina, fusiformes, aseptata, laevia, 9-11 x 2.5-3 Ilm. Colonies scattered, sparse, brown. Mycelium immersed or superficial, composed of brown, septate, smooth, thin-walled, branched hyphae. Stoma absent. Setae and hyphopodia absent.

Bars: 1= 50~m;2-5= 10 ~m. mononematous, solitary, erect, branched at the apex forming stipe and head; stipe straight or flexuous, swollen at the apex, smooth, cylindrical, brown to dark brown, paler towards the apex, 240-300 x 6-9 Jlm (x = 255 x 8 Jlm,n = 25); apex forming a swollen head, 8-12 Jlm(x = 10Jlm,n =25), bears primary branches which themselves bear secondary branches arranged penicillately (Figs. 1, 6). Conidiogenous cells monoblastic, determinate, terminal, discrete, cylindrical, hyaline to pale brown, borne atthe endsof secondary branches, 11 23 x 2-3 Jlm(x = 12.5 x 2.5 Jlm,n = 25) (Figs. 2-4, 6). Conidia enteroblastic, aerogenous, solitary, aggregated in slimy heads, hyaline, fusiform, aseptate, smooth, 9-11 x 2.5-3 Jlm(x = 9.5 x 2.8 Jlm, n = 25) (Figs. 2-5, 7).

Pinnoi (Herb. BIOTEC, AOM 0008). Habit: Saprobic on fronds of Eleiodoxa conferta (petiole), Oncosperma horridum (rachis) andSalacca affinis (rachis), Known distribution: SouthEastAsia(Brunei andThailand). Notes: Goidanichiella was reviewed by Gams et al. (1990) and a single species G. barronii W. Gams, Steiman & Seigle-Murandi was accepted. Goidanichiella sphaerospora Matsush. had been invalidly published and the 121 type material lost. Goidanichiella fusiforma is distinct from G. barronii in producing relatively large, fusiform conidia (9-11 x 2.5-3 !lm). The specimen from Thailand had larger conidiophores (205-520 !lm long, 10-17.5 !lm diam.) with a narrower swollen head (5-7.5 !lm) and slightly shorter conidiogenous cells (9-12 x 2.5-3 !lm) and slightly longer conidia (11 x 14 x 2-3 !lm, = 11.9 x 2.7, n = 25). As the width of the conidia and conidiogenous cells are similar and the lengths overlap with those of the Brunei specimens, we are of the opinion that the Thailand specimen does not require separate species status.
